Unfortunately, radon can enter your home fairly easily and through many different venues. Since radon is present in the air, water, soil and rocks, there are many avenues through which radon can enter the home. For instance, radon from spoil can seep through cracks in flooring; from there, radon gets into the air and will spread throughout the home. Radon can enter the home through groundwater pipes, cracks or small cavities inside walls, and even through sump pumps.

#2: Radon is responsible for cancer-related deaths

Did you know that radon is actually the second leading cause of lung cancer in the United States? Next to smoking, radon is a major factor in the development of lung cancer . When radon is breathed into the body, over time, the radioactive particles that comprise radon will become trapped inside your lung. This may then develop into lung cancer, a serious and often fatal type of cancer. The more time you spend in a room with radon, the higher the chances that radioactive particles will become stuck in your lungs.

#3: Radon cannot be detected without testing

Radon is colorless, odorless and cannot be detected with your eyes, ears, mouth or any other senses. There is only one way to find out if there is excess radon in your home or any other space: testing.

#4: 1 in 5 homes have elevated radon levels

In the United States, it is estimated that about 1 in 5 homes have elevated radon levels . This means that 1 in 5 households are being exposed to high levels of radon that may severely increase their risk for developing lung cancer. This startling statistic is a good example of why radon testing is such an essential action to take, especially if you have never had your home or business space tested for radon.

#5: There is no safe level of radon

There is no safe level of radon, so it is very important to make sure that you test for radon in both residential and commercial spaces. You should also do what you can to decrease the chances of high radon levels in your home, including: sealing cracks and crevices inside floors and walls; covering dirt floors underneath homes or garages with plastic sheets and installing vent pipes that will ventilate radon from the dirt outdoors; and using vents and circulation fans to improve air circulation in the home.

Rust Never Sleeps: Understanding Corrosion and Its Impact on Materials

Wed, 25 Oct 2023 09:59:23 GMT

The Silent Culprit That Erodes Material Integrity

When it comes to material integrity, one of the most insidious adversaries is corrosion. Often lurking beneath the surface, corrosion can silently compromise the structural strength and safety of materials used in a wide range of industries. In this blog post, we explore the relentless nature of corrosion and its far-reaching impact on materials.

Unveiling the Corrosion Process

Corrosion is a natural process that occurs when metals are exposed to environmental factors, such as moisture, oxygen, and contaminants. Over time, these elements initiate chemical reactions that weaken and deteriorate the metal's surface. As corrosion advances, it can penetrate deeper into the material, leading to structural flaws and a reduction in load-bearing capacity.

Forms of Corrosion

Corrosion comes in various forms, each with its unique characteristics and effects. These include:

Uniform Corrosion: This is a general and even attack on the entire surface of a metal. It often results in the thinning of the material, which can lead to catastrophic failure if not addressed.
Pitting Corrosion: Pitting occurs when localized areas on the metal's surface deteriorate, creating small holes or pits. While these pits may appear minor, they can significantly compromise the material's integrity.
Galvanic Corrosion: This type of corrosion occurs when two different metals come into contact in the presence of an electrolyte. The more noble metal remains relatively unaffected, while the less noble metal corrodes rapidly.
Crevice Corrosion: Crevice corrosion takes place in narrow gaps or crevices where stagnant solutions are trapped. It can lead to localized corrosion damage.
Stress Corrosion Cracking: Stress corrosion cracking happens when a combination of tensile stress and a corrosive environment causes cracking in the material. This can lead to sudden and catastrophic failure.

The Impact on Materials

The effects of corrosion on materials can be devastating. Beyond the visible signs of deterioration, corrosion can lead to structural weaknesses, reduced load-bearing capacity, and an increased risk of catastrophic failure. In industries like construction, aviation, and manufacturing, the consequences of corrosion can be life-threatening.

Preventing and Managing Corrosion

Preventing and managing corrosion is paramount to ensuring material integrity. Effective strategies include:

Protective Coatings: Applying protective coatings can shield materials from the environmental factors that trigger corrosion.
Cathodic Protection: This technique uses a sacrificial anode to attract corrosion, preserving the material it shields.

History of Non-Destructive Testing

Tue, 21 Feb 2023 04:07:24 GMT

Non-destructive testing has come so far since its beginning!

Non-destructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components, or assemblies without causing damage. This technique has been used in various industries for many years, and its development can be traced back to the 1800s.

The history of NDT dates back to the early 1800s when visual inspection was used to detect surface cracks on metal parts. The first non-destructive testing method used was the magnetic particle inspection (MPI), which was developed in the 1860s. MPI involves placing a magnetic field around the object being inspected, and then applying iron oxide particles to the surface. The particles collect at the site of any cracks or defects, making them easily visible.

In the early 1900s, the ultrasonic testing (UT) technique was developed, which uses high-frequency sound waves to inspect materials. The first practical application of UT was for detecting defects in armor plates used on naval vessels during World War I. UT quickly became a widely used method for non-destructive testing, and it is still used today in a variety of industries, including aerospace, automotive, and manufacturing.

In the 1920s, the dye penetrant inspection (DPI) method was developed, which involves applying a liquid dye to the surface of an object and then wiping it off. The dye is drawn into any surface defects, which are then visible under UV light. DPI is still used today for detecting cracks and other surface defects on a variety of materials.

During the 1940s and 1950s, radiography was developed, which involves passing X-rays or gamma rays through an object and capturing the resulting image on film. Radiography is still used today, and it is one of the most widely used non-destructive testing methods for detecting internal defects in materials.

In the 1960s, eddy current testing (ECT) was developed, which involves inducing an electric current in a conductive material and then measuring the resulting magnetic field. ECT is used to detect defects in conductive materials, such as metal pipes and tubing, and it is also used to measure the thickness of non-conductive coatings on conductive materials.

Over the years, new non-destructive testing methods have been developed, such as acoustic emission testing, digital radiography, and computed tomography. These new methods have improved the accuracy and speed of non-destructive testing, making it an essential part of many industries today.

In conclusion, the history of non-destructive testing is long and rich, with many different methods being developed over the years.

Preparing for Liquid Penetrant Testing

Thu, 26 Jan 2023 13:06:02 GMT

Liquid penetrant testing is a valuable form of non-destructive testing widely used across many industries.

What is Liquid Penetrant Testing?

Liquid penetrant testing (LPT) is one of the most popular non-destructive examination (NDE) methods in the industry. It’s both economical and versatile. LPT’s a testing method that uses liquid and developer to reveal flaws within a material. Liquid penetrant testing checks for material flaws open to the surface by flowing very thin liquid into the flaw and then bringing the liquid out with a developer making the flaws visible and known. It’s popularly used in the welding industry as welds are the most common item inspected. However, plates, bars, pipes, castings, and forgings are also commonly inspected using liquid penetrant testing.

The Significance of LPT Prep

Liquid penetrant testing is complicated in a way that if the preparation is not done right it can produce poor, inaccurate, or faulty results. Extensive measures must be taken to prepare the material to ensure that the inspection is performed successfully. Poor preparation of the testing material can result in problems such as unfound cracks and flaws, which will end up costing more time and money.

There are both advantages and disadvantages to liquid penetrant testing. See both the advantages and disadvantages listed below.

Advantages

LPT is very effective in detecting porosity, cracks, fractures, laps, seams, and other flaws that are open to the surface. There are only a few types of materials that cannot be inspected using liquid penetrant testing. LPT is fairly quick and isn’t too costly. Large areas and large volumes of parts and materials can be efficiently and effectively inspected.

Here are some other advantages:

High sensitivity to small surface discontinuities
Easy inspection of parts with complex shapes
Flaws are visual and clearly indicated on the part surface
Inspection process is conveniently performed onsite
Indications can reveal relative size, shape, and depth of flaws

Disadvantages

One of the main disadvantages of LPT is that only flaws open to the surface can be detected. Materials with porous surfaces cannot be examined using this process. Only clean and smooth surfaces can be inspected. Any rust, dirt, paint, oil, or grease must be removed prior to beginning the testing.

The Process of Liquid Penetrant Testing

1. Clean the Surface

The cleaning process of liquid penetrant testing differs and depends on the specific testing material or part. Sometimes pre-cleaning may include grinding and wire brushing, whereas other times simply wiping down the part with a rag and cleaner is enough. Bottom line is that the surface needs to be free of dirt, rust, paint, oil, and grease , and smooth enough to wipe off the penetrant without leaving residue.

2. Apply the Liquid Penetrant

Liquid is generally applied by an aerosol spray from the can. It can also be applied with a brush. The liquid must soak or dwell on the material for some time to allow for the penetrant to permeate into cracks and voids. This usually takes between 5 to 30 minutes.

3. Remove Extra Penetrant and Apply Remover

The liquid penetrant needs to be completely removed with a clean, dry, and lint-free rag until thoroughly clean. The part or material should be rubbed and wiped clean until the liquid is not visible on the dry rags. Then a cleaner or remover is sprayed on a clean rag and used to vigorously rub the part or material again until there is no liquid visible on the rag.

4. Apply Developer

A very light coating of developer is sprayed onto the part or material being examined. The dwell time for developer is typically 10 to 60 minutes.

5. Inspection

Inspecting the surface is time sensitive. Surface level flaws that are visible should be noted.

6. Clean the Surface

Finally, the part or material needs to be cleaned to remove all developer after it has been evaluated. Post cleaning is just as important as pre-cleaning.

All About Radiographic or X-Ray Testing

Wed, 23 Nov 2022 07:17:41 GMT

Radiographic testing has extensive value in identifying and improving flaws in material.

Radiographic Testing (RT) is used to detect surface and subsurface flaws, and produces a permanent image of these flaws. RT, or industrial radiography, is a testing method which utilizes short wavelength electromagnetic radiation (photons) to penetrate various materials and detect hidden flaws. There are two different radioactive sources available which are X-ray and gamma ray . The radiation source and strength depends on material thickness and the size of the component.

This testing method can be utilized multiple times over a component's service life, which will show gradual change in the size and shape of the discontinuities. RT is widely used in a variety of industry sectors such as the aerospace industries, military defense, offshore industries, marine industries, petrochemical industries, waste management, automotive industries, manufacturing industries, power generation, construction, petroleum, and chemical.

RT is commonly used for welded parts, forgings, castings, corrosion mapping, detection of blockages in sealed equipment, measuring porosity in concrete, and many other things. Some benefits of radiographic testing is that it can inspect assembled components, minimize surface preparation of test pieces, verify internal flaws on complex pieces, isolate and inspect internal components, and much more.

Other advantages of radiographic testing include:

Inspection capability for many types of material with varying density
Determination of crack growth
Detection of both surface and subsurface defects
Permanent record of the inspection

There are some limitations to RT, which are:

Hazardous ionizing radiation requires creation of safety perimeter
Sensitive to flaw orientation
Usually not possible to determine depth of indications
Two-sided access to test object is required

Radiographic testing is extremely valuable in the non-destructive testing industry because it provides an image that can be referenced back to in order to make proper improvements. The images deliver clear, reliable, and authentic results.

Below is the step-by-step process of radiographic testing in welding:

Step 1: A radioactive isotope produces gamma rays or X-rays
Step 2: The radiation is sent through the weldment onto photographic film
Step 3: An image of the internal structure of the weldment is created on the film
Step 4: Darker areas of the image reflect thinner portions of the weldment, suggesting discontinuities like cracking or porosity, a common flaw found in welding - lighter areas of the film may suggest high density inclusions
Step 5: Radiographic interpreters trained to read the films and identify weld discontinuities by the shape and variations of dark and light examine the test results

Though radiographic testing may seem like a simple, straightforward form of non-destructive testing, it requires intense training, knowledge, and experience. It’s important that only NDT professionals conduct and interpret radiographic testing to ensure the results are accurate.

Steel City NDT provides high quality NDT services, including radiographic testing, throughout Pittsburgh and the surrounding areas. Steel City NDT is happy to help you find the perfect solution and provide you with accurate testing results you can rely on. Call Steel City NDT to discuss the needs of your project!

Understanding Electromagnetic Induction

Wed, 26 Oct 2022 01:43:45 GMT

Electromagnetic induction is an inspection process of inducing electric currents, magnetic fields, or both inside a test object and observing the electromagnetic response. If the test is set up properly, a defect inside the test object creates a measurable response. The measurable response differs from the background noise and allows the tester to detect and characterize surface and sub-surface flaws in conductive materials. EM can detect cracks, measure material thickness and coating thickness, as well as provide conductivity measurements.

Electromagnetic induction is a highly effective and successful method at identifying flaws and defects underground that cannot be visible without digging. To avoid wasting time and resources digging, electromagnetic induction can be paired with other underground technology, such as ground penetrating radar , to map out the ground underneath the surface to better understand the layout of the land. EM is best utilized in large lots, including fields and asphalt covered lots.

Below is a list of the advantages and disadvantages to electromagnetic induction:

Advantages

Portable equipment can be utilized on-site
Faster than other methods – saving both time and money
Can detect through several layers
Little prep required
Accurate measurements
Immediate results

Disadvantages

Susceptible to magnetic permeability changes
Only effective on conductive materials
Will not detect defects parallel to surface
Limited depth of penetration
Signal interpretation required

Despite these disadvantages, the technique of electromagnetic inspection is highly effective and successful at providing accurate results and measurements of the testing site. As long as the EM equipment is set up and conducted properly, the process of electromagnetic testing should be fairly smooth. Of course, this all depends on hiring a reputable and respected team of NDT professionals that’s experienced and knowledgeable about providing underground testing services.

Steel City NDT is a professional non-destructive testing company with experience and training in underground services such as borescope visual inspection, electromagnetic induction, ground penetrating radar, leak detection , utility location, and more!

Magnetic Particle Inspection and Its Role in NDT

Fri, 30 Sep 2022 20:00:10 GMT

A very common and reliable non-destructive testing method is magnetic particle inspection.

Magnetic particle inspection ( MPI ) is a non-destructive testing method that is used to locate surface and near surface defects such as cracking, pores, cold lap, and other flaws in ferromagnetic materials such as iron, nickel, and cobalt. Magnetic particle inspection is very effective and accurate at detecting and determining whether a magnetic field has flaws.

There is a process to magnetic particle inspection, which involves putting a magnetic field into the test object. Flaws will be detected when the magnetic field flowing through the test object is interrupted and there is flux leakage. Ferrous iron particles are then applied to the object in a dry or wet suspension and will be attracted to the flux leakage. This step-by-step process includes pre-cleaning of the test object to remove any rust, dust, oil, and grease, introduction of magnetic field, and application of ferrous iron particles. As described, it takes a series of steps to successfully complete. With that said, there are both advantages and disadvantages of MPI.

Advantages

MPI is described as a fairly easy and fast form of non-destructive testing that provides immediate results. With magnetic particle inspection, defects are directly visible on the surface and even the distinct shapes and sizes of the flaws are indicated. It’s a convenient and versatile form of NDT because it involves portable, low cost equipment. Magnetic particle inspection is safe when completed by a professional. It’s extremely important that the professional conducting the magnetic particle inspection is well trained, educated, and experienced in non-destructive testing.

Disadvantages

Though there are many advantages to MPI, there are a few disadvantages. The major drawback to magnetic particle testing is that it’s restricted to ferromagnetic material only. Meaning, non-ferrous material cannot be inspected using the magnetic particle testing method. In addition, only small sections can be tested at a time and material with heavy coats of paint will need to be stripped before testing begins. After testing takes place, the material must be demagnetized, which can present challenges. Magnetic particle testing may have disadvantages, but they are far outweighed by the advantages of MPI.

Overview

Magnetic particle inspection is a very well known and popular form of non-destructive testing. It is commonly used in the automotive, oil & gas construction, chemical, structural steel, aerospace, and pipeline industries. MPI was developed in the United States and is currently growing more popular across the world. It’s a reliable and affordable method to determine the quality of ferromagnetic material and identify flaws on surface and subsurface levels. The most valued feature of magnetic particle inspection is that it produces immediate results and it’s an easily transportable test.

Of course, with any form of testing and inspections you want to be sure to hire a team of professionals that is experienced and fully dedicated to satisfying their clients. Steel City NDT provides high quality NDT services, including magnetic particle inspection, throughout Pittsburgh and the surrounding areas. Call to discuss the needs of your project! Steel City NDT is happy to help find the perfect solution.

The Value of Visual Inspections

Fri, 12 Aug 2022 01:51:43 GMT

Visual Inspection (VT) is the oldest and one of the most reliable non-destructive testing methods out there. It can be applied to nearly any product and is extremely useful when monitoring the maintenance and condition of an asset. Visual testing is a basic form of inspection, which involves the examination of an area, piece of equipment, or component with the naked eye. Sometimes tools such as mirrors, borescopes, magnifiers, and lights are used to help inspect and identify any anomalies. Though it may seem old fashioned, visual inspection is effective across many industries, especially the welding industry.

Cost

Visual inspection does not involve the use of high powered technology, which reduces the cost of testing. VT is relatively low cost when compared to other non-destructive testing methods. Visual inspection involves the use of an experienced and educated professional that has been trained to examine and point out imperfections with the area being inspected. The cost to perform visual inspections is relatively low compared to other NDT testing methods. In addition to the cost benefit of visual inspection, VT is also highly effective at determining the strengths and weaknesses of fabrications, material, and components.

Effectiveness

Visual inspection is a reliable and trusted non-destructive testing method. It’s been around for decades and has allowed progress to be made across many industries. Over the years, VT has been found to be highly effective at about 87% effectiveness ( Juran’s Quality Handbook ). Of course, this is heavily dependent on the training, education, and experience of the NDT team performing the testing services. To increase effectiveness, the use of small tools and technology such as illuminators, cameras, magnifiers, and more may be utilized during inspections.

Education

The key to obtaining a high quality, accurate visual inspection report is to do your research. A company providing NDT testing services should be well trained and educated. A non-destructive testing company should be continuously training and educating staff to stay up to date and current with visual inspection and other NDT methods. To find a company that meets these standards, ask the important questions, check out their website, look at the reviews, and thoroughly research. A company that is dedicated to education is likely also experienced within the NDT industry.

Experience

Experience comes with time, exposure, and commitment. Since visual inspection relies almost completely on the naked eye, the naked eye must be experienced to properly inspect and effectively identify anything wrong with the asset. This experience is only obtained through time, on the job training, and exposure.

There are many advantages to visual inspection. Visual inspection is one the most trusted way to find any flaws of an asset. VT is used very often because it’s fairly low cost and relatively simple to perform. Though, it’s critical the individuals performing the visual inspection testing are well trained, educated, and experienced with visual inspection. If not, a flaw could be missed during the inspection and cause issues later on. VT searches for quality, strength, and confidence of the material or component being inspected. In the welding and fabricating industry, visual inspection is the most common testing and inspection method used to determine the condition of a weld.

The Process of Dye Penetrant Inspections

Wed, 13 Jul 2022 00:55:15 GMT

Liquid Dye Penetrant inspections can often be performed on-site and is a form of non-destructive testing (NDT).

Dye Penetrant testing is a method used to inspect surfaces and identify any defects. It is a common form of inspection in non-destructive testing and is highly effective at determining whether a weld is strong or faulty.

So what is dye penetrant testing? How does it work and what is the process?

First, dye penetrant testing is often also referred to as liquid penetrant or liquid dye penetrant. It is considered a non-destructive testing (NDT) method because a Level II Inspector can perform this type of testing and make important determinations about the material without causing any damage or alterations to the testing subject.

To perform dye penetrant testing the inspector uses liquid or dye to apply to a surface. The liquid dye is carefully spread throughout the surface and as that takes place the inspector will look for any areas in which the dye may penetrate any cracks and reveal any discontinuities on the surface of the material.

Non-porous materials such as metal, ceramic, and plastics are commonly inspected using dye penetrant testing. Specifically, in these materials inspectors are working with welds, forging, bars, pipes, castings and plates. With dye penetrant inspectors are looking for leaks, joint flaws, fractures, porosity, incomplete fusion and of course, cracks.

There are many pros to dye penetrant testing:

Inexpensive
No damage done
Simple to perform - mostly onsite
Flaws are easily found and identify dimensions of defects clearly
Testing process is versatile and flexible with various types of materials
Quickly covers large areas

Of course, it's important to keep in mind that dye penetrant testing reveals surface level findings. It can only be performed on non porous and clean material (without rust or paint). While dye penetrant testing is non invasive and doesn't cause any damage, chemicals are still involved. Dye penetrant testing can be dangerous, which is why only experienced professionals should perform dye penetrant testing.

Steps of Dye Penetrant Testing

1. Clean the Surface

The material must be cleaned well so the liquid dye can penetrate any possible flaws. Any dirt or film will be removed during this step with a wet rag, solvent or perhaps a grinder or wire brush.

2. Apply the Dye Penetrant

The liquid dye penetrant is then applied by either spraying or wiping onto the surface. The inspector then waits a certain amount of time for the dye to dry, this is called the “dwell period” .

3. Remove Excess Liquid Penetrant and Apply Remover

The inspector will remove any extra liquid dye penetrant. Then the remover is applied with a clean, dry rag.

4. Apply Developer

Once the excess penetrant is wiped away and the remover is applied, a white developer is applied next. The developer will reveal any dye that has penetrated defects and make them visible to the naked eye.

5. Inspection

At this time the inspector will then thoroughly inspect the material. All surface level defects will be visible and noted.

6. Clean the Surface

After inspection takes place the material is ready to be cleaned to return it to its original condition before testing.

Dye penetrant testing is an NDT inspection method that is reliable in discovering flaws in non-porous surfaces. It is inexpensive, simple, and relatively fast to perform.

Fun Fact: Dye penetrant testing was first used in the railroad industry early on in the 20th century. Of course, the liquid penetrant process has been developed and perfected over the years.

If you are in need of dye penetrant testing or any other NDT service , Steel City NDT is equipped with highly reputable and experienced inspectors with the proper resources to successfully complete any job. Call today to learn more about Steel City and its many specialties!

What is Leak Detection? How Does it Work? When is it Needed?

Wed, 15 Jun 2022 16:11:02 GMT

Leak detection ensures safety, reduces the waste of resources, and prevents further damage.

Leak detection reveals critical information about underground and other related situations. With leak detection, we are able to find more about what we cannot see above ground or behind walls, tanks, and in other situations. Leak detection is designed to identify cracks or holes causing liquid, gas or any other substance to leak. With that said, leak detection is significantly important because it evaluates safety, reduces costs, and minimizes leak issues from getting worse. With this high level of importance and the growth of development in the world, the demand for the leak detection and repair industry is increasing at a rapid rate.

Leaks, as we know, can be very dangerous, which is why it is important to continue to monitor and test for leaks. With underground piping in place, continuous leak detection is extremely necessary and a major part of safely maintaining such systems. Understanding whether there is any leak or escaping material will allow for the containment, control, and elimination of such leaks. Leak detection is an essential part of installing and maintaining piping systems. There are many methods of detecting leaks and each method is specifically designed to serve a different purpose or apply to a specific situation.

There are three common types of leak detection systems, which are chemical, pressure, and acoustic. Acoustic is a form of non-invasive leak detection. Non-invasive leak detection is especially important because it involves the use of leak detection equipment without having to dig or drill. This leak detecting method eliminates the cost of damaging property or structures, as well as using workers to operate the machinery and equipment to dig or drill.

Leaks produce high frequency sounds. Acoustic leak detection involves a device or sensor that records sound waves. Acoustic leak detection is able to remove any and all background noise to properly identify and quickly locate a leak. The difference in the sound indicates the type of leak, such as whether it’s a crack or hole, its size, and the material leaking. A lot can be discovered with acoustic leak detection and with absolutely no damage done to the building or work area. It provides valuable information to the development team and other involved parties such as state, or government agencies which may require such testing and monitoring.

Systems that transport fluid or gas material always have the potential to develop leaks, cracks, and holes. These systems need consistent leak detection and monitoring to ensure safety, reduce the use of resources, and minimize further damage.

Non-invasive leak detection is the modern approach to detecting and locating leaks . Acoustic leak detection saves time, resources and increases safety. At Steel City NDT, safety is a top priority. We use top leak detection equipment to get the job done effectively and efficiently. If you are in need of leak detection services, Steel City NDT is Pittsburgh’s top non-destructive testing team with years of experience.

The Important Role of a Certified Welding Inspector (CWI)

Thu, 19 May 2022 00:55:10 GMT

Read Why Certified Welding Inspectors are Essential to All Types of Building Projects

Welding, in many ways, is everywhere. Once the art of welding is understood, along with it comes a great appreciation for the workmanship and value of the profession. A Certified Welding Inspector (CWI) holds a key role in the welding industry. A CWI is a skilled professional responsible for examining welds, and determining their quality and strength, among other things. It is a highly important job, as welding is a vital part of infrastructure, building construction, vehicle manufacturing and much more. A CWI is not only responsible for inspecting welds, but is also involved throughout the entire process of welding from start to finish.

Before Welding

Prior to starting the welding process, a CWI is involved in reviewing all set plans among all parties involved. A CWI ensures compliance with all qualifications, job codes, safety standards and regulations. Lastly, before any fabrication begins, the metal materials are inspected for compliance with welding procedure specifications (WPS) as well as project specifications and even, review heat requirements, joint fit-up, and environmental conditions.

During Welding

During welding, the CWI is involved closely with the welding process, as he or she will be watching for adequate fusion, proper interpass temperatures, travel speed, cleaning and welding deposit size. Visual Inspection during the welding process is a major component of guaranteeing the weld quality and its strength. Inspection during the welding process will check to make sure the joint fit-up was correct, the proper material was used and the weld passes were cleaned.

After Welding

After welding, the Certified Welding Inspector will visually examine welds by utilizing electrical instruments and visual tools to inspect welds to ensure they are properly executed. The CWI will inspect for incorrect welding techniques or improper current settings, which may cause cracks, porosity, incomplete fusion, undercut, etc. If any of these are found during inspection, the welds would be considered defective, and would need to be repaired or completely scrapped and replaced.

Tools

In order for a Certified Welding Inspector to successfully perform his or her job , the CWI will need to operate a set of tools. During inspection, a CWI may use a flashlight, measuring tape, magnifying glasses, a variety of gauges to determine any discontinuities of a weld .

Professional Skills

In addition, there is a vast set of professional skills that a CWI also needs in order to lead a successful career. A successful CWI is an effective communicator, works well with others and is able to deliver clear instructions. He or she is confident in their ability to make decisions and speak openly with multiple team members, and those involved with the project.

AWS Certification

The American Welding Society (AWS) provides certifications to welding inspectors through an in depth six-hour three-part certification exam. In order to earn the CWI certification, individuals must score 72% or more on all three parts. Becoming a Certified Welding Inspector is in no way easy and requires continuous education. CWIs are held to a high standard and relied on to be good at what they do.

A good Certified Welding Inspector is someone who takes his or her work seriously. A CWI is someone who is highly experienced and knowledgeable. A CWI is responsible for inspecting the quality of welds, adhering to project plans and job code requirements and essentially ensuring the safety of the general public. CWIs are accountable for every single one of their inspections, and accountable to the employer, investors, and users of the finished project. Since the role of a CWI has such immense responsibilities, the profession requires extensive experience, education, training and dedication. A Certified Welding Inspector is an important role that requires trust.

Before You Dig: Utility Location

Thu, 28 Apr 2022 02:51:31 GMT

Before you dig, call a Professional for an NDT Inspection.

Are you or your company about to disembark on a dig ? Whether it’s to install new services, renovate land, or make way for some new landscaping, there is one important thing you must do first: locate utilities that may be buried in the ground.

Before you do any digging, you must have a professional company locate utilities such as sewer lines, electrical lines, water or plumbing lines, just to name a few. A failure to properly locate these lines is not only a hassle, it’s potentially dangerous, as well.

In order to better understand the necessity of locating utilities before you dig, read on to find out more about the dangers of unknown utilities and why it’s best to hire a professional NDT inspection when attempting to locate buried utility lines.

Dangers of Unknown Utilities

There are many dangers associated with unknown utilities; or rather, dangers associated with digging up land without knowing what (if any) utilities are buried there--and where those utilities are located.

For one, if you or your crew accidentally dig into electrical lines , you will be disrupting electrical services. The lines will need to be prepared, which could actually cost your company money depending on local ordinances and laws regarding buried utilities.

Another issue associated with not knowing the location of buried utilities is genuine danger. Depending on the type of line that is buried, you or your crew could be putting yourselves, as well as any people or homeowners in the vicinity, in harm’s way.

One-Call VS. NDT Inspection

There is a service known as " one-call " which is designed to help people and organizations locate utility lines. However, this one-call service is very limited and is likely not going to be genuinely thorough or helpful in most cases. One-call services only locate a public utility. Anything other than a public utility will not be marked for future reference.

For instance, one-call does not cover locating sewer lines or storm sewers; electrical lines to exterior buildings, such as barns or an exterior garage; gas lines to certain types of gas-run features, such as a fire pit or a heated pool. This lack of utility marketing is even more prominent when it comes to commercial properties, as one-call services won’t even locate electrical wiring in spaces like parking lots.

Thankfully, there is an option out there: private inspection services. The best type of private inspection service to call before digging is an NDT inspection service. An NDT inspection, or a non-destructive testing inspection , can locate far more utilities than public utilities.

NDT inspection services can locate a vast array of utilities, and they can do these inspections in just about any type of designated space. This includes commercial, residential, industrial, and even service specific spaces such as gas stations or industrial spaces.

Remember: inspections are essential before you do any digging, no matter what the project or circumstances. Running into unknown utilities is not only going to cost you money in the long run, it’s potentially dangerous as well. Hiring an NDT inspection service before you dig is the best option to ensure that things run smoothly. If you are searching for NDT inspection services, Steel City NDT is the company to contact .

Common Types of Non-Destructive Testing Services

Fri, 11 Mar 2022 20:26:02 GMT

Non-destructive testing is critical in many different industries. The nature of non-destructive testing, or non-destructive examination services, makes it a viable solution that has become increasingly popular in recent years due to the importance of effective, non-disruptive testing for industries and their assets. The following guide will help you learn more about the most common types of non-destructive testing services.

What Are Non-Destructive Testing Services?

First, it's important to understand the basic nature of non-destructive testing services. A non-destructive testing service allows for equipment to be inspected or examined without it being shut down or physically entered.

This allows for the operation of the equipment to continue without significantly interrupting its work time, and thus interrupting the productivity of the equipment.

In industries where productivity is critical not only to profits but to the continued creation of assets, non-destructive examination services are extremely beneficial and important. Even a single day of non-operation can mean the difference between a productive and non-productive output, which is where non-destructive examinations come into play.

Common Types of Non-Destructive Testing

The following are some of the most common types of non-destructive testing that are utilized today, along with the types of issues that they can typically spot:

Ultrasonic

Ultrasonic testing involves the usage of ultrasonic waves to help defect issues and characteristics of asset material. Ultrasonic waves can help determine characteristics like thickness and elasticity, as well as spot issues like cracking and the wearing down of material.

Penetrant

Penetrant testing is designed to help spot any issues in smooth, non-porous surfaces. The most common usage for this technique is to find issues with forging, welding and casting elements, such as any existing leaks or cracks. This technique requires applying penetrant to the asset and then determining whether any penetrant remains after its removal, indicating an issue.

Visual

Visual testing is a visual inspection by trained technicians who are trained to spot visual issues with equipment and assets. Visual inspections include niche inspections, such as a certified welding inspection , which is done by a technician trained in that niche.

Magnetic Particle

Magnetic particle inspections allow for anomalies to be detected in materials like nickel, cobalt and iron. This technique uses a magnetized material that is applied to the equipment or asset that is being tested, which will help determine any potential flaws.

Which Type of Testing Is Best?

The type of non-destructive testing utilized for any particular piece of equipment or particular asset will depend on the nature of the equipment as well as its materials. For example, visual inspections can be done on just about any type of equipment. However, magnetic particle inspections are suited to equipment or assets which will respond to the magnetized material required to perform this type of inspection.

If you aren’t certain which type of inspection is best for your needs, feel free to reach out to Steel City NDT . We’d be happy to help you determine which testing method - or if necessary, multiple testing methods - are best suited to your situation.

Why Choose Non-Destructive Testing Services?

Fri, 11 Feb 2022 16:27:10 GMT

Non-destructive testing services are an integral part of many different industries. Non-destructive testing , also known as non-destructive examination, is essential for the livelihood of businesses that rely on regular inspections to ensure that equipment is safe and productive. If you want to know more about why non-destructive testing is so essential, consider the following guide that will help you learn more about why this testing technique is important.

Non-Destructive Testing

First: what is non-destructive testing? Non-destructive testing techniques are examination / testing techniques which are designed to not be disruptive to the operation of equipment and assets. Non-destructive testing is essentially meant to allow companies the ability to avoid shutting down equipment for inspections. This has several benefits, which will be explored in the next section.

There are many different types of non-destructive testing techniques. These techniques include, but are not limited to:

Visual inspections , or inspections which seek to find visual flaws or issues
Ultrasonic testing , or testing which uses ultrasonic waves to find issues and determine material characteristics
Penetrant testing , or testing which uses penetrants to find leaks, cracks and similar issues
Magnetic particle testing , or testing which uses magnetized material to find issues in iron, nickel and other magnetic materials

Benefits of Non-Destructive Testing and Why It’s Used

There are many benefits to using non-destructive testing, along with many reasons why companies choose this type of testing over others. Let’s take a closer look at these benefits and why they are beneficial to various industries.

Non-Destructive Testing is Non-Disruptive

Many types of equipment and asset testing are disruptive to the production process. They require equipment to be shut down entirely, because the equipment must be explored physically, whether that involves a testing technician entering equipment or taking it apart to search for potential issues.

Non-destructive testing, on the other hand, does not require equipment to be shut down. It can be safely done without disrupting the production.

This benefit is twofold: it allows for the productivity of the equipment to continue, which will not impact the output of the industry; this, in turn, allows for increased profits and decreased profit loss that would otherwise occur with a more disrupted examination.

Non-Destructive Examination Techniques are Tailored to the Equipment

While visual inspections are generally universal, the other types of non-destructive testing techniques are specifically tailored to different types of equipment. For instance, magnetic particle testing is designed for equipment that uses magnetic materials like iron and cobalt.

This specialization allows for a much more effective method of testing, as the techniques are more likely to detect flaws or potential issues when compared to generic disruptive forms of testing. In turn, this means that issues are much more likely to be spotted and fixed before they become more serious. This is not only beneficial because it avoids shut-downs due to equipment breaking down unexpectedly, but it’s beneficial for safety reasons as well.

Ground Penetrating Radar Utility Mapping

Thu, 09 Dec 2021 17:25:26 GMT

One of the major uses of Ground Penetrating Radar is to locate most utility lines, big or small. This is not only to find them in case of repairs, but also for construction site digs so that they are mapped out and easily avoided to avoid unnecessary damage which, in turn, avoids unnecessary costs.

Utilities GPR Can Locate

Communications and Data Lines – Whether in a residential or commercial setting, it is highly recommended that these utilities are located to prevent unnecessary downtime and unnecessary costs. Communication and Data lines include, but are not limited to, phone lines, high speed internet lines, cable television lines, and the like.

Gas, Water, and Sanitary Lines – Even more important than communication and data lines, all sorts of gas, water, and sanitary lines are able to be located with the correct equipment. Successful mapping of these lines will ensure that digs can be made in the correct areas to make necessary repairs, or so that these lines can be avoided altogether to avoid damage. As you know, if one of these lines is hit during a dig, thousands of dollars in repairs could be the result.

GPS Mapping of Utilities Located

Once said utilities are located underground using GPR equipment, a GPS unit is able to be attached to the unit itself. Using the most groundbreaking software, it is possible to map out the utilities. Once these utilities are mapped out, not only can specific coordinates be provided, but a mapping system compatible with Google maps is also possible.

Cause & Effect Corrosion in Amusement Rides

Thu, 09 Dec 2021 17:22:29 GMT

Corrosion on carnival/amusement rides is not only common, but it also can cause catastrophic failures as most recently seen in the Ohio State Fair accident which resulted in several injuries and one casualty. Not only is Steel City NDT LLC capable of testing for corrosion, but we are also able to tell you the extent of the corrosion.

Causes of Corrosion on Amusement Rides

Corrosion is an electrochemical reaction that appears in a number of different forms
A major cause of corrosion in amusement rides is due to acidic substances, most commonly rain, that creates rust over time
Rust is the result of corroding steel, which takes place when the iron particles are exposed to oxygen and moisture (even humidity)
When iron particles are exposed to oxygen, they become oxidized creating a cathodic area
A corrosion pit is then formed where the affected iron particles were, and where they are now is called the corrosion product, or rust

Effects of Corrosion on Amusement Rides

A decrease of tensile strength is a key effect of corrosion. The affected areas become thinned out due to corrosion, thus reducing the member’s maximum load threshold
A member containing pitting corrosion is known to have a 2.5 times greater maximum load carrying capacity reduction
A wider, larger member is said to have a lower stress threshold for crack initiation than that of a much smaller, thinner member when exposed to corrosion
When pitting corrosion is involved, there is a greater negative impact on buckling strength

How Steel City NDT LLC Can Help

With the most recent accident at the Ohio State Fair, it was known that the specific ride which failed only underwent a visual examination. Not only this, but there are exponentially fewer inspectors than there are amusement rides in Ohio alone. Think about this from a Nationwide standpoint and you can see the problem immediately.

At Steel City NDT LLC, we offer a wide variety of inspection methods which can assist in not only locating corrosion, but determine the extent of corrosion within a majority of the members. Methods including, but not limited to, Ultrasonic Testing, Dye Penetrant Testing, and Magnetic Particle Testing will show anything happening beneath the surface (such as corrosion that cannot be seen with the naked eye). Had the ride at the Ohio State Fair been inspected with any of these methods, the failure could have been avoided altogether. Please contact us if a new or existing ride has not undergone an inspection within the past year.

The Basics of Non Destructive Testing Part 1

Thu, 09 Dec 2021 17:16:48 GMT

Non-destructive testing methods test mechanical and other properties without permanently altering the subject, which saves time and money in product evaluation.

There are many companies that sell non-destructive machines to test material properties but they rarely explain how their methods work. Eng-Tips Forums member “afronova” posted the question, “Are there any good sites that inform about destructive and non-destructive material testing techniques?”

Well, afronova, there is now.

And so begins a three-part series on nine methods of non-destructive material testing. In part one, we discuss radiographic testing, ultrasonic testing and magnetic particle inspection.

RT – Radiographic Testing

Radiographic testing is often used to inspect assembled components and to find flaws in complex structures. It uses short wavelength electromagnetic radiation in the form of high-energy photons to penetrate materials and inspect for hidden flaws. Neutron radiographic testing uses neutrons in the place of photons.

Neutron radiation can pass easily through lead or steel but is stopped by plastics, water and oils. When radiation directed through the material hits a defect, it scatters. Variations in the radiation exiting the opposite side of the material thus allow quality professionals to identify the location of defects as well as determine the thickness and composition of the material.

Radiographic testing of a welded joint

UT – Ultrasonic Testing

Ultrasonic testing is used to detect defects in materials of any shape or type so long as they have smooth surfaces. Ultrasonic testing uses a transducer connected to a diagnostic machine to send vibrations/sound waves through a material. The apparatus is passed over the object being inspected. This often requires the use of a couplant (like oil or water) to connect the transducer and the object, which decreases inaccuracies and false readings in the results.

There are two methods of receiving the signal. First is ‘reflectio n’, where the transducer can both send and receive the signal. The other is ‘attenuation’, where the transmitter sends ultrasound through one surface and a separate receiver detects the amount that reaches the other side through the medium. Any decrease in the sound detected is caused by defects.

MPI – Magnetic Particle Inspection

Magnetic pa rticle inspection is commonly used outdoors and at remote locations for detecting surface and subsurface defects. It is based on the concept of magnetic flux leakage. Magnetic flux leakage occurs when an additional north and south pole are created by a crack in a magnet. At the crack, the magnetic field bulges to form a ‘leakage’.

Iron particles concentrated along magnetic field lines

In magnetic particle inspection, a part is magnetized either directly or indirectly. Direct magnetization occurs when an electric current is passed through the test object and a magnetic field forms in the material. Indirect magnetization does not involve a current applied to the material but occurs when a magnetic field is applied from an outside source.

Since iron particles concentrate along magnetic field lines, when they are applied to the magnetized part they will cluster around a leakage.

The above three methods have different uses and require different amounts of training to complete but all will leave your part just as you found it.

In part two we discuss dye penetrant inspection, eddy current testing and thermographic inspection. In part three we discuss leak testing, guided wave testing and visual testing.

Ground Penetrating Radar The Unique Applications

Thu, 09 Dec 2021 17:05:02 GMT

While The Most Ideal Application is Locating Voids and Utilities, GPR Goes Above and Beyond

When used in unison with the standard Ground Penetrating Radar equipment, equipment such as leak detectors, electromagnetic induction, and the like allow technicians to discover leaking pipes, trace and map utility lines with GPS, assist in archaeological digs, assess changes in the environment (soil contamination), and assist law enforcement without destroying evidence, among many others.

Archaeology

When Ground Penetrating Radar (GPR) is used with Electromagnetic Induction, technicians are able to assist archaeologists with digs. Using non-invasive techniques, historic sites can be ‘uncovered’ simply by utilizing these imaging systems. The crucial part of all of this is that these historic sites remain underground and protected.

Most recently, scientists, with the assistance of GPR technicians, were able to discover a holocaust escape tunnel without destroying or interrupting it.

Forensics

Again, with the key part of Ground Penetrating Radar being that it is non-invasive, technicians are easily able to assist law enforcement with investigations. Since non-invasive techniques are utilized, evidence will not be at risk for contamination or destruction. Buried weapon caches, evidence, or even clandestine burials are among the applications that technicians are able to properly locate and identify.

A great story recently came out of Vietnam where individuals are utilizing GPR to locate and return the remains of Vets missing in action from years ago.

Mars

Yes, Mars! Aboard NASA’s Mars Reconnaissance Orbiter, a Ground Penetrating Radar system was utilized called the Shallow Subsurface Radar. This system was able to ping toward Mars more than 700 times per second. This system allowed scientists to see beneath the surface of Mars revealing that it had gone through an extreme ice age that would have put Earth’s ice age to shame. This system also revealed to the scientists that, after creating a 2d map of the subsurface, there is a lot of H2O and CO2 trapped.

In summary, it is clearly becoming more and more obvious that these Ground Penetrating Radar systems are becoming more and more important in the world of science, investigations, and even environmental monitoring. This is yet another nondestructive testing method that can not only teach us more, but do so noninvasively and safely.

Ultrasonic Testing: A Brief Overview

Thu, 09 Dec 2021 17:01:29 GMT

Ultrasonic Testing, or UT, is one of the most utilized and helpful Nondestructive Testing methods used. Not only can a certified inspector identify thicknesses of various metals, but they are also able to identify cracks, as well as their length and depth. Ultrasonic Testing is also widely used due to its high sensitivity abilities which allows to identify even the smallest of cracks. This method is also highly preferred due to the fact that technicians can run a full investigation while only needing to access one side of the test piece.

When did it all begin?

Ultrasonic Testing, or UT, began as early as the 1940’s, but it’s initial origins can be dated back to the early 1900’s. The first patent related to Ultrasonic Testing was issued in 1942 which was titled “Flaw Detecting Device and Measuring Instrument.” This patent was specifically issued due to this new device’s ability to investigate a test piece without destroying or compromising it. This was the first piece of equipment created which allowed for the detection and identification of subsurface flaws.

How does it work?

Ultrasonic Testing works by utilizing a piezoelectric crystal ‘transducer’ which induces periodic electrical pulses of ultrasonic frequency into the test piece. A jelly like substance, also known as couplant, is applied to both the transducer as well as the test piece. This allows for separation between the test piece and the transducer. The two common types of ultrasonic testing are known as reflection, or pulse-echo, and attenuation, or through-transmission. Their names are quite self-explanatory. When the reflection method is used, the transducer both sends and receives the sound waves from one side of the test piece. When the attenuation method is used, one transducer is used to send the sound waves and one (typically on the other side of the test piece) is used to receive them.

Cause & Effect Corrosion in Piping

Thu, 09 Dec 2021 16:58:24 GMT

Corrosion in piping is not only common, but it also can cause catastrophic failures in industrial, commercial, and residential settings. Not only is Steel City NDT LLC capable of testing for corrosion, but we are also able to tell you the extent of the corrosion.

Causes of Corrosion

pH of the medium contained within the piping system
Temperature of the medium – The hotter the water, the more pronounced the corrosion
Velocity of the medium – Not only can excessive velocity cause corrosion, but sudden changes in direction due to elbows or turns can also do the same
Chemical make up – If referring to a water piping system, things like excessive calcium can cause buildup and eventually corrosion
Oxygen content – Oxygen is another thing that corrodes and degrades metals by converting the metal to rust

Effects of Corrosion

Leaks – On average, about 25% of steel pipes will have a leaking connection within it’s first 5 years of use
Drop in pressure – Even the slightest corrosion causes an irregular inner surface profile which causes unacceptable drops in pressure
Air contamination – When compressed air passes through a rusted or corroded pipe, it becomes contaminated with hydrogen ions and rust particles
Wasted energy – When a pipe becomes choked off by rust buildup, piping systems will consume extra power to overcome this friction

Ground Penetrating Radar is the Key to Concrete Cutting Safety

Thu, 09 Dec 2021 16:55:07 GMT

Many construction outfits are coming round to the notion that concrete scanning services are vital for job safety. Whether it’s retrofitting buildings to make them earthquake-proof or ADA-compliant, or remodeling existing structures to add capacity, it is essential to know exactly how to avoid hazards that may be contained within concrete. More and more they are turning to ground-penetrating radar (GPR) scanning to know exactly where to cut and drill to reach vital building components and avoid necessary structural supports and conduit lines.

Move to improve safety in remodeling projects

Penhall Technologies is a division of California-based Penhall Company, which offers concrete cutting, coring, demolition, and repair services. Penhall Technologies specializes in GPR scanning services and has been using GPR to scan for concrete hazards in the U.S. since 2001 and in Canada before that. With a safety-driven mission and culture, Penhall considers GPR the most reliable, non-destructive way to locate targets and hazards within concrete structures prior to cutting or coring.

The company has 38 locations in 18 states and Canada, and operates across North America. They see a variety of regional building trends that affect the need for concrete scanning. In California and other parts of the West Coast, the company does a lot of scanning work for floor and wall retrofit core placement while retrofitting hospitals and universities for earthquakes. In Hawaii, their projects include beachfront property remodeling; rather than doing a full building demolition, builders strip the building down and use the concrete base to piece together an entirely new structure – one that is ADA-compliant. In addition, they scan for rebar in existing structures in cities with older buildings, for example San Francisco or Washington, DC.

“We’ve seen an increase in column reinforcement projects, where people want to add extra levels to a stadium, parking structure, or airport,” said Penhall Technologies President Simon James. “In the past they may have had to demo the entire structure and start over, but now because the engineer can avoid hazards within the concrete, they’re able to actually calculate how much weight that column can bear with extra reinforcement.”

James explains that until about 15 years ago, workers going in “blind” while cutting into existing structures often risked hitting live conduit. “Now many industry experts recognize that cutting into these hazard types can be devastating if people do not scan first. GPR technology makes the project far safer and I consider its use to be a real game-changer.” According to Penhall, structural radar imaging is a service that quickly pays for itself many times over.

Penhall has a zero accident safety culture – no accidents are acceptable. The company has established a set of safety rules, practices, and behaviors – before they even touch the equipment they are thinking safety. The process begins with site surveying, during which the GPR technician leaves the equipment in the car before the job. He has a notepad and meets with the customer on site. They discuss exactly what the customer wants to achieve. He walks around and writes down every hazard. This pre-task planning includes looking for any structural signs that may signal a potential problem. For example, if there is a horizontal beam, there may be conduit along the floor. The scanners are also looking for other trades that may be doing something unsafe near the concrete cutting area and would try to eliminate the danger.

James likens the process to the one used by detectives. “We ask them to talk to the customer and be aware of the environment, the floor, and other utility lines. They look in advance to see if there is post tension cabling, and note the gauge of the rebar – before they even get their equipment out. They can avoid a major disaster by taking these 10 to 15 minutes to scope out the job.”

They also encourage all scanners to share anything new or challenging and to contact another scanner “live” to get a second opinion, especially when as-built drawings do not match GPR data – a common issue. They have also gone directly to GPR equipment supplier GSSI when faced with unusual situations to get advice on data interpretation. The company holds internal debriefings as well as debriefings with their customer’s management team when necessary.

Getting beneath the surface with GPR

Penhall uses a variety of equipment for scanning. A large percentage of their projects are conducted using a handheld device that combines a screen and antenna in one unit. The equipment is small and lightweight, which makes it easily maneuverable. This is extremely important for ergonomics, since scanners can be on the job for 8-10 hours a day.

When they need to get more granular with the depth or for unusual spaces, they use a larger GPR control unit, coupled with a variety of antennas for specific needs. Examples include a 1600 MHz general purpose concrete antenna, 400 MHz utility detection and mapping antenna, and the 2000 MHz Palm Antenna, a compact, integrated concrete antenna for tightly spaced areas like corners, against walls, and around obstructions. “The ability to interchange antennas is very valuable in more complicated scanning situations, especially for in-ground utility scanning,” said James.

Data analysis is key

In addition to the actual GPR concrete scanning step, data analysis is crucial in the quality of the work and the ability to safely and accurately pinpoint hazards. “It is as important to investigate the environment we are scanning and not only understand and assess a hazard, but also to be able to evaluate anomalies in the data for potential issues,” said Elizabeth Wilson, Penhall’s Director of Field Operations. “It takes knowledge, training, and experience to correctly interpret GPR data.”

This knowledge base is enhanced by Penhall’s training and mentoring philosophy. Two-person teams include a newer employee paired with a more experienced scanner. Expert scanners from California and Toronto hubs mentor staff, oversee their work, and check results.

The company believes it takes a special aptitude to understand the science behind GPR. To get employees with the right skills, they have begun to hire from outside the construction industry, for example those with either a geology or geophysics background. They also have a very active focus on hiring veterans, including those with either non-destructive testing (NDT) or bomb disposal training.

GPR allows safe remodeling of existing structures

One example of how GPR can be used to ensure job site safety was at a major hotel, where the owners wanted to build a shopping mall on top of a multi-story compound. One option was to demolish the compound, which itself posed a host of costs and safety issues. Instead, the owners decided to actually build on top of the building by reinforcing the entire structure. To reinforce the structure, they needed to drill into the basement and install reinforcing rebar and concrete columns. “Drilling into the basement can do more harm than good,” says James. “We were able to core and scan the area. An accurate understanding of where all the existing structural elements were in the basement enabled the contractor to avoid damaging the existing structure.”

Another example is a case of a mini skyscraper in Canada in which a contractor was renovating two floors of a building and installing disabled bathrooms. Safely installing all the necessary plumbing was a challenge because the floors contained a variety of structural elements running through them, including post tension cable. James explains that cutting post tension cable is not only dangerous for the structure and integrity of the building; it’s extremely dangerous for whoever cuts it. The cables are under incredibly high tension and can whiplash. There are no drawings that accurately lay out where the cables are, or even if the cables are in the concrete.

With the help of GPR, Penhall’s staff was able to locate the precise location of existing cables and enable the cutting crew to cut safely without causing any damage. The plumbers were then able to go to the job site and safely renovate the bathrooms.

At a major university stadium project in Arizona, contractors needed to reinforce columns and required a very accurate scan of the rebar placement. To ensure the structural integrity of the columns it was critical that they not cut into the rebar, and there was little to no room for error. Penhall analysts were able to sample scan columns with precision and allow the engineers and scanning team to build a project plan that would keep the project safe and moving forward.

Much like insurance, scanning brings a peace of mind for safety and cost savings that adds the real value. The bottom line is that cutting without scanning is a gamble. In addition, doing a small sample core or cut can help solidify data found in the scan. Taking a few minutes to test an area can prevent many potentially costly losses.

5 Practical Uses for Phased Array Antennas and Transducers

Thu, 09 Dec 2021 16:48:34 GMT

Phased Arrays Explained – the Really Short Version

So what is a phased array antenna? Any antenna, from the one in your smartphone to a thousand-foot diameter radio telescope, does just two things – it sends out or receives electromagnetic energy waves like radio, radar, TV, microwave, etc. Conventional antennas have a limited ability to direct their beams. That’s one reason many radar antennas rotate – to scan the entire sky they must physically move the beam.

A phased array antenna is different. It combines an array of small, fixed, individually controlled antennas that can direct the beam in multiple directions. It can also be used to improve reception.

So what’s a phased array transducer? Basically, it’s the ultrasonic version of a phased array antenna – it beams (and acquires) ultrasonic waves using a multiple transducer array.

Sit Back and Enjoy the Flight

Ever wonder how your airline keeps you hooked-up to the internet at 35,000 feet over the Atlantic? It may well be a phased array antenna.

Here’s the problem – as your jam-packed jetliner is winging its way to your next tiny hotel room, the satellites it’s using to stay connected to the internet are changing their relative positions. Conventional, fixed antennas can’t handle that kind of variation, but a phased array antenna is just the thing for ensuring clear reception – even over Greenland.

Non Destructive Inspection – of Course!

Phased array transducers are the core of advanced ultrasonic inspection. Used for inspecting welds and other high value structures, phased array ultrasonic systems directionally beam waves of ultrasonic energy through the inspection piece. This enables the phased array transducer to be mounted in one or a limited number of positions. In contrast, a conventional ultrasonic inspection system uses a transducer that must be manually moved over point on the test piece. This can lead to inaccuracies and even missed defects, especially if the inspection piece has a complex geometry.

Phased array transducers – suddenly a complicated inspection task is lot more simple and accurate.

Talk Radio? Yeah, We’ve Got That.

Ever wonder why AM radio stations frequently use multiple antennas to broadcast their signal? All those towers actually form one big phased array antenna. Why do it? One, it lets broadcasters direct their signal towards the geographic area that holds their prime listeners. Two, as the sun sets listener reception can be improved by switching phases and power levels in individual antennas.

Sports, politics, news, oldies – all brought to you by phased array antennas.

Admit it – You Want a Phased Array Radar for Your Car

That day may not be far off. Researchers at a major automotive company have demonstrated a small phased array radar designed to detect and identify pedestrians. With over 4,000 pedestrian fatalities every year in the US, it’s a problem in need of an effective solution.

Phased arrays provide a wide detection angle and rapid object acquisition. Hooked up to the vehicle’s control system, it can bring a car or truck to a hard stop before the driver even realizes that a pedestrian stepped into the danger zone.

The Ultimate Storm-Chaser

While not yet in widespread use, phased array radars may provide the ultimate early warning system for tornados and other dangerous weather. The Navy even built a mobile unit mounted to a tricked-out truck. Think of it as your ultimate pimp-my-ride for the storm-chasing crowd.

More than a science project, phased array weather radars promise faster, deeper scans of weather systems and that means earlier, more accurate weather warnings.

Why the World Would End Without Leak Detection Equipment

Thu, 09 Dec 2021 16:43:12 GMT

Leak detection equipment is a vital part of nondestructive testing. This type of testing is used to check for pressurization and other related concerns without doing any damage to the parts that are being tested. If it wasn’t for this kind of equipment being used on a regular basis, there are plenty of bad things that could happen. Here are just a few of the concerns that end users would have to deal with if they didn’t have the benefit of knowing that the systems and parts they need were thoroughly tested for leaks before they received them.

Parts and systems would explode

Without proper leak detection techniques and the equipment that makes them possible, the parts and systems that are created wouldn’t get tested properly. These parts and systems would then be in danger of exploding when they were put under pressure, which could cause serious problems. Not only could people be at risk, but the structures into which these systems were installed would also be at significant risk of damage due to explosions. Even the leaks themselves could cause high levels of harm.

People would be hurt or killed

Not only the explosions that could result, but the leaks that would occur, could be very dangerous to people working and living in the structure or in the immediate area. Depending on what was leaking, there could be toxic or dangerous substances spilling out of a part or a system that was designed to keep that substance contained. Over time, these kinds of substances could end up poisoning people through contact with the substance or through the inhalation of a chemical that is dangerous to human beings. The number of people injured or killed could be significant.

Costs would soar due to damage and replacement issues

With leaks and the potential for explosions to consider, there are serious costs that could occur without the use of equipment for leak detection. Not only would the parts and systems where the leaks occurred become damaged and have to be replaced, but the structures around them could also have problems. That’s an important issue to consider, and one of the reasons that the world would probably end if there wasn’t good equipment that could be used for leak detection. With the right kind of equipment, no one has to worry about the potential for significant cost and damage.

The world might not technically end without the equipment used for leak detection, but it could definitely be a more frightening and dangerous place to live in. Rather than take that kind of risk, it’s much better to have proper leak detection equipment in place, so everyone from the creators and testers of the parts and systems to the end users have less to worry about. The safety and peace of mind that come with proper equipment for the detection of leaks goes a very long way toward keeping nondestructive testing methods up to date and successful.

Welding Wonders: 4 Fun Facts About Magnetic Particle Inspection

Thu, 09 Dec 2021 16:39:30 GMT

Everyone loses from low-quality manufacturing, which is why welders and metal manufacturers have developed magnetic particle inspection or MPI. Designed to detect cracks and flaws, MPI is one of the most popular quality assurance methods in the metals industry. If you work or take an interest in metals manufacturing, you should know that MPI:

Saves Lives

MPI involves sending magnetic field metal structures. If there are any weaknesses on or within the metal’s surface, they will disrupt the magnetic field, causing iron particles to gather in those areas. Welders can thus detect and fix the damage that is too small for the eye to see. Such damage can quickly compromise the metal in high-stress situations, which can be life-threatening when it occurs on cars, planes, military equipment, and other devices. Thanks to MPI, however, manufacturers can fix or scrap weak metal before it goes into service. This likely saves thousands of lives all over the world.

Relies On UV Rays

Though we often hear about it as an environmental and public health threat, UV light is a metal inspector’s best friend. Inspectors have to detect fluorescent particles during MPI, but such particles are not visible in white light. When exposed to UV rays, these particles begin to glow, allowing inspectors to identify them with ease. UV light is available in different intensities depending on the specific particles.

Prospective inspectors need not worry: there’s nothing dangerous about this task. MPI lights rely entirely on UV-A rays, which do not cause the eye and skin damage often associated with ultraviolet radiation.

Can’t Work Without Cleanliness

When inspectors perform MPI, cleanliness really is close to godliness. For all the sophisticated equipment and science, inspections cannot be performed correctly unless the product being inspected is pristine. It is particularly important to remove paint, grease, and oil, as these substances trap ferrous particles and prevent them from moving to weak parts of the metal. This produces false positives, causing welders and manufacturers to use metals that are not safe. MPI experts are thus urging their colleagues to better clean the metal prior to inspection.

Is On The Move

MPI is currently the most common form of metal surface testing in the United States and Europe and has been so for more than half a century. As other forms of metal testing are being developed, however, the popularity of MPI in the West has begun to decline. At the same time, the use of MPI is growing in India, China, and other emerging economies, where it provides a convenient and inexpensive way to test metal. Those who specialize in MPI and companies that make the technology will thus have increasing opportunities for work and consulting in middle-income countries.

4 Common Misconceptions About Certified Welding Inspectors

Thu, 09 Dec 2021 16:33:33 GMT

For such an important profession, welding inspection is not well understood. Inspectors save thousands of lives and billions of dollars, yet many companies do not know how to use their skills properly. If you plan to become a certified welding inspector or work with one, don’t make the mistake of thinking that they:

1. Can Judge By Sight

Many underestimate the complexity of welding inspection, assuming that inspectors can find flaws just by looking at the metals. In fact, most metal flaws are far too subtle for the human eye to detect. Inspectors must instead rely on:

Magnetic Particle Testing, or the use of magnetic fields to find discontinuities in the metal.
Ultrasonic Testing, which involves detecting flaws with acoustics.
Other Non-Destructive Methods, including testing with liquid penetrants, radiation, and infrared technology.

Failing to understand the complexity of welding inspection is as harmful for manufacturers as it is for prospective inspectors. Many companies underestimate the task, don’t vet their inspectors properly, and end up with sub-par inspections.

2. Are Lone Wolves

Besides underestimating the complexity of inspection, many companies don’t realize that inspectors cannot stand alone. Testing is only as accurate as the conditions allow it to be, and even the most skilled inspector cannot test properly if the company doesn’t take proper precautions. Cleanliness, for example, is necessary for an accurate test; if the metal is greasy or oily, it will trap magnetic particles, undermining that form of testing. Manufacturers must thus keep their metal products as clean as possible and obey all of their inspector’s other instructions.

3. Can Switch From Job To Job

Not only is welding inspection a highly skilled profession, but the specific skills needed vary from company to company. Many companies create their own tests to certify welders and welding inspectors, which often differ significantly from the standard American Welding Society ones. This can often make it difficult for inspectors to switch to other companies if they don’t like their current jobs. At the same time, it means that certified welding inspectors become invaluable to companies once they are hired, giving them substantial bargaining power. In any dispute, a company is far more likely to accommodate its current inspector than it is to undertake the cost of hiring and training a new one.

4. Only Need Technical Skills

Although inspection is a highly technical job, communication is every bit as important to an inspector’s work. Inspectors must explain to welders and the broader company what flaws they detect, how to fix them, and how to avoid similar problems in the future. This means breaking complex scientific and engineering terms down into language that the uninitiated can understand. It takes great rhetorical skill to do this effectively.

Steel City NDT provides high-quality inspections on all types of metal. We carefully vet each certified welding inspector we hire, making sure everyone has the skills and experience to do the job correctly. For more information, visit our website today.

6 Myths About Hydrostatic Testing

Thu, 09 Dec 2021 16:27:09 GMT

Hydrostatic testing is a very important way to ensure that pipelines and other system parts are safe before they are installed. However, there are a lot of myths about this type of testing, and those myths can cause structural problems and put people at risk. Here are six common myths about hydrostatic testing.

During hydrostatic testing, you don’t have to remove gas tubes

Gas tubes should always be removed when doing any kind of testing. Leaving them where they can become damaged is not a good idea. It costs money to fix them, and if they become damaged and that damage isn’t noticed, they can end up being a serious risk to life and limb when the pipes or system finally goes live. By taking the tubes out during hydrostatic testing, you protect the tubes and other components and parts and reduce the risk of future problems.

You can’t test the integrity of a pipeline without hydrostatic testing

There are a lot of different ways to test the integrity of a pipeline, so you don’t have to use hydrostatic testing. It’s one option, and it’s one of the best options, but it’s not an official requirement. Other choices can be considered if there’s a reason the person doing the test would prefer to use a different kind of testing method.

If it passes the hydrostatic test, a visual inspection isn’t necessary

A visual inspection is always necessary. Passing the hydrostatic testing is important, but there should be more than one test or inspection conducted to make sure the welds are right, the pipes are holding, and all the components of the system are in full working order. A visual inspection can uncover things that other inspections or tests may have missed.

You don’t need to test at more than the system’s design pressure

By testing at 1.5 times the pressure the system is designed to hold, any problems can be located more easily. If something is going to fail, you want it to fail during the test, not during use. Using a higher pressure during the test can help ensure that any failures happen before the components are put into actual use.

It isn’t necessary to have all vents open before a test

Opening all the vents removes all the air from the pipes. The air needs to be able to escape fully before the test, so don’t leave vents closed. All the air might get out, but you’ll put a strain on the system that isn’t necessary, and that can be avoided.

You can weld after the test is performed

Welding should be done before the test is carried out, as it may not be safe to weld afterward. Making sure all the welding and other hot work is performed first can provide hydrostatic testing that is much more accurate. Finish any and all welding on the pipe system, and then perform your hydrostatic testing.

The Cool But Untold History of Ground Penetrating Radar

No one needs to tell you that before you raise a structure, whether it’s a skyscraper or an airplane hangar or a grocery store, you’ve got to know a whole heck of a lot about the ground you’re building it on. Non-destructive testing(NDT) has a solid reputation in the construction field because it allows workers to ascertain that a particular site is stable, firm and safe … or alternatively, not.

One such NDT technology is ground-penetrating radar. You may think the name says it all, but really, there’s a lot you might not know. Here’s a brief untold history of one of the most reliable technologies in the industry.

The Application Was Obvious

You might think that when Christian Hülsmeyer patented radar back in 1904, he might first have spent a lot of time pointing it at the sky. After all phrases such as “flying under the radar” make us assume this device is most often used to locate enemy airplanes (or submarines).

But actually, radar technologies – which use radio waves – were pretty quickly pointed at the ground. As early as 6 years after the patent, Gotthelf Leimbach and Heinrich Löwy patented the first radar technology to locate buried objects.

It’s Not Just for Construction

As it happens, archeologists have also found a wide range of applications for ground penetrating radar as well: Mayan houses and platforms, burial tombs, cellars and graves, and pit dwellings are all among the scientific discoveries made using this technology to make maps of what’s beneath the surface. The military also uses it for detecting underground dangers and to avoid tunnels, among other things.

Not All Ground Is Alike

Unfortunately, you can’t just point a device at the ground and go. Well, you can, but in many cases it works better than others. You probably already know that radar relies on conductivity: it uses a wave, and that means it needs something to travel through. Soil, clay and moist materials don’t present much of a problem, and you can get a clear map.

On the other hand, dry or very sandy soils don’t conduct well. Ditto concrete, granite, cement, or other large, heavy masses. Also, ground penetrating radar works best at ranges between 20 cm to 5 m below ground, which means mapping the secrets of the Earth’s core is best left to other means.

It’s a Relatively New Construction Tool

The applications of ground penetrating radar to construction are so obvious, you might think it has always been used for this purpose, but not so. It wasn’t until 1985 or so that radar systems actually became affordable, and not until sometime in the 90s that comprehensive textbooks and knowledge bases made using them feasible.

Nowadays, ground penetrating radar is a wonderful tool in the NDT kit. Moreover, you don’t have to do it yourself. Instead, you can hire experts like Steel City, NDT, to do the job for you, making your job safer, faster and easier.
