When you call Anode NDT, you receive experienced level II, CGSB/SNT-certified technicians. These highly trained and completely certified technicians guarantee every piece of equipment is tested to the best of our abilities.

How it Works

As a non-destructive testing technique, radiographic testing (RT) analyzes the structural integrity of a material by directing radiation through its surface. This locates any subsurface imperfections, including flaws in the weld or the material itself.

Once the radiation has been directed through the material, the equipment generates a 2-D image on radiographic film. This provides a complete internal and external structure of the weld. From there, a non-destructive-testing (NDT) professional interprets the results. Our clients receive the technican’s interpretation according to the code or standard for which the inspection is being performed. They’ll also receive any corrective action that needs to take place in order for the specimen to adhere to code.

Radiographic testing begins with thorough safety checks on equipment. Once complete, we clear the area of any non-nuclear energy workers.

We place a radioactive device on one side of the material and a radiographic film on the other.

We use the radiation to penetrate the part. This penetration leaves a shadowgraph on the film that shows the structural integrity of the material in 2D.

Our radiographic testing technicians interpret the results and inform the client of any potential defects.

We deliver a full report based on our non-destructive testing findings.

NDT Film Digitizing and Archiving

At Anode NDT, we prioritize the accessibility of your data. The results of our radiographic testing services are presented to you digitally, eliminating the need to store bulky film or purchasing equipment to view it on.

We also have the necessary equipment to digitize NDT film for storage on mobile storage devices. Our technicians can complete this for current and past projects, provided you have the traditional film.

While digitizing your NDT test results makes it more accessible, we know it can make it harder to keep track of. We keep extensive records of your NDT testing. At Anode NDT, we store the original film at our head office. The digital copy remains in our database in case you require another copy.

Radiographic Testing Identifies Defects Such As…

Lack of Fusion

Radiographic testing identifies where the material was incompletely fused. As a lack of fusion results in a disconnect between the metal and the filler, these defects decrease the structural integrity of the material. Welds that aren’t completely fused present both a danger and cost-risk, causing companies to lose time, money, and possibly more.

Incomplete welds can be difficult to locate without radiographic or ultrasonic testing. Because they’re planar defects – it exists along a single plane or two-dimensionally – lack of fusion can go undetected in other inspection methods.

Incomplete Penetration

Radiographic testing also detects incomplete penetration. Incomplete penetration – poor adhesion of the weld to the parent material – occurs when the weld bead does not start at the roof of the weld groove. It can develop due to poor welding techniques, improper weld design, or unsuitable weld conditions.
Incomplete penetration is a problematic defect as it allows a natural stress riser, which can form cracks. Radiographic testing can identify incomplete penetration, saving your time and money from costly disruptions to daily operations.

Undercuts

Undercuts in welding is the erosion of the base metal that occurs next to the weld. These undercuts, also known as internal or root undercuts, occur when the weld fails to fill in the grooved area. These defects are costly and can cause decreases in productivity and speed. 

Internal undercutting can be discovered through such non-destructive testing as radiographic or ultrasonic testing. Detecting these crater-like defects is vital to the efficiency of a pipeline and will prevent unnecessary, and costly, downtime.

Hollow Bead, Porosity & Pinholes

Radiographic testing catches porosity, also known as hollow bead or pinholes, in a material. Porosity occurs when gas pores are found in a weld bead. This defect is caused by the absorption and then solidification of nitrogen, oxygen, and hydrogen into the weld metal.

Without detection, hollow bead or porosity can cause leaks, problems with flow rate, draughts, and excessive turbulence. Determining that porosity and pinholes exist in a material is the first step in preventing interruptions to regular workflow.

Tungsten or Slag Inclusion

Both slag and tungsten inclusions are easily detected by radiographic testing. These defects are caused by a material – in this case, either slag or tungsten – becoming caught and embedded in the weld.

A certain amount of slag and tungsten inclusions are acceptable, as long as they remain within code standards. Should these inclusions exceed the acceptable amount, the material is considered to be at risk of cracking or fracturing.

Our capable team remains up-to-date on the codes to ensure all equipment we inspect is within this acceptable amount.

Burn Through or Icicles

Burn through and icicles are both detectable with radiographic testing. Both these types of defects are caused by excessive penetration during the welding process. Burn through occurs when the metal melts from the root of the weld, while icicles occur due to fused weld metal droplets that extend beyond the weld root.

Burn through, if left undetected, can result in catastrophic leaks and material failure. As burn throughs lower the structural integrity of the material, the detection of this defect is vital to a safe and productive environment.

Left unfound, icicles increase the stress concentration on the material. Excessive amounts of icicles, if present, can indicate that the material needs to be replaced in order to prevent downtime.

Internal Concavity

Internal concavity, or suck back, are welds that have contracted into the weld root during the cooling process. These defects are easily detectable through radiographic testing.

Internal concavity poses a danger as it reduces the strength of the weld. When present in materials on job sites, suck back can reduce productivity and result in needless and expensive downtime.

High-Low Misalignment

High-low misalignment occurs when there is a material misalignment during the welding process. Material misalignment can be found through radiographic testing, as a trained operator can interpret the defect.

High-low misalignment is considered one of the contributing factors to various failures in various pipelines, including pre-service hydrostatic test failure or subsequent service failures. Ensuring your pipeline is free of this defect is vital in maintaining an efficient and productive worksite.

Cracks

Radiographic testing definitively detects the existence of internal cracking in your material. Cracks form a number of different ways. These cracks may be present as a result of welding errors. They may also be a result of the pressure the material is under, corrosion, or other reasons. 

Cracks present a serious danger, as they can lead to leaks, breakages, and material failure. Understanding the types and severity of any cracks present in your equipment gives you the opportunity to avoid any catastrophic disaster or equipment failure.

Thinking Ahead: Radiographic Testing for Gas Plants

When not completed by qualified professionals, radiographic testing can lead to serious consequences. With years of experience with radiographic testing and other forms of non-destructive testing, we understand the need to remain in constant communication with our clients. 

Radiographic testing at a gas plant, for example, emits enough gamma rays to trigger fire eyes. These sensors will shut down the gas plant, resulting in unnecessary and costly downtime.

To avoid this, our technicians inform gas plant operators when we’ll be completing the testing and all necessary procedures involved. We temporarily bypass the appropriate safety measures to safely and efficiently complete the radiographic testing.

Maintaining this level of communication prevents any avoidable downtime or other costly consequences while creating the most efficient environment to complete our testing.
