NDT testing is used to assess the integrity, quality, and reliability of materials and components without causing damage. It is commonly applied in industries such as aerospace, automotive, oil and gas, and construction to detect defects, measure material properties, and ensure structural soundness.

Different NDT Techniques
You may have heard about radiographic testing, ultrasonic testing, magnetic particle testing, liquid penetrant testing, and eddy current testing, but what do these techniques actually involve? Let’s dive into each method and how they are applied in industry inspections.
Radiographic Testing (RT)
Radiographic Testing (RT) uses X-rays or gamma rays to produce images of internal structures. This technique is highly effective for detecting internal flaws in welds, castings, and structural components. The images produced can reveal cracks, voids, foreign material, and other imperfections that might not be visible from the surface. At WHLabs, our advanced RT services utilize digital imaging techniques for quick and accurate results.
Ultrasonic Testing (UT)
Ultrasonic Testing (UT) employs high-frequency sound waves to detect surface and subsurface imperfections in materials. It is commonly used for inspecting metals, composites, and ceramics. The UT equipment emits a sound pulse into the material being tested, and when a discontinuity or defect is present, the sound wave reflects back to the transducer. This reflection is then analyzed to identify any flaws. Here at WHLabs, we use state-of-the-art ultrasonic equipment to ensure high precision in flaw detection.
Magnetic Particle Testing (MT)
Magnetic Particle Testing (MT) is ideal for detecting surface and slightly subsurface discontinuities in ferromagnetic materials. This is achieved by applying a magnetic field followed by dusting iron particles onto the surface to reveal any cracks or defects. This method is particularly sensitive to identifying defects that lie just under the surface and can be performed quickly. Our laboratory specializes in fast and thorough MT for various industrial applications.
Magnetic particle testing is an exceptionally useful technique because it can show you things that other methods might miss.
Liquid Penetrant Testing (PT)
Liquid Penetrant Testing (PT) involves applying a liquid with high surface wetting characteristics to detect surface-breaking defects in non-porous materials. The liquid penetrates into any surface openings or cracks through capillary action, allowing for accurate defect identification. The simplicity and effectiveness of this technique make it widely used across multiple industries. At WHLabs, we guarantee meticulous execution and accurate defect identification using PT.
Eddy Current Testing (ECT)
Eddy Current Testing (ECT) utilizes electromagnetic induction to detect flaws in conductive materials without requiring the removal of surface coatings. It is particularly useful for inspecting tubing, wires, and components where access is limited. The continuous advancement of technology has equipped us with cutting-edge eddy current devices to provide comprehensive inspections for our clients.
Each NDT method offers unique advantages and applications in detecting different types of flaws within various materials; their implementation requires expertise and precision to ensure reliable inspection results benefiting diverse industrial sectors.

Our facility employs the latest radiographic systems to deliver detailed visual records of these internal structures without exposing you to unnecessary risks. Whether identifying tiny cracks or pinhole defects within metals, our approach ensures nothing remains hidden from view.
Consider this: when an aircraft is set to soar through the skies with hundreds of lives on board, there’s no room for compromise in its structural integrity. X-ray or gamma-ray radiography provides detailed insights into the condition of critical components – a difference-maker between ensuring safe flights and potential catastrophic failures.
Acoustic Emission Testing (AET) is similar to having a highly sensitive microphone poised to pick up sounds generated from within materials. It monitors transient elastic waves released during material deformation or crack formation. This makes it effective in predicting potential failures in structures under stress, offering valuable insight into early warning signs that could prevent catastrophic accidents.
Imagine having a system that can detect the sound of trouble before it becomes a major problem – invaluable for ensuring the reliability of critical infrastructure or safeguarding the structural integrity of machinery and equipment used in industrial settings.
Lastly, Infrared and Thermal Testing (IRT) play a pivotal role in detecting thermal anomalies that reveal subsurface defects or variations in material properties. This technique is particularly useful for inspecting electrical systems, composites, and structures.
Just like how a doctor uses infrared imaging to reveal health issues beneath the skin without invasive procedures, IRT showcases vulnerabilities hiding beneath pristine exteriors. The ability to identify thermal anomalies before they escalate serves as an invaluable asset across multiple industries.
These primary materials testing technologies serve as formidable tools for peeling back the layers of an object or structure to reveal its true condition. Each method holds unique capabilities crucial for maintaining industry standards and ensuring the safety and reliability of critical infrastructures at all times.
New perspectives surface when detecting flaws and defects within various materials; it’s more than just about visualizing what’s beneath the surface.
Detection of Flaws and Defects
Nondestructive Testing is akin to detective work for materials, seeking out hidden problems that could lead to significant trouble if left unnoticed. At WHLabs, we understand how various flaws such as cracks, porosity, inclusions, and corrosion can weaken structures and components, posing risks to safety and reliability. By employing advanced NDT methodologies, we ensure the timely identification and precise characterization of these defects, helping to prevent structural failures before they occur.
Picture having the ability to unveil concealed cracks that could lead to devastating consequences if left unnoticed—thanks to ultrasonic testing, we can precisely do just that. This method is like having X-ray vision for materials, allowing us to pinpoint irregularities and vulnerabilities in complex geometries with remarkable accuracy.
Cracks
When it comes to detecting cracks, it’s not always as simple as it seems. Some cracks are visible on the surface, but others are hidden from plain sight. Using advanced tools and techniques like ultrasonic testing allows us to identify the tiniest of cracks that might go undetected with regular visual inspection. By revealing these hidden fractures, preventive measures can be taken to avoid potential failures.
Porosity and Inclusions
Porosity and inclusions within materials can create weak spots that compromise their strength. Through sophisticated NDT methods such as radiographic testing and eddy current testing, these imperfections can be detected even within denser metal structures. This helps identify areas where the material may be prone to failure under stress before it becomes an issue.
Corrosion
Corrosion silently attacks metals from within. With our high-tech corrosion mapping tools, large surfaces can be inspected quickly and accurately to determine the extent of corrosion damage. This enables us to implement targeted maintenance measures to mitigate further corrosion effects and extend the lifespan of critical components.
