What is Non-Destructive Testing (NDT)? Definition, Methods, and Applications

NDT, or non-destructive testing, is essential in many industrial sectors

Non-destructive testing (NDT) is a set of methods and techniques that allow you to assess and verify the integrity of your materials or structures throughout their life without altering them. Performing NDT checking is essential to ensure the safety and robustness of your products or to quickly detect potential defects.

To successfully conduct a non-destructive inspection, it is crucial, depending on your industry needs, to choose the right method and tools. Radiography, ultrasonics, and magnetic particle testing – each NDT method will be more or less suited to guarantee a quality check.

With non-destructive inspection, many defects can be detected

What Are the Different Methods of Non-Destructive Testing?

What Potential Defects Are Sought in NDT?

Non-destructive testing helps identify three types of defects:

  • Non-compliance with specifications: Incorrect dimensional measurements, incorrect angles, incorrect surface condition, etc.

  • Internal defects: Porosities, blowholes, inclusions, non-penetrating cracks, thickness variations due to wear or corrosion, etc.

  • Surface defects: Cracks, holes, fissures, pits, etc.

In addition to detecting these defects, a non-destructive test will characterise and precisely size them to ensure the best compliance.
