What Is Nondestructive Testing?

Nondestructive testing (NDT) is a profession that blends quality assurance and materials science. NDT is used to inspect and evaluate materials, components, or assemblies without destroying their serviceability. Through a set of test methods, technicians identify cracks, voids, inclusions, and weld discontinuities, as well as identify misassembled subcomponents.

NDT is used to ensure product integrity and reliability, control manufacturing processes, lower production costs, and maintain a uniform quality level. Without it, the safety and reliability of components can be seriously jeopardized. This makes NDT crucial to help prevent catastrophic failures such as airplane and locomotive crashes, pipeline leaks and explosions, nuclear reactor failures, and ships sinking.

Industries that utilize NDT include:

  • Aerospace
  • Manufacturing
  • Energy (oil and gas, nuclear)
  • Chemical
  • Infrastructure (Bridges, Highways, Buildings)
  • Transportation (Automotive, Railways)
  • Maritime
  • Construction
