What Is Nondestructive Testing?

Nondestructive testing (NDT) is a profession that combines quality assurance and materials science. Its purpose is to examine materials, components, or assemblies without destroying them. Technicians use test methods to find problems like cracks, voids, weld issues, and misassembled parts.
NDT is crucial because it helps ensure that products are safe and reliable. It controls manufacturing processes, reduces costs, and maintains product quality. Without NDT, there's a risk that parts might not work. This can lead to failures, causing airplane crashes, train derailments, pipeline explosions, nuclear reactor malfunctions, or ships sinking.

Industries that utilize NDT include:

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