Non-Destructive Testing (NDT) / Non-Destructive Evaluation (NDE)

Inspect or measure without doing harm. Six core techniques cover everything from weld inspection to corrosion monitoring.

Non-Destructive Testing (NDT), also called Non-Destructive Evaluation (NDE), uses noninvasive techniques to determine the integrity of a material, component, or structure — or quantitatively measure some characteristic of an object. There are different NDT techniques used across industry, each ideal for different applications.
