Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component surface & subsurface without causing damage or effect to their future performance or properties. Non-destructive testing is used to detect abnormalities in physical, chemical or electrical characteristics.

NDT provides an edge over conventional methods as it is a fast, cheap and easy process. In 1930s, non destructive testing, where it had been heard of at all, was generally considered an evil.
