Non destructive testing is just that, it does not damage the article. It uses ultrasonic, magnetic and radiation to test for breaks or faults in what is being tested.
During their service lives, many industrial components need regular nondestructive tests to detect damage that may be difficult or expensive to find by everyday methods. For example:
aircraft skins need regular checking to detect cracks;
underground pipelines are subject to corrosion and stress corrosion cracking;
pipes in industrial plants may be subject to erosion and corrosion from the products they carry;
concrete structures may be weakened if the inner reinforcing steel is corroded;
pressure vessels may develop cracks in welds;
the wire ropes in suspension bridges are subject to weather, vibration, and high loads, so testing for broken wires and other damage is important.

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. Later it became a necessary evil. For a number of years now NDT has been a necessary aid. NDT has saved uncounted thousands of lives. Non destructive testing is not confined to crack detection. Other discontinuities include porosity, wall thinning from corrosion and many sorts of disbond.
STRC's dedicated NDT lab and certified technicians are capable to fulfill your entire industrial and structural requirement.
Because NDT does not permanently alter the article being inspected, it is a highly-valuable technique that can save both money and time. NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples.
STRC offers NDT technology that saves time & money.

Well, I am not really sure, but I think I have a pretty good idea. . .While watching a video from a college, there was a category under "non-destructive" testing. It explained that it was the process of testing a substance without harming whatever it may be. . .

Nondestructive testing (NDT), sometimes called nondestructive examination (NDE) or nondestructive inspection (NDI), is any method of materials testing whereby the material being tested is not damaged or destroyed. It is important in quality control as well as useful in research. It is also a key element in material inspection systems. Two reliable nondestructive testing solutions are ultrasonic testing (UT) and eddy current testing.

I am in the aircraft maintenance business, Non destructive testing NDT or Non destructive inspection NDI is used to inspect the aircraft or aircraft parts for cracks or signs of metal fatigue.
Methods are x-ray, dye penetrant, borescope, magnifying glass to name a couple.
