Non-Destructive Testing (NDT) is a descriptive term used for the examination of materials and components in such a way that allows materials to be examined without changing or destroying their usefulness. NDT can be used to find, size and locate surface and subsurface flaws and defects.
NDT plays a crucial role in everyday life and is necessary to assure safety and reliability. Typical examples are found in pipelines, bridges, trains, power stations, refineries, infrastructures such as buildings and bridges, oil platforms, and aircraft which are all inspected using NDT.
