Introduction to Non Destructive Testing
NDT [Nondestructive testing] is the procedure of inspecting, evaluating, or testing components, materials, or assemblies for differences, or discontinuities, in characteristics without causing damage to the serviceability of the system or the part. In simple words, when the test or inspection is finished the part can still be utilized. Contrary to NDT, other tests are destructive in nature and so they are performed on a restricted number of samples instead of carrying out on the components, materials, or assemblies that are essentially being put into service. The destructive tests are utilized to decide the materials’ physical properties like ductility, impact resistance, yield, ultimate tensile strength, fatigue strength, and fracture toughness, however, discontinuities and dissimilarities in material characteristics are more efficiently found by NDT. Various industries The modern-day nondestructive tests are utilized in fabrication, manufacturing, and in-service inspections to guar...
