Non Destructive Examination explained

 

Non-destructive examination (NDE), also known as non-destructive testing (NDT) and non-destructive inspection (NDI), is testing that does not destroy the test object. NDT is vital for the manufacture and maintenance of all types of components and structures. To detect different defects such as cracking and corrosion, there are different methods of testing available

It is very difficult to weld, forge or mould a solid object that has no risk of breaking in service, so testing in the course of manufacture and during service is essential. During the process of moulding a metal object, for example, the metal may shrink as it cools, and crack or introduce voids inside the structure.

Even the best welders (and welding machines) cannot produce 100% perfect welds, 100% of the time. Some typical weld defects that need to be found and repaired are lack of fusion of the weld to the metal and porous bubbles inside the weld, both of which could cause a structure to break or a pipeline to rupture.

During their service lives, many ride components need regular non-destructive tests to detect damage that may be difficult or expensive to find by everyday methods. For example:

  • Road wheel spindles

  • Axles

  • Pulley Shafts

  • Coupling Shafts
