Nondestructive testing (NDT) is a set of analysis techniques used to evaluate the properties of a material, component or system without causing damage :
- in process (presence of defects during manufacturing)
- in use (appearance of defects over time or after shock)
Nondestructive testing is a major asset in terms of quality control which enables contact-less search for defects and determines the properties of a material such as position, shape, size, ...
These properties are widely used in automotive industry (engine control unit), oil industry (pipelines, tubes, bars, solders, tanks), shipbuilding industry, aeronautics (wings, engine parts, landing gear, etc.), aerospace and defense, energy industry (reactors, boilers, piping, turbines, etc.), railway manufacturing and maintenance, especially for security components (axles, wheels) and more.
