Depending on the metal alloy, various types of non‐destructive inspection can be performed. Non‐destructive inspection can reveal discontinuities or additional cracking in the component. The most common types of NDE/NDT are Liquid Penetrant Testing (PT), Fluorescent Penetrant Inspection (FPI), Magnetic Particle Inspection (MPI), Acoustic Emission Testing (AE), Radiographic Testing (RT), and Ultrasonic Testing (UT). All these tests are used to detect surface cracks and discontinuities. Radiography is used mainly for internal examination. A photographic record of the results of non‐destructive inspection is a necessary part of record keeping in the investigation.
