APPLICATIONS OF MOTORIZED ROTATIONAL RFEC PROBES IN THICK AND MULTILAYER STRUCTURE CRACK DETECTION

Crack detection in thick and multilayer structures has been a challenge to NDI/NDE societies. Remote field eddy current probes have shown features in deep penetration and high sensitivity. Motorizing the probes is an approach to improve the consistency of the signal received from the probe that enables on‐the‐spot signal processing and crack identification. It also minimizes human factor in crack detection. The newly developed NDI/NDE system provides higher reliability, repeatability, and confidence in crack detection in thick and multilayer structures.
