https://www.bkneddy.com/eddy-current-testing-equipment/ect-for-automotive/ NDT Application in Automotive Industry: Eddy current testing technology has been widely used in the detection of metal components in the automotive The eddy current technology is usually used to detect engine blade cracks, bolts, cracks in the screw holes, multi-layer structure of the aircraft, landing gear, wheels and aluminum skin as the main NDT non destructive testing methods. And subsurface defects, and used to detect defects in the wing joint weld. In the detection, it can effectively suppress the shaking of the probe, and the material is uneven and cause interference signals. Metal magnetic memory testing technology can be used to diagnose the stress concentration of the above components or early damage.
