This article presents a newly developed rotary scanning technique that combines eddy current and flux leakage test methods to inspect up to 3/8-in. flat carbon steel plate. The technique relies on a test probe that uses both methods to inspect the same location simultaneously. The eddy current method responds primarily to top surface signals, while the flux leakage method detects conditions on the top and bottom surfaces. By processing these signals and displaying them in a simultaneous dual-trace display, a determination can be made as to whether the signal originated from the top or back side of the floor plate.
