概要
Abstract This article outlines the development of structure adaptive nondestructive evaluation technology using eddy currents. A couple of eddy current testin g (ECT) systems are utilized. One performs high spatial resolution with multi-coil array probes, enabling us to identify crack positions by means of image pr ocessing. The other employs double excitation coil probes to detect relatively deep cracks from the scanning surface, showing detectability more than 5mm in d epth. Profiling/sizing cracks estimated from ECT signals suggest a computer-aided approach of quantitative nondestructive evaluation as efficient inspection.
