Abstract

Ferromagnetic materials such as steel have high magnetic permeability, and thus their skin depth is shallower than that of non-ferromagnetic materials. Therefore, inspection at low frequency is required to examine a thick steel plate using eddy current testing (ECT) [1], [2]. Previously, we have demonstrated, using an electromagnetic simulation in conjunction with the finite element method, that the slit defect in the backside of the steel plate can be detected when the excitation frequency is low enough [3]. In this study, we propose a system that detects slit defects in the backside of the steel plate using low-frequency-ECT (LF-ECT).
