Abstract

Abstract: When pulsed eddy current testing signal is used to reconstruct defect profile, the signal features of the same defect for different materials are different, and the reconstruction accuracy of defect profile is influenced by the material properties. In order to eliminate the influence of material properties on defect profile reconstruction, a defect profile reconstruction method based on invariance function is proposed. The two features that can characterize the same defect are utilized to construct the invariance function which can eliminate the influence of material properties. A nonlinear mapping model from testing signal to defect profile is established, and the defect profiles of different materials are reconstructed. The approach is utilized to reconstruct the defect profiles of different materials. The results indicate that the proposed approach can eliminate the influence of material properties effectively and reconstruct the defect accurately, and the performance of noise interference suppression of the method is high. It is an effective and feasible approach for defect reconstruction.
