摘要
为了有效利用电磁超声中的脉冲涡流信号,实现电磁超声、脉冲涡流检测方法对缺陷检测的优缺互补,提出了一种基于小波分析的脉冲涡流/电磁超声复合无损检测方法,并结合数值仿真和实验验证了所提方法的有效性。
To effectively utilize pulse eddy current signal parts in electromagnetic acoustic signals and complement the advantages of EMAT and PECT method in detection, a new hybrid NDT method of PECT/EMAT was proposed based on wavelet analysis. The effectiveness of the proposed method was verified by the numerical simulations and experiments.
