摘要：In order to solve the problem of transverse crack detection, the method of dual probe cross-weld scanning is proposed. Based on the designed artificial specimen containing two groups of pre-located defects, through the comparison study of CIVA simulation and experimental testing of the specimen, the variation of the gain of different sizes of cracks was obtained with the optimal eccentricity angle of 40 similar to 50 degree. It was proved that this method has high detection sensitivity and high engineering application value.
