英文摘要	An ultrasonic vortex C-Scan technique has been proposed to inspect stainless steel resistance spot welding (RSW) joints. Wavelet decomposition method is applied to analyze the original A-Scan data. By combination of semisoft threshold constructor and ultrasonic power ratio arithmetic (UPRA), the effect of corona bond is eliminated effectively, and its boundary is abstracted legibly. The nugget diameter measurement error is reduced from 2, approximately, to 0.19 mm. The fitted curve, nugget diameter and tensile strength, can be used to predict maximum tensile strength of joints online without destructive experiment. Shrinkage voids flaws located in the middle of the nugget have little influence on tensile strength.
