| Due to the influence of various factors, welding defects such as cracks, shrinkage cavities and incomplete fusion are prone to occur in the nugget area during resistance spot welding process. The quality of spot welding directly affects the service life of welding components, so the defect detection and quality evaluation of spot welding are very important. In this paper, the principle of resistance spot welding is generalized, and the latest research results and applications of quality detection technology for resistance spot welding are summarized. Also, the monitoring method of welding process parameters, the detection mechanism of non-destructive testing method after welding, the quality evaluation method and its advantages and disadvantages in practical application are analyzed. In addition, the development of non-destructive testing technology for resistance spot welding is prospected. Organically combining existing non-destructive testing methods, using signal processing, artificial intelligence, pattern recognition and other technologies to improve the convenience, efficiency and intelligence of detection, are the focus of future research on quality detection technology for resistance spot welding. |
