电阻焊质量稳定性试验是评价焊接设备性能的关键环节。由于影响接头质量稳定性的因素很多,因此试验难度大,失败率较高。本文从塑性环面积、工艺参数、气缸结构和试验方法等方面对影响点焊接头质量稳定性及其评价的因素进行了分析,并提出了有效的解决方案。 Resistance welding quality stability test is to evaluate the performance of welding equipment, the key link. Due to the many factors that affect the stability of the joint quality, the test is difficult and the failure rate is high. In this paper, the factors affecting the quality and stability of spot welded joints and their evaluation are analyzed from the aspects of plastic ring area, process parameters, cylinder structure and test methods, and some effective solutions are put forward.
