摘　　要：详细阐述了螺柱焊的焊接原理和工艺参数对焊接质量的影响。通过对前地板薄板螺柱焊缺陷进行统计分析,发现磁偏吹是导致螺柱脱焊的主要原因,分别从螺柱尺寸、零部件形状、地线接法及夹具设计等方面分析探讨造成焊接磁偏吹的原因,通过增加夹具支撑、调整接地线和优化提升高度,解决了薄板螺柱焊焊接过程中磁偏吹导致的焊接缺陷问题,提升了螺柱焊接质量。The effect of stud welding principle and parameters on welding quality is described in detail. Through statistical analysis of stud welding defects of front floor sheet,it is found that magnetic blow is the main cause of stud removal welding. The reasons of welding magnetic blow are analyzed and discussed from the aspects of stud size,part shape,ground connection method and fixture design. By increasing the fixture support,adjusting the grounding line and optimizing the lifting height,the welding defects caused by magnetic blow in the stud welding process of sheet are solved,and the stud welding quality is improved.
