摘　　要：为解决某车型部分位置铝螺柱焊接质量较差、掉落较为频繁的问题,通过ANSYS软件对焊接过程中产生的磁场及产生的电磁力进行模拟,确认原因为焊接过程中焊接电弧受到铁磁物质的影响偏离,产生了磁偏吹现象,经过试验确认了降低焊接电流从而减小磁偏吹的措施并实施。结果表明:减小电流能够有效解决焊钉掉落问题,并总结相关规律为后续车型焊钉焊接提供参考。In order to solve the problem of poor welding quality and frequent falling off of aluminum studs for a vehicle,this paper simulated the magnetic field and electromagnetic force generated in the welding process by ANSYS software,and confirmed the cause was magnetic blowing generated by the deviation of the welding arc caused by the influence of ferromagnetic substances during the welding process.Test confirmed the measures of reducing welding current to reduce magnetic blowing and put into practice.The results show that reduction of welding current can effectively solve the problem of welding stud falling off,relevant rules are summarized,which provide reference for welding stud welding of subsequent vehicle models.
