摘要
文章分析了拉弧式螺柱焊的良品条件,包含焊接电流、焊接时间、螺柱提升高度、螺柱伸出长度、焊枪状态等。焊接电流和焊接时间是对接头质量影响最大的焊接规范参数。文章结合实际生产案例,为螺柱焊接质量问题解决提供了模式化思路。弧焊对搭铁螺栓组合件影响较大,导致力矩衰减,需增加预紧力矩。
The good conditions of drawn-arc stud are analyzed,including welding current,welding time,stud lifting height,stud elongation length,welding gun status and so on.Welding current and time are the two important determinants of joint quality in welding conditions.Based on the actual production case,this paper provides a model idea for solving stud welding quality problems.Arc welding has a great influence on the bonding,which leads to the moment attenuation,the pretightening moment needs to be increased.
