摘要
文章介绍了在汽车设计过程中,设计的安装件与M5焊接螺柱匹配时,由于安装板件料厚与M5焊接螺柱焊接强度的匹配不合理,导致安装打紧螺母时焊接螺柱脱落现象。文章阐述了寻找焊接螺柱脱落问题原因思路和方法,深入剖析问题的本质原因。
This article introduces the welding stud fall-off status in nuts tightening caused by the mismatching between designedmounting material thickness and M5 studs welding strength in vehicle design phase. It also explained the idea and method about the reason for welding stud fall-off, and the further analysis about the root for the problem.
