我厂年体车间是客车钢结构总成车间,焊接工作量约占总工时的一半。近几年,推广使用了CO_2气体保护半自动焊、侧墙多头点焊、车顶侧板滚焊等多种新工艺,使车间的工艺面貌起了新的变化,产量、质量都有了很大提高。但是梁、柱与外板的塞焊联接问题,却一直得不到解决。在批林批孔运动深入发展的大好形势鼓舞下,我们参考了国内外有关资料,根据近几年来我们在使用CO_2气体保护焊方面的经验,经过半年多的艰苦奋战,试验成功了CO_2气体保护半自动点焊新工艺。
I plant the annual body shop bus assembly workshop, welding workload accounts for about half of the total working hours. In recent years, the promotion of the use of CO_2 gas protection semi-automatic welding, sidewall multi-spot welding, welding the roof side panels and many other new technology, the process of making a new face of the workshop, production, quality have a great improve. But the beam, column and the outer wall of the plug welding connection, but has not been resolved. Inspired by the excellent situation of the further development of the operation of Lin Pikai Movement, we have consulted the relevant information both at home and abroad. Based on our experience in using CO 2 gas shielded welding in recent years, after more than half a year of hard work, we successfully tested CO 2 gas protection Semi-automatic spot welding new technology.
