CO_(2)气体保护焊短路过渡电弧点焊对接薄板技术

The technology of butt jointing thin plates by CO_(2) shielded spot arc welding with short circuit transfer

:分析了CO2 气体保护焊短路过渡电弧点焊过程及特点 ,利用短路过渡电弧作用小的特点可进行薄板的点焊对接。点焊时 ,在短路之前使焊丝端部预先熔化 ,引弧后使焊丝熔化速度大于送丝速度 。

In this article, the process of CO 2 shielded spot arc welding with short circuit transfer is analysed.Before short circuit, melt the wire end,after arc striking, make wire feed speed less than wire melting speed, thin plates can be quickly butt jointed by CO 2 shielded spot arc welding with short circuit transfer.
