气保护电弧单面焊接时,短路次数同焊丝与熔池前端的距离密切相关.将短路次数保持在某一定值,能获得良好的背面焊道.本文介绍了一种控制背面焊道的新方法.
When the gas is arc welding, the number of short circuits is closely related to the distance between the welding wire and the front of the weld pool, and the number of short circuits can be maintained at a certain value to obtain a good back weld.A new method to control the back weld is introduced in this paper .
