提升机滚筒开焊的补焊焊接应用

Elevator Drum Opens Patching Welding Application Which Welds

主要研究提升机滚筒开焊的补焊焊接工艺,从焊条的选择,电焊机的选择,电焊机电流的计算,极性确定(反接法)以及电弧长度的控制等方面进行分析,并在实际焊接过程中进行应用,通过多层、窄焊道、快速焊接方法,达到了预期的结果。

The cylinder snaps welding a hoister, is the calculation studying the bonding technology, choice, electric welding machine choice , electric welding machine from the welding rod are voltaic mainly, The polarity is ascertained and the electric arc length controlling, before big workpiece weldings process application, have reached expected result by muhilayer, narrow welding bead, fleetness welding method.
