DW型单体液压支柱柱体焊接工艺

Craft of DW-series Single Hydraulic Prop′s Plunger Piece Weld

现有焊接工装没有自动化变位装置,并且在焊接中容易产生热裂纹等缺陷。针对单体支柱柱体焊接中出现的问题,通过改进焊接工装,调整焊接工艺参数、焊后处理等,编制一套焊接工艺指导生产,提高了产品质量。

This weld device had not quickly changed place machine and easily produce the hot crack in welding area etc.. Aims at the problem that DW- series single hydraulic prop＇s plunger piece weld, through changing weld device, adjusting to weld the craft parameter, the handles behind etc.. Establishe, a set of the crapt welding, guiding the production, insuring the product quantity.
