不同Cr-Mo钢现场焊接工艺探讨

Discussion of the Spot Welding About Different Kinds of Cr-Mo Ste el

针对石化工业中出现的Cr-Mo钢焊接接头碳迁移现象 ,采用模拟的方法 ,对不同Cr -Mo钢材料异种钢焊接接头进行了工艺性探讨。结果表明

According to the phenomenon of the carbon removin g of the welds in the petrochemical industry and the simulated way it takes, this article gives a technologic discussion for unusual steel's welds of different ki nds of Cr-Mo steel. The consequence indicates that fairly satisfactory welds can be got if using reasonable welding and heat treatment technology.
