1.引言 焊接是金属加工工艺范围中最重要的接合技术之一。从各种气体保护焊接方法中选定对MIG—MAG焊接进行电视监控。在这种应用广泛的焊接方法中,在保护气体罩下电弧在连续添加的溶化焊条和工件之间燃烧。 过去的研制工作只是不断地使手工焊接向机械焊接发展。因而使焊接过程限制得很死
1. Introduction Welding is one of the most important joining techniques in the metalworking process. Selected from various gas shielded welding methods MIG-MAG welding TV monitoring. In this widely used welding method, the arc is burned between the continuously added molten electrode and the workpiece under the protective gas shield. In the past, the research and development work only continuously made manual welding to mechanical welding. Thus limiting the welding process to death
