焊接技术目前已经成为金属加工的主要方法之一。第一机械工业部以(77)一机技字789号文,要求在焊接行业重点推广六项焊接与切割新工艺。现将它们简介如下:一、二氧化碳气体保护焊气体保护焊是五十年代初期发展起来的高效焊接工艺。CO_2气体保护焊,是用 CO_2气体作为保护气体的一种先进的焊接技术。配合成分适当的焊丝,它可以焊接低碳钢、合金钢和
Welding technology has now become one of the main methods of metal processing. First Machinery Industry Department to (77) a machine technology word 789, requiring the welding industry to promote the six welding and cutting new technology. Now they are briefed as follows: First, carbon dioxide gas shielded welding gas shielded welding is the development of the early 50s efficient welding process. CO 2 gas shielded welding, CO 2 gas is used as a protective gas welding technology advanced. With the appropriate composition of the wire, it can be welded mild steel, alloy steel and
