钨极氩弧焊用于生产以来,对我国航空工业的发展起到了积极作用。但是这项技术在我国从五十年代到七十年代期间,设备、工装和工艺都没有多大改进。有人认为这种工艺已发展到尽头,再无潜力可挖。从研究国外焊接技术中可知,目前发达工业国生产线上使用的焊接手段,最主要的还是钨极氩弧焊。焊接的材料有不锈钢、镍基合金、钴基合金、铝合金、 TIG welding for production since the development of China’s aviation industry has played a positive role. However, this technology in our country from the fifties to the seventies, equipment, tooling and technology are not much improvement. Some people think that this process has come to an end, there is no potential to dig. From the study of foreign welding technology we can see that the current industrialized countries to use the production line welding tools, the most important is the TIG welding. Welding materials are stainless steel, nickel-based alloys, cobalt-based alloys, aluminum alloys,
