混合气体保护焊接,已趋普遍推广使用。在外国,特别是西德,CO_2、Ar混合气体保护焊接已被应用在船用机械、车辆的生产中,在重工业的各个行业中应用也很普遍。我厂与西德利布赫尔公司合作生产船用起重机——克令吊。在该公司所属的南茨厂所有的冷焊件中全部采用CO_2+Ar混合气体保护焊,手工电弧焊几乎全被淘汰。为此我厂在引进该项产品的制造中,同时引进了南茨厂的焊接工艺。采用了CO_2、Ar气体混合集中供气装置,使用西德CLOOS产家的焊机,其效果良
Mixed gas protection welding, has been widely promoted use. In foreign countries, especially West Germany, CO_2, Ar gas welding has been used in the production of marine machinery and vehicles, and is also widely used in various industries of heavy industry. I plant and Sidley Liebherr co-production of marine cranes - 克 令 hanging. In the company owned Nanzi plant all the cold weldment of all CO_2 + Ar mixed gas shielded welding, manual arc welding almost all be eliminated. To this end I plant in the manufacture of the introduction of the product, at the same time the introduction of Nanci plant welding process. Using CO_2, Ar gas mixture of centralized gas supply device, the use of West Germany CLOOS production welder, the effect is good
