摘　　要：镀锌钢板MIG/TIG电弧钎焊与普通电弧焊相比,电弧钎焊电弧热量集中,对薄板及薄壁容器进行钎焊时变形量很小,焊接热影响区小,操作方便,节能高效又易于实现自动化,同时又因其电弧特有的“阴极雾化”去除氧化膜作用、带电离子和电子的冲击活化作用,以及克服钎剂对母材的腐蚀副作用,焊后不用清洗,在生产上,特别是汽车部件及电器制造上得到广泛应用。。Compared to common electric arc welding,MIG/TIG electric arcbr aze weling has advantages of good electric arc heat concentration,small deforma tion when welding steel sheet and sheet container,small effected area by weldin g heat,convenicnt operation,energy saving and being easy to realize automatio n.And its particular 'cathode atomization'has function of removing oxide film. lmpact and activation of charged ions and electrons can overcome the side offec t of erosion of brazing flux to base metal and need not to wash welded parts.MI G/TIG electric arc braze welding has been widely used in production,especially in manufacturing of auto components and electric appliance.
