摘　　要：阐述了药芯铝焊丝的制造原理 ,研究了 TIG直流正接焊接铝合金的工艺特点。试验结果表明 ,用具有去除氧化铝薄膜效果的药芯焊丝作填充材料 ,采用直流正极性 TIG焊接法可以使用普通的直流 TIG焊机焊接铝合金 ,该方法集中了钎焊和直流反接 TIG焊接法的优点。并简述了直流正极性焊接铝合金所存在的问题和应用前景。This paper has explained the manufacture principle of Al-flux-cored welding wire, and studied the technical characteristics of Aluminium alloy welding with straight polarity direct current TIG method. The results of the test indicate:by using flux-cored wire which can get rid of Alumina films as packing material and adopting straight polarity direct current TIG welding method, Aluminium alloy can be welded by ordinary direct current TIG machine. This method takes advantage of both brazing and reversed polarity direct current TIG welding method. The existing problems and application prospects of Aluminium welding with straight polarity direct current method are sketched out in this paper.
