摘　　要：在氩弧焊工艺试验基础上,分析了铝合金表面氧化膜和焊接工艺方法对铝合金焊缝中气孔的影响。结果表明:通过对铝合金母材和焊丝表面状况、惰性气体的纯度、焊接工艺参数等的合理控制,可以有效减少铝合金焊缝中的气孔。On the basis of Ar-arc-welding procedure tests, the influences of oxidation film and welding process for aluminum alloys on the porosities in the aluminum welds were researched. The results show that the number of porosities in the weld can be decreased by reasonably controlling the surface conditions of base materials and solder wire, purity of shielding gases and welding parameters and so on.
