| 摘 要： | 针对不锈钢,提出一种新型活性TIG焊方法——电弧辅助活性TIG焊,即AA-TIG焊。采用CO2+Ar作为小电流钨极电弧的保护气体进行单弧AA-TIG焊,分别研究小电流钨极电弧和正常TIG焊工艺参数对焊缝熔深的影响,并针对试验范围内的最佳焊接规范研究不锈钢AA-TIG焊的焊缝成形、焊缝显微组织、化学成分和焊缝性能。采用AA-TIG焊可以单道焊透10mm厚的不锈钢板材,单面焊双面成形。与传统TIG焊相比,焊缝组织和化学成分几乎没有变化,焊缝的耐Cu/CuSO4腐蚀性能和低温冲击韧度都满足相关标准要求。

| Abstract: | A new activating TIG welding process for stainless steels called AA-TIG welding is proposed.The CO2+Ar mixing gas is used as the activating mixing shielding gas of the low current tungsten electrode arc.A series of single-arc AA-TIG welding experiments are made to study the effects of experimental parameters of low current tungsten electrode arc and normal TIG welding on the weld penetration of AA-TIG welding.For the optimal process parameters,the weld forming,weld microstructure,weld composition and weld p... |
