单组分氟化物对钛合金氩弧焊电弧形态的影响

Effect of single-component fluoride flux on TIG arc shape for Ti alloy

摘要: 针对厚2.5 mm的BT20钛合金平板,沿不同氟化物涂层进行TIG焊接工艺试验,对沿不同氟化物TIG焊接过程中的电弧形态以及焊后焊缝成形进行了研究,并与相同焊接工艺参数下的常规TIG焊进行了对比。试验结果表明,不同的单组分氟化物对焊接电弧形态的影响有较大区别,并由此总结出了电弧形态变化与焊缝熔深的关系。

Abstract: BT20 titanium alloy of 2.5 mm thickness was welded by conventional TIG and single-component fluoride flux TIG,respectively.The results showed that the influences of different single-component fluorides on the shape of arc are different.And the relationship of arc shape and the weld penetration was also obtained.
