摘要： 在变动焊接电流下检测电弧电压，考察A-TIG焊电弧收缩及活性剂的影响。采取适当地试验方法研究A-TIG焊活性剂对电弧现象及活性剂涂敷量对焊接熔深增加的作用。结果表明，A-TIG焊电弧是否产生收缩与所使用的活性剂有关，即使在电弧未产生收缩情况下，表面活性剂仍然对焊接熔深的增加有较大的作用。

关键词: A-TIG焊, 电弧收缩, 焊接熔深, 活性剂

Abstract: The effect of active flux and arc shrinking in A-TIG welding is studied through detecting arc voltage with variant welding current. And the effect of spreading fusion of active flux on weld pool depth and arc phenomenon in A-TIG welding is also studied with properly experimental method. The results show that whether the arc of A-TIG welding shrinks is related with active flux used. The surface active flux still has the effect on weld pool depth even when arc does not shrink.

Key words: Active flux, Arc shrinking, A-TIG welding, Weld pool depth
