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。结果表明，Ａ－ＴＩＧ焊电弧收缩是焊接熔深增加的一项重要原因，电弧是否产生收缩与所使用的活性剂有关，然而，既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作用。The effect of active flux and arc shrinking in A - TIG welding is studied through detecting arc voltage with variant welding current to this paper. And the effect of fusion of active flux on penetration and arc phenomenon in A - TIG welding is also studied with properly experimental method. The results show that the arc of A - TIG welding shrinks in relation to using of active flux. The surface active flux still has the effect on penetration even when arc does not shrink.
