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.
采取适当的试验方法研究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。
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.
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。
