tension weld

The low surface tension and low viscosity of aluminum alloys are the reason that the change of surface tension temperature gradient is not the main mechanism of activating flux increasing weld penetration of activating TIG welding.

而铝合金材料表面张力小，粘度低，是导致表面张力温度梯度改变不是活性剂增加铝合金活性TIG焊熔深的主要机理的重要原因。
