工艺参数对钛与铝异种金属熔钎焊铺展行为及接头力学性能的影响

Influence of process parameters on the spreading behavior of melt-brazing and the mechanical properties of welding joint of the titanium and aluminum dissimilar metal

比较了在钛、铝合金的异种金属熔钎焊过程中,焊接电流和速度对三种焊丝润湿铺展性能的影响,分析了在不同工艺条件下焊接接头的抗拉强度和硬度等力学性能的变化规律,并对焊接接头的微观断裂形貌进行了分析。

In the melt-brazing process of titanium and aluminum dissimilar metal, the in- vestigation was carried out on how welding current and speed influence wettability and spreadability of three kinds of welding wires, on the variation of tensile strength and hardness of the welding joint under different process conditions, and on the micro-fracture morphology of the welding joint.
