焊接过程操作简单

可重复性强

接头的抗拉强度可以达到镁合金丝材的80%

并且具有良好的抗弯能力。

Abstract

In order to realize the recycling use of the scrap wires of AZ31 Mg alloy

the wires were joined using TIG spot welding.The microstructure and mechanical properties of welded joints of magnesium alloy wires were analyzed by scanning electron microscope

metallurgical microscope and universal testing machine.The results reveal that TIG spot welding technology can realize a reliable joint of the scrap magnesium alloy wires.The tensile strength of the joints can reach 80% of the substrate material.In addition

the joint has good bending resistance.
