摘　　要：采用高能量密度等离子束流对CuZnAl合金进行熔化焊和熔压焊两种方法的研究。结果表明:熔焊连接CuZnAl合金丝,由于等离子流力使得熔池塌陷导致接头的实际结合截面减小,焊后试样的抗拉强度只能达到母材的9.97%;采用熔压焊连接CuZnAl合金丝,夹具能有效挤压焊缝从而获得较好的焊接接头,焊接接头抗拉强度达到母材的90.1%,且接头相变伪弹性与母材非常接近。Fusion welding and fusion pressure welding was used to weld Cu-Zn-Al alloy based on high energy density plasma beam.The results show that the plasma flow force make the molten pool be collapsed in fusion welding process,which leads to the reduction of joint crosssection, so the tensile strength of the joint can only reach up to 9.97% of base metal.In fusion pressure welding,the weld can be squeezed,and a better welded joint can be obtained.Its tensile strength can reach up to 90.1 % of base metal,and the capability of pseudo-elastic phase transition is close to the base metal.
