Characteristic analysis of copper/steel composite joint bypass-current wire-heating PAW on additive manufacturing

  • 摘要: 以旁路热丝等离子弧焊接方法为技术手段,选择304不锈钢和S201紫铜焊丝为增材材料,开展铜/钢复合接头电弧增材试验,研究增材顺序对异种金属增材成形的影响,对铜/钢复合接头的界面微观组织进行分析,并测试铜/钢复合接头的力学性能. 结果表明,采用先铜后钢的增材顺序,可有效防止铜/钢增材时的熔池塌陷问题,获得成形良好的铜/钢增材接头;由于泛铁现象的存在,铜/钢界面处的硬度和力学性能显著提高,复合接头的抗拉强度为256.8 MPa,断裂发生在铜侧,其断面收缩率为52.8%,断后伸长率为15.68%,断裂形式为韧性断裂.
