一种新型Cu基自蔓延焊接接头组织和性能

Structure and performance of a new Cu-base SHS welded joint

    摘要
  • 摘要: 针对在野外条件下金属零部件的焊接应急修理困难的问题,以CuO+Al系铝热剂反应为放热源,开发了一种新型Cu基自蔓延焊接材料,对其焊缝的组织形貌及性能进行了研究。结果表明,自蔓延反应后形成熔焊焊接,焊缝成形良好,焊缝与基体之间存在明显的过渡区,焊缝的抗拉强度大于200MPa,抗弯强度接近600MPa,表面硬度可达HRB130,能够满足金属零部件野外应急维修需要。

     

    Abstract: A new cuprum-base SHS welding material was devel-oped by SHS combustion between CuO and Al in order to solve a problem that welding mend of metal parts was difficult in field.The structure and performances of the welded joint were studied.The re-sults indicated that thewelding was fusion welding, and weld appear-ance is good. Transition zone was clear between base metal and weld metal.At the same time, tensile strength of the welded joint was higher than 200 MPa, and bending strength was close to 600 MPa and surface hardness was also close to HRB130.It also indicated this technology can meet the need of repair of metal parts in field.
