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

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.
