Abstract:The weld brazing of 6 mm thick copper plates without preheating was investigated. The weld metal of weld brazing is composed of α-Cu solid solution and Cu–Ag–P eutectic structure, and the α-Cu solid solution in the weld metal of weld brazing is larger than that in the brazing weld. The average hardness values within the weld are 60 HV (50 g) lower for weld brazing than for brazing. In all weld brazing specimens tested, the failure was located in the heat affected zone with a tensile strength slightly lower than the base metal but similar to the arc welding joints.
