Research on Resistance Spot Welding Process of Hot-Stamped Steel BTR165

摘要：

　　Resistance spot welding of BTR165 was applied to study property of its joint by using power-frequency alternating current welding equipments.The tension strength, hardness distribution,microstructure and tensile fracture appearance were analyzed.The test results show that the hot-stamped steel has good weldability and could obtain better performance by optimizing technology.The microstructure of spot welded metal is martensite (M), tensile failure mode is button pull-out fracture, The fracture morphology has plastic dimple characteristic.

关键词： power-frequency alternating current welding equipments hot-stamped steel martensite button pull-out
