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

Abstract:

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.
