Study on Microstructure and Fracture Morphology of 2205 Duplex Stainless Steel Resistance Spot Welds

Abstract:

Fracture morphologies, microstructures and mechanical properties of the spot welded joints on 2205 duplex stainless steel (2205DSS) were studied by using three-phase inverter resistance welding machine with the welding currents of 6.4kA, 7.4kA, 9.5kA and 11.6kA, the welding pressures of 0.5MPa, 0.6MPa and 0.7MPa, and the welding time of 200ms. The results show that the macroscopic fracture fashion of 2205DSS spot welding joints are mainly button fracture and joint fracture, and the microstructures and mechanical properties of 2205DSS spot welding joints have the best performance with the welding current of 9.5kA, the welding time of 200ms and the welding pressure of 0.6MPa.
