Resistance Spot Weldability of Hot-formed Ultra High Strength Steel Based on Virtual and Physical Experiment

摘要：

　　In this study, virtual and physical experimental investigations were performed on the resistance spot weldability of hot-formed ultra high strength steels (UHSS).The sheets were joined by the resistance spot welding as lap or cross joint.The mechanical properties were assessed in terms of cross tension strength (CTS) and tensile shear strength (TSS).The micro structural profile and weld nugget diameter were also investigated.Both virtual and physical methods yielding results are in good agreement.The results are discussed in the light of earlier work published in the literature and contribute to a better understanding on the evaluation of resistance spot weldability.
