摘要： 摘要：
利用SORPAS软件对超高强度热成形钢板建立了描述点焊熔核形成过程的轴对称有限元模型.通过数值模拟，定量揭示了热成形钢点焊过程中温度场、熔核直径等过程量的变化规律.对比模拟计算与实测结果表明，该模型是可行的，可为超高强度热成形钢的电阻点焊提供指导. 关键词：

Abstract: Based on the software SORPAS, an axial symmetric finite element model for the resistance spot welding process (RSW) of ultrahigh strength hotformed steel (UHSS) was established. By numerical simulation, change rules of the temperature field, the nugget size, etc during the spot welding were discovered quantitatively. Comparing the numerical simulation results with the experimental measured ones, it was proved that the finite element model is feasible. It can also provide guidance for the RSW process of the UHSS.
