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.
