| Abstract: | Based on finite element theories,the electric-thermal-structure coupled model of resistance spot welding with dome-shaped electrode was built. Using the ANSYS sofiware, the nugget formation, growing and cooling during spot welding were analyzed. The distribution of the temperature field and stress-strain field and the change of the contact area in the welding were gained by the simulation. The correctness of the electric-thermal-structure coupled model has been identified by some experiments. |
