| Abstract: | A finite element analysis model was established for resistance spot welding of electrical contacts. The contact resistance of the contact interface was researched and the boundary conditions were applied. Temperature field and current density field in the nugget were obtained through the analysis. At tbe same time, the effect of welding technology on the electrode temperature field and thermal stress was investigated. The results show that prolonging the welding time can reduce the thermal stress to a certain extent. |
| Keywords: | resistance spot welding (RSW) electrical contacts finite element method nugget welding technology temperature field thermal stress |
