Numerical study on the effect of electrode force in small-scale resistance spot welding

Since electrode force is an important process parameter in small-scale resistance spot welding (SSRSW), its effects on the electrical, thermal and mechanical behavior of the welding process when using direct current have been studied numerically in the present paper using the finite element method. The variations of contact radius, current density distribution and temperature profile at the sheet/sheet (S/S) and electrode/sheet (E/S) …
