Numerical and experimental parametric study of resistance spot welding process of AISI 1008 steel sheets

Ata Khabazaghdam, Abbas Fadaei, Azhdar Rahmani
In the present research, a parametric study in Resistance Spot Welding (RSW) of thin AISI 1008 steel sheets is investigated via FEM. All the time steps through the RSW process, included squeeze time, welding time, holding time and cooling time are took into account. First, the effects of various parameters such as electrical current, welding time and electrode tip diameter are investigated in the nugget geometry. Then, time history stress diagram and residual stresses are obtained in RSW weldment. FEM results are validated very well by some experiments which performed in two parts of nugget geometry and residual stresses.
