Resistance Spot Welding is being used in the industry for sheet joining process especially in the automobile and aerospace industry. The complicated behavior of this process must be analysed to set the optimum parameters to get the optimum weld quality. This paper presents the FEA simulation of the RSW process. It requires modelling of complex interactions between electrical, thermal, metallurgical and mechanical phenomena. A 2D axisymmetric FEM model has been developed to analyse the transient thermal behaviors of process using ANSYS software and coupled structuralthermoelectric analysis is performed by using advanced coupled field element PLANE223 to simulate the thermal characteristics of RSW process. The objectives of this analysis is to understand physics of the process and to develop a predictive tool reducing the number of experiments for the optimization of welding parameters.
