Abstract
In this paper, a 2D axisymmetric model of thermoelectric Finite Element Method (FEM) is developed to analyze the transient thermal behavior of Resistance Spot Welding (RSW) process using commercial software, called ANSYS. The determination of the contact resistance at the faying surface is moderately simplified to reduce the calculating time, while the temperature dependent material properties, phase change and convectional boundary conditions are taken account fur the improvement of the calculated accuracy. The thermal history of the whole process (including cooling) and temperature distributions for any position in the weldment is obtained through the analysis.
