Abstract

In this paper, firstly, experiments are carried out to evaluate the influence of three key parameters including weld current, weld time and electrode force in nugget diameter and tensile strength in projection welding. Then, a 2-D axis-symmetric finite element model is developed to simulate the projection welding and predict the nugget diameter. Finally, the FEM results are compared to experimental data to verify the simulation model and simulated results. In the finite element model, the temperature-dependent material properties are taken into account.
