Modeling of continuous drive friction welding of mild steel

In this study, a two-dimensional model was developed for continuous drive friction welding (CDFW) of mild steel based on the redevelopment environment of ABAQUS software. The influences of axial pressure and rotating speed on interface temperature and axial shortening were examined. The results show that increasing axial pressure, the weld interface can reach a quasi-stable temperature more quickly and the axial shortening will be larger. Similar findings were observed with increasing the rotating speed. In addition, with the increase of friction time, the interface temperature remains stable and axial shortening increases linearly with time. Experiments with mild steel bars were also conducted. The simulation results are comparable to the experiments.
