This report describes the simulation of temperature at weld interface on friction welding. It was observed that the jointed region was occurred at the center portion on weld interface under the experiment. The simulation was noticed the yield stress at weld interface of specimen and made the model for the jointing mechanism. The analysis of temperature at weld interface was based on the jointing mechanism and applied two-dimensional unsteady-state conduction equation. The jointed region was occurred at the center portion so that the temperature of the center portion supplanted that of the periphery (outer surface) for yield stress depended on the temperature at weld interface. Comparing with the calculated and experiment values for the temperature at axial direction of specimen, it was approved that the slope of temperature coincided well. As a conclusion it is considered that the jointing mechanism was predicted by the simulation.
