Abstract
In the present study, thermal history have been determined for joined copper sheets under various welding conditions using Frigaad relation, numerically. The obtained results were compared with the experimental results and it was found that there is a good agreement between them. Also, it was found that the traverse velocity mainly affects the amount of transferred heat and the rotational speed changes the temperature of the welding process. This study cleared that in all welding conditions at first, the thermal history diagrams predicted using Frigaad relation are lower than the diagrams obtained from the experiments and then, the trend of process diagrams reverses and the simulation diagrams place higher than the experiment diagrams. In addition, Signal-to-noise analysis shows that shoulder diameter is a significant factor and plays a major role in affecting the longitudinal tensile thermal stresses.
