Abstract
Torque is a fundamental process quantity in FSW because it is related to weld quality, process control, and mechanical properties of the weld. However, models and experimental studies to determine the influence of the tool geometry and all the process velocities on torque have received little attention. In this paper, the influence of the pin and shoulder on the torque is individually considered. The torque was measured during FSW experiments for different combinations of the tool geometry and the process velocities and a model to describe the torque as a function of the main welding parameters was proposed. The results showed a strong influence of the tool geometry on torque and a good agreement between the experimental data and the model.
