Abstract

A simple model for torque in friction stir welding is developed, based on a sliding/sticking condition in the contact interface, correlating the fundamental response variables temperature and axial force to torque. The model is validated by experiments using a special test rig enabling the precise measurement of the response variables. From the measured torque and axial force the friction coefficient μ_f is calculated and analyzed. It is observed that μ_f increases with decreasing rotation speed and drops with abrupt stepups of the plunge depth, μ_f is found to mainly vary in the range of 0.3-0.4.
