Abstract: The objectives of this research are to use a real-time temperature measurement system developed at the LAMSML to develop a combined temperature and force closed-loop control system for robotic friction stir welding (FSW) that maintains weld quality under various process disturbances. During FSW, several process parameter and condition variations (thermal constraints, material properties, geometry, etc.) are present. The FSW process can be sensitive to these variations, which are commonly present in a production environment; hence, there is a significant need to control the process to assure high weld quality. Reliable FSW for a wide range of applications will require closed-loop control of certain process parameters.
