Abstract
Tool pin geometric features are important parameters in friction stir welding (FSW). They influence weld quality through their effects on material flow and consolidation during FSW while also affecting the in-plane process forces and the necessary level of forge force. In this paper, volumetric defect content as a function of pin features on mildly tapered conical, threaded, pins was examined in 6061-T6. Features included flats, co-flow flutes and counter-flow flutes. Feature effects on the magnitude and direction of the resultant in-plane force was also examined. Variation of applied forge force, other process response variables (torque, power, temperature) were also extracted to provide information regarding their dependence on tool pin features for a given set of welding parameters.
