Abstract
The butt and lap configurational friction stir welding of type 304 stainless steel was conducted in this study. The sound joints were obtained by WC tool. As the welding distance increased, tool deformation gradually increased at the pin edge. The discoloration by oxidation was observed at the top surface of the joint, a sufficient heat-input was required to avoid the welding defect owing to the lack of stirring at the welding start point. Very fine grains were observed in the stir zone, and the grain coarsening was not observed in the heat affected zone.
