Studies were carried out on characteristics of friction stir welded (FS-welded) joints under the combination of the same structural alloy of parent materials with 3 (thin), 8 (mid-thick), and 20 (thick) mm thickness by various fabricators and various ways of friction stir welding (FSW) procedures and also on whether any difference in their characteristics caused by dissimilarities in both parent materials and FSW procedures was recognized or not. This report described outline of research work on hardness and metallurgical features, mechanical properties, residual stress distribution of FS-welded joints in parent materials with 8 mm thickness and features of the joints through post-heat treatments, where difference by the above dissimilarities was clarified in some characteristics and under their specified combinations, higher properties were obtained.
