Studies were carried out on tensile properties of friction stir welded joints under the combination of 5083, 6N01 and 7N01 alloys of 8mm thick parent materials by two or three fabricators and four ways of the friction stir welding procedures and also difference in the tensile properties caused by the dissimilarities. In 5XX joints with 5083 parent materials, the averaged joint efficiency of 100% was calculated in FSW and also in M1G joints, but FSW joints showed slightly higher tensile properties than MIG joints. In 6XX joints with 6N01, the joint efficiency of 77% in 61X joints, 73% in 62X joints and 72% to 82% in 63X joints, were calculated, respectively, which were higher than those of MIG joints. In 7XX joints with 7N01, the joint efficiency of 100% was calculated, where FSW joints showed higher tensile properties than MIG joints. Difference by dissimilarities in parent materials was recognized in both 6XX and 7XX joints and that in FSW procedures was clarified limitedly in both joints. Under their specified combination, higher tensile properties were obtained.
