摘要
hull (2) from the dissimilar joint 10 is applied to the structural support member 5 for supporting the structure (4) is made of different metals are first joined to the hull side member (6) 1 and the joint member 11, fillet welding to the side structure member 7 is also provided with a second joint member 12 to which the friction stir welding the first joint member (11). The first joint member 11, the second engagement surface 15 a, is formed in the approximately flat face contact with, the two joint members to each other (11 of the second joint member with the first engagement surface 14, 12 of, 12) is placed stretched in the transverse direction is also joined to each other in a plurality of columns friction stir joints 21 extending in the longitudinal direction. Is provided across a pair of fillet welds (23), the side (20) from the second joining surface 15 and the opposite cheukin welding surface 16 of the structural side member (7). Friction stir joints 21 of is disposed so as to overlap with more than one when each fillet weld (23) seen in the normal direction of the second bonding surface (15).
