PROBLEM TO BE SOLVED: To reduce the weight of a plate member composing a vehicle body, without requiring an automobile manufacture to change welding equipment for vehicle body composing members.SOLUTION: A plate member 30 is a long-shaped plate member and forms a plate-member weld structure by its being welded to other plate members. The material of the plate member 30 is a material (aluminum) which is different from a material of the other plate members. Parts 30B to be welded with the respective other plate members, of the plate member 30 are disposed by its being replaced with the same material (steel) as the other plate members. The replaced parts 30B to be welded and the plate member 30A except the parts to be welded are integrally joined into a plate by friction stir joining. In the friction stir joint, a joint line for a flat surface part X is an inclined line 44a and a joint line for a vertical surface part Y is a vertical line 44b.SELECTED DRAWING: Figure 6

    【課題】自動車メーカの自動車車体構造部材の溶接設備を変更することなく、自動車車体を構成する板部材の軽量化を図る。【解決手段】板部材30は長尺形状の板状部材であり、他の板部材に溶接にて接合されて板部材溶接構成体を構成する。当該板部材30の材質は前記他の板部材の材質とは異なる材質(アルミ材)である。そして、当該板部材30における前記他の板部材との溶接箇所部位30Bを、他の板部材と同じ材質(鋼材)に置換して配設し、該置換した溶接箇所部位30Bと当該溶接箇所部位以外30Aの板部材とを摩擦攪拌接合で板状に一体的に接合する。なお、該摩擦攪拌接合における平面部Xの接合線は傾斜線44aとし、垂直面部Yの接合線は垂直線44bとして接合する。【選択図】図6
