Document Type and Number:
WIPO Patent Application WO/2023/167264
Kind Code:
A1
Abstract:
In this dissimilar-material joined body, a steel material and a stud-equipped aluminum member, in which a steel stud member is attached to an aluminum material, are joined together by fusion joining. The stud member comprises a head part and a shaft part. The shaft part penetrates an aluminum material in the plate-thickness direction, protrudes therefrom, and has, at an apical end of the protruding shaft part, an enlarged-diameter section that spreads radially outward. A rear-side surface of the head part that faces the aluminum material is swaged together with the aluminum material. The head part and the steel material are fused and joined together in such a manner to form a gap of a prescribed distance between the aluminum material and the steel material.
