JOINING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/213493
Kind Code:
A1
Abstract:
A second member (20) is constituted by a material that is difficult to weld to a first member (10). A depression (11) is formed in the first member (10) by press molding so that a lower-surface side of the first member (10) on a side opposite to the second member (20) protrudes. A third member (30) is arc-welded toward at least a bottom-part side of the depression (11) with a penetration part (21) of the second member (20) interposed therebetween. The second member (20) is compressed with a flange (31) and the first member (10) by solidification contraction of the third member (30), whereby the second member (20) is secured between the flange (31) of the third member (30) and the first member (10).
