Title:
DISSIMILAR MATERIAL JOINT STRUCTURE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/157335
Kind Code:
A1
Abstract:
A beam structure (30) made of the same material as a second member (20) is formed on a surface (21) of the second member (20) by a three-dimensional shaping technique. The beam structure (30) includes a pillar portion (31) erected on the surface (21) of the second member (20), and a beam portion (32) connected to the pillar portion (31). The first member (10) before solidification is filled on the surface (21) of the second member (20) and in the internal space (33) of the beam structure (30) and then solidified. As a result, a dissimilar material joint structure (1) is produced in which the first member (10) and the second member (20) made of a material different from that of the first member (10) are joined. Therefore, a dissimilar material joint structure making it possible to obtain a stronger joining force and a method for producing the same are provided.
