DISSIMILAR MATERIAL JOINT AND STRUCTURE USING DISSIMILAR MATERIAL JOINT AND METHOD FOR MANUFACTURING SAME

摘要

A dissimilar material joint (50) is formed by arranging a plurality of joint segments (44) consecutively in a longitudinal direction. Each joint segment (44) is formed by joining and integrating together a first member (51), an intermediate member (55), and a second member (54) by explosive welding. A groove (62) is formed in a joint end face of each joint segment (44), the joint end face being joined to another one of the segments (44), the groove (62) spacing apart an end face of the first member (51) and an end face of the second member (54) from each other in a stacking direction. In the dissimilar material joint (50), the end faces of the respective first members (51) of the joint segments (44, 44) that are adjacent to each other are joined together by welding, and the end faces of the respective second members (54) of the joint segments (44, 44) that are adjacent to each other are joined together by welding.
