Dissimilar material joint, structure in which dissimilar material joint is used, and method of producing the same

A method of producing a structure in which a dissimilar material joint is used, the method comprising:

• fabricating a plurality of segments;
• fabricating a dissimilar material joint by consecutively arranging the plurality of segments in a longitudinal direction;
• joining one side of the dissimilar material joint and a first structural member together by welding;
• and
• joining another side of the dissimilar material joint and a second structural member together by welding, wherein
• fabricating the plurality of segments includes:
• joining a first member and an intermediate member together in a stacking direction by explosive welding, the first member being formed of a same material as a material of the first structural member;
• joining the intermediate member and a second member together in the stacking direction by explosive welding, the second member being formed of a same material as a material of the second structural member;
• and
• forming a recess in a joint end face of each segment, the joint end face being joined to another one of the segments, the recess spacing apart an end face of the first member and an end face of the second member from each other in the stacking direction along the joint end face, and
• fabricating the dissimilar material joint includes:
• joining together the end faces of the respective first members of the segments that are adjacent to each other by welding;
• and
• joining together the end faces of the respective second members of the segments that are adjacent to each other by welding.
