Abstract
A second member has a through-portion penetrating toward a first member. An overlapped surface of the second member with the first member includes a recess. The recess is recessed so as to surround an entire periphery of the through-portion. A sealing material is injected into the recess from an injection hole to close a gap between overlapped surfaces of the first member and the second member.
Claims6
A joint structure including a first member made of a metal material, a second member made of a material that is difficult to be welded to the first member, and a third member made of a filler material and welded to the first member, the first member, the second member, and the third member being joined together,
- the second member including a through-portion penetrating toward the first member,
- the third member being welded to the first member through the through-portion,
- at least one of overlapped surfaces of the first member and the second member including a recess formed into a space separate from the through-portion, the recess being recessed so as to surround an entire periphery of the through-portion,
- the recess being formed into a space separate from a welded part that is a welding site where the first member and the third member are welded together, the recess being recessed so as to surround an entire periphery of the welded part,
- at least one of the first member or the second member including an injection hole communicating with the recess, and
- the recess being provided with a sealing material injected from the injection hole, the sealing material closing a gap between the overlapped surfaces of the first member and the second member.
A joining method for joining together a first member made of a metal material, a second member made of a material that is difficult to be welded to the first member, and a third member made of a filler material and welded to the first member,
- the second member including a through-portion penetrating toward the first member,
- at least one of overlapped surfaces of the first member and the second member including a recess formed into a space separate from the through-portion, the recess being recessed so as to surround an entire periphery of the through-portion,
- the recess being formed into a space separate from a welded part that is a welding site where the first member and the third member are welded together, the recess being recessed so as to surround an entire periphery of the welded part,
- at least one of the first member or the second member including an injection hole communicating with the recess,
- the joining method comprising:
- overlapping the second member on the first member and welding the third member to the first member through the through-portion;
- and
- injecting a sealing material into the recess from the injection hole to close a gap between the overlapped surfaces of the first member and the second member with the sealing material.
