。In this solid-phase bonding technology, the cleanliness of the bonding interface is maintained by an argon seal, but if no insert material is used, the problem of generation of residual stress due to deformation, structural change, and transformation of the constituent metals may occur. Even if an insert material is used, there is a problem in that the insert material melts or becomes molten at the end of the joint surface, so the insert material leaks and the ends of the joint surface are not effectively joined.

ある。[Problems to be Solved by the Invention] In view of the problems of the prior art as explained above, the present inventor has conducted extensive research, and as a result, the present invention has been developed to reduce the thermal influence on the constituent metals to be joined. However, when using an insert material, we have developed a joining method that can efficiently produce a near-net-shape joined product and also prevent leakage of the insert material at the end of the joint surface.
