Abstract
A welding method of a diffusion bonded structure in which the diffusion bonded structure formed by diffusion bonding metal parts to each other is bonded to another part by fusion welding includes a buffer layer forming step of forming a buffer layer in a welding region including a diffusion bonded joint of the diffusion bonded structure, the buffer layer having greater ductility than the diffusion bonded joint, and a welding step of bonding the welding region in which the buffer layer is formed to the another part by performing the fusion welding from above the buffer layer.

A welding method of a diffusion bonded structure in which the diffusion bonded structure formed by diffusion bonding metal parts to each other is bonded to another part by fusion welding, the welding method comprising:
- a buffer layer forming step of forming a buffer layer in a welding region including a diffusion bonded joint of the diffusion bonded structure, the buffer layer having higher ductility than the diffusion bonded joint;
- and
- a welding step of bonding the welding region in which the buffer layer is formed to the another part by performing the fusion welding from above the buffer layer.
