Document Type and Number:

Japanese Patent JP6964530

Kind Code:

B2

Abstract:

In a joining structure for pipes wherein a first pipe (51) and a second pipe (53) are joined, a cylindrical joint (55) is formed in the peripheral surface of the first pipe (51), and the end surface of the second pipe (53) is abutted and joined to an end surface of the joint (55) by welding. The joint (55) is formed from additive-manufactured article W wherein a weld bead (25) of melted and solidified filler metal M is laminated on the peripheral surface of the first pipe (51). Thus, sufficient bonding strength can be assured while minimizing costs, and also joining can easily be accomplished.
