Title: PIPE JOINING METHOD, JOINT AND PIPE JOINING STRUCTURE
Abstract:
The pipe joining method according to the present invention comprises: preparing a joint (10) wherein a joining material (15), which contains a Cu-Ni alloy powder (17) and an Sn powder (16) having a lower melting point than the Cu-Ni alloy powder (17) and in which an Sn-Cu-Ni-based intermetallic compound comprising the Sn powder (16) and the Cu-Ni alloy powder (17) is formed by heating, is disposed in a cavity part (12); and, after inserting two pipes (14A, 14B) into the joint (10), heating insertion parts to form a metallic part (18) comprising the Sn-Cu-Ni-based intermetallic compound as a main phase in the cavity part (12) and forming a metallic part (19) comprising the Sn powder (16) in a molten state as a main phase in a narrow gap part (13).
