Abstract
A metal joined body in which a joint is formed from a first metal member and a second metal member. Brazed joint portions provided intermittently with a brazing material and solder joints filling the spaces between the brazed joint portions with a solder having a fusion point lower than the brazing material, are formed at a seam of the joint. The resulting metal joint has excellent sealing properties and little thermal strain.
Claims12
A metal joined body comprising:
- a joint formed by a first metal member and a second metal member,
- wherein brazed joint portions, which are formed of a brazing material and disposed intermittently, and soldered joint portions, which are formed of a solder having a lower melting point than the brazing material and fill between the brazed joint portions, are formed at a seam of the joint.
A method for manufacturing a metal joined body, comprising:
- a step of forming a joint by a first metal member and a second metal member;
- a step of intermittently forming brazed joint portions at a seam of the joint by braze joining with a brazing material;
- and
- a step of forming soldered joint portions between the brazed joint portions by using a solder having a lower melting point than the brazing material so that the soldered joint portions fill between the brazed joint portions.
