PURPOSE:To join satisfactorily joint parts without the outflow of a brazing filler metal, generation of voids, etc. by forming preliminarily the insert layers of the brazing filler metal to one or both of the joint surfaces of members, superposing the joint parts and heating the superposed parts to the melting temp. of the brazing filler metal or above. CONSTITUTION:The insert layers E1, E2 of the brazing filler metal are preliminarily formed on one or both surfaces to be joined of the metallic members A, B. After the joint parts are superposed, the joint parts are heated to the melting temp. of the brazing filler metal or above. The joint parts are then satisfactorily joined without the outflow of the brazing filler metal and without defects such as voids. The equally good result is obtd. even by disposing the brazing filler metal C to the end edge of the joint part to assure the stronger joint.
