BRAZING METHOD OF METALLIC MATERIAL

PURPOSE:To prevent the generation of a defect such as a hole, etc., in a brazing filler metal, to increase the joining strength, and also, to prevent the generation of a leakage. CONSTITUTION:On the outside peripheral surface of an insertion part to a cylindrical outer projecting part (14) of a plen...

Zusammenfassung:	PURPOSE:To prevent the generation of a defect such as a hole, etc., in a brazing filler metal, to increase the joining strength, and also, to prevent the generation of a leakage. CONSTITUTION:On the outside peripheral surface of an insertion part to a cylindrical outer projecting part (14) of a plenum chamber (2) of a branch pipe (5) and a cylindrical outer projecting part (10) of a connecting member (7), plural grooves (12), (13) which extend in the axial direction are formed. Depth of the grooves (12), (13) is set to 0.5-1.5mm. The grooves (12), (13) are formed at an interval of 5-30mm in the peripheral direction. In such a state, by a preplaced brazing method, the branch pipe (5) and the cylindrical outer projecting parts (4), (10) are brazed.
