BRAZING METHOD

摘要

A method for brazing a first metal member (1), on which an oxide forms during brazing, and a second metal member (2), in which a high-wettability metal (3) having a wettability with a brazing filler metal that is higher than that of the oxide is applied to at least a brazing surface of the first metal member (1). The first metal member (1) and the second metal member (2) are then joined by heating the brazing filler metal (4) to melt the brazing filler metal (4). The oxide covering film (Ia) is formed on the portion of the surface of the first metal member (1) to which the high-wettability metal (3) was not applied.
