<p>PROBLEM TO BE SOLVED: To provide a soldering method for soldering by using not any flux but a breakage action of an oxide film by Mg, wherein the soldering method has more excellent and stable solderability and can be industrially applied.SOLUTION: A soldering method solders an Mg containing aluminum alloy brazing sheet having a core material clad with a solder, and either another brazing sheet or an aluminum alloy member. The brazing sheet and a groove substantially in parallel with a tangent line contacted by the jointed material are formed in the surface of any of the brazing sheet, the core of the brazing sheet, the core of the other brazing sheet, and the aluminum alloy member, and in the vicinity of the tangential line; by melting the solder material not by using a flux but by heating the solder material in an inert gas atmosphere; and by flowing the molten solder material to the groove, to solder either the brazing sheet and the other brazing sheet or the brazing sheet and the aluminum alloy member.</p> |
