<P>PROBLEM TO BE SOLVED: To provide a brazing method of high sealability by improving brazing filler metal-filling performance in a clearance of a junction part, in brazing in an inert gas not using a flux. <P>SOLUTION: This brazing method is a method of brazing the first member constituted of an aluminum alloy brazing sheet, to the second member constituted of aluminum or an aluminum alloy, Mg is contained in at least one portion constituting the aluminum alloy brazing sheet, preplaced solder of an Al-Si aluminum alloy is arranged in a clearance between the first member and the second member, the both members are heated in the inert gas without applying the flux, to be brazed, and a Mg content of the brazing filler metal filled in the clearance after brazed is brought into 75% or less of Mg content of the brazing filler metal in a portion other than the clearance, in the brazing method for the aluminum member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
