METHOD FOR JOINING ALUMINUM ALLOY MATERIAL, METHOD FOR MANUFACTURING ALUMINUM ALLOY JOINED BODY, AND ALUMINUM ALLOY JOINED BODY

摘要

PROBLEM TO BE SOLVED: To provide a novel joining method applicable to 2000-type aluminum alloy material, and an aluminum alloy joined body of high strength, and a method for manufacturing the same.;SOLUTION: In the method for joining aluminum alloy materials with the content of Mg being regulated to, by mass, ≤0.5%, aluminum alloy materials are joined with each other in the non-oxidizing atmosphere while flux is applied between the joined members at the temperature in which the mass ratio of the liquidus generated in the aluminum alloy to the total mass of the aluminum alloy materials of one joined member is 5-35%, and on the other hand, the mass ratio of the liquidus generated in the aluminum alloy materials to the total mass of the aluminum alloy materials of the other joined member is ≤35%. There are provided the method for manufacturing the aluminum alloy joined body using the aluminum alloy materials joined thereby, and the aluminum alloy joined body manufactured thereby.;COPYRIGHT: (C)2013,JPO&INPIT
