BONDING METHOD FOR ALUMINIUM MEMBERS, AND ALUMINIUM STRUCTURE BONDED BY MEANS OF SAID BONDING METHOD

摘要

[PROBLEM] Provided are an easy bonding method for aluminium members which does not require melted material or solder, and an aluminium structure which has sufficient strength without having a concentration of stress in a joint section. [SOLUTION] A joining method in which at least one among a first and a second aluminium member is bonded at a temperature at which the ratio of the mass of a liquid phase generated in the aluminium member, relative to the total mass thereof, is 5-35%, wherein the bond width of the bond part between the first and second aluminium members is greater than the minimum width of a cross-section of the body section of the second aluminium member, across a surface which is parallel to the bond surface between the first and second aluminium members. Also provided is an aluminium structure bonded by means of the method.
