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

摘要

The present invention provides 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. 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.
