BONDING OF ALUMINIUM PARTS BY BRAZING OPERATIONS Russian patent published in 2015 - IPC B23K1/00 B23K1/19 B23K103/10 

FIELD: process engineering.

SUBSTANCE: proposed process can be used for connection of aluminium parts by brazing, for example, in production of radio components. Parts are preliminary processed by nickel-, copper- and tin-zinc-plating. After assembly, brazing paste is applied over the perimeter of parts as a roller and said parts are heated to 120-160°C. Brazing is performed by air heated to 300-350°C. Cooled parts are flushed to remove flux residues.

EFFECT: higher quality, possibility of brazing the different-depth structures.
