FIELD: technological processes.
SUBSTANCE: between soldered surfaces material for soldering is placed in the form of foil from aluminium or its alloys that are not solders, with thickness of 5-50 micrometer, with composition on the basis of fluorine-aluminate flux applied on it on one or both sides, with thickness of layer of 5-50 micrometer. Assembly is heated until foil melts with formation of melted silumin and flux layer between soldered surfaces.
EFFECT: invention allows to simplify preparation for soldering of material made of aluminium or its alloys and to increase quality of soldering.
