The work presents the results of numerical modeling of thermal fields in the zone of joining aluminium plates through interlayers during local heating of the joint zone by a flat heater, contacting one of the plates. Layers consisting of braze alloy, multilayer reactive foil or layers of both types were considered as an interlayer. Calculation was carried out considering the thermal-physical characteristics of the material of plates, interlayer and heater, consisting of multilayer reactive foils, in which a reaction of self-propagating high-temperature synthesis is accompanied by intensive heat evolution. Conditions of local heating of the aluminium plates necessary for obtaining permanent joints during their brazing or welding through an interlayer were studied. 14 Ref., 1 Table, 11 Figures.
Keywords: brazing, welding, aluminium alloys, braze alloy, multilayer foil, thermal fields, local heating, permanent joint
