FIELD: metallurgy, namely production of bimetals or laminate structures. SUBSTANCE: process provides formation of bimetal or laminate structure by contact melting of joined metals, intermediate coatings or liners. Process comprises steps of approaching current leading electrodes to metals being in contact; placing holder with samples into thermostat; performing contact melting at temperature higher than eutectic temperature value by 1 K; passing direct electric current through contact; selecting current direction in such a way that to match diffusion flow in contact area with that of electric charge transfer; using alloys in liquid-solid phase as connecting liner. It is possible to change concentration of components of alloy of liner due to changing temperature of bimetal. Concentration values of components corresponding to temperature is taken from phase diagram. Process allows to increase rate of forming contact zone, to adjust its thickness. EFFECT: enhanced strength of bimetal. 2 cl, 3 dwg, 1 tbl, 2 ex
