FIELD: metallurgy.
SUBSTANCE: initial strips of gold and silver alloy, as well as solder strip, are obtained by continuous casting method. Rolling of gold strip and solder strip is performed in alternation with annealing. They are attached to each other by soldering and rolling with annealing of the obtained bimetallic workpiece is performed till the specified thickness is obtained. Rolling of initial silver strip is performed in turn with annealing till silver workpiece of the specified thickness is obtained. Then, nonoxidation diffusion soldering of the above gold workpieces with silver solder and rolling of the obtained bimetal is performed till the specified thickness is obtained.
EFFECT: method allows obtaining new types of two-layer and two-colour jewellery.
