FIELD: jewellery.
SUBSTANCE: invention can be used to manufacture chains from gold alloys by means of soldering. The method involves treatment of chains by rotation in the cartridges of four-unit vibration units a mixture of solder powder of size less than 150 mcm along with silica sand with size of more than 150 mcm with their mass relation of 1:1 follwed by soldering on conveyor electric resistance furnaces in the reducing gas atmosphere.
EFFECT: invention enables to obtain quality soldered joint of the chain links and eliminates complexities such as impurities of base components of the powder solder on the surface of links of the soldered chain that change a colour shade of the main metal and causing deterioration of the gold fineness.
