BIMETALLIC WIRE MANUFACTURING METHOD Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed method of manufacture of bimetallic wire includes feeding of core, wrapping of core in envelope and connecting of envelope edges, heating and rolling of blank. Prior to wrapping of core it is subjected to electrolytic plasma machining at anodic dissolution of electrode made of the same material as envelope. EFFECT: improved connection of core with envelope owing to formation of underlayer of metal of structure similar to that of envelope metal structure. 3 dwg
