BIMETAL ELECTRODE WIRE, METHOD OF PRODUCING BIMETAL ELECTRODE WIRE AND DEVICE TO THIS END Russian patent published in 2011 - IPC B23K35/40 B21F15/00 

FIELD: process engineering.

SUBSTANCE: invention may be used in production of wire intended for metal deposition for hardening purposes. Wire core is made from central aluminium conductor 1 enveloped by nickel conductors 2 of the same diametre arranged in contact and symmetry about the former. Nickel conductors stay in contact to form air spaces 3. Wire core is arranged in solid aluminium shell 4. In producing said wire, the core is transferred through the device working chamber whereto heated aluminium billet is fed to be compacted to aluminium yield state.

EFFECT: higher quality of bimetal electrode wire, simplified device and control procedure for producing bimetal electrode wire.
