DEVICE FOR ELECTROSLAG HIGH-ALLOY STEEL HARD-FACING Russian patent published in 2012 - IPC B23K25/00 

FIELD: process engineering.

SUBSTANCE: proposed device may be used for reconditioning workout machine parts and producing tools. Crystalliser 1 is arranged on support plate 7 to form built-up metal. Added part 6 makes the bottom of said crystalliser. Mechanism 3 for feeding electrode wore 2 into crystalliser 1 serves to displace vertically electrode wire and to feed current thereto from power supply. Crystalliser vibrator is arranged under it on base 5 to oscillate in horizontal and vertical planes to drive crystalliser axis along conical surface. Said vibrator comprises motor 9, cam 10 and, at least, three springs rigidly secured on base 5 by their lower ends and their upper ends on support plate 7.

EFFECT: constant hardness and strength of added metal due to uniform distribution of tungsten, decreased tungsten consumption.
