PROCESS FOR ELECTRIC ARC SURFACING BY MEANS OF NON-CONSUMABLE ELECTRODE Russian patent published in 2006 - IPC B23K9/04 

FIELD: welding processes and equipment, possibly surfacing of blade surfaces.

SUBSTANCE: method comprises steps of placing welding torch by acute angle α_tor relative to surfaced plane; placing additive wire by acute angle α_wire relative to surfaced plane;_{feeding additive wire to zone of anode spot of welding electric arc behind torch along welding direction in order to reduce heat absorption of base metaland to decrease its fusion; igniting welding electric arc and creating welding bath; extending welding bath towards additive wire.}

EFFECT: increased height of surfaced bead at minimum fusion of blade surface during one pass.
