Abstract RU 2201320 C1

FIELD: welding by means of consumable or non-consumable electrode at feeding titanium base additive wire. SUBSTANCE: method comprises steps of preliminarily heating welding or additive wire in nitrogen atmosphere until temperature sufficient for forming on wire surface protective film of titanium nitride. It is possible to perform heating until temperature almost equal to temperature of melting wire material. EFFECT: significantly lowered porosity of welded seam metal. 2 cl
