FIELD: welding technique. SUBSTANCE: shielding gas is fed in one direction with welding wire in the course of welding, thus excluding drip transfer of material of filling wire to weldpool and consequently excluding spatter losses. Filling wire is fed directly to weldpool where it is molten together with parent metal. EFFECT: high fatigue strength of welds, enhanced reliability of welds in operation and reduced consumption of metal. 1 dwg
