FIELD: welding of articles. SUBSTANCE: invention refers to process of welding of two ends of metal articles, predominantly, tubes with use of special welding wire and special power supply source. It can find use in manufacture of tubes. Welding wire employed in the process contains, per cent by mass: carbon 0.06-0,15; magnesium 0.90-1.40 and silicon 0.45-0.75 as well as phosphorus, copper, alloying elements of stainless steel and sulfur. Content of sulfur in selected wire is kept at specified level in range from 0.015 to 0.035 per cent by mass and of phosphorus at level under 0.015 per cent by mass. Welding current with controlled form of wave of welding cycles with short-circuits is used in welding process. EFFECT: high quality of welds in open clearance. 16 cl, 4 dwg
