FIELD: tube production, possibly manufacture of thin-wall and super-thin wall tubes of refractory dispersion hardened nickel-base alloys.
SUBSTANCE: method comprises steps of continuously feeding formed tube blank and welding its edges in chamber filled with inert gas and simultaneously supplying inert gas into jet of torch and inside welded tube; after welding providing accelerated cooling of tube until 200-300°C in inert gas atmosphere.
EFFECT: enhanced mechanical strength of tubes due to improved quality of welded seam.
