成果简介	NOVELTY - Invention relates to production of longitudinal electric-welded pipes. A longitudinal process seam is formed on the formed tubular billet by means of welding with high-frequency currents. Pipe billet with formed process seam is calibrated. Continuously moving tubular billet is cut to measured lengths. Longitudinal seams are formed on inner and outer sides of pipes cut into measured lengths by means of electric arc welding under flux. USE - Welding. ADVANTAGE - As a result, the weld impact strength is improved. 3 cl, 2 dwg
