The invention relates to the field of metal forming, in particular to the technology of obtaining electric-welded longitudinal cold-deformed shaped tubes of general purpose from carbon steel of small and medium size. In a method of manufacturing shaped tubes shaping of a circular cylindrical tube in stands of a forming mill at its continuous moving in an electric welding tube-forming sheet mill is simultaneously combined with sequential molding along the longitudinal axis of tube of zones of increased stiffness. To do this in the appropriate drive and idle stands of molding mill designed and manufactured rolls are used with additional relief elements for shaping on a workpiece of longitudinal corrugations, grooves or slots with calculation of required changes in the geometry of the profile of rolls. The invention provides high quality of products and output, improving the performance of electric welding tube-forming mill, expanding the range of shaped tubes and sizes, long-term performance of profiling rolls.
