FIELD: manufacture of shaped tubes and flat shaped articles of different steels and alloys. SUBSTANCE: method of making shaped tubes and flat shaped articles comprises steps of placing blank onto mandrel and deforming it by means of pulse energy action; setting inner perimeter of blank equal to outer perimeter of mandrel; creating pulse energy value sufficient for providing plastic deformation of portions of maximum change of blank profile. EFFECT: enhanced efficiency. 2 cl, 4 dwg
