FIELD: mechanical engineering. SUBSTANCE: invention aims at improving quality of restoring tubular objects owing to reduced barrelness, formation of valleys on the surface of object, etc. When current passes through inducting wireway in the object clasped between end holders, currents are inducted. Inducting wireway consists of segments arranged at angle 90 deg. to each other, so inducted circular currents lye in two mutually perpendicular planes and direction of circular currents in one of them coincides with direction of generatrices of cylindrical surface of object. Such arrangement of circular currents results in more uniform heating of object and therefore in higher quality of restoration. EFFECT: improved restoration quality. 2 cl, 2 dwg
