Abstract
A rod-shaped heating element with a tubular carrier element attached to a cylindrical carrier ring and to the rod-shaped heating element using a magnetic forming process, the carrier ring and the rod-shaped heating element being within the tubular carrier element with the outer circumferential surface of the carrier ring contacting the inner circumferential surface of the tubular carrier element. As a result of the parts having been joined by magnetic forming, they are in a plastically deformed state which is free of thermal treatment effects and scuffing.
