Method for producing rotationally symmetric parts

A process for the manufacture of rotationally symmetrical components made of a tube, in particular of hollow monobloc shaft, the tube initially has a constant outer diameter and a constant wall thickness and the rotationally symmetrical component, at least over a portion of its total length a deviating, smaller outer diameter and a deviating, greater wall thickness , having the following method steps: Using a welded, not redrawn tube with a wall thickness which corresponds to the smallest wall thickness of the finished component, partial heating at least a portion of the tube, axial upsetting of the heated region of the tube and radial forging of the heated region of the tube.
