Abstract
A method of connecting a rotationally symmetrical part () having precision-machined functional surfaces () to a hub part () by welding is to deliver a distortion-free end product. To this end, the rotationally symmetrical part () and the hub part (), in their longitudinal sections, are dimensioned in such a way that, when the rotationally symmetrical part () is shrunk onto or pressed onto the hub part (), stresses are produced in the former and said stresses produce deformations which are opposed to the stresses to be expected during the subsequent welding and to deformations caused by said stresses. This is achieved by one of the contact surfaces () being conical or by shaping the rotationally symmetrical part ().
