A method for producing a rotor, particularly a turbine disk or a turbine ring for a turbine stage of a turbomachine, wherein at least the following steps are carried out: producing a blade ring () including a plurality of rotor blades (), welding adapters () together which are disposed in the region of blade footings of the rotor blades (), wherein at least substantially radial weld seams () having predetermined welding depths are generated, disposing a rotor disk () or a rotor ring on the blade ring (), and welding the rotor disk () or the rotor ring to the adapters () of the rotor blades (), wherein at least one further weld seam () is generated. A rotor, particularly a turbine disk or a turbine ring for a turbine stage of a turbomachine is also disclosed.

Method for the production of a rotor and rotor

The invention relates to a method for manufacturing an integrally bladed rotor, whereby several rotating blades are attached to a basic rotor body by welding in such a way that first, grooves into which the rotating blades are introduced by their blade feet or adapters, and which extend substantially in the axial direction of the basic rotor body, are introduced into the basic rotor body radially outside, prior to attaching the rotating blades, then, the rotating blades are welded to the basic rotor body, wherein the grooves are introduced in the rotor body and the blade feet or adapters are formed on the rotating blades in such a way that a central axis of the grooves is positioned obliquely relative to a central axis of the blade feet or the adapters, so that a pre-twisting is formed on the rotating blades when the rotating blades are introduced into the groove.
