The invention relates to 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 (14) comprising a plurality of rotor blades (12), welding adapters (22) together which are disposed in the region of blade footings of the rotor blades (12), wherein at least substantially radial weld seams (30a) having predetermined welding depths are generated, disposing a rotor disk (32) or a rotor ring on the blade ring (14), and welding the rotor disk (32) or the rotor ring to the adapters (22) of the rotor blades (12), wherein at least one further weld seam (30b) is generated. The invention further relates to a rotor, particularly a turbine disk or a turbine ring for a turbine stage of a turbomachine.
Linvention concerne un procédé de fabrication dun rotor, en particulier dun disque de turbine ou dune bague de turbine pour un étage de turbine dune turbomachine, consistant à : former une couronne daubes (14) comprenant une pluralité daubes de rotor (12), souder ensemble des adaptateurs (22) agencés dans la zone des pieds daubes des aubes de rotor (12), au moins des cordons de soudure sensiblement radiaux (30a) étant réalisés à des profondeurs de soudure prédéterminées. Le procédé consiste également à agencer un disque de rotor (32) ou une bague de rotor sur la couronne daubes (14), et à souder le disque de rotor (32) ou la bague de rotor aux adaptateurs (22) des aubes de rotor (12), au moins un cordon de soudure supplémentaire (30b) étant réalisé. Linvention concerne également un rotor, en particulier un disque de turbine ou une bague de turbine pour un étage de turbine dune turbomachine.
