Abstract (en)
[origin: CA2702435A1] The invention relates to a method for producing a blisk (bladed disk) or a bling (bladed ring) of a gas turbine, said method comprising the following steps: a) producing a turbine blade (10) by joining a blade (12) to an adapter element (16), consisting of a metal material that is suitable for fusion welding, said adapter element (16) being used to form a blade root of the turbine wheel (10), and b) joining the turbine wheel (10) to a rotor disk (22), consisting of a metal material that is suitable for fusion welding, or to a rotor ring, consisting of a metal material that is suitable for fusion welding, in such a manner that the turbine wheel (10) is arranged on the outer periphery (26) of the rotor disk (22) or of the rotor ring. The invention further relates to a component of a gas turbine or of a high-pressure or low-pressure compressor, especially to a blisk (bladed disk) or bling (bladed ring). According to the invention, the component (30) consists of separately produced turbine blades (10) or of an annular blade ring (28), separately produced from the turbine blades (10), and a rotor disk (22) connected thereto and consisting of a metal material that is suitable for fusion welding, or a rotor ring connected thereto and consisting of a metal material that is suitable for fusion welding, the turbine blades (10) or the blade ring (28) being arranged on the outer periphery (26) of the rotor disk (22) or of the rotor ring and the turbine blades (10) consisting of respective blades (12) and adapter elements (16), consisting of a metal material that is suitable for fusion welding, fastened thereto, and the adapter element (16) being configured to form a blade root of the turbine blade (10). The invention also relates to a novel turbine blade.
