Patent

CA 2645725

The invention relates to a method and a device (10) for joining at least one rotor blade (12) or at least one part of such a rotor blade (12) with a rotor support (14) of a gas turbine, especially a blade connection (16) of the rotor carrier (14), corresponding welding surfaces (20, 22) of the rotor blade (12), the rotor blade part, the rotor support (14) or the rotor blade connection (16) of the rotor support (14) being joined by inductive HF pressure welding. The at least one rotor blade (12) or rotor blade part is automatically supplied from at least one rotor blade and/or rotor blade part reservoir. The rotor support (14) is automatically positioned in such a manner that the welding surfaces (20, 22) to be joined are aligned in an exact position in relation to each other for the purpose of joining them.

La présente invention concerne un procédé et un dispositif (10) qui servent à relier au moins une ailette (12) ou au moins une partie d'une ailette (12) à un support de rotor (14) d'une turbine à gaz, en particulier une partie de connexion d'ailette (16) du support de rotor (14), la liaison entre les surfaces de liaison (20, 22) correspondantes de l'ailette (12), de la partie d'ailette, du support de rotor (14) ou de la partie de connexion d'ailette (16) du support de rotor (14) s'effectuant au moyen d'un soudage par pression haute fréquence inductif. Selon l'invention, l'amenée de l'ailette ou des ailettes (12) ou de la partie ou des parties d'ailette s'effectue automatiquement depuis au moins un réservoir d'ailettes et/ou de parties d'ailette, et le support de rotor (14) subit en outre un positionnement automatique de sorte que les surfaces de liaison (20, 22) à assembler sont positionnées avec exactitude l'une par rapport à l'autre pour permettre la mise en oeuvre du processus de soudage.
