CA 2708370
The invention relates to a method for producing and repairing a part comprising at least two joined metal components, especially components of a gas turbine. In said method, corresponding joining surfaces of the components are joined together and connected by means of a pressure welding process, a machining allowance in the area of a joining zone of the two joining surfaces is upset during the joining process, and once the two components have been joined together, the machining allowance is machined by means of a precise electrochemical machining (PECM) process until a predefined final contour of the part has been obtained. The invention further relates to a gas turbine part obtained by means of the disclosed method.
L'invention concerne un procédé de production et de réparation d'un composant comprenant au moins deux éléments métalliques assemblés entre eux, en particulier des éléments d'une turbine à gaz, l'assemblage et la liaison des surfaces correspondantes desdits éléments s'effectuant par soudage par pression. Une surépaisseur est refoulée dans la région d'une zone d'assemblage des deux surfaces à lier et, après assemblage des deux éléments, on procède à un usinage de la surépaisseur par érosion électrochimique précise (PECM), jusqu'à obtention d'un profil définitif prédéfini du composant. L'invention concerne en outre un composant d'une turbine à gaz fabriqué conformément au procédé de l'invention.
