Method of manufacturing or repairing a bladed rotor disc

摘要

The fabrication or repair of a solid bladed disc includes a stage of formation, on a flat turning contact (4) of a disc (1) and extending from one upstream end (4a) to a downstream end (4b) the length of a cord of the turning contact (6), of a surface of a weld joint (8) destined to allow an ulterior stage of assembly by linear friction welding of a blade (2) on the turning contact of the disc. The stage of formation of the surface of the weld joint is realized such that it includes at least two joining plane portions (8a, 8b, 8c), arranged successively along the cord of the turning contact. An independent claim is also included for a disc for a solid bladed disc incorporating a turning contact.
