Method of manufacturing or repairing a bladed rotor disc

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 ulterio...

Zusammenfassung:	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. L'invention se rapporte à un procédé de fabrication ou de réparation d'un disque aubagé monobloc comprenant une étape de formation, sur un plot dépassant (4) appartenant à un disque (1) et s'étendant d'une extrémité amont (4a) à une extrémité aval (4b) le long d'une corde de plot dépassant (6), d'une surface de joint de soudure (8) destinée à permettre une étape ultérieure d'assemblage par soudage par friction linéaire d'une pale (2) sur le plot dépassant (4) du disque (1). Selon l'invention, l'étape de formation de la surface de joint de soudure (8) est réalisée de sorte que celle-ci comprenne au moins deux portions planes jointives (8a,8b,8c), agencées successivement le long de la corde de plot dépassant (6). Application aux rotors de turbomachines.
