Abstract

Procédé d’assemblage de pièces métalliques de massivités différentes et d iffuseur centrifuge réalisé avec ce procédé L’invention concerne un procédé d’assemblage d’une première pièce métallique (21) sur une seconde pièce métallique (22), la première et la seconde pièces métalliques comportant des massivités différentes, le procédé comportant les opérations : a) réalisation (110), sur une surface de la première pièce métallique (22), d’une fente (23),b) positionnement (120) de la seconde pièce métallique (22) au droit de la fente (23) de la première pièce métallique, etc) soudage (130), à travers la fente (23), de la seconde pièce métallique (22) sur la première pièce métallique (21) avec un faisceau de soudage à forte énergie, la fente assurant le guidage du faisceau de soudage. L’invention concerne aussi un diffuseur centrifuge pour turbomachine comportant un couvercle métallique (21) et une pluralité de pales métalliques (22), chaque pale (22) étant assemblée avec le couvercle (21) au moyen du procédé ci-dessus.
