Beschreibung
Zusammenfassung:	The method (100) involves applying (110) an adhesive between an intermediate manufacturing element i.e. disk, and a fan blade. The manufacturing element is positioned (120) on the fan blade. Heat treatment of the adhesive is locally carried out (130) at a temperature and a pressure by a heater for polymerizing the adhesive and fixing the manufacturing element on the fan blade. The heater is provided with jaws for fixing to the manufacturing element and/or to the fan blade. The manufacturing element is maintained in position on the fan blade by the heater during polymerizing the adhesive. L'invention concerne un procédé de fabrication (100) d'une pièce de turbomachine, notamment d'une aube de soufflante d'une turbomachine, l'aube (1) comprenant une partie sur laquelle est rapporté au moins un élément intermédiaire de fabrication (20), le procédé (100) étant caractérisé en ce qu'il comprend les étapes suivantes : - appliquer (110) de la colle entre l'élément intermédiaire de fabrication (20) et la partie, - positionner (120) l'élément intermédiaire de fabrication (20) sur la partie, et - effectuer localement un traitement thermique (130) de la colle à une température et une pression données de manière à polymériser la colle et fixer l'élément intermédiaire de fabrication (20) sur la partie.
