Patent

CA 2716117

A method of making a fan (20) includes making a subassembly (48) comprising a backplate (22) and a plurality of blades (24) extending from the backplate (22), making a fan shroud (26), positioning the fan shroud (26) adjacent to the blades (24) of the subassembly (48), providing ferromagnetic particles at a first weld location, and directing electromagnetic energy toward the ferromagnetic particles at the first weld location to melt surrounding material and structurally join the fan shroud (26) and at least one of the blades (24).

L'invention porte sur un procédé de fabrication d'un ventilateur (20) qui comprend la fabrication d'un sous-ensemble (48) comprenant une plaque arrière (22) et une pluralité de pales (24) s'étendant à partir de la plaque arrière (22), la fabrication d'un carénage de ventilateur (26), le positionnement du carénage de ventilateur (26) adjacent aux pales (24) du sous-ensemble (48), la disposition de particules ferromagnétiques en un premier emplacement de soudure, et la direction d'une énergie électromagnétique vers les particules ferromagnétiques au premier emplacement de soudage pour faire fondre le matériau environnant et relier structurellement le carénage de ventilateur (26) et au moins l'une des pales (24).
