FAN MANUFACTURING AND ASSEMBLY

摘要

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).
