ABSTRACT:
A method of manufacturing a turbofan, which facilitates a manufacturing process and reduces a defective fraction of products during the manufacturing process by providing joining portions of the turbofan with corresponding plane surfaces. The turbofan includes a rotating plate coupled at a center thereof to a shaft of a drive motor, a plurality of blades radially arranged on a peripheral area of a front face of the rotating plate, and a ring-shaped shroud coupled to front ends of the plurality of blades. The method includes forming the ring-shaped shroud and first parts of the plurality of blades integrally, forming the rotating plate and remaining second parts of the plurality of blades integrally, and joining the first parts to corresponding second parts by fusion bonding.
