Abstract
A method for manufacturing a vehicle wheel includes the steps of providing a wheel rim and a spider and positioning the wheel rim and the spider adjacent each other. The wheel rim and the spider are then friction welded to each other. Subsequently, a portion of the spider is locked down onto the wheel rim by electromagnetic forming. Preferably, one end of the rim is positioned in a cavity formed in the spider. During friction welding, the upset material of the rim fills the cavity of the spider. Subsequently, while the metal is still relatively fluid, a flange of the spider is locked down onto the wheel rim by electromagnetic forming to secure the wheel rim and spider together.
