Abstract
A process for manufacturing a wheel for a motor vehicle, in which a wheel spider and a rim ring are connected with one another by means of friction welding. At least one of these wheel parts consists of a magnesium alloy. The controlling of the speed of the start of the friction, of the friction and of the compression of the friction welding process, particularly of the deformation capacity, takes place as a function of physical characteristics of the magnesium alloy.
