ABSTRACT:
Disclosed is a centrifugal-blower impeller, which consists of a center part and radially outer part, which has a smaller thickness of material than the center part. The outer part consists of ring segments attached by welding to the periphery of the center part. The ring segments are first welded to the center part and thereafter radially to each other so that the ring segments are subject to tensile stress and the center part to compressive stress.
