Abstract:
An impeller for a centrifugal machine includes a hub having at least one slot formed therein. A blade is mounted in the slot with the leading edge of the blade comprised of a relatively thin top section in contact with the fluid flowing through the machine, and a relatively thick bottom section for insertion into the slot. The blade is welded to the hub at the interface of said thick bottom section and the hub.
