Abstract
An apparatus and a process for producing a shrouded centrifugal impeller where a rear hub opening is machined into the stock material so that hard to reach surfaces in the enclosed passages can be machined. When the hard to reach passages are machined to a final stage, the rear hub opening is closed using a process such as electron beam melting or electron beam welding to enclose the passages and form a single piece shrouded impeller.
