Abstract:
1. A method of fabricating a cavitation chamber comprising the steps: a) mounting a piece of stock material in a first lathe chuck; b) finishing a first mating surface of a first spherical cavitation chamber half; c) turning an internal spherical surface corresponding to an inside surface of said first spherical cavitation chamber half; d) turning a first portion of an external surface of said first spherical cavitation chamber half; e) dismounting said piece of stock material and reversing a mounting position of said piece of stock material relative to a first lathe chuck position; f) mounting said piece of stock material in a second lathe chuck; g) turning a second portion of said external surface of said first spherical cavitation chamber half; h) repeating steps a) through g) with a second piece of stock material to form a second spherical cavitation chamber half, said second spherical cavitation chamber half having a second mating surface, both said first and second spherical cavitation chamber halves having a first inner diameter and a first outer diameter; i) aligning said first and second mating surfaces; and j) electron beam welding said first and second mating surfaces together using an electron beam.
