Abstract
This invention relates to a process for manufacturing an axially symmetrical rotor adapted to rotate about the vertical axis thereof and having a length greater than the diameter thereof which comprises rolling a thin, high-strength steel sheet to form a cylinder having a longitudinally-extending joint, PA1 Welding said joint by electron beam welding, PA1 Solution-treating the blank thus formed, PA1 And bringing the blank to its final dimensions by means of the three-roll press rolling process wherein the blank mounted on a rotating pressure mandrel having a stop is pressed by pressure rollers moving toward the stop while the material of the blank flows counter-currently with respect thereto.
