Abstract
A method for fabricating a rotor shaft using a welding process. The method includes positioning a first rotor shaft section adjacent a second rotor shaft section, and using a submerged arc welding process with an included weld preparation angle of between about 0° and about 30° to join the first and second rotor shaft sections together.
