摘要： 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.

摘要： A stub shaft section adapted to be welded to a re-used end portion of a rotor shaft, the stub shaft section including a hollow cylindrical member having a substantially uniform inner diameter and first chamfered end adapted to form one side of a substantially V-shaped weld groove, and an integral backing ring extending axially beyond the chamfered end, the backing ring having a circumferential recess in a radially outer surface thereof. A related method of replacing a stub shaft on an end of a rotor shaft comprising: (a) providing a new stub shaft with a first chamfered end and an integral backing ring; (b) aligning the first chamfered end with a second chamfered end on the rotor shaft, with the integral backing ring overlapping the second chamfered end, and with the first and second chamfered ends forming a substantially V-shaped weld groove, with the integral backing ring overlapping the second chamfered end; (c) filling the V-shaped groove with weld material; (d) welding the stub shaft to the rotor shaft; and (e) machining the integral backing ring away from the stub shaft.
