Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an integral backing ring machined to an end of a rotor or a stab shaft at a root, i.e., a base of a weld groove. SOLUTION: A stub shaft section (16) adapted to be welded to a re-used end portion of a rotor shaft (12), the stub shaft section includes a hollow cylindrical member having a substantially uniform inner diameter and first chamfered end (18) adapted to form one side of a substantially V-shaped weld groove (22), and an integral backing ring (20) extending axially beyond the chamfered end (18). The backing ring has a circumferential recess (28) in a radially outer surface (30) thereof. COPYRIGHT: (C)2007,JPO&INPIT
