    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.

    摘要： Bucket tip tenons requiring refurbishment are removed from the bucket tips by grinding. Groups of buckets are clamped on a rotatable table in positions adjacent an induction heating coil and a robotic welding arm, respectively. While one group is preheated, the other group of buckets is in a welding location, enabling the welding head on the robotic arm to sequentially apply weld buildup material to the bucket tips. After applying weld buildup material in multiple passes and sequentially to the bucket tips, the buckets are removed, stress-relieved and the weld buildup material machined to provide refurbished tenons. Upon removal of the buckets from the table, the table is rotated to locate the preheated buckets in welding locations and additional buckets are clamped to the table for preheating.

    摘要翻译： 需要翻新的铲斗榫头通过磨削从铲斗顶部移除。 一组铲斗分别夹在与感应加热线圈和机器人焊接臂相邻的位置的可旋转工作台上。 当一组预热时，另一组铲斗处于焊接位置，使得机器臂上的焊接头能够将焊接积聚材料依次施加到铲斗顶端。 在多次通过中施加焊接成型材料并依次施加到铲斗前端之后，移除铲斗，减轻应力，并加工焊接成型材料以提供翻新的榫头。 从桌子上取下铲斗后，转动桌子将预热的铲斗定位在焊接位置，另外的铲斗被夹紧在工作台上进行预热。
