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： The temporary fastening system for joining upper and lower shell casings of a turbine to one another for maintenance purposes includes a stud/nut tensioning system employed in lieu of the conventional studs and nuts. Once the turbine is opened up and the inner shell and rotor removed, the upper and lower shell casings are temporarily secured to one another using studs received in registering openings in the horizontal flanges of the upper and lower shell casings and retainer plates serving as a stop for the stud/nut tensioning system. The tensioning system is hydraulically operated and avoids torsional force on the temporary studs. Once measurements are made, the turbine is again reopened and reassembled using the initially removed bolts or a third set of bolts to secure the upper and lower shell casings to one another.

摘要： Bucket tips and covers for the bucket tips are robotically welded to one another. Profiles of the bucket tips are patterned on the covers and openings generally corresponding to those profiles are formed through the covers. The openings may be stepped to limit the penetration of the bucket tip into the cover and the weld material is robotically applied to fill the remainder of the cover opening unoccupied by the bucket tip. Alternatively, the bucket tips may have a shoulder to limit penetration of the bucket tips in the cover openings. The weld is then stress relieved and machined to form a continuous smooth outer surface.
摘要翻译：铲斗前端的斗尖和盖子彼此自动焊接。铲斗顶端的轮廓图案化在盖和开口上，通常对应于通过盖形成的轮廓。开口可以是阶梯式的，以限制铲斗前端到盖中的穿透，并且焊接材料被机械地施加以填充由铲斗前端未占据的盖开口的剩余部分。或者，铲斗前端可以具有肩部以限制铲斗前端在盖开口中的穿透。然后对焊缝进行应力消除和加工，以形成连续光滑的外表面。

摘要： A system and method for easily separating upper and lower turbine shells involves forming elongated access pockets vertically aligned across the upper and lower turbine shells and at multiple locations on the turbine shells. Telescoping hydraulic rams are placed into elongated access pockets at each of the multiple locations for lifting the upper shell off of the lower shell. The telescoping hydraulic rams are connected to a controller for controlling each of the rams to operate in parallel with the other rams. Once the turbine shells are separated the upper turbine shell can be removed by conventional block and rigging.

摘要： Partitions have an airfoil coupled at opposite ends to inner and outer side walls. The side walls each mount radially extending male dovetails. The inner web and outer ring of a diaphragm include complementary shaped dovetail grooves. The male dovetails have a reduced diameter portions while the female grooves similarly have corresponding reduced diameter groove portions. The male dovetails are inserted into the female dovetail grooves in an aft direction with stops of the reduced male and female dovetails preventing further movement aft. Seal welds are applied to prevent forward movement of the partitions relative to the web and outer ring.
