摘要： A formed disc for use in a low pressure rotor has a rim made of a high alloy metal of between approximately 9% and 17% chromium. The rim can be annular in shape and slide onto the perimeter of an unformed disc for the two components to be fused together, thus fabricating a formed disc. Additionally, the rim can be split into a number of components and fused together on the perimeter of a rotor disc to form a complete rim. Further, an entire disc can be made out of the high alloy metal.

摘要： A low pressure steam turbine and generator low alloy steel disc rotors with extended useful life properties. A ring member of the disc rotor has disposed on it multiple weld layers of ferrous material, forming a weld region. The ring member is made of a low alloy ferrous metal alloy having less than about six weight percent alloying ingredients including chromium. The chromium content of the weld region increases overall from a portion of the weld region adjacent to the ring member to a portion of the weld region farthest from the ring member. This general increase is accomplished using weld metal of a single chromium concentration of between 9% and 17% chromium and varying the welding parameters.

摘要： The invention provides a blade-rotating device for rotating a plurality of radially-oriented blades having a blade base with two grooved base sides. The device has a portion, such as a disc or a rotor disc of a turbine, for rotating the blades with the portion having an outer cylindrical surface. The device also has a plurality of steel steeples each having a steeple base and two opposite grooved steeple sides extending therefrom. Each of the opposite steeple sides complements at least one of the grooved sides of at least one of the blade bases. The steeple bases are linear friction welded to the outer cylindrical surface in an approximately longitudinal direction such that the blade bases are engagable with the steel steeples.

摘要： A method of removing blades from the rotor of a turbo machine, such as a steam or gas turbine, in which material deposits formed between the surfaces of the blade root and its retaining groove have effectively bonded the blade root to the rotor groove. The blade root and groove are submersed in a liquid medium enclosed in a tank. Transducers installed on the tank radiate ultrasonic pressure waves into the liquid medium that breakup the material deposits through cavitation, thereby loosing the bond between the blade root and the groove. The blade is then removed from the tank and the blade slid out of the groove.

摘要： This invention relates to an improved method for repairing damaged or worn surfaces of turbine components or upgrading older designs to new, improved designs. This improved method applies to both high pressure and low pressure turbine components applications. This method includes depositing a plurality of individual spaced apart weld volumes onto a prepared surface of a turbine rotor. These individual spaced apart weld volumes form individual fingers without the need to machine the individual fingers from a single rectangular weld volume. Multiple weld volumes are formed concurrently with a space maintain between each weld volume using multiple torches without the problems normally associated with closely spaced welding arcs. Each individual spaced apart weld volume is formed by a plurality of layers of weld metal, with each layer being formed from a single oscillating weld bead to form a predetermined width. The filler wire may be heated by applying a current through the filler wire before it is fed into the weld pool. Welding parameters are also changed to increase the amount of weld deposition without adversely affecting the mechanical weld properties. The invention provides for reduced cycle time for repair work by using multiple torches simultaneously without causing arc instability. The invention also reduces cycle time, by eliminating the need of machining individual fingers on control stages from a single weld volume, by changing the weld buildup of multiple projections, slightly larger than the fingers which hold the blades.
摘要翻译：本发明涉及一种用于修复涡轮机部件的损坏或磨损表面或将旧设计升级为新的改进设计的改进方法。这种改进的方法适用于高压和低压涡轮机部件应用。该方法包括在涡轮转子的制备表面上沉积多个单独的间隔开的焊接体积。这些单独的间隔开的焊接体积形成单独的手指，而不需要将单个手指从单个矩形焊接体积加工。多个焊缝体积与使用多个焊炬的每个焊接体积之间的空间同时形成，而没有通常与紧密间隔的焊接弧相关联的问题。每个单独的间隔开的焊接体积由多个焊接金属层形成，每个层由单个振荡焊道形成以形成预定宽度。填充线可以在被送入焊池之前通过将填充线施加电流来加热。也改变焊接参数以增加焊接沉积的量，而不会不利地影响机械焊接性能。本发明通过同时使用多个割炬而减少了修理工作的周期时间，而不会导致电弧不稳定。本发明还通过改变比保持叶片的手指稍大的多个突起的焊缝积聚来消除从单个焊接体积加工单独手指在控制台上的需要，从而缩短了循环时间。

摘要： A welding process of repairing a ferrous NiMoV low alloy steel turbine component. A first and a second layer of weld material are welded to the turbine component at electrical current levels chosen so as to prevent a substantial decrease and a substantial increase in the hardness of the component. This method involves selecting these electrical current levels. Additionally, this invention relates to selecting appropriate electrical current levels that minimizes the difference between a maximum and a minimum level of hardness while welding a first and a second layer of weld material. This invention also includes a method for preventing a substantial decrease in the hardness of the component as a result of the welding process.
