    摘要: A turbine induction temper system. In one embodiment, an induction temper system for a turbine includes: an induction member; a control system operably connected to the induction coil; and a temperature sensor operably connected with the control system, wherein the control system is configured to control an electrical current supplied induction member in response to a temperature indicator about a component of the turbine obtained from the temperature sensor.

    摘要: A method for weld repairing an article formed of a low-alloy steel, such as a steam turbine component. The method generally includes the step of depositing a first weld repair (14) on a surface of the article, during which a hard heat-affected zone (HAZ) (18) having a fine grain size is formed in the article beneath the surface on which the weld repair (14) is deposited. The first weld repair (14) and at least a portion of the HAZ (18) adjacent the first weld repair (14) are then locally heat treated at a temperature above a critical temperature A.sub.1 of the alloy from which the article is formed. As a result of this localized heat treatment, the original grain structures of the first weld repair (14) and the HAZ (18) are entirely replaced with a fine-grain structure with acceptable hardness. Thereafter, at least one additional weld repair layer (16) is deposited on the first weld repair (14). The first weld repair (14) is intentionally formed to have a sufficient thickness to avoid formation of additional HAZ in the surface of the article as the additional weld repair layer (16) is deposited. Without a post-weld heat treatment of the additional weld repair layer (16) or the article as a whole, the method yields a repair weld (12) that exhibits properties that are comparable to and can even exceed that of the base material (10) of the article.

    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 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.

    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.
