摘要： A method of repairing a turbine rotor wheel having a damaged dovetail includes removing the damaged dovetail from the turbine wheel, leaving a turbine wheel body and welding a ring about the turbine wheel body in place of the removed damaged dovetail. During the welding process, including during preheating, welding or stress relieving, the temperature of the wheel body and ring is differentially controlled to introduce residual stresses in the ring. After welding a dovetail is formed in the ring for receiving turbine bucket dovetails. As a result, the ring has residual compressive stresses in a cold condition of the turbine whereby reduced net stresses in the ring in the location of the new dovetail during hot turbine operating conditions are reduced.

摘要： The broach assembly includes alternate spacers and cutters arranged in a sub-assembly having a lead at a leading end and a lag at a trailing end. The cutters have side margins in excess of the margins of the spacers for cutting material from the dovetail slots of the turbine wheel as the broach assembly passes through the slots. The bottom or apices of each spacer and cutter are tapered to form a continuously tapered surface along the bottom of the broach assembly. Upon passing the broach assembly through the slot, the assembly is progressively displaced in a radial outward direction to progressively cut the active dovetail slot surfaces. Shims may be disposed in the bottom of the slot to further displace the broach assembly radially outwardly in multiple passes.

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： A method for repairing the rim of a steam turbine rotor, and a weld material for repairing such rotors. The method generally includes the steps of removing a damaged rim and its associated dovetail region, so as to form a surface at the perimeter of the rim portion. A weld repair region is then formed on the surface, which is machined to reconstruct the rim portion and the dovetail region exclusively with the weld repair region. Thereafter, an appropriately configured blade is secured to the rim portion with the dovetail region. The method is particularly intended for the repair of a steel alloy rotor, such as a NiCrMoV, NiMoV and CrMoV alloy, while the weld repair is formed with a nickel-base superalloy whose mechanical and thermal properties are compatible with the repair method and the steel alloy over a broad temperature range.
