摘要： A method for repairing a degraded bolt hole in a casing flange by reaming and removing at least some corrosion on an inside and around the hole to form a reamed hole, mounting the flange to float relative to upper and lower electrodes of a welding machine, radially and axially clamping an area of the flange surrounding the reamed hole, placing upper and lower filler slugs in the reamed hole, placing the electrodes against upper and lower filler slugs and applying a welding current through the electrodes while applying pressure to the filler slugs with the electrodes and resistively heating and melting the filler slugs to form a weldment, and pulsing the welding current on and off. Pulsing may be performed with progressively increasing amounts of current. In situ tempering under the pressure of the electrodes may be performed on a substantially liquid pool formed by the welding current.

摘要： A method for bonding airfoil sections includes aligning upper and stub airfoil sections having upper airfoil pressure and suction sides and stub airfoil pressure and suction sides respectively, pressing together upper and stub airfoil cross sections at upper and stub airfoil distal ends of the upper and stub airfoil sections respectively, and then resistance welding, preferably solid state resistance welding, the upper and stub airfoil sections together along the upper and stub airfoil cross sections by passing electrical current across the upper and stub airfoil cross sections. The upper and stub airfoil sections may be clamped between pressure and suction side upper airfoil electrodes and between the stub airfoil pressure and suction sides respectively. The method may be performed while the stub airfoil section is attached to an airfoil carrier such as a rotor disk rim, a gas turbine engine drum, or a gas turbine engine blade platform.

摘要： A method for repairing defects in a substrate including the steps of placing a consumable filler slug in contact with the substrate in the vicinity of the defect; placing at least one electrically conductive cover sheet in contact with a portion of the consumable filler slug; bringing a first electrode and a second electrode in contact with the at least one cover sheet and applying a force; and transmitting electrical current between the electrodes, thereby resistively heating the at least one cover sheet and conductively heating the consumable slug and a portion of the substrate resulting in coalescence in a substantially liquid pool that fills the defect. The pool is then cooled to solidification under pressure. Alternative embodiments eliminate the need for the conductive cover sheet(s) by utilizing electrodes having increased electrical and thermal resistance. The consumable slug may be formed as a single unit or multiple sections, and may incorporate sacrificial retainers.

摘要： A hollow component for gas turbine engine, for example an outlet guide vane, is assembled from a body having at recessed pocket formed therein, and an aerodynamic cover bonded over the pocket. Both the cover and the body are constructed from materials which are not readily fusion weldable. The cover is attached to the body by a solid state bonding process, for example friction stir welding. The hollow component may also be built up from multiple individual components which are bonded to each other by a solid state bonding process such as friction stir welding.
