Abstract: A device and method for locally heat treating at least one airfoil in an integrally bladed rotor device. A pair of IR heat sources are positioned to direct IR heat rays in the direction where local heat treatment is required. A pair of parabolic minors are positioned to direct the IR heat rays on to the metal component. The heat treating is useful after welding the airfoil on to the rotor device.Figure 1

Abstract: An example method of attaching an airfoil for an integrally bladed rotorincludes placing a support collar in an installed position around at least a leading edge and trailing edge of an airfoil stub to be repaired in an integrally bladed rotor. The support collar and the airfoil stub together have a midline that is positioned between opposing, laterally outer surfaces of the airfoil stub when the support collar is in theinstalled position. The method performs linear friction welding to add a replacement airfoil to the airfoil stub.Figure 1

Abstract: Brazed structures (10) comprising hollow components (12) having a closure component (14) bonded thereto by a metallic brazing alloy (16) for closing off an end of the hollow component (12) are disassembled by locating a wire transport material (20) in the hollow component (12) and covering the open face of the hollow component with a wire fiber material (22). Heat is then applied to liquefy the brazing alloy (16) which is drawn up into the metal wire fiber material (22) by capillary affect created by the wire transport material (20).

Abstract: METHOD AND APPARATUS OF HEAT TREATING AN INTEGRALLY BLADED ROTORA process for heat treating selected portions of an integrally bladed rotor (IBR) having a plurality of blades, the process using an IBR on a fixture having a rotor engaging portion that moves the IBR into an environmental chamber. An IR heater is placed on one of the IBR blades and heat treated after air has been removed from the chamber and an inert gas is added. The IR heater is lifted from the blade and indexed to position another blade on the IBR. The process is repeated until all the IBR blades are heat treated.Fig. 1
