    Abstract: PROBLEM TO BE SOLVED: To provide a method for repairing parts such as a rotary disc/ drumrotor of a gas turbine engine. SOLUTION: This method includes steps for: heating a contact area 207 of a forged material and a contact area 307 of forged parts; pressurizing the contact area 207 of the material to the contact area 307 of the parts to joint them. A method for producing rotary parts of the gas turbine engine includes a step for heading the contact area 207 of the forged material and the contact area 307 of the forged parts, and a step for pressurizing the contact area 207 of the material to the contact area 307 of the parts to joint them. This method may include a sequential heat treatment step for giving a desired strength characteristic to a joint part 309 between the material and the parts. COPYRIGHT: (C)2003,JPO

    Abstract: SYSTEMS AND METHODS FOR PROVIDING LOCALIZED HEAT TREATMENT OF METAL COMPONENTS Systems and methods for providing localized heat treatment of metal components are provided. In this regard, a representative method includes: identifying a portion of a metal component to which localized heat treatment is to be performed; shielding an area in a vicinity of the portion of the metal component; and directing electromagnetic energy in the infrared (IR) spectrum toward the portion of the metal component such that the portion is heated to a desired temperature and such that the area in the vicinity of the portion that is subjected to shielding does not heat to the temperature desired for the heat treatment.

    Abstract: METHOD OF JOINING MATERIAL A method of repairing a part, such as a rotating disk/drum rotor of a gas turbine engine. The method includes: heating a contact area of a wrought material and a contact area of a wrought part; and pressing the contact area of the material against the contact area of the part to bond the parts. A method of making a rotating part of a gas turbine engine, comprising: heating a contact area of a wrought material and a contact area of a wrought part; and pressing the contact area of the material against the contact area of the part to bond the parts. The methods may include a subsequent heat treatment to provide the desired strength properties to the joint between the material and the part. Figures 6 and 7

    Abstract: SYSTEMS AND METHODS FOR PROVIDING LOCALIZED HEAT TREATMENT OF GAS TURBINE COMPONENTS Systems and methods for providing localized heat treatment of gas turbine components are provided. In this regard, an exemplary method includes: identifying an area of a gas turbine component to which localized heat treatment is to be performed; positioning a resistance heating element, sized and shaped to transfer heat to the area, adjacent the area; electrically coupling a current-limiting power controller to the resistance heating element; and locally heating the area using the resistance heating element, with power being provided to the resistance heating element via the current- limiting power controller.
