ABSTRACT:
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.
