  • Turbine blade repair
    Patent number: 4611744
    Abstract: A method of repairing turbine blades including a repair step which involves the application of substantial thermal energy to the blade such as a welding or brazing operation includes a pre-heating step in which the blade is heated to a predetermined temperature in a controlled manner. The controlled heating may be continued both during the repair step involving the application of substantial thermal energy and after the repair step in order to minimize stress in the blade due to the application of considerable thermal energy to the blade.
