Abstract
Ultrasonic peening treatment is desirable where an application of a compressive stress is helpful to reduce the incidence of crack formation on highly stressed parts. Ultrasonic peening treatment can be performed in field applications without requiring a rotor to be removed from the machine. The system includes an acoustic element that excites peening media within a peen chamber. A frame is attachable to an assembled turbine rotor component and includes support structure engageable with the acoustic element. The frame is cooperable with a chamber tooling that defines and encloses the peen chamber together with the turbine rotor component.
