  • Vibration stress relief of superalloy components
    Publication number: 20060283920
    Abstract: A method of conditioning and stress relief for superalloy components includes vibrating the component during welding at a subharmonic frequency. The proper frequency is selected to be below a harmonic frequency, and to produce an amplitude in the range of ? to ½ the amplitude produced by a harmonic frequency. The component to be repaired is vibrated during and after welding at this frequency.
