Abstract
A process for modifying or repairing a metallic component, such as a combustion cap effusion plate for a gas turbine, is disclosed. The method includes generating a notch or groove in the metallic component and depositing a filler material in the notch or groove. A pulsed laser is applied to the filler material. The pulsed laser has a power, frequency, and pulse width sufficient to apply heat to the metallic component and to the filler material to make at least a portion of the metallic component and the filler material melt in order to weld the filler material to the metallic component and repair or modify the metallic component. Various operating parameters of the pulsed laser can be configured to reduce undesirable heating affects.
