    摘要: 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.

    摘要: An adaptive control hybrid welding system including hybrid welding apparatus, control system connected to hybrid welding apparatus, and seam tracker connected to control system is provided. Hybrid welding apparatus includes a laser and an electric arc welder. Laser and electric arc welder each have adjustable welding parameters. Control system modifies welding parameters of laser and electric arc welder, and spacing between laser beam and arc of welder. Seam tracker is operable to measure seam property of adjacent workpieces prior to welding. Seam tracker is operable to send signals to control system in response to the measured seam property. Control system modifies welding parameters based on signal from seam tracker and adaptive control hybrid welding apparatus joins adjacent workpieces having variable gap sizes of up to 2.5 mm with full penetration welds. Also provided is a method of controlling the adaptive control hybrid welding system.
