Patent number: 11135677Abstract: Methods of repair of a component or adding material to a component using laser welding are disclosed. One method may include repairing or adding material to the component by laser irradiating a wire material with a laser in an inert gas in a vicinity of the component. The laser irradiating the wire material includes modulated pulsing the laser through: a warm up phase during which an on-power of the laser is increased over time to a maximum target on-power, a melt and bond phase during which the wire material is melted and during which the on-power is less than the maximum target on-power, and a stress releasing phase during which the on-power of the laser is less than the on-power during the melt and bond phase. The laser irradiated wire material forms a weld material to repair a damaged area or add material to the component.Type: GrantFiled: March 6, 2018Date of Patent: October 5, 2021Assignee: General Electric CompanyInventors: Fabrizio Mangano, Piero-Daniele Grasso, Norbert Lucke, Michael Seemann
