Zusammenfassung: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 (152) with a laser in an inert gas (162) in a vicinity of the component. The laser irradiating the wire material (152) 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 (152) 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 (152) forms a weld material (150, 152, 350) to repair a damaged area (130) or add material to the component.
