Hybrid welding repair of gas turbine superalloy components
Methods are provided for repairing a degraded section of a turbine blade (100), the turbine blade (100) comprising a base material. In one embodiment, and by way of example only, the method includes the step of electro-spark depositing (408) a first material on the turbine blade degraded section to...

| description | Methods are provided for repairing a degraded section of a turbine blade (100), the turbine blade (100) comprising a base material. In one embodiment, and by way of example only, the method includes the step of electro-spark depositing (408) a first material on the turbine blade degraded section to form an intermediate layer thereon, the first material comprising a material that is substantially similar to the base material. Next, a second material is laser welded (410) onto the intermediate layer to form a repaired section. This invention combines the low-heat input of electro-spark deposition with the high welding quality and high deposition rate of laser powder fusion welding. |
