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...
