Abstract:
A method of weld repairing a nickel-base superalloy article having a nil-ductility range from a solidus temperature of the superalloy to about 600Â° F. below the solidus temperature, comprising the steps offurnishing the article made of the nickel-base superalloy having a nil-ductility range from the solidus temperature of the superalloy to about 600Â° F. below the solidus temperature, the article having a body with a near-surface defect near a surface thereof; providing a heat source having a heat source beam with a power level of no greater than about 5 amperes; weld repairing the near-surface defect, the step of weld repairing including the steps of locally melting the surface of the article in a region of the near-surface defect using the heat source to form a melted region, while not otherwise heating the body of the article, and thereafter allowing the melted region to solidify.
