An automated welding operation is applied to the liner. A coating of the liner on a cold side of the liner is retained on the liner during the welding operation.

Automated weld repair of combustor liners

An example method of repairing an airfoil includes the steps of securing additional material to a worn airfoil and limiting movement of the additional material with a guide. The method alters some of the additional material to form a desired airfoil contour. Another example method of forming a portion of an airfoil includes the steps of securing additional material to an airfoil, limiting movement of the additional material with a guide, and altering some of the additional material to form a desired airfoil contour.
