Abstract
A method of restoring a gas turbine engine component includes removing a defect section of a turbine engine component according to a template. The template has a standardized shape and is used in a standardized location on the turbine engine component. The template is produced based upon common defect sections from other turbine engine components. A laser cladding is used to build a replacement section in place of the defect section. Thus, the turbine engine component is restored to near its original shape.

A method of restoring a gas turbine engine component, including the steps of:
- (a) determining a standard repair section based upon a plurality of test turbine engine components;
- (b) removing a section of a used turbine engine component that corresponds to the standard repair section;
- and
- (c) depositing a laser cladding on the used turbine engine component to produce a replacement section in the location of the removed section of step (b).
A method of restoring a gas turbine engine component, including the steps of:
- (a) removing a section of a turbine engine component, wherein the section corresponds to a predetermined template;
- and
- (b) depositing a laser cladding on the turbine engine component to produce a replacement section in the location of the removed section of step (a).
A gas turbine engine assembly comprising:
- a turbine engine component having a laser cladding replacement section with a standard feature at least partially established by a defect location on a different turbine engine component.
