Abstract: Aspects of the disclosure are directed to repairing or restoring a liner associated with a combustor of an aircraft engine. The liner is at least partially stripped of at least one detail. 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.

Abstract: 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.

Abstract: Apparatus, method, and a kit for a yieldable tendon mine support rock anchor include structure and/or steps including the provision of a metal support member having an outside diameter which is less than a diameter of the rock hole. Preferably, resin cartridges are disposed inside the rock hole. A wedge anchor is provided and is disposed at a distal end of the metal support member and has a narrow portion disposed uphole from a wider base portion thereof. The wedge anchor base portion is narrower than the diameter of the rock hole to permit un-solidified resin to pass from downhole to uphole of the wedge anchor base portion. The wedge anchor is dimensioned to crush solidified uphole resin and permit downhole movement of the crushed solidified resin when a yielding tension is applied to the metal support member and the wedge anchor moves uphole.
