Method for closing a hole in a metal article

Abstract:

A method for closing a hole penetrating a hole height from a first surface of a metal article through a second surface of the metal article is disclosed including removing a portion of the metal article surrounding the hole from the metal article. The portion includes a depth extending from the first surface into the metal article and terminating prior to the second surface. Removing the portion forms a support surface within the hole adjacent and opposite to the second surface. A metal support structure is disposed within the hole on the support surface, and a metal composition is applied into the hole and onto the metal support structure. The metal support structure, the metal composition, and the metal article are fused together.
