<p>The apparatus and repair method allows new material to be welded to damaged component pieces using linear friction welding. The method involves, first cutting or machining the damaged portion of the work pieces to form a repair area. The repair area is machined to have a uniform concave repair weld surface. Next, a mating repair block or plug is produced or machined, which will provide the new material to replace the damaged material removed from the damaged work piece. The repair plug is formed or machined to have a convex weld surface, which mates to the concave weld surface of the work piece. A linear friction weld machine bonds the repair plug to the work piece within the repair area by vibrating the repair plug against the work piece under an initial weld pressure, which plasticizes the weld surfaces.</p> |
