Abstract
A method for repairing a blade tip of a turbine blade based on a dual fusion weld process for portions of a tip plate and a mechanical locking bead over the tip plate. A damaged portion of blade is removed. The damaged portion is removed at an initial cut level. An undamaged portion of the turbine blade exists as a base below the initial cut level. A replacement section is rebuilt via laser cladding. The replacement section is machined to form a tip pocket. A tip plate is placed in the tip pocket. The tip plate comprises at least a first portion and a second portion. The tip plate is welded using a dual fusion weld process comprising a first weld process and a second weld process. A squealer tip is built using a welding process that forms a mechanical locking bead over the tip plate.
