摘要： The present invention discloses various methods for repairing a side seal region of a transition duct aft frame region. Embodiments of the present invention include application of a braze filler material to worn locations of seal teeth, brazing of a braze preform to the seal teeth or removal of a worn seal tooth and brazing of material compatible with the transition duct to form a replacement tooth of the side seal. The transition duct is brazed in a furnace in an incremental heated process which elevates the transition duct to a temperature where the braze filler material adheres to the side seal region while also providing a stress relief to the transition duct.
