An integral aft seal for sealing the interface between a gas turbine transition piece and first stage nozzle exhibits sufficient variable thickness to adjust for relative component movement. The seal comprises a contiguous material having opposing planar faces and stiffeners attached at each of the faces. The contiguous material has corrugations to provide variable thickness. The stiffeners are attached to the planar faces of the contiguous material and generally have the same planar shape as the seal. Flexibility in the thickness dimension due to the corrugations biases the stiffeners away from one another and into contact with the turbine components. The aft seal is affixed to the transition piece by an attachment structure that eliminates relative movement between the seal and the transition piece to thereby eliminate wear.

1. An integral aft seal for sealing an interface between a transition piece component and a first stage nozzle component of a gas turbine, said aft seal comprising:a monolithic and consubstantial seal material having a planar shape including an inner radial portion and an outer portion connected by side portions, and a variable thickness sufficient to span and seal the interface between the outlet of the transition piece and the inlet of the first stage nozzle.
