Abstract: This disclosure describes an improved method of electron beam (“EB”) welding utilizing a collection pocket. The method includes providing a first surface and a second surface, forming a collection pocket in at least one of the first surface and the second surface, coupling the first surface to the second surface at a joining location, and EB welding the first surface and the second surface to each other at the joining location. The collection pocket captures and contains excess weld material to prevent the excess material from escaping the joining location, and also reduces an amount of wall thickness required for EB welding. A method of reconditioning gas turbine components is also disclosed.

Abstract: Embodiments for a compressor stator vane assembly in a gas turbine engine are disclosed. In an embodiment of the present invention a stator vane assembly is provided having a plurality of vanes each with an attachment and channels machined into the forward and aft walls of the attachment. A forward hook ring segment is pressfit into the channel in the forward wall of the attachment and an aft hook ring is pressfit into the channel in the aft wall of the attachment. The hook ring segments join a plurality of vanes together so as to provide a uniform engagement of mounting slots in the compressor case. Such an arrangement increases the contact area between the hook rings and the compressor case such that damping of individual vane vibrations are improved and operating stresses are reduced.
