Turbine vane segments having outer and inner bands and a vane extending therebetween are welded one to the other by E-beam welding along their adjoining margins and from the outside of the bands. The adjoining margins on the hot gas path sides of the outer and inner bands are chamfered, TIG-welded and machined to provide a smooth, continuous gas path surface. The aft hook of each segment is cut back to provide inset faces in a radially projecting flange and a flange extending axially from the radial flange. A filler piece having a body shaped to correspond to the shape of the space between the inset faces of the radial flange is E-beam welded to the radial flange. Gaps between a tongue on the filler piece and the inset faces of the axially extending flange are provided with weld filler material and TIG-welded to complete the welding of the aft hook.
A method of welding first and second stator vane segments to one another wherein each segment includes an outer band, an inner band and a vane extending between the bands comprising the steps of:
