Abstract
The turbine nozzle diaphragm includes nozzle diaphragm segments formed of a subassembly including inner and outer spacer bands with airfoil-shaped partitions circumferentially spaced one from the other secured to the inner and outer spacer bands. Inner web and outer ring segments are secured to the inner and outer spacer band segments, respectively, to form nozzle diaphragm segment halves. End surfaces of the inner webs and outer rings lie in a plane passing through the axis of the nozzle diaphragm. The spacer bands have flanges projecting from the ends of the segments with weld material built up behind the flanges to provide additional support for the trailing edge portions of the partition adjacent the joint. Complementary recesses are formed in the opposed ends of the opposite segment whereby a Z-joint requiring limited material and labor is formed.
