Blades in the steam path of a steam turbine diaphragm are assembled into slots in full circular bands and are structurally bonded thereto by welding. After stress relief, the bands are each separated into two 180 degree pieces by line cuts which pass between adjacent blades. The bands are then welded to semicircular rings having planar mating surfaces. The welding of the rings to the bands is performed with minimum welding without concern for whether the welds enter the interface sufficiently far to contact the blades themselves.
