ABSTRACT:
A steam turbine nozzle singlet having a blade or airfoil between inner and outer sidewalls is provided. The sidewalls include steps or flanges which are received in complementary recesses in the rings enabling axially short low heat input welds e.g., e-beam welds. These complementary steps and recesses mechanically interlock the singlet between the rings preventing displacement of the singlet in the event of weld failure. The low heat input welds minimize or eliminate distortion of the nozzle flow path. Additional features on the singlets, provide a datum for milling machines to form singlets of different sizes.
