A nozzle assembly (100) for a turbine including an airfoil (102), inner and outer sidewall's (104, 106), and inner and outer ring (108, 110)s is provided. The sidewalls (104, 106) and rings (108, 110) are coupled together using a weld and mechanical interconnection, including axial and radial mechanical stops (107, 109) to allow for an accurate assembly, to ensure correct radial and axial positions of the parts during welding, to minimize weld shrinkage and to control an axial weld length. The configuration may further include one or more surfaces at an interface (80) between a ring (108, 110) and a sidewall (104, 106) angled away from the interface (80) to form a narrow groove (120). The configuration further may include a ring with a consumable root portion (122) to facilitate the weld, and to provide a fixturing stop to further ensure that the parts remain in the correct position. |
