Embodiments of this invention include a nozzle assembly (10, 100) for a turbine, the nozzle assembly (10, 100) including an airfoil (12, 102), inner and outer sidewall's (16, 106) and inner and outer ring's (20, 110). Each of these sidewalls and rings are coupled together at an interface (80) through a combination of a mechanical interconnection on one end and a welded connection on the other end. The mechanical interconnection includes either the sidewalls or the rings having a protruding hook (130) and the other having a corresponding hook recess (132). The interconnection can also include axial and radial mechanical stops. The configuration may further include one or more surfaces at an interface (80) between a ring and a sidewall 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). |
