Abstract
Embodiments of this invention include a nozzle assembly for a turbine, the nozzle assembly including an airfoil, inner and outer sidewalls, and inner and outer rings. Each of these sidewalls and rings are coupled together at an interface 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 and the other having a corresponding hook recess. The interconnection can also include axial and radial mechanical stops. The configuration may further include one or more surfaces at an interface between a ring and a sidewall angled away from the interface to form a narrow groove. The configuration further may include a ring with a consumable root portion.
