Abstract
Halves of a torus, bridge ring and nozzle are fitted up on tapered fits and clamped one to the other. Weld preps are performed on the torus and nozzle surfaces to be welded. Weld material is applied along the inner and outer radii, initially in a root pass to consume the metal, in subsequent intermediate passes to build up the base metal and finally in a rapid deposition of weld material, e.g., using submerged arc process. The nozzle box assembly half is then stress-relieved, X-rayed and machine-finished.
