Apparatus with sealed cavity formed by at least one impermeable weld

摘要

Certain exemplary aspects of the present disclosure are directed towards an apparatus in which a base deck and a forged base deck cover are coupled to one another, via a weld joint, to provide a hermetically sealed cavity within. The base deck includes an outer region, and the base deck cover includes a lip that interfaces with the outer region of the base deck to provide the weld joint. Similarly, the base deck is formed by an outer region of a base deck bottom portion interfacing with a lip of the shroud to form, via welding, the base deck.

主权项

1. An apparatus comprising:
a base deck including
a forged base deck bottom portion including a first outer region,an extruded shroud including a lip, the lip configured and arranged for interfacing with the first outer region and for welding of the extruded shroud to the forged base deck bottom; a forged base deck cover including a second outer region, the second outer region configured and arranged for interfacing with the lip of the extruded shroud and for welding to the extruded shroud; and a connecting structure, configured and arranged to provide hermetic sealing of a cavity defined by the base deck and the forged base deck cover, including
a weld material configured and arranged to connect the extruded shroud to the forged base deck bottom and connect the forged base deck cover to the extruded shroud, andat least one shim configured and arranged to realloy the weld material.
