Hermetically sealed apparatus with seal guard

摘要

Certain exemplary aspects of the present disclosure are directed towards an apparatus in which a base deck and a cover are coupled to one another via a coupling that forms a hermetic seal around a cavity defined by the base deck and the cover. A guard protects the coupling from external forces via a surface aligned with and extending along the coupling.

主权项

1. A disc drive apparatus comprising:
a base deck including a cavity within the base deck; a cover that encloses the cavity and includes a periphery extending along a lip of the base deck; a weld that joins the lip of the base deck to the periphery of the cover, the weld including a portion of material from the lip blended with a portion of material from the periphery of the cover, the weld being configured and arranged with the cover and the base deck to hermetically seal the cavity; and a guard having a surface aligned with and extending along the weld and coupled to at least one of the cover and the base deck, the guard being configured and arranged to protect the weld from external forces.
