Abstract: The present invention relates to methods to join at least first and second metallic components in which a pre-treatment is applied to one or more region(s) of at least one of the components to be welded together before welding takes place. The pre-treatment involves contacting at least a region of the first metallic component with a rotating and translating tool such that the rotating and translating contact locally heats, softens, and mixes successive portions of at least the region of the first metallic component. The first and second metallic components are placed together such that a joint is provided between at least the pre-treated region of the first metallic component and the second metallic component. At least the pre-treated region of the first metallic component is welded to the second metallic component along at least a portion of the joint.

Abstract: A hard drive includes a base deck and process cover that define a cavity for housing data storage components. The hard drive further includes a final cover that is placed over the process cover and is coupled to the base deck. The final cover and process cover are directly coupled to each other.

Abstract: Certain exemplary aspects of the present disclosure are directed towards a disc drive apparatus. A base deck and a cover are joined to one another by a friction-stir weld along a lip of the cover that extends along a periphery of the cover and over a surface of the base deck. The base deck and cover enclose a cavity, which is hermetically sealed by the weld.
