Abstract
A process for assembling a storage device such as a disk drive storage device using a laser welding technique. A welding fixture holds a storage device component in a predefined three dimensional location with a small gap relative to a second component so that improved dimensional accuracy is achieved. This welding of components that do not touch allows for assembly tolerances that are independent of component tolerances. The welding fixture can use magnetic force.
