Abstract
An apparatus and process for attaching a liner to a shell of a magnetic disk cartridge. A cover is provided that covers at least a portion of the liner and shell when in an attachment position. The cover has blow-out holes which are positioned around the periphery of the welding head of a welding device. Pressurized air is introduced into the blow holes so as to lift out any dust located in the vicinity of the half shell. An exhaust hole is provided in the cover for removal of the dust by virtue of a suction device.
