Abstract
The cost and ease of manufacture and assembly of airbag inflators is enhanced by welding sections of the inflator housing together in a recessed portion of the side wall of such housing. By providing a portion of the housing side wall which is recessed sufficiently that it contains all of the weld flashing produced during the welding operation it is possible to eliminate the machining operation for removing such flashing which, otherwise, could be required to provide external dimensions within specification.
