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.

[ We claim:] [1.] In an inflator for use in an airbag passive restraint system, comprising:(a) a housing having a side wall extending from a first end to a second end, said side wall including a welded joint between a first section which extends from said joint toward said first end and a second section which extends from said joint toward said second end, each of said first section and said second section defining a substantially equivalent external shape which extends a portion of the distance between said first end and said second end,(b) an igniter mounted at said first end,(c) a gas generating material stored within said housing;the improvement comprising;a recessed portion of said side wall located adjacent said welded joint and recessed a sufficient distance that weld flashing produced during the welding process does not extend to the substantially equivalent external shape defined by said side wall.
