An augment inflator (10) includes a rupture disk (140) covering an annular outlet opening (133) in a housing (40). A piston (150) is welded in the housing (40). Upon actuation of the inflator (10), gas generating material (220) ignites in a combustion chamber (158) in the piston (150). The pressure increases in the combustion chamber (158) until a stress riser (190) on the piston (150) ruptures. A severed portion of the piston (150) moves and a circular cutting edge (182) on the piston shears a circular opening in the rupture disk (140).
