Abstract

An air bag inflator is manufactured by sandwiching a wire mesh filter between a pair of flat elongated perforate strips of steel, thereafter rolling the sandwiched steel strips and wire mesh concomitantly to form a right circular cylindrical tube with the edge portions of the steel strips orientated in juxtaposed relation to one another, respectively; and welding the juxtaposed edge portions of the strips by a common weld that extends radially across the edge portions of both of the steel strips.
