ABSTRACT:
A method of manufacturing an airbag inflator assembly comprising placing a container, burst disc member, and housing for the ignitor assembly in a chamber; pressurizing the chamber to an appropriate pressure based upon a desired pressure to be contained within the container; applying force i) to urge a surface portion on one side of the burst disc member and the peripheral surface surrounding the opening in the container into forcible engagement with one another, and ii) to urge a surface portion on an opposite side of the burst disc member and an associated surface portion of the ignitor assembly housing into forcible engagement with one another; applying pulses of electrical discharge energy i) in the vicinity of the forcible engagement between the surface portion on one side of the burst disc member and the peripheral surface surrounding the opening in the container so that the surface portion on one side of the burst disc member and the peripheral surface surrounding the opening in the container are sealingly welded to one another, and 2) in the vicinity of the forcible engagement between the surface portion on the opposite side of the burst disc member and the associated surface portion of the ignitor assembly housing so that the surface portion on the opposite side of the burst disc member and the associated surface portion of the ignitor assembly housing are welded to one another.
