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.

[ What is claimed is:] [1.] A method of manufacturing an airbag inflator assembly comprising a container constructed and arranged to contain pressurized gas and having an opening defined by a peripheral surface surrounding the opening, a burst disc member constructed and arranged to form a seal with said peripheral surface to seal said opening, and an ignitor assembly constructed and arranged to generate sufficient force to break the seal formed by the burst disc member, said method comprising:placing the container, the burst disc member, and a 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 of the airbag inflator assembly;applying force i) to urge a surface portion on one side of the burst disc member and the peripheral surface surrounding the opening in said 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 said ignitor assembly housing into forcible engagement with one another;applying pulses of electrical discharge 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 so that the desired pressure is contained within the container, 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.
