ABSTRACT:
A method of affixing an aluminum rupture disc assembly to a 356 aluminum alloy heat-treated aluminum casting is disclosed wherein the rupture disc is of 1100 aluminum alloy, the disc is welded to a tubular member of 2219 aluminum alloy which in turn is fillet welded to the 356 aluminum alloy casting using a 4145 aluminum alloy rod. The disc is welded to the support member by an electro beam or TIG process while fillet welding of the support member to the 356 aluminum alloy casting is preferably accomplished by a TIG method. The procedure allows a rupture disc assembly to be mounted on a 356 aluminum alloy electronic housing unit which contains components cooled by a gaseous medium without adversely affecting the physical characteristics of the rupture disc, the support member therefor, or the cast housing.
