1. A method of manufacture for a remote seal, the method comprising:
- welding a fusible metal disc of material having a thickness of between about 1/64 inches and about 3/16 inches to a flange, the metal disc having a hole therein with an inner diameter substantially congruous with an outer diameter of a cavity in the flange, the metal disc and the flange having melting points such that the two may be TIG welded together, whereby disc material may be fused with common TIG welding techniques; and
attaching an outer diameter of a diaphragm made of the same metal as the fusible metal disc to the disc proximate to the inner diameter of the disc such that the diaphragm covers the hole in the disc but exposes a flat portion of the disc.
