Abstract

See full text

A perimeter weld flange comprising an inner and external perimeter wall surface and a perimeter weld lip on said flange for welding said flange onto a receiving surface. The perimeter weld flange herein is particularly suitable for weldable metal-gasketed ultra-high vacuum joints, and is also conveniently welded onto tubes, cones, ellipsoids, plates and other shapes, including even irregular shapes, in addition to spheres.
