Abstract
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.
Claims10
An all-metal vacuum manifold comprising a metal body defining a hollow having an interior vacuum side surface and a spherical exterior surface, said manifold having at least two branch ports extending between the interior surface and the exterior surface, and a hollow flange attached at a perimeter weld lip to said manifold at said each port by a weld formed on the vacuum side of the manifold bridging each perimeter weld lip of said hollow flange and the interior surface of said metal body.
A method for welding a hollow metal flange having a weld lip at one end thereof to a hollow all-metal vacuum manifold body, said hollow metal body having an interior vacuum side surface and a spherical exterior surface, and having at least two branch ports extending between the interior surface and the exterior surface, comprising locating said hollow flange in each said port with a perimeter weld lip adjacent the hollow metal body interior surface, and welding each said perimeter weld lip of said flange to the interior vacuum side surface of said metal body.
