Abstract: A process for sealing the exposed aluminum core of a workpiece formed of stainless steel clad aluminum material of the type in which sheets of stainless steel are bonded to the opposite side of an aluminum core to form a stainless steel skin on each side thereof. In the first step of the process, one side of the stainless steel skin (24) and substantially all of the aluminum core (14) are skived off below the exposed edge (22) of the workpiece along a cut (26). The cut (26) in the aluminum core is then ground into the shape of a convex meniscus (30). In the third step, the skin (24) on the skived off side, which extends above the meniscus (30), is rolled inwardly over the meniscus (30) and in the fourth step, the unskived skin (28) is rolled inwardly over the meniscus, thereby completely sealing the aluminum core.

Abstract: An apparatus and method for connecting bimetallic members by explosive bong. The apparatus comprises a bimetallic collar having an outer aluminum ring and an inner steel ring that are connected by explosive bonding. The steel fitting is welded to the steel ring and the aluminum ring is welded to the aluminum deck. The method of making the bimetallic collar is by vertically and concentrically mounting an inner solid steel cylinder, an intermediate hollow aluminum cylinder, and an outer cardboard cylinder and thereby forming an annular acceleration cavity between the steel and aluminum cylinders and an annular powder cavity between the aluminum and cardboard cylinders. The annular powder cavity is filled with powder and ignited. The explosion causes the aluminum of the aluminum cylinder to accelerate across the acceleration cavity and become bonded to the outer surface of the solid steel cylinder. The solid steel cylinder is then bored out leaving an aluminum cylinder explosively bonded to a hollow steel cylinder. The bonded cylinders are then sliced leaving a plurality of explosively bonded concentric aluminum and steel rings. This technique has been particularly useful for connecting steel fittings to the aluminum decks of ships.

Abstract: A method of fabricating a gate valve having a hollow body with inlet and outlet conduits mounted therein and seat support members mounted on inner ends of the conduits includes fabricating and stress relieving a seat support assembly, then machining it to finished dimensions, then inserting the seat support assembly into a hollow body member. After this is done, the seat support assembly is welded inside the hollow body member. Local stress relieving of welds in the body can be employed during and after assembly and welding.One arrangement includes inlet and outlet conduit sections welded to the hollow body and opposed inner conduit sections having the opposed seat support members thereon with the inner conduit sections welded to the inlet and outlet conduit sections from a position inside the conduits to form a continuation of the outer conduit sections. Another arrangement includes inlet and outlet conduits having seat support members welded and finish machined prior to assembly. These conduits are positioned inside the hollow body with the seat support members in a spaced relation and welded inside the hollow body. Annular grooves in the seat support members adjacent the seat pockets aid in stress relieving. A gate is movably mounted between the seat support members.

Abstract: The invention relates to a process for the manufacture of a generally flat triangularly shaped metal deflector for installation to the interior non-tangential surface of an inlet pipe to the bowl of a centrifugal separating cyclone. The deflector constricts the inlet cross section to the bowl by about 19% to about 32%. The process comprises the steps of selecting a pipe section of the same size as the inlet pipe and marking the chord ends at the center angle between 118.degree. and 149.degree., preferably close to 120.degree.; marking the chord on a template sheet to fix the width of the base of the deflector pattern; determining the length of the deflector at its triangular apex and so marking the template sheet; cutting the sheet at the base and cutting the triangular sides slightly beyond the edges for later trimming near the apex; trimming the top apex of the sheet to form a short straight line parallel to the base and trimming the sides to form arcuate sides, thereby completing the deflector pattern; cutting a metal sheet to the form of the deflector pattern; and welding the cut deflector at its side edges and apex within the pipe at an angle of 8.degree. to 12.degree..

Abstract: A nuclear-fuel assembly has an end plug and is sealed except for a small diameter axial bore in the plug. A welding electrode of the same material as the plug has an end ground to a point. The tapered end is then inserted into the bore. Before the bore is sealed the assembly is filled with an inert-gas at high pressure. An electric welding current is then directed through the electrode and the plug to seal the bore.

Abstract: A solid state bonding process of malleable metals employing the isothermal solidification of a liquid interface to overcome bonding problems inherent in certain material combinations especially when subjected to high annealing temperatures. The technique employs the use of a solid metal interliner clad between the two components to be bonded which has a lower melting point than the adjacent components, is diffusible into either one or both of the adjacent components and maintains ductility after alloying with the adjacent components. The composite material is then heat treated above the melting point of the interliner causing momentary liquifying of the interliner, diffusing the liquid metal into either one or both of the adjacent components thereby forming a progressively higher melting point alloy and subsequent isothermal solidification of the high melting alloy to securely bond the two components together.
