Abstract

607,205. Making cased valves. EATON MANUFACTURING CO. May 1, 1945, No. 10988. Convention date, March 31, 1944. [Classes 83 (ii) and 83 (iv)] Jointing by forging.-A method of bonding dissimilar metallic members comprises providing a corrosion resisting member with a tapered cavity in one end inserting into the cavity in a non-oxidising atmosphere, the tapered end of the other member of high tensile strength and applying axial pressure to the assembly, which may then be heated and forged to the desired shape. The invention is described as applied to the manufacture of a hollow poppet valve. A member 10 comprising a cylindrical stem 12 and an upper tapered portion 14 is formed from a metal having high tensile strength at elevated temperatures. A cap member 22 having an interior opening slightly smaller than the tapering portion 14 is formed from a corrosion resistant alloy such as 80 per cent nickel and 20 per cent chromium. The two members are assembled under pressure as shown in Fig. 3, in a non-oxidising atmosphere, and the assembly is heated and forged to the form shown in Fig. 5 and finally forged and machined to the final form shown in Fig. 7. Should any defects occur at the line of join of the two materials, an annular portion including the defective part is cut away and a ring 42 of one of the materials is welded or otherwise inserted within the cut.
