Abstract

531,986. Making valves. BULLOCK, F. E. Aug. 10, 1939, No. 23066. [Classes 83 (ii) and 83 (iv)] Welded joints. - Poppet valves have the head formed separately from the shank, if desired of different metal, and electrically welded thereto by means of an upset joint. The head is bored and chambered out at b<SP>1</SP> and may in addition have one or more additional chamberings e. The stem reduced in diameter at c over a length depending on the amount of upset required has a pointed end. The parts are assembled between electrodes under axial pressure and. are thus upset and welded.
