Abstract

PURPOSE:To aim at obtaining superior heat resistibility and wear resistibility under high temperature to an engine poppet valve and to reduce the material cost thereof, by forming the bevel part of the engine poppet valve with clad materials. CONSTITUTION:A clad material 10 having a base metal plate 11 at least one side surface of which is formed with a clad metal layer 12, is circularly punched out, and then the punched blank 13 is subjected to a reducing process so that a bevel part 2 having a valve face 3 made up with the clad metal layer 12, is formed. A part of the clad metal layer 12 in the center portion of the bevel part 12 is cut and removed, and then a valve stem member 1 made of materials selected from the same group of the materials of the above-mentioned base metal plate 11 is welded to the removed portion of the bevel part.
