Abstract

A mold welded with a dissimilar metal member manufactured by pressingly bringing the dissimilar metal member into contact with a mold formed of copper or a copper alloy in a stationary state while rotating the dissimilar metal member at a high speed, stopping the dissimilar metal member, and providing a forced pressure larger than the pressure in the first step to the mold. The present mold solves the problems of efficient cooling and attachment of back frame. Also, a variety of problems including cutting processing loss of copper or copper alloy plate, long processing times, heat distortion and heat deterioration of copper plates, etc, can be solved. Further, welding position precision and welding strength of stud bolts can be improved. Finally, the invention concerns a mold welded with a dissimilar metal member where the mold is manufactured by the first step shown above.
