Processing method of automotive parts by direct resistance heating

摘要

The present invention relates to manufacture auto parts way by direct conduction heating, by weight of the center pillar and the reduced part count and character center heat treatment of energization heating method at the time of the filler preparation, so as to obtain the strength reinforcement or more, also achieved with a lighter to remove the reinforcement to the existing one so that it can obtain a high-strength parts of the center pillar.; To this end, the invention hayeoseo forming a high-strength steel sheet with a press, and heat-treated in a direct conduction heating method in which the stiffener is welded in the formed steel plate position, light (硬) a martensitic structure and open (軟) a base in the heat treatment section provides a direct method of producing automotive parts to the energization heating, it characterized in that the tissue to be mixed.
