A MANUFACTURING PROCESS OF WHITE METAL WIRE FOR THE WELDING OF METAL BEARING

摘要

The present invention, transfer heat to be supported, and occurs while reducing the frictional resistance of the guide such as to be moved to a rotated shaft and the horizontal to facilitate the base metal according to the production method of the white metal wires used for welding growth of metal bearing the white metal wire to a method of producing an extrusion which is used to form the metal bearing of the arc welding.; According to the invention, the first step by dissolving the white metal casting a billet, the billet 1.1 ~ 1.2 times than the final diameter of the white metal wire while maintaining the preheating temperature after 2-4 hours pre-heated to a temperature of 120 ~ 140 ℃ the production method of the white metal wires used for the second step, the extruded wire for performing the extrusion welding growth of metal bearing consisting of a third step in the diameter of the end of the fresh white metal wire is provided.
