The butt workpiece is automatically clamped and then controlled by the gas-liquid system, first applying voltage and pressing slowly to eliminate workpiece surface oxidation and unevenness.

The butt workpiece is automatically clamped and then controlled by the gas-liquid system, first applying voltage and pressing slowly to eliminate workpiece surface oxidation and unevenness. After the fusion is removed, the end surface of the workpiece to be welded becomes thermoplastic, the welding zone becomes hotter and hotter, and the speed of butt welding increases. Through flash and spatter, the two contacting surfaces are completely welded to each other. Finally, the upper forging is quickly pressurized to weld the two ends of the weld, the current is turned off, and the welding is completed. This type of welding has high strength, good density, no false welding, no slag and no pores.

Resistance butt welding is a method of continuously pressing the ends of two workpieces using contact heat to heat the contacting part to a ductile state, and then quickly applying top forging pressure or without adding top forging pressure to maintain only welding pressure to complete the weld.
