AC Butt Welding Machines

AC butt welding machines use alternating current as the power source to join two metal workpieces end to end through resistance heating and upsetting force. The equipment delivers stable heat input and reliable forging pressure, resulting in strong and consistent joints without the need for filler materials. AC butt welding machines are suitable for welding bars, wires, pipes, profiles, and similar components made of carbon steel, low-alloy steel, and non-ferrous metals. They are widely applied in metal product manufacturing, construction materials, wire and cable processing, automotive parts, and machinery fabrication. The machines are characterized by simple structure, convenient operation, low operating costs, and high production efficiency, making them a practical solution for mass butt-joint production.
