1.Description
Resistance welding machine is a method to press the workpiece to be welded between two electrodes, apply current, and heat it to molten or plastic state by using the resistance heat effect generated by the current flowing through the workpiece contact surface and adjacent areas, so as to form metal bonding.
2.Type:
Resistance welding machines are classified according to welding methods, including spot welding machines, seam welding machines, projection welding machines and butt welding machines. According to the pressure forms of electrodes, resistance welding machines are classified into lever type, electric cam type, pneumatic type, hydraulic type, and pneumatic hydraulic combined type; According to the type of welding current of resistance welding machine, there are single-phase power frequency welding machine, secondary rectifier welding machine, three-phase low-frequency welding machine, capacitor energy storage welding machine and inverter welding machine
