What is a Resistance welding machine?

A resistance welding machine is a device used to join metals by utilizing electrical resistance. The process involves clamping the metal parts with electrodes and passing a high electric current for a short duration. The heat generated by the electrical resistance at the contact points melts the metal, forming a strong bond. Resistance welding methods include spot welding, projection welding, and seam welding. It is widely used in industries like automotive manufacturing and home appliance production due to its fast welding speed and minimal heat impact on the workpiece, making it ideal for thin metal sheets and small parts.
