How Does a Spot Welding Gun Work?

A spot welding gun works by passing an electrical current through two or more overlapping metal sheets while applying controlled pressure to the welding area. The electrical resistance between the metal surfaces generates heat, allowing the materials to reach the temperature required for joining. The welding electrodes then maintain pressure to create a strong and consistent welded joint.

This process is particularly useful for joining thin metal sheets without requiring additional filler materials. The controlled application of heat and pressure makes spot welding suitable for repetitive manufacturing tasks where speed, accuracy, and consistency are important.

Modern spot welding systems can incorporate advanced control units, adjustable welding parameters, and efficient electrode designs. These features help operators achieve reliable results across different materials and production requirements.
