SPOT RESISTANCE WELDING

Spot welding is a resistance welding process used to join two metal sheets together at specific spots, or points, by applying pressure and heat to the area. The process involves clamping the two metal sheets together between two electrode and passing an electrical current through the joint, creating a resistance heating effect that melts the metal at the point of contact. The electrodes are then removed, and the melted metal cools and solidifies, creating a strong and permanent bond between two sheets. Spot welding is commonly used in the automotive industry to join sheet metal panels together, as well as in the manufacture of appliances, electronics, and other metal products. It is a fast and efficient welding process that can produce high-quality welds with minimal distortion, making it ideal for mass production applications. Resistance spot welding machines are available in a range of sizes and configurations, from small handheld units for spot repairs and small-scale operations to large industrial machines capable of welding thick metal sheets with high precision and speed.
