Spot welding is a resistance welding process used to join two or more metal sheets together by applying pressure and heat from an electric current to a small “spot” area. The heat generated by electrical resistance melts the metal, forming a strong, localized weld upon cooling. Commonly used in the automotive, manufacturing, and sheet metal industries, spot welding is ideal for joining thin steel or stainless-steel sheets. It offers high welding speed, consistent quality, and minimal material distortion. This process is cost-effective, easy to automate, and widely used in mass production for assembling components like car bodies, appliances, and metal furniture.
