SPOT WELDING TECHNICAL INFORMATION
Resistance Spot Welding is the joining of overlapping pieces of metal by applying pressure and electrical current. These joints created by resistance spot welding form a “button” or “fused nugget.” Resistance spot welds are found typically on flanges, staggered in a single row of consecutive welds. Vehicle manufacturers use resistance spot welding in the factory because they can produce high quality welds at a very low cost.
