Resistance Spot Welding

Resistance spot welding is a process that joins two metal sheets together by applying pressure and passing electric current through the contact points. The electrical resistance at these spots generates heat, melting the metal surfaces locally. When the current stops, the cooled, fused areas create a strong, permanent bond. This technique is widely used in manufacturing industries like automotive assembly because it is fast, efficient, and produces clean welds without the need for additional filler materials.
