Spot welding

Spot welding is a resistance welding process used to join two or more pieces of metal together at discrete points, or "spots." It is widely used in various manufacturing industries, particularly in the automotive sector, for assembling components made from thin sheets of metal. ### Key Features of Spot Welding: 1. **Process**: - The two metal pieces are typically held together under pressure using electrodes. - An electric current is passed through the electrodes and the materials to generate heat due to electrical resistance.
