Spot welding is a resistance welding method used to join two or more overlapping metal sheets, studs, projections, electrical wiring hangers, some heat exchanger fins, and some tubing. Usually power sources and welding equipment are sized to the specific thickness and material being welded together.
In general, resistance welding methods are efficient and cause little pollution, but their applications are somewhat limited and the equipment cost can be high. [43] Spot welder. Spot welding is a popular resistance welding method used to join overlapping metal sheets of up to 3 mm thick. [43]
