Frequently Asked Questions (FAQs)
1. What equipment is needed for spot welding?
The basic spot welder consists of a power supply, an energy storage unit (e.g., a capacitor bank), a switch, a welding transformer, and the welding electrodes. The energy storage element allows the welder to deliver high instantaneous power levels.
2. What is a spot welding machine?
A spot welding machine is also commonly called a resistance spot welder. Spot welding machine can fuse two or more sheet metals via a heating process performed on the welding point, where the pressure is applied after the metal melts.
3. What products are spot welded?
Spot welding is widely used to manufacture items such as gas sensors, solar panels, switches, high voltage cables, and circuit boards. The method is known to have high electrical resistance, making it ideal for manufacturing complex and delicate electronic items.
4. How thick of metal can you spot weld?
Spot welding is primarily used for joining parts that are normally up to 3 mm in thickness. Thickness of the parts to be welded should be equal or the ratio of thickness should be less than 3:1. The strength of the joint depends on the number and size of the welds. Spot-weld diameters range from 3 mm to 12.5 mm.
