Ear stud energy storage welding

What is energy storage welding?

Energy storage welding is most commonly used for welding studs with smaller diameters. The principle involves the release of stored energy from a capacitor at the moment the stud contacts the base material, causing the area where the stud and the base material meet to melt and weld together.

What is welding studs on a metal base material?

Currently, the process of welding studs onto a metal base material through various welding methods is widely used in electrical cabinets, home appliances, furniture, automotive parts, and various hardware sheet metal parts. These welding methods can generally be divided into two types: energy storage welding and arc welding.

What power sources are used in arc stud welding?

One type uses dc power sources similar to those used for shielded metal arc welding. The other type uses a capacitor storage bank to supply the arc power. The arc stud welding processes using these power sources are commonly known as arc stud welding and capacitor discharge stud welding respectively.

How do stud welding guns work?

Stud welding guns are used to hold the studs and move them in proper sequence during welding. There are two basic power supplies used to create the arc for welding studs. One type uses dc power sources similar to those used for shielded metal arc welding. The other type uses a capacitor storage bank to supply the arc power.

How does the CNC automatic stud welding machine work?

The CNC Automatic Stud Welding Machine is equipped with a milling cutter gun head independently developed by our company, as shown in Figure 16, enabling “de-coating”, splash prevention, and blow-off functions. The “de-coating” function is used when processing galvanized plates.
