Product Description


Capacitor Discharge Stud Welding Machine



Product Description


Capacitive energy storage stud welding machine is also called capacitance discharge stud welding machine. It is named because its power supply is a capacitor bank. The capcacitor bank as an energy storage element discharges into the space between the stud and the workpiece instantaneously, forming an instantaneous unstable arc process. The end of the stud and the welding area of the workpiece are melted by the arc heat. The stud is inserted into the molten pool under the pressure of the welding gun spring to form a plant welding joint. This type of welding machine is called a capacitor energy storage stud welding machine.

1. This machine is mainly used for stud connection of various structural parts and decorative parts of low carbon steel, stainless steel and aluminum alloy.Such as various low-carbon steel or stainless steel cabinets, instrument housings, car bodies, kitchenware, hardware products and welding of fixed studs on aluminum alloy ceiling.

2. After welding, there is no deformation or color spot on the back.

3. The welding time is short (1-3ms), and the ratio of stud diameter d to plate thickness s is equal to 8-10. It is especially suitable for stud welding on thin plates. It is characterized by fast welding speed, short welding time and high efficiency. It is the most ideal welding equipment for stud welding.
