Capacitance discharge stud welder

Features

Time-saving and cost-effective

Convenient to use: no need other steps in other welding methods like drilling, punching, threading, riveting, threading, and finishing.

Continuously expanding the application potential of structural design

With short time, big current and low penetration depth in the welding process, the stud can be welded onto very thin plates. For plates using ceramic ring arc stud welding and short cycle arc stud welding, the thickness can reach as thin as 1mm. For capacitance discharge arc stud welding, the thickness can reach as thin as 0.6mm, while for energy storage stud welding, the thickness can reach as thin as 0.5mm.

The workpiece for stud welding must be welded from one side.

It can be welded in all positions and can be welded to restricted vertical partitions with the help of an expander.

Due to the short welding time and minimal deformation after welding, no repair is required.

Because the welded structure does not require drilling, it will not cause leakage.

The joint welded with bolts can achieve high strength, that is, the strength of the joint welded with bolts is greater than the strength of the bolts themselves.

After welding the coating or high alloy sheet, there are no imprints on the back.

Good economic viability

The advantage of stud welding over other welding methods lies in the welding power. For mass-produced workpieces, 8-40 pieces/min can be produced in a very short welding time (3-980ms) (depending on different diameter bolts and welding power). The automatic feeding screw welding machine can achieve ultra-high efficiency of 60 pieces/min.

Standard bolts are low-cost.

There are various types of stud welding equipment and welding guns, and the purchase cost of the equipment is relatively low.

According to the product, it can be made into a multi station automatic welding machine or a high-precision gantry CNC automatic welding machine.

Stud welding has a high quality reproduction rate and a low scrap rate.

Attention should be paid to the application of stud welding:

Like other fusion welding, stud welding also has certain limitations on the carbon content in steel - for structural steel studs, the carbon content should be within 0.18%, while the carbon content of the base material should be within 0.2%.

According to the different methods of stud welding, the recommended combination of stud material and base metal should be used for welding, otherwise there will be non melting between the stud and base metal. The combination of stud materials and base materials beyond the recommended range should be tested to determine weldability and product design requirements for relevant inspection and evaluation possibilities.
