What are the characteristics and advantages of capacitor energy storage spot welder? [CD0１]
Dec 19,2023
The capacitor energy storage welding machine is used to charge the capacitor after the alternating current is rectified by the rectifier, and the stored electric energy is converted into low-voltage, energy-concentrated and stable pulse current by the welding transformer. The resistance heat is generated through the contact point of the welding work piece, and the metal piece is fused instantaneously.
Capacitor energy storage spot welding machine has the following main characteristics and advantages:
- Low voltage input, high current output.
The instantaneous current of the energy storage spot welder is very large. The capacitor releases the electric energy to the welding part, which makes it heat and melt instantly. High current instantaneous discharge can achieve higher welding temperature and thermal energy density, also effectively eliminate the oxide and oil on the surface of the workpiece. Thus the quality of welding and molding degree gets improved.
- Short welding time, small heating effect is small, small welding deformation and slight impact to the power grid.
Energy storage welding machine discharge time is extremely short, usually in about 10 milliseconds. Before the welding part of the heat has spread, welding action has been completed. The welding spot begin to cool immediately. Therefore, energy storage welding achieves small heating effect area, small welding deformation, small color change on workpiece surface, small welding trace. It is suitable for welding workpieces of high surface requirements on good looking .
- Achieve low energy consumption and repeated precise projection welding effect
The working mode of large current and short pulse makes stable current output. The instantaneous power taken from the power grid is low. The power factor is high. These lead to concentrated heat provided to the welding area. The result is small welding deformation of the workpiece. It can be used for those difficult welding of non-ferrous metals with good thermal and electrical conductivity. It can achieve low energy consumption and repeated precise projection welding effect, ensuring high production output and good welding effect.
- The welding energy is stable.
The charging voltage reaches the set value each time before the charging will stop and switch to discharge welding. So the welding energy fluctuation is small and the welding quality is stable.
- Time can be controlled.
Automatic welding method is adopted on energy storage spot welder. The corresponding pre-pressure time, pressure time, holding time, welding current and other parameters can be set according to different welding materials. Accurate and adjustable control enables this machine to be especially suitable for large current projection welding. It does good job of single spot welding, multi-point continuous welding and ring projection welding.
- No need of water cooling, energy saving.
The discharge transformer and some parts of secondary circuit of the energy storage spot welder hardly need to be cooled by water because of the short discharge time and no overheating during long-term use.
- Good at welding of metal point and surface
Because the welding time is extremely short, the actual welding time can not be controlled nor adjusted. It is not suitable for welding thick metal workpieces. The welding of metal point and surface is preferable.
Capacitor discharge energy storage welding is capable for a wide range of metal parts, in addition to welding Ferrous steel, iron, stainless steel, mainly used for welding Non-ferrous metal, such as copper, aluminum, silver, nickel and other alloy materials. It can weld structures with different physical properties or different thickness, especially in welding dissimilar metals and light alloys. It is unique in multi-layer spot welding such as foil, wire and thread.
Because of its advantages over other welders, energy storage spot welders have been widely used in automotive parts, electronics, home appliances, construction, hardware, furniture, metal utensils, lamps and lanterns, toys and other industrial manufacturing.
In particular, energy storage spot welder is the most reliable welding method for spot welding of high strength steel, thermal forming steel and projection welding of nuts.
