The principle of the energy storage welding machine is to charge a group of high-capacity capacitors through a small transformer in advance to store energy, and then discharge the welded parts through a high-power resistance welding transformer. The outstanding characteristics of energy storage welding machine are short discharge time and large instantaneous current, so the thermal influence such as deformation and discoloration after welding is extremely small. Low-power energy storage welding machines are suitable for welding delicate parts, and high-power energy storage welding machines are suitable for multi-point projection welding, ring projection welding, and seal projection welding.
The main features are as follows:
1. Low requirements on the power grid without affecting the power grid
Because the principle of the energy storage welding machine is to first charge the capacitor through a low-power transformer and then discharge the workpiece through a high-power welding transformer, it is not easily affected by the fluctuation of the power grid. The impact is much smaller than the AC spot welder and secondary rectifier spot welder with the same welding capacity.
2. Short discharge time and small thermal influence
Because the moment of discharge is less than 20ms, the resistance heat generated by the part is also conducted and diffused. The welding process has ended and cooling has begun, so the deformation and discoloration of the welded part can be minimized.
3. Stable welding energy
Because each time the charging voltage reaches the set value, the charging is stopped and switched to discharge welding, so the welding energy shake is extremely small, ensuring stable welding quality.
4. Extremely large current, suitable for multi-point, ring-convex welding, pressure-resistant sealed projection welding process.
5. No water cooling is required, saving energy consumption.
Because the discharge time is extremely short, it will not cause overheating when used for a long time, and the discharge transformer and some secondary circuits of the energy storage welding machine simply do not need water cooling.
The energy storage welder is also the highest and most reliable welding method for making high-strength steel, hot-formed steel spot welding and nut bump welding of cars, and it is not necessary to return teeth when the nut is welded.
