Capacitor Discharge Projection Welder Has Low Requirements For The Grid And Does Not Affect The Grid

Capacitor discharge projection welder adopts the principle of double-sided over-flow welding. During the working process, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and when the welding current flows from one electrode to the other, instantaneous thermal fusion is formed between the two contact resistance points, and the welding current flows instantaneously from the other electrode to this electrode along the two workpieces to form a circuit with instantaneous discharge and extremely steep current rise curve. The whole welding process does not exceed 8ms, the deformation is extremely small, the strength is high, the melting depth is generally above 0.2mm, and the internal structure of the welded workpiece is not damaged.

Application: The outstanding feature of capacitor discharge welder is the short discharge time. The instantaneous current is high, so the heat effects after welding such as deformation. The color change is very small. The low power capacitor discharge welder is suitable for welding precision parts, and the high power capacitor discharge  welder is suitable for multi-point projection welding, ring projection welding,seal projection welding.

The features of capacitor discharge projection welder are as follows:

1. Low requirements for the power grid and does not affect the power grid. Since the principle of the capacitor discharge welder is to first charge the capacitor through a low-power transformer and then discharge the workpiece through a high-power resistance welding transformer, it is not easily affected by fluctuations in the power grid. In addition, due to the small charging power, the impact on the power grid is much smaller than that of AC spot welder and secondary rectifier spot welder with the same welding capacity.

2. Short discharge time and low thermal impact. Since the discharge time is less than 20ms, the resistance heat generated by the part is still conducted and diffused, and the welding process has been completed and started to cool down, so the deformation and discoloration of the welded part can be minimized.

3. Stable welding energy. Since the charging voltage stops after each charge reaches the set value and switches to discharge welding, the welding energy fluctuates very little, ensuring stable welding quality.

4. Extra large current, suitable for multi-point,circumferential welding.

5. No need for water cooling, saving energy consumption. Due to the short discharge time, long-term use will not produce overheating, the discharge transformer and some secondary circuits of the capacitor discharge welder almost do not need water cooling.
