Why Does The Current of The Energy Storage Welding Machine Decay?

The current attenuation of energy storage welding machines may be affected by various factors. The following are some common reasons that may cause current attenuation in energy storage welding machines:

1. Poor electrode contact: If there is poor contact or gap between the welding electrode and the workpiece, current transmission may be obstructed, resulting in current attenuation.

2. Welding electrode wear: With the use of welding electrodes, the electrode surface may wear down, resulting in a decrease in welding surface area, which affects the efficiency of current transmission and leads to current attenuation.

3. Elevated welding electrode temperature: High power welding processes may cause an increase in welding electrode temperature. An increase in temperature will increase the resistance of the electrode, thereby affecting the transmission of current.

4. Elevated welding point temperature: High power welding processes can cause an increase in temperature around the welding point. If the welding point is in a high temperature state, it may increase the contact resistance between the welding electrode and the welding point, resulting in current attenuation.

5. Decreased discharge rate of capacitors: Energy storage welding machines use capacitors for power supply, and the decrease in discharge rate of capacitors may lead to an increase in internal resistance of capacitors, thereby affecting the efficiency of current transmission.

6. Welding circuit failure: Connection failure, component damage, or circuit disconnection in the circuit may cause current transmission to be obstructed, resulting in current attenuation.

7. Welding environmental factors: Environmental factors during the welding process, such as humidity, temperature, and the surface condition of the workpiece, may also affect the efficiency of current transmission, leading to current attenuation.

To avoid or alleviate the problem of current attenuation in energy storage welding machines, the following measures can be taken:

• Regularly inspect and maintain welding equipment to ensure good contact between electrodes and workpieces;

  
  

• Equipped with high-quality and wear-resistant welding electrodes, and promptly replace severely worn electrodes;

  
  

• Control welding parameters to avoid high electrode and welding point temperatures caused by high-power welding;

  
  

• Keep the capacitor in good condition and regularly replace it to ensure sufficient discharge rate;

  
  

• Pay attention to welding environmental factors and ensure that the welding process is carried out under suitable environmental conditions.
