The rapid decline and slow rebound of resistance welding machines may be caused by some factors during the welding process, some of which may include:
1. Poor electrode contact: If the contact between the welding electrode and the workpiece is poor, the current may encounter greater resistance during the welding process, resulting in a faster descent stage and slower rebound stage.
2. Surface contamination of electrodes: If there is dirt, oxides, or other harmful substances on the surface of the electrode, it can cause uneven distribution of current during welding, resulting in a fast decrease rate and a slow recovery rate.
3. Inappropriate welding parameters: Incorrect welding parameter settings, such as current size, welding time, etc., may result in uneven temperature distribution during the welding process, thereby affecting the speed of descent and rebound.
4. Unstable electrode pressure: If the pressure of the welding electrode is unstable or insufficient to ensure good contact, it may cause resistance changes during the welding process, affecting the welding speed.
5. Electrode wear: If the welding electrode is severely worn, it may cause uneven current distribution during the welding process, affecting the welding speed and quality.
To solve this problem, the following measures can be taken:
Ensure that the welding electrodes and workpiece surfaces are clean, avoiding the presence of dirt and oxides.
Adjust welding parameters to ensure they are suitable for specific welding tasks and materials.
Check the condition of the welding electrodes and replace severely worn electrodes in a timely manner.
Ensure good contact between the welding electrode and the workpiece, and adjust the electrode pressure in a timely manner.
Regularly inspect and maintain welding equipment to ensure its normal operation and stability.
Through these measures, the phenomenon of rapid decline and slow recovery of resistance welding machines can be improved, and the welding quality and efficiency can be enhanced.
