Lithium ion battery spot welding machines may encounter various malfunctions during use. The following are some common fault situations:
1. Unstable solder joints: may be caused by incorrect welding current or time settings. If the current is too small or the time is too short, the welding point may not be firm enough.
2. The appearance of bubbles or holes at the welding point may be caused by surface contamination during welding (such as oxides, grease, etc.). Before welding, ensure that the welding surface is clean.
3. Excessive electrode wear: If the electrodes are frequently replaced or worn too quickly, it may be due to improper selection of electrode materials, excessive electrode pressure, or improper welding parameter settings.
4. Welding deformation or melting: If there is deformation or melting of the welding material during the welding process, it may be due to reasons such as high welding temperature or long welding time.
5. Unstable welding current: may be caused by unstable welding power supply voltage, poor electrode connection, or electrode damage.
6. Welding electrode damage: The electrode may be damaged during long-term and high-frequency use, such as deformation, fracture, or burning.
7. Welding machine malfunction: The welding machine itself may have malfunctions, such as control system failure, power supply failure, wiring connection problems, etc.
8. Other faults such as damaged welding fixtures, uneven welding heads, and unstable workpiece positions may also affect welding quality.
For these common faults, the following measures can be taken for troubleshooting and handling:
① Regularly check the condition of welding equipment and electrodes to ensure their normal operation.
② Adjust welding parameters such as current, time, pressure, etc. to improve welding quality.
③ Clean and treat the welding surface to ensure that it is free of contamination.
If there is a serious malfunction, please contact the manufacturer or professional technical personnel for repair and handling in a timely manner
