4. Welding current and time: Welding current and time are important parameters that affect welding quality. If the welding current is too high or the time is too long, it may cause the welding point to overheat or the battery to be damaged.
5. Battery surface: After welding, the battery surface should be checked for obvious deformation, burning, or oxidation, as well as whether the welding cap is firm.
6. Battery parameters: Check whether the welded battery parameters meet the requirements, such as voltage, internal resistance, etc.
7. Welding environment: The cleanliness, temperature, and humidity of the welding environment can also affect the welding quality, and it should be ensured that the welding environment meets the requirements.
The above are some methods and indicators for judging the welding quality of lithium battery spot welding machines, which need to be comprehensively evaluated based on actual situations. If the welding quality is found to be unqualified, the welding parameters or equipment should be adjusted in a timely manner, or re welding should be carried out. Meanwhile, quality traceability and improvement can also be achieved through testing equipment and welding quality records.
