The 2000W fiber laser welding machine equipped with an XY axis system has significant technical advantages and applicability in the field of battery welding (such as power batteries and consumer electronic batteries). Combining high-power lasers with automated motion control, it can meet the stringent requirements of battery manufacturing for high precision, high efficiency and consistency. The following are its core advantages and features:
### **1. High precision and micron-level welding capability**
- **Precision spot control**: The 2000W fiber laser has high beam quality (M² close to 1), and the focused spot can reach the micron level, which is suitable for precise welding of tiny welding points such as battery tabs and battery core connectors. The weld width is small (0.1-0.5mm), and the heat-affected zone is small to avoid damage to sensitive battery materials.
- **XY axis positioning accuracy**: The XY axis system is driven by a servo motor, and the repeated positioning accuracy reaches ±0.01mm, ensuring the precise position of the welding point and avoiding the problem of false welding or short circuit caused by offset, especially suitable for multi-layer battery stacking welding.
### **2. High efficiency and automated production**
- **High-speed welding and deep-melting welding capability**: 2000W high power supports deep-melting welding, which can penetrate high-reflective materials such as aluminum and copper (such as battery aluminum shells and copper poles), with fast welding speed (up to 10m/min or more), and single-point welding time as short as milliseconds, significantly improving production line efficiency.
- **Automation integration**: The XY axis system supports programmed path planning, which can be adapted to robots or automatic feeding devices to achieve continuous welding of battery modules (such as square battery sealing welding and cylindrical battery cap welding), reduce manual intervention, and is suitable for mass production.
### **3. Welding quality and material compatibility**
- **Low heat input and no deformation**: Laser welding is non-contact and has concentrated heat input, which reduces thermal damage to the electrolyte or diaphragm inside the battery, avoids material deformation or microcracks caused by traditional welding (such as resistance welding), and improves battery safety and life.
- **Multi-material adaptability**: Compatible with common battery materials such as aluminum, copper, nickel, and stainless steel, especially suitable for dissimilar metal welding (such as copper-aluminum transition joints), and no solder needs to be added to reduce the risk of pollution.
### **4. Intelligent control and process stability**
- **Real-time monitoring and parameter optimization**: Equipped with an intelligent control system, it can monitor welding current, power, temperature and other parameters in real time, automatically adjust the laser waveform and pulse frequency, adapt to different battery material thicknesses (such as 0.1-3mm), and ensure uniform welds.
- **Data tracing and fault diagnosis**: Supports welding data storage and USB flash drive export for easy quality tracing; built-in fault alarm system (such as overcurrent and overvoltage protection) to reduce downtime.
### **5. Environmental protection and low cost**
- **No consumables and low energy consumption**: The electro-optical conversion efficiency of the fiber laser is ≥30%, and there is no need for consumables such as electrodes and gases. The operating cost is only 1/3-1/2 of traditional welding.
- **Green production**: The welding process is smoke-free and splash-free, meeting the requirements of clean workshops for battery production; the noise is less than 60dB, improving the working environment.
### **Typical application scenarios**
- **Power battery**: battery cell tab welding, module Busbar connection, battery shell sealing welding.
- **Consumer electronics battery**: mobile phone battery cover welding, TWS headset battery precision welding points.
- **Energy storage battery**: copper bar welding of large energy storage modules to ensure high current carrying capacity.
### **Summary**
The 2000W fiber laser welding machine with XY axis system has become an efficient solution in the field of battery manufacturing through **high-precision positioning**, **high-speed deep melting welding**, **intelligent control** and **multi-material compatibility**. Its technical advantages not only improve welding quality and production efficiency, but also reduce overall costs, meeting the core requirements of new energy vehicles, 3C electronics and other industries for high safety and consistency of batteries.
