Five-in-one laser welding machine leads the innovation of welding technology in the battery industry

26

With the rapid development of the new energy industry, the requirements for welding technology in battery manufacturing are becoming increasingly stringent. Traditional welding technology has been difficult to meet the needs of high precision, high efficiency and low thermal impact, and the five-in-one laser welding machine is becoming the preferred solution for upgrading the welding process in the battery industry with its excellent performance.

 

1. Limitations of traditional welding technology

Traditional welding machines (such as argon arc welding, resistance welding, ultrasonic welding, etc.) face many challenges in battery manufacturing:

1. **Large heat-affected zone**: Traditional welding is prone to high temperature, which causes deformation of key components such as battery poles and sealing rings or degradation of material properties, affecting battery safety and life.

2. **Insufficient precision**: It is difficult to achieve micron-level weld control, and problems such as cold welding and sputtering are prone to occur, and the yield rate is low.

3. **Low efficiency**: Multiple processes need to be completed step by step, the welding speed is slow, and it is difficult to match the large-scale production needs of power batteries.

4. **Poor compatibility**: When welding different materials (such as copper and aluminum dissimilar metals), brittle compounds are easily generated, which is difficult to solve with traditional processes.

 

 

 

2. Technological breakthroughs of the five-in-one laser welding machine

1. **Continuous laser** high-speed welding of shells or seals, with efficiency increased by more than 3 times;

2. **Swing welding** technology widens the weld and reduces pores, improving structural strength.

3. Annular spot technology evenly distributes energy to solve the welding problem of highly reflective materials such as copper and aluminum;

4. A single device can replace multiple traditional welding machines, reducing process conversion time;

5. The welding speed can reach 20m/min, and the yield rate exceeds 99.5%, significantly reducing the rework cost.

3. Recommended application scenarios in the battery industry

The five-in-one laser welding machine has been widely used in:

- **Power battery**: No spatter in the welding of the pole ear to avoid damage to the diaphragm;

- **Energy storage battery**: Large-size shell sealing welding, one-time molding without leakage;

- **3C battery**: High-precision processing of flexible circuits and micro solder joints.

 

In the context of the battery industry moving towards the era, the five-in-one laser welding machine is becoming a key driving force for industrial upgrading with its core advantages of high precision, intelligence and low energy consumption. We call on the industry to actively embrace technological innovation and empower global energy transformation with advanced equipment.
