Welding heat input is relatively low (30% less than composite welding), reducing equipment wear and energy loss;

The swing welding method has high adaptability to the assembly quality of workpieces and reduces defects caused by problems such as assembly steps;

The swing welding method has a strong repair effect on weld pores, and this method has an extremely high yield rate in repairing weld pores of battery cells;

Laser welding features precise control, small focused light spots and high-precision positioning. It can be easily automated with robotic arms to improve welding efficiency.
