The square battery laser welding machine is a device used to weld square battery shells.

 It uses a laser beam as a heat source to weld the outer shell and internal components 

of the battery together. Square battery laser welding machines usually have the following features:

1. High precision: The laser beam has high energy density and high directivity, 

which can achieve high-precision welding.

2. Efficiency: Laser welding is fast and can improve production efficiency.

3. High quality: Laser welding can achieve high-quality welding effects such as no pores,

 no cracks, and no deformation.

4. Automation: Square shell battery laser welding machine can achieve automated 

production and reduce manual intervention.

5. Safety and environmental protection: No harmful gases and noise are generated during laser welding, 

which is harmless to the environment and human health.

Square shell battery laser welding machine is widely used in battery production in the fields of 

new energy vehicles, power tools, energy storage equipment, etc.
