Advantages of laser welding:


1. Laser welding is an integrated production process with positive electrode, negative electrode material, diaphragm, electrolyte and other materials from zero to whole.


2. Conventional battery raw materials, which account for a growing proportion in the cost, are purchased in large quantities by tons; The procurement of raw materials for laser equipment is basically one-time, which saves the cost.


3. Laser welding can greatly improve the safety, reliability and service life of batteries.


1) Laser welding has high energy density, small welding deformation, can effectively improve the accuracy of welding, welding without impurities, uniform and compact, no need for additional polishing;


2) Can accurately control laser welding, light spot concentration, precise position, combined with mechanical hand easy to achieve automatic control, stable equipment work, simple operation, high welding efficiency, short working time, low cost;


3) When laser welding thin sheet or diameter wire, there is no problem of melting back due to arc welding.
