Laser welding boosts power batteries and new energy vehicles
ONE、Dual-wavelength laser hybrid welding for power battery welding
What’s Composite welding
Composite welding combines two different wavelengths of laser light or a laser beam through a special laser exit head to spatially coincide or juxtapose the axes of the two laser beams. The main-band laser is used for deep-fusion welding, and the sub-band laser has the functions of preheating and post-weld slow cooling, and moderate heat conduction welding.
Composite Welding Advantage
Improve welding efficiency
Increase the toughness of the weld
Reduce cooling rate
Improve joint structure performance
Improve surface molding and reduce defects such as splashes, shrinkage holes and undercuts

Welding effect of power battery negative parts
Welding effect of power battery components
Power lithium battery is the "heart" of new energy vehicles, and its quality directly determines the performance of the entire vehicle. The welding method and welding process will directly affect the cost, quality, safety and battery consistency of lithium batteries. Laser welding stands out from many welding methods and has been widely used in lithium battery manufacturing and new energy vehicle manufacturing to replace traditional welding technologies.
As one of the main forces of domestic fiber lasers, Maxphotonics will spare no effort to provide high-quality, high-reliability light sources and solutions for power lithium batteries and intelligent manufacturing equipment for new energy vehicles!
