energy storage cell laser welding
Laser micro welding with fiber lasers for battery and fuel cell
Laser beam welding is a fusion welding process, which depends on the interaction of the work piece with the laser beam and the intensity of the radiation. It can be divided into two categories determined by the outcome: conduction mode welding and deep penetration welding.
