Laser welding can be achieved using either a continuous or pulsed laser beam, and the principle of laser welding can be divided into heat conduction welding and laser deep fusion welding. For heat conduction welding, the power density is less than 104 to 105 W/cm 2, resulting in a shallow melt depth and slow welding speed.
Battery welding with lasers is much faster than with conventional welding tools such as resistance spot-welding or ultrasonic welding. The process is contactless and, unlike resistance spot-welding, requires access to only one side of the part, enabling greater flexibility, lower cost and simpler and faster methods of clamping down parts.
Tab welding is an important step for batteries to function properly. Any misstep will certainly affect how well and how far the battery can last. It can also hamper a battery''s mechanical strength, and thermal efficiency and …
