Can laser welding be used in EV battery production?

Of these, laser and ultrasonic welding processes dominate in EV battery manufacture – with laser welding the preferred solution for mass production – and continue to be improved and refined. “We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech.

Why is welding important for EV battery systems?

Welding is a vitally important family of joining techniques for EV battery systems. A large battery might need thousands of individual connections, joining the positive and negative terminals of cells together in combinations of parallel and series blocks to form modules and packs of the required voltage and capacity.

What are the different types of battery welding?

Battery tab welding. Battery can welding. Battery pack assembly. For each battery spot welding application and type of battery manufactured, AMADA WELD TECH offers a production solution: resistance welding, laser welding, laser marking, laser surface cleaning or laser cutting.

What types of welding do EV batteries need?

“In these situations, cooperative development and reliable relationships are of high value.” While there many kinds of welding, in EV battery applications the most common are resistance welding and laser welding, along with ultrasonic welding and wire bonding, and benefit from standardisation for mass production.

Can a battery be welded?

There are only so many ways to join materials together, and for battery applications – particularly where high currents and voltages and tough operating environments are encountered – welding beats alternatives such as soldering, conductive adhesives and mechanical fasteners.

Can UW Weld a battery current collector?

Compared with alternative methods such as laser welding and brazing, using UW to produce composite thickness busbars for battery current collectors produces wider and stronger welds of greater cross-sectional area, the company says. Mark Boyle notes that UW handles dissimilar metals well, but the vibration can damage nearby components.
