Battery Laser Welding For Battery Pack Manufacturing

Meet High-Speed
Production Requirements

With more than 6kW of laser power, the welding speed can be scaled to meet short cycle time requirements.

Lasers also require minimal maintenance, so they are ideal for production line automation.

Minimize the
Heat Affected Zone

Laser welding can be optimized for minimal heat input. As a result, batteries do not suffer from excessive heating and maintain better mechanical properties.

Join
Dissimilar Metals

Lasers can weld dissimilar materials with varying fusion temperatures without the need for filler material. Examples include steel-copper, steel-aluminum, aluminum-copper, and steel-nickel.

Adapt Quickly to
Production Variations

Laser parameters can be updated automatically for different needs. This is ideal if you are working with multiple module and pack designs involving various cell types and busbar thicknesses.

The welding process can also be updated on the fly for different thicknesses.

Customize
Welding Patterns

Because laser welding is a non-contact technology performed remotely, welding patterns can be customized and optimized for each application. This guarantees strong and reliable bonds regardless of the welding area’s size, shape, or location.

Improve
Electrical Conductivity

Metals joined by laser welding have an excellent electrical conductivity and better heat management at the welded joints (due to minimal resistance).
