Battery Pack Laser Welding Machine
As the world transitions rapidly toward electric mobility and high-performance energy storage, the demand for precision battery pack manufacturing continues to accelerate. At the core of this shift is laser welding technology, which delivers unmatched control, repeatability, and speed—critical for producing safe, reliable, and high-efficiency battery assemblies at scale.
Laser welding enables precise joining of challenging battery materials such as copper and aluminium while maintaining low electrical resistance and minimal thermal impact. This is especially vital for bus bars, tabs, and cell interconnections in EV batteries, energy storage systems (ESS), and portable lithium-ion batteries, where weld quality directly affects performance, safety, and lifecycle.

Key Features and Advantages
Copper and Aluminium Welding
The LAVACELL machines excel at laser welding copper and laser welding copper aluminium combinations—historically challenging due to their reflectivity and thermal conductivity. The use of high-peak power fibre lasers with ultrafast pulse shaping ensures:
- Low-porosity welds
- High conductivity joints
- No mechanical stress or electrode damage
Copper Bus Bar Laser Welding
With built-in optical monitoring and adaptive beam shaping, the LAVACELL series enables high-quality copper bus bar laser welding, essential for high-voltage EV battery packs and power distribution systems.
Lithium-Ion Battery Laser Welding
The machine’s precise clamping, real-time weld depth monitoring, and cooling systems make it ideal for lithium-ion battery laser welding, including:
- Tab-to-bus bar connections
- Cell terminal welding
- Interconnect welding in compact modules
Flexible Fixturing
Tooling is customisable for different cell types and module sizes. Pouch, cylindrical (18650, 21700, 4680), and prismatic cells are all supported. This ensures scalability and modularity in your battery production line.
Process Monitoring and Traceability
LAVACELL includes inline quality assurance features such as:
- Vision-assisted weld positioning
- Melt pool monitoring
Process logging and traceability for every weld
