Laser Welding for Lithium-Ion Battery Manufacturing

Weld every cell.
Trust every pack.

FlareLaser builds fiber laser welding systems purpose-built for Lithium-Ion battery production - cell tabs, busbars and module interconnects, welded with the precision and repeatability a battery pack demands.

Flare Fiber Laser Welder
Built & tested in-house for battery welding
Cell Tabs

Copper, nickel & aluminum tab welding

Busbars

Cell-to-busbar & busbar-to-terminal joints

Modules

Pack & module interconnect welding

Automation

Engineered around your line

Built around
the process.

From a focused weld point to a complete automated cell, FlareLaser combines laser technology, motion control, fixturing, sensing and software into production-ready systems.

01 / LASER WELDING

Precision Metal Welding

Controlled heat input, high repeatability and clean weld profiles for demanding metal joining applications.

02 / ROBOTICS

Robotic Welding Cells

Integrated laser heads, robots, fixtures, safety and controls for repeatable production.

03 / BATTERY

Battery Manufacturing

Laser welding solutions for tabs, busbars, enclosures and other high-precision battery components.

Purpose-built
for EV batteries.

This is what FlareLaser was designed for: joining the delicate, highly conductive materials inside an Lithium-Ion battery pack without damaging the cell.

BUSBAR CELL CELL CELL CELL CELL
  • Cell tab weldingCopper, nickel, aluminum and sigma-clad tab materials, welded cleanly at the low heat input battery chemistry needs.
  • Cell-to-busbar & busbar-to-terminalConsistent, spatter-free joints across cylindrical, prismatic and pouch cell formats.
  • Module & pack interconnectsRepeatable welds built for gigafactory-scale production lines, not one-off samples.
  • No spatter, no contaminationFocused laser energy keeps debris off the cell and surrounding electronics - critical inside a sealed pack.

Also built
for the wider shop.

The same laser platform that welds battery cells scales to other precision metal joining work.

Automotive

High-volume metal components, assemblies and robotic production processes.

Industrial

Precision joining for equipment, fabricated components and engineered assemblies.

Electronics

Small, controlled welds where thermal distortion and repeatability are critical.

Aerospace

High-value components requiring controlled energy delivery and consistent process quality.

Custom Automation

Application-specific machines combining laser, robotics, vision, motion and controls.

Engineering
that works.

We start with the weld, then engineer the machine around it-process, optics, motion, tooling, controls, safety and production requirements.

PRECISION

Focused Energy

Laser welding concentrates energy at the joint, enabling controlled heat input and precise weld geometry.

INTEGRATION

One System

Laser source, optics, robot/CNC motion, sensing, PLC, HMI, safety and fixtures engineered together.

SUPPORT

Application First

Process development, sample welding, machine engineering and production support from concept through deployment.
