Fiber laser producer IPG Photonics has introduced new dual-beam fiber laser sources and automated laser systems for EV battery welding.

The Adjustable Mode Beam (AMB) laser source can achieve 3 kW single-mode laser beam in the core for spatter-free battery welding at double the speed of lower core powers, according to the company. The configurable AMB dual-beam lasers stabilize the weld pool with a secondary ring beam and single-mode core, minimizing spatter, cracking and porosity to achieve the weld penetration battery manufacturers require with a reduced heat-affected zone (HAZ). 

IPG also offers EV-Cube and LaserCell automated battery laser welding systems. EV-Cube is a gantry-based laser system capable of welding 10 cylindrical cells per second with 25 µm accuracy, and LaserCell is a 6-axis robotic laser system that welds prismatic, cylindrical and pouch modules.

These systems ship with a choice of IPG laser, process head, robot and tooling configurations, part handling and loading, integrated software, and IPG programming and process development. They can be equipped with real-time laser weld measurement to directly measure every weld as it is made to meet the required specifications.

“IPG’s lasers and laser systems provide solutions that directly address real-world requirements like battery welding and integrate patented technologies such as real-time laser weld measurement,” said Trevor Ness, IPG’s SVP of Worldwide Sales and Strategic Business Development.
