IPG Introduces New Dual-beam Laser With Highest Single-mode Core Power

From September 12 to 14, 2023, IPG Photonics, a leading US fiber laser technology leader, will showcase its latest innovative laser solutions at the Battery Show in Michigan, USA. IPG will also be showcasing its industry-leading fiber laser sources and automated laser systems for electric vehicle battery welding applications.
New Laser Technology Pushes the Limits of Battery Welding Speed
IPG will continue to expand its dual-beam fiber laser offerings with a new Adjustable Mode Beam (AMB) laser source. This laser source is capable of a 3kW single mode laser beam in the core, an industry first, and the increase in single mode power provides unprecedented speed and productivity gains in battery welding, with spatter-free welding up to two times faster than low core power.
This AMB dual-beam laser utilizes a secondary ring beam working in tandem with the single-mode core to stabilize the weld cell, virtually eliminating weld defects such as spatter, cracking, and porosity.IPG AMB lasers can be configured with a wide range of beam parameters to provide optimized performance in a variety of welding applications.
Battery manufacturers often prefer single mode fiber lasers for precision welding applications because of their ability to focus power on very small spot sizes on the part. The resulting high energy density easily overcomes the high reflectivity of metals such as copper and aluminum, while achieving the desired weld penetration at very high speeds and reducing the heat affected zone (HAZ).
"IPG is more than just a laser company," said Trevor Ness, Senior Vice President of Global Sales and Strategic Business Development at IPG, "IPG's lasers and laser systems are designed to provide solutions that directly address real-world needs such as battery welding, and integrate real-time laser patented technologies such as weld measurement to provide 100% weld quality assurance."
Automated Laser Systems Designed for High Volume Battery Production
IPG will bring two live demonstrations of automated turnkey laser welding systems designed specifically for battery welding applications.
EV-Cube™ Automated Battery Laser Welding System: A gantry-based laser system designed to meet the demanding speed and accuracy needs of battery module welding. Using proprietary laser welding programming, the EV-Cube can be configured to deliver welding speeds of up to 10 + cylindrical cells per second while maintaining 25 μm accuracy.
LaserCell™ Cell Welding System: is a robotic laser system that provides the flexibility and coverage needed for large or complex cell modules. The system utilizes a 6-axis robot that can be configured to weld prismatic, cylindrical, and pouch shaped modules while maintaining high throughput and short cycle times.
These systems come complete with IPG lasers, process heads, robot and tool configurations, part handling and loading, integrated software, and IPG programming and process development. These systems can be equipped with real-time laser weld measurement to directly measure each weld using patented IPG technology, ensuring that only welds that meet the required specifications make it to the final product stage.
