IPG launches a new dual beam laser with the highest single mode core power
From September 12th to 14th, 2023, IPG Photonics, a renowned fiber laser technology leader in the United States, will showcase its latest innovative laser solutions at the Battery Show in Michigan, USA. At that time, IPG will also showcase industry-leading fiber laser sources and automated laser systems for electric vehicle battery welding applications.
New laser technology has increased the limit of battery welding speed
IPG will continue to expand its dual beam fiber laser product and introduce a new tunable mode beam (AMB) excitation source. This laser source can achieve a single mode laser beam of 3kW in the core, which is the industry's first. The increase in single mode power provides unprecedented speed and productivity improvement for battery welding, and the spatter free welding speed is twice faster than low core power.
This AMB dual beam laser utilizes a secondary annular beam to work in series with a single mode core to stabilize the welding pool and almost eliminate welding 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 various welding applications.
Battery manufacturers typically prefer single-mode fiber lasers for precision welding applications, as they can concentrate power on extremely small spot sizes on the parts. The resulting high energy density easily overcomes the high reflectivity of metals such as copper and aluminum, while achieving the required welding penetration at an extremely fast speed and reducing the heat affected zone (HAZ).
IPG is not just a laser enterprise, "said Trevor Ness, Senior Vice President of Global Sales and Strategic Business Development at IPG." IPG's lasers and laser systems aim to provide solutions that directly meet real-world needs such as battery welding, and integrate patented technologies such as real-time laser welding measurement to provide 100% welding quality assurance
An automated laser system designed for mass battery production
IPG will bring two on-site demonstrations of an automated turnkey laser welding system specifically designed for battery welding applications.
EV Cube ™ Automatic battery laser welding system: A gantry based laser system designed to meet the demanding speed and accuracy requirements of battery module welding. Using proprietary laser welding programming, the EV-Cube can be configured to provide welding speeds of up to 10+cylindrical units per second while maintaining 25 μ The accuracy of m.
LaserCell ™ Battery Welding System: It is a robotic laser system that provides the flexibility and coverage required for large or complex battery modules. The system adopts a 6-axis robot that can be configured to weld prismatic, cylindrical, and bag shaped modules while maintaining high production and short cycle time.
These systems are equipped 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 welding measurement, using patented IPG technology to directly measure each weld seam, ensuring that only welds that meet the required specifications can enter the final product stage.
