Coherent (Santa Clara, CA) and II‐VI Incorporated (Saxonburg, PA) will partner to enable faster process development and streamlined production services for laser welding in automotive body-in-white applications and mass-production copper welding for electrification applications. II-VI’s advanced laser processing heads and Coherent’s Adjustable Ring Mode (ARM) fiber laser technology combine to produce welds with the high quality at a very high speed and over large working areas, increasing the efficiency and decreasing the cost of ownership.
Coherent will be a single point of contact throughout the development and deployment of welding subsystems combining the Coherent ARM fiber lasers and the II-VI RLSK and HIGHmotion 2D remote laser processing heads. Coherent will deliver an optimized, integrated solution with service that ensures maximum productivity on customers’ manufacturing lines.
II-VI’s laser processing heads, with advanced optics and smart software, enable the Coherent ARM laser to control, in real time, the beam shape and power distribution with great precision for remote laser welding.
The Coherent ARM laser and the II-VI remote laser processing heads are effective in suppressing back-reflections, enabling extremely high-quality welds in reflective materials such as aluminum and copper, which are nowadays widely used in e-mobility applications. They provide a constant laser power level up to 8 kW, which is beneficial for many copper and aluminum applications.”
