Introducing HighLightTM FL-ARM with Fiber-Fiber-Switch

18 November 2019

The new Coherent HighLightTM FL-ARM with Fiber-Fiber-Switch is a high-power (2 8 kW), dual fiber output laser that can sequentially power two separate workstations or processes. Dual fiber output delivers increased throughput in cost-sensitive, high-volume welding applications, particularly in automotive manufacturing, such as welding of doors, hang-on parts, ultra-high strength steel components, and aluminum body frames.

HighLight FL-ARM implements power-sharing through the use of Coherent’s proprietary Fiber-Fiber-Switch technology. The process fibers themselves utilize Coherent’s unique Adjustable Ring Mode configuration, comprising a dual-core delivery fiber that produces a central spot surrounded by another concentric ring of laser light. The power levels in the center and the ring can be independently adjusted on demand and switched at a rate 1000 times faster than competing products; it can also be independently modulated. This arrangement provides improved control of keyhole and melt pool stability during the welding process, leading to superior results. Added to this, HighLight FL-ARM employs a multi-stage back reflection immunity system that enhances laser reliability and lifetime, and enables safe processing of highly reflective materials, including brass, copper, and aluminum.
