Technical content

The ARM FL series of industrial, multi-kilowatt fiber lasers includes beam management to deliver superior results in a variety of challenging welding tasks. The ARM technology features two individually controllable, co-axial beams from a single fiber, providing a new level of flexibility for applications such as zero-gap welding of zinc-coated steel, as well as the ability to weld aluminum without filler wire, with minimal spatter, and no hot cracking. The power levels in both central spot and surrounding ring are independently adjustable. This results in high speed and high throughput spatter-free processing and lowers overall production costs by largely eliminating the need for post-processing. To maximize operational flexibility, ARM FL products are equipped with either a Fiber-Fiber-Switch (FFS) or Fiber-Fiber- Coupler (FFC).
