Fiber laser system features rotating lens for welding
Amada offers the FLW 4-kW fiber laser system. The laser beam has a wavelength that is about one-tenth of that emitted by a conventional CO2 laser, helping to ensure high-speed results even when processing reflective materials, such as brass and copper, and combinations of dissimilar materials that traditionally are difficult to weld.
With the machine’s patented rotating lens, the laser beam no longer is aligned with a specific point along the target path; instead it circles within a small area as it is welding. The rotating lens makes it possible to bridge larger and uneven gap sizes while producing a clean, even weld, states the company.
The heat input into the material also is optimized to produce precisely defined weld edges with almost no unnecessary deposits of material. This capability reduces or eliminates the need for secondary finishing.
The NC Auto Focus Control feature adjusts the focus lens to an optimum position based on the welding conditions set on the AMNC/PC Control. This feature outputs automatically a narrow beam for welding and a wider beam to weld radius corners.
