Amada has developped a new FLW 4000 M3 fiber laser welder. The laser, offers electrical savings and high-speed, high-precision welding. The FLW uses a 4kW fiber engine to produce a laser beam with a wavelength that is approximately one-tenth of that emitted by a conventional CO2 laser.
This innovative feature results in Process Range Expansion (PRE) by ensuring precise, high-speed results even when processing reflective materials such as brass and copper — and combinations of dissimilar materials that were previously difficult to weld.
The FLW is equipped with a patented rotating lens. With this feature, the laser beam is no longer aligned with a specific point along the target path — instead it circles within a small area as it is welding.
A rotating lens makes it possible to bridge larger and uneven gap sizes while producing a clean, even weld. The heat input into the material is also optimized and results in precisely defined weld edges with virtually no unnecessary deposits of material. This capability reduces, or often eliminates the need for secondary finishing.
