Fiber Laser Welding


The FLW takes laser welding to a higher level of precision and productivity. AMADA’s ENSIS fiber laser technology provides Process Range Expansion (PRE) by ensuring precise, high-speed results even when processing reflective materials such as brass and copper. The FLW is equipped with a patented rotating lens. With this unique 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. Additional features of the new FLW include:

  • Automatic Beam Focus — Adjusts the focus lens to an optimum setting based on the set welding conditions

  • Welds reflective materials such as brass and copper

  • Beam weaving by lens rotation versus robot axis rotation produces fast, accurate and smooth results

  • Teaching Assist System (TAS) — Uses a CCD camera to accurately compensate for any deviation from the targeted welding path

  • AMADA’s FLW-CAM software improves user efficiency through offline robot teaching — simulating movements based on 3D data

  • A large reduction in electricity costs is made possible due to a high heat exchange efficiency. Maintenance cycles are also improved due to the reduction of mirrors and other optical components


  • Variable Beam Control (ENSIS technology)

  • Z-Indicator

  • Continuous Waveform (CW) welding
