Amada’s (Buena Park, CA) Fiber Laser Welder (FLW) 3000 ENSIS is a complete welding system designed to use minimal heat on the weld zone to improve productivity and weld quality.
The system is equipped with a patented rotating lens, resulting in the laser beam no longer being aligned with a specific point along the target path. Instead, the beam circles within a small area as the system is welding. The rotating lens improves filler feeding and aluminum welding and 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 improves edge definition.
The ENSIS 3000 fiber laser engine contains a Variable Beam Control Unit that automatically adjusts the laser beam’s properties to process a wide range of material thicknesses. 3 kW of power is generated with a single module, eliminating the need for a combiner and reducing overall power consumption. The new, simplified design uses fewer overall components than any of Amada’s previous models and does not require laser gas or mirrors.
The wire feed system enables the machine to switch from fusion welding to adding filler wire all in the same program. The adaptive filler control uses a pull shaft motor to evenly bridge gaps on larger weld surfaces. It can close corners and remove gaps by fusing 15% of the material thickness or add up to 25% filler for a smoother weld.
Any robot deviations from the actual weld path can be adjusted accurately by utilizing TAS (Teaching Assist System) on the system’s AMNC/PC Control. By using a CCD camera, new target points are selected which instantly teach the welding robot the correct target path. All compensation points are stored with the part program for future production.
Height position and welding points can be directed with the cross target during teaching setup to ensure a precise weld. The operator can monitor the distance of the torch and can adjust its position to prevent material from overheating. The system also features Amada’s NC Auto Focus Control to adjust the focus lens to an optimum position based on the welding conditions set on the AMNC/PC Control. This feature increases productivity by automatically outputting a narrow beam for welding and a wider beam to weld radius corners.
