After the fiber output is collimated and focused, the fiber laser performs multi-faceted or multi-point welding on the weldment, which has the advantages of good beam quality, uniform and small spot, and easy installation and movement. In addition, the focal surface floating of the concentrated beam is caused by the change of beam form caused by the thermal lens effect of the laser, which is effectively suppressed after fiber transmission, making the welding quality stable and the weld quality significantly improved. The all-fiber basic structure design and sturdy metal shell ensure that this compact laser system can be used in online industrial production environments and has good protection against shock, dust, vibration and large-scale temperature changes. Conventional lasers are composed of lenses, laser rods, lenses, etc. In contrast, fiber lasers are a device that integrates all materials. A doped active optical fiber several meters long replaces the laser rod, and other components are also replaced by optical fiber devices. The various parts are closely connected together to form a laser resonator. The direct advantage of this design is that after installing the laser, there is no need for alignment, calibration, and subsequent surface cleaning of the optical lens, which means that there is little or no foundation for later maintenance.
