The role of laser welding filters in fiber laser welding

Laser welding filters– Generally speaking, the laser welding machine we often refer to should be attributed to current feedback laser welding. The principle of fiber optic transmission energy negative feedback laser welding machine is different in that an energy detection device is added at the output end, which can be used to detect the amount of energy excited by the laser welding plan light sheet and provide real-time feedback of the signal of laser energy to the control end, Compare with the theoretically set energy to form a closed-loop control system, achieving accurate control of laser energy output.

The fiber laser is filtered by a fiber laser welding filter and output. After being focused by a calibration lens, it can weld multiple surfaces or points of the welded component, which has the advantages of good beam quality, uniform and small light spots, and convenient installation and movement. The fluctuation of the focal plane of the focused beam caused by the change in beam mode caused by the thermal lens effect of the laser is effectively suppressed after transmission through the optical fiber, ensuring the stability of welding quality and significantly improving the quality of the weld seam. The all-fiber infrastructure design and sturdy metal casing ensure that this compact laser system can be suitable for online industrial production environments, and has good protective capabilities against large-scale changes in impact, dust, vibration, and temperature. Traditional lasers are composed of components such as filters, laser rods, and optical lenses. Fiber optic transmission energy negative feedback laser is a device that integrates all materials
