Optical fiber transmission laser welding machine is an upgraded version of YAG/lamp pump/hard optical path laser welding machine. It couples high-energy laser beam into optical fiber. After long-distance transmission, it is collimated into parallel light by a collimator and then focused on the workpiece. A laser welding equipment for welding.

Optical fiber transmission laser welding machine can be divided into two types: energy feedback (high configuration) and current feedback (low configuration).

It belongs to the pulse laser welding machine. The biggest advantage of pulse laser welding is that the overall temperature rise of the workpiece is small, the heat influence range is small, and the deformation of the workpiece is small.

The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece and diffuses into the material through heat conduction. The waveform, width, peak power and repetition frequency of the laser pulse are controlled to melt the workpiece and form a specific molten pool, thereby making the workpiece A good connection is formed between them.

System principle: An energy detection device is added to the output of the laser to detect the size of the output laser energy, and the signal is fed back to the control system in real time, and compared with the set theoretical energy to form a closed-loop control system. To achieve the purpose of accurately controlling the laser energy output.
