Laser welding machine simple debugging four steps


The adjustment of the laser welding machine must be carried out by specially trained personnel, otherwise it will damage the other components on the optical path due to the laser misalignment or deviation. The steps of adjusting the laser resonator are as follows:

1, check the reference light source: red semiconductor laser (www.laser5.org) is the basis of the entire optical path, must first ensure its accuracy.

2, adjust the output mirror (output media diaphragm) position: adjust the output mirror, should be equipped with YAG rod condenser cavity removed, so as to avoid the optical path YAG rod refraction bias affect the accuracy of the adjustment. The exact location of the output media diaphragm should be the center of the red light at its center and the red light can be reflected back to the red light, otherwise it should be carefully adjusted by the knob of the diaphragm holder.

3, check the YAG stick installation position: with a transparent adhesive tape were attached to both ends of the YAG rods, observe whether the red light spot in the middle of the two rods, if any deviation should be adjusted by the condenser chamber Position to be corrected.

4, check the shutter position: manually rotating the lens holder, the shutter will be pushed to the light blocking position to observe whether the red light in the middle of the lens, the reflected light is located in the center of the beam end of the absorption cone, such as the location is not Correct and can be slightly adjusted, and finally, should pay special attention to carefully check the shutter lens is clean, contaminated lenses will soon burst in use. At this point the laser welding machine part of the adjustment work is completed.
