Laser welding issue

Perhaps the auxiliary gas is not pure enough, or the optical path has shifted

In fact, the protective lens of the laser welding machine itself is a consumable material, so it needs to be replaced regularly. However, due to factors such as process/method/setting, it may be damaged due to slag reflection. In rare cases, abnormal laser output and other factors can also easily cause the protective lens of the laser welding machine equipment to be burned out during use.

1. Consider whether the auxiliary gas we blow is pure. Whether the compression meets the standards. If air is being blown, the quality of compressed air needs to be checked.

2. Then it is necessary to check whether there is any deviation in the optical path during the laser emission process, and whether other lenses are damaged during operation.

3. Then, it is necessary to check whether the applicable nozzle aperture is too large.

4. Finally, check if the software's timing configuration for perforation blowing is reasonable.

When welding aluminum and galvanized sheet, this material is more prone to damaging the lens than other materials, and minimum power welding should be used

In order to prevent improper use of laser welding machine equipment from causing frequent damage to protective lenses, we can pay attention to the following issues to extend the service life of laser welding machine protective lenses.

1. Increase the air pressure appropriately, usually with a flow rate of no less than 15 and a pressure of no less than 4. It is recommended to use an oxygen pressure gauge of no less than 2 kilograms

2. When welding, try to weld the gun at a 45 ° angle to the plate, not perpendicular;

3. Set parameters as slowly as possible, with a delay of 200-500ms for opening/closing air, 20% for opening/closing light power, and a gradual time of 200-300ms for opening/closing light

Try replacing the F200 focusing lens and lengthening the wide scale tube to reduce splashing
