How To Laser Clean With A Laser Welding Machine
Frequent viewers of our social media channels may have noticed that an increasing number of users have recently started choosing our 3 in 1 laser welding machine.
Although this equipment is primarily used for metal welding, we have upgraded it with an entry-level laser cleaning function. This allows many users to use the laser to pre-treat welding parts before welding or to clean the weld seam after welding, making the welding surface look cleaner.
To laser clean with a laser welding machine, we have to switch the laser machine to ‘laser clean’ mode.
Step 1. Switch laser welding machine to Laser Cleaning Mode
- Press the switch button in the top right corner of the HOME interface.
- Press ‘continue’ button.
- Power-off and restart the laser welding machine.
Step 2. After entering the laser clean mode, replace the appropriate focusing lens: Different models require different lenses, so please choose according to the provided guidelines.
Step 3. Remove the locking part in front of the laser torch.
Some models have locking screws:
– For the SUP23T laser torch, loosen the locking screw on the side to remove the collet.
– For the SUP21T laser torch, loosen the screws on the top cover to remove the collet.
Step 4. Settings for Laser Cleaning
- Scanning Frequency: Ranging from 10-100Hz. It is recommended to set it to 80.
- Scanning Width: The width of the laser spot scan, which depends on the lens specifications of your model. Please select the appropriate width in the system settings.
- Peak Power: Generally set to the maximum power of the laser.
- Duty Cycle: Default is 100%.
- Pulse Frequency: Default is 2000.
Step 5. Confirming the Focus
To confirm the focus, move the laser back and forth between near and far distances. The point at which the sound is loudest and the sparks are the most intense is the focus. At this distance, the cleaning will be the most effective as the energy is strongest. Use the following references based on the type of focusing lens you are using:
– F150 Focus: The optimal distance between the laser torch and the material is approximately 10-15 centimeters.
– F400 Focus: The optimal distance between the laser torch and the material is approximately 35-40 centimeters.
– F800 Focus: The optimal distance between the laser torch and the material is approximately 75-85 centimeters.
Use of Assist Gas
Assist Gas Selection for Cleaning: Air pressure should be no less than 3 kg, filtered to at least level 3 to ensure it is oil-free and moisture-free, or use other inert gases.
During cleaning, please maintain a steady distance between the gun head and the material, and keep a consistent hand speed.
