Familiarize yourself with the various components of your QILIN Laser Welding Gun Parts. Refer to the images below for visual identification.

4. Setup and Installation

This section outlines the general steps for installing and setting up the laser welding gun parts. Specific procedures may vary depending on the exact model and configuration of your laser welding head (BWT20, DWT20, etc.). Always refer to the main laser welding machine's manual for detailed assembly instructions.

1. Prepare the Work Area: Ensure a clean, well-lit, and safe environment. Disconnect power from the laser welding machine.
2. Identify Components: Unpack all parts and identify them using the "Parts Identification" section.
3. Install Fixed Plates and Fixtures:
   • Attach the appropriate fixed plate (e.g., BWT20 fixed plate, 1-Axis fixed plate, 2-Axis fixed plate) to the welding gun head using the provided screws.
   • Mount any required fixtures (e.g., 1-Axis Fixture, 2-Axis Fixture) securely.

   

4. Assemble Wire Feeding Mechanism (if applicable):
   • Attach the wire feeding fixture to the designated mounting points.
   • Ensure all screws and nuts (e.g., nut, screw1, screw2) are tightened appropriately to secure the mechanism.

5. Install Optical Components:
   • Carefully place the protective lens (e.g., Protective Lens 20x2, AR/Coated Laser Protective Windows D20-T2) and reflector lens (e.g., Reflector Lens 15.2, Reflector Lens 22.5) into their respective positions.
   • Secure them with the pressing ring (e.g., QILIN Protective Lens Pressing Ring) and lens base, ensuring they are clean and free of dust.
   • Install any necessary tubes (e.g., 65mm Tube, 73mm Tube, BWT21 F200 Tube) and sealing rings.
6. Connect Electrical Components:
   • Connect the motor and switch assembly (e.g., switch assembly, switch button) according to the wiring diagram provided with your specific laser welding head.
   • Ensure all connections are secure and properly insulated.
7. Install Airflow Rings: Attach the appropriate airflow ring (e.g., 1-Axis airflow ring, 2-Axis airflow ring) to ensure proper gas flow during welding.

5. Operating Instructions

Once all components are correctly installed, you can proceed with operating the laser welding gun. Always follow the operating procedures outlined in your main laser welding machine's manual.

1. Pre-Operation Checks:
   • Verify all parts are securely fastened.
   • Check optical components for cleanliness and damage.
   • Ensure proper gas supply and pressure for the airflow rings.
   • Confirm electrical connections are sound.
2. Power On: Turn on the laser welding machine according to its manufacturer's instructions.
3. Parameter Setting: Adjust welding parameters (laser power, pulse width, frequency, welding speed, wire feed speed) on the main machine's control panel as required for your specific application.
4. Welding Operation:
   • Position the welding gun head correctly over the workpiece.
   • Activate the laser and wire feed (if used) using the gun's switch button or foot pedal.
   • Maintain a consistent welding speed and distance for optimal results.
5. Post-Operation:
   • Turn off the laser and wire feed.
   • Power down the laser welding machine.
   • Allow the gun head to cool before handling.

6. Maintenance

Regular maintenance is crucial for the longevity and performance of your QILIN Laser Welding Gun Parts.

• Daily Checks:
  • Inspect protective lenses and reflector lenses for dust, debris, or damage. Clean or replace as necessary.
  • Check nozzles and airflow rings for blockages.
  • Ensure all screws and connections are tight.
• Cleaning Optical Components:
  • Use only specialized optical cleaning solutions and lint-free wipes.
  • Gently wipe the lens surfaces; avoid excessive pressure.
  • Replace scratched or damaged lenses immediately to prevent laser damage.

  

• Wire Feeder Maintenance:
  • Clean the wire guide and contact tip regularly to prevent wire feeding issues.
  • Replace worn contact tips and nozzles as needed.
• Insulation Boards: Inspect insulation boards (e.g., DWT20/22/23 Insulation Board) for signs of wear or damage and replace if compromised to maintain electrical safety.

7. Troubleshooting

This section addresses common issues you might encounter. For more complex problems, consult a qualified technician or the manufacturer.

8. Specifications

The following are general specifications for QILIN Laser Welding Gun Parts. Specific dimensions and materials may vary by component type (e.g., lens, tube, fixture).

9. User Tips

• Always keep spare protective lenses and nozzles on hand, as these are consumable items that require frequent replacement for optimal weld quality.
• When replacing optical components, ensure the work area is dust-free to prevent contamination that could affect laser performance.
• For precise wire feeding, regularly check the alignment of the wire guide and ensure the wire spool is correctly tensioned.
• If experiencing inconsistent welding, first check the gas flow and the cleanliness of the airflow ring and nozzle before adjusting laser parameters.
