Here is how to maintain automatic laser welding machines effectively:
- Optics and Welding Head: The protective lens, focus lens, and nozzle should be checked daily for contamination, spatter, or wear. Clean the lenses with isopropyl alcohol and lint-free tissue, and replace them if scratched or discolored to prevent beam distortion or power loss.
- Cooling System: Most machines use water chillers to prevent overheating. Maintain coolant temperature between 22℃–26℃, top off with deionized water, and clean or flush the system monthly to prevent mineral buildup or algae growth that can damage the laser source.
- Shielding Gas System: Confirm that argon, nitrogen, or air flow is stable and at the correct pressure. Check hoses and fittings for leaks or blockages to ensure a clean weld environment and prevent oxidation or porosity.
- Mechanical Components: Lubricate the guide rails, ball screws, and robotic joints weekly. Inspect motion systems for unusual vibrations, backlash, or wear. Proper alignment and lubrication extend component life and maintain welding accuracy.
- Electrical and Control Systems: Check for loose connectors, worn cables, and abnormal heating in the control panel. Clean fans and filters to prevent dust accumulation. Test emergency stop buttons and safety interlocks monthly to ensure full compliance with laser safety protocols.
