Maintenance of Laser Welding Equipment
Visual Inspection
You need to check your laser welding equipment every day before you start working. Look at the protective lens for dust, oil stains, splashes, or burn marks. Check the copper nozzle for blockages or signs of wear. Every week, clean the air inlet and outlet filters to remove dust. Inspect all cables for damage or wear.
Tip: Place a clean white sheet of paper about 200–300 mm from the nozzle. Watch the red light spot on the paper. If you see a regular shape, uniform brightness, and sharp edges, your lens is clean. If you notice black spots, dark areas, or odd shadows, your lens may be contaminated.
Make sure the surface of the material is clean before welding. Use acetone to remove grease and oil. Scrub off rust, scale, or coatings with a wire brush. Confirm that the material is dry. Always check critical parts for damage or misalignment. These steps help you catch problems early and keep your equipment working well.
Cleaning Gas Outlet Tubes
Gas outlet tubes play a big role in the maintenance of laser welding equipment. Moisture can enter the welding process from humidity, dirty gas lines, or poorly stored parts. When moisture gets inside, it can cause gas pockets, cracks, and weak welds. Too much hydrogen can make the weld brittle and cause sudden failure.
- Porosity and gas pockets can form inside the weld.
- Cracks may appear long after welding, which can be dangerous.
- Welded joints can become stiff and break easily.
- The weld may look bad and have weak spots.
Clean the gas outlet tubes often to prevent these problems. Make sure the tubes are dry and free from dirt. This keeps the shielding gas stable and helps you get strong, clean welds.
Cleaning External Surfaces
You need to keep the outside of your laser welding equipment clean. Dust and dirt can build up on the machine and in your workspace. Wipe down the surfaces with a soft cloth. Clean the area around the equipment to make sure air can flow freely. Good ventilation helps prevent overheating and keeps the equipment safe.
Note: A clean workspace makes it easier to spot leaks, damage, or other issues. It also helps you work safely and keeps your equipment in good shape.
Regular cleaning is a key part of the maintenance of laser welding equipment. When you keep everything clean, you avoid problems and help your equipment last longer.

Taking care of your cooling system is very important. It helps your laser welding equipment work well and last longer. The cooling system stops the machine from getting too hot. If you do not take care of it, your machine can break. Your welds may not look good.
Check Coolant Levels
Coolant takes away heat from the machine. This keeps the temperature safe. You need to look at the coolant before every shift. If there is not enough coolant, the machine can get too hot and stop.
Tip: Always use the coolant the maker says to use. The wrong coolant can block or damage the system.
If you use your laser welding equipment with low coolant, you can have problems:
- The laser may not be as strong, so welds are weak.
- Welds can have holes, cracks, or not go deep enough.
- The machine may break more often and cost more to fix.
Inspect for Leaks
Leaks in the cooling system can make coolant go away. This can make the machine too hot. You should look for leaks often. There are many ways to find leaks:
| Method Type | Description |
|---|---|
| Indirect Leak Detection | Watch how the system works to find leaks without touching coolant. |
| Differential Pressure Monitoring | Check for pressure drops to see if there are leaks. |
| Coolant Reservoir Level Sensors | Look for changes in fluid levels to spot slow leaks. |
| Temperature and Flow Rate Analysis | Watch for changes in temperature or flow. |
| Direct Leak Detection | Look at the coolant to see if there are leaks. |
| Leak Detection Cables and Ropes | Use special cables that sense leaks when they get wet. |
| Optical and Conductivity Sensors | Use special tools to find liquid where it should not be. |
| Acoustic Emission Leak Detection | Listen for sounds that mean there is a leak. |
Drain Water Cooler in Winter
Cold weather can freeze water in the cooling system. Frozen water can break pipes and hurt your machine. You should empty the water cooler and turn off the machine before winter.
- Turn off the power to the laser and chiller.
- Open the drain and let the water come out.
- Use air to blow out any water left inside.
- Close the water inlets and outlets with rubber plugs to keep out dust.
Note: Clean the water tank and filters after you drain them. This stops dirt from building up when you use the machine again.
Calibration and Alignment
Laser Alignment
It is important to check the alignment often. Good alignment helps you make strong welds. If the laser beam misses the spot, welds can look uneven. Weak joints can happen if the laser is not lined up. Watch for odd weld shapes or results that do not match. Keeping the laser aligned helps you avoid mistakes and saves time.
Tip: Try using a test piece before starting a new project. This lets you find problems early.
Routine Calibration
Routine calibration helps your machine work well. You need to set the laser power, focus, and alignment right. Calibration stops defects and makes welds better. Follow a schedule based on how much you use your equipment. The materials you use also matter.
