Specification and maintenance of industrial laser welding machines

Industrial laser welding machines are available in different specifications. The following chart shows some of the common specifications to help choose the right machine for welding needs.

Laser welding machines are highly durable, but they need maintenance to work optimally. Here are some essential maintenance tips for industrial laser welding machines:

• Cleaning

Cleaning the machine, especially the work area and optical components, is one of the most important maintenance routines. Laser welding machines are only as good as the optics used in them. Contaminated or dirty optics can cause issues like inconsistent welds, shortened lifespan of the laser machine and damage to workpieces. Optical cleaning should be done with proper equipment using the right technique. It is also important to use compressed air to blow away dirt and dust before cleaning the optics to avoid scratching them.

• Coolant system maintenance

Most laser welding machines have a coolant system that helps to regulate the temperature of the laser and prevent overheating. Check and maintain the coolant system regularly to ensure it's functioning well. It's important to monitor the coolant levels and top off when needed. Also, test the coolant to check for contamination and ph levels and replace it when necessary to prevent damage to the laser.

• Cleaning the exhaust system

Most laser welding machines are designed with exhaust systems to remove fumes and contaminants generated during the welding process. It's important to clean and inspect the exhaust system regularly to ensure optimal performance. Check the hoses and filters for any blockage or buildup and clean them as needed. Also, inspect the exhaust fans and make sure they are working well to avoid overheating of the machine.

• Optical alignment and calibration

It's important to regularly calibrate and align the optics of the laser welding machine for optimal performance. Optical misalignment can cause poor weld quality and inconsistent performance. Follow the manufacturer's recommendations when calibrating the lasers and align the optical components to ensure high precision welding.

• Regular inspections

It's important to regularly inspect the laser welding machine to check for any signs of damage or wear. Look for any loose screws or bolts and make sure all the components are well secured. Inspect the electrical connections and ensure they are well connected. Also, test the safety features of the machine, including emergency stops and interlocks.
