When the laser power of the welding machine gradually declines, the following critical components may need to be replaced or repaired:
Lenses: including protective lenses, focusing lenses or reflectors, which need to be cleaned or replaced regularly if contamination or damage is found.
Cooling system components: Check cooling channels, water pumps, water coolers and other components to ensure cooling efficiency, and repair or replace them if necessary.
Lasers: If the laser is aging or has been operating for too long, you may want to consider replacing it with a new one.
Fiber Optic Connector: Check whether the fiber connector or the fiber itself is damaged, and replace it if there is a problem.
Power module: Check the stability of the power supply and replace the power module if there is any abnormality.
Control system: Make sure the control system is set up correctly and recalibrate or replace the control system if necessary.
If there is any failure or aging of the above parts, it may lead to the degradation of the laser power of the welding machine, and it is recommended to seek professional and technical personnel to assist in overhauling or replacement.
