Various industries have already taken action to regard automated laser welding machine technology as a strategic goal, and laser welding machines have become standard equipment for some high-end industrial production and processing enterprises. So, how should we maintain and maintain laser welding machines during their use?
1. Check the optical path components of the laser welding machine.
To ensure that the laser welding machine’s laser is always in normal working condition, after continuous operation or when it is stopped for some time, the components in the optical path such as the YAG rod, dielectric film, and lens protection glass should be inspected before starting up, to ensure that each optical component is not contaminated. If there is any pollution, it should be promptly treated to ensure that each optical component will not be damaged under strong laser irradiation.
2. Check the conductivity of the internal circulating water.
The purity of laser cooling technology for cooling water is the key to ensuring laser output efficiency and the lifespan of laser cavity components. During use, the conductivity of the internal circulating water should be checked weekly to ensure its conductivity. The deionized water in the internal circulation must be replaced once a month. Always pay attention to the color changes of the ion exchange column in the cooling system. Once the color of the resin in the exchange column becomes dark brown or even black, the resin should be replaced immediately.
3. Check and adjust the laser resonator.
Equipment operators can frequently check the output spot of the laser using black imaging paper. Once any uneven or decreased energy spot is found, the resonant cavity of the laser should be adjusted promptly to ensure the quality of the laser output beam. Debugging operators must have common knowledge of laser safety protection and must wear specialized laser protective glasses during work. The adjustment of the laser must be carried out by specially trained personnel, otherwise, it may cause damage to other components on the optical path due to laser misalignment or bias adjustment.
