1) In order to ensure that the automatic laser welding machine has been in normal working condition, after two consecutive weeks of work or stop using a period of time, in the boot before the first YAG rods, dielectric diaphragm and lens protection glass and other optical components in the inspection, To determine the optical components without dust pollution, mildew and other anomalies, if the above phenomenon should be promptly treated to ensure that the optical components will not be damaged under strong laser irradiation. (If the use of the equipment environment is relatively clean, the inspection can be extended to a month or even longer)
2) The purity of cooling water is the key to ensure the laser output efficiency and the life of the laser condenser chamber. The conductivity of the inner circulating water should be checked once a week to ensure that its conductivity is 30.5MW · cm and must be changed once a month. Circulating deionized water, the conductivity of the new injected pure water must be 32 MW · cm. Always observe the color change of the ion exchange column in the cooling system. Once the color of the resin in the column is changed to dark brown or even black, the resin should be replaced immediately.
