How long is the period for replacing the deionized water of the laser welding machine, and how to judge whether it needs to be replaced? The laser is the core component of the laser welding machine. If it has a problem, the whole machine will not work, so the maintenance of the laser is very important. To maintain the laser well, we must first ensure that the chiller closely related to it must replace the deionized water regularly as required. Because the purity of the cooling water is the key to ensuring the life of the laser focusing cavity components and the laser output and welding effect.

The specific inspection method of deionized water is: set the multimeter to the 2MW resistance range, and insert the exposed metal parts of the two probes at the measuring end into the cooling water surface in parallel with a distance of 1cm. The resistance reading at this time should be at least greater than 250kW. If the reading is lower than this value, the cooling water should be replaced immediately. The conductivity of the newly injected pure water must be 32MW/cm. First of all, in principle, the deionized water in the internal circulation of the chiller must be replaced once a month. However, in actual operation, the conductivity of the internal circulating water should be checked at least once a week to ensure that its conductivity is 30.5MW/cm.

When we use the laser welding machine in normal times, we should pay attention to whether there is frost on the titanium tube of the chiller. If frost occurs, it may be caused by insufficient Freon in the refrigeration system. You should immediately ask relevant professionals to replenish it and check for leaks.
