Laser welding machine maintenance should be carried out by specially trained personnel, otherwise it is easy to have serious damages.
1) in order to guarantee the normal work of the laser welder, it should be stopped using for a period of time after two-week continue work. Before start the machine, people should check up the YAG rods, medium diaphragm and protect glass of lens in the optical path components , determine to make sure the optical components without dust pollution(if the use environment of equipment is clean, the inspection period may be extended accordingly to a month or more)
2) cooling water condenser is the key element to guarantee the purity of the laser output efficiency and laser cavity component. So, people should check the circulating water conductivity once a week to ensure the electrical conductivity of 30.5 MW · cm and must be replaced circulate in deionized water every month. Watch the cooling system momentarily and the color change of the ion exchange. Once the color of the resin in exchange column into a dark brown or black, resin should be replaced immediately.
3) welding equipment operators can often use black paper to check the laser output spot examination. Once found flare phenomenon such as uneven or energy decline, should timely adjust the laser cavity in order to make sure the laser output beam quality.
