一、设备清洗

1、 Equipment cleaning

每次工作前后，作好环境清扫，使地面干燥，洁净。再作好YAG激光焊接机设备的清洁，包括机箱的外表面，观察系统，工作台面等要无杂物，洁净。防护镜片需保持干净。

Before and after each work, first clean the environment to make the ground dry and clean. Further clean the YAG laser welding machine equipment, including the outer surface of the chassis, observation system, and workbench, to ensure that there are no debris and cleanliness. Protective lenses should be kept clean.

二、冷却检查

2、 Cooling inspection

冷却系统的维护，主要是定期检查冷却水质，若水质变差、混浊、透明度变差，应及时更换新水。定期检查水箱内的存水量，若存水量不足应及时添加。本系统建议使用去离子水或纯净水。

The maintenance of the cooling system mainly involves regular inspection of the cooling water quality. If the water quality deteriorates, becomes turbid, or the transparency deteriorates, it should be replaced with new water in a timely manner. Regularly check the water storage capacity in the water tank, and if the storage capacity is insufficient, add it in a timely manner. It is recommended to use deionized water or purified water for this system.

定期检查各水管接口处是否有漏水，有漏水则拧紧该处螺丝不漏水。当氙灯和激光棒与腔体的封接处漏水时，主要原因是橡胶密封圈变形或老化，在拧紧螺丝后依然漏水，应仔细检查橡胶圈，若已失效，则更换备用橡胶圈。

Regularly check if there is any leakage at the interface of each water pipe, and tighten the screws at that location until there is no leakage. When there is water leakage at the sealing point between the xenon lamp and laser rod and the cavity, the main cause is deformation or aging of the rubber sealing ring. After tightening the screws, the water still leaks. The rubber ring should be carefully checked, and if it has failed, replace the spare rubber ring.

三、检查激光焊接机光路组件

3、 Check the optical path components of the laser welding machine

为了保证激光焊接机激光器一直处于正常的工作状态，连续工作后或停止使用一段时间时，在开机前应对YAG棒、介质膜片及镜头保护玻璃等光路中的组件进行检查，确定各光学组件没有被污染、如有污染现象应及时进行处理，保证各光学组件不会在强激光照射下损坏。

In order to ensure that the laser welding machine laser is always in normal working condition, after continuous operation or when it is stopped for a period of time, the components in the optical path such as 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.

四、检查调整激光器谐振腔

4、 Check and adjust the laser resonator

设备操作人员可以经常用黑色像纸检查激光器输出光斑，一旦发现光斑不均匀或能量下降等现象，应及时对激光器的谐振腔进行调整，确保激光输出的光束质量。调试操作人员必须具备激光防护的常识，工作中必须佩带专用激光防护眼镜。激光器的调整必须由经过专门培训的人员进行，否则会因激光器失调或调偏造成光路上其它组件的损坏。

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 in a timely manner 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.
