一、設備清洗

1、 Equipment cleaning

每次工作前后，作好環境清掃，使地面干燥，潔凈。再作好YAG激光焊接機設備的清潔，包括機箱的外表面，觀察系統，工作臺面等要無雜物，潔凈。防護鏡片需保持干凈。

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、冷卻檢查

2、 Cooling inspection

冷卻系統的維護，主要是定期檢查冷卻水質，若水質變差、混濁、透明度變差，應及時更換新水。定期檢查水箱內的存水量，若存水量不足應及時添加。本系統建議使用去離子水或純凈水。

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.

定期檢查各水管接口處是否有漏水，有漏水則擰緊該處螺絲不漏水。當氙燈和激光棒與腔體的封接處漏水時，主要原因是橡膠密封圈變形或老化，在擰緊螺絲后依然漏水，應仔細檢查橡膠圈，若已失效，則更換備用橡膠圈。

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、檢查激光焊接機光路組件

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

為了保證激光焊接機激光器一直處于正常的工作狀態，連續工作后或停止使用一段時間時，在開機前應對YAG棒、介質膜片及鏡頭保護玻璃等光路中的組件進行檢查，確定各光學組件沒有被污染、如有污染現象應及時進行處理，保證各光學組件不會在強激光照射下損壞。

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、檢查調整激光器諧振腔

4、 Check and adjust the laser resonator

設備操作人員可以經常用黑色像紙檢查激光器輸出光斑，一旦發現光斑不均勻或能量下降等現象，應及時對激光器的諧振腔進行調整，確保激光輸出的光束質量。調試操作人員必須具備激光防護的常識，工作中必須佩帶專用激光防護眼鏡。激光器的調整必須由經過專門培訓的人員進行，否則會因激光器失調或調偏造成光路上其它組件的損壞。

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.
