5、熱處理和激光熔覆設備的用戶進行調查，很多用戶反映設備性能較差，大部分情況為：設備穩定性很差，年故障次數5次以上；激光器使用一至兩年后出現功率輸出變小、模式變差，因此造成大部分成套設備經常處于低性能狀態，甚至停運。主要問題集中在激光器的關鍵技術指標達不到標準。2.

7、, or eve n outages. Laser focus on key issues in the key in dicators-sta ndard tech no logy.千瓦級大功率 CO2激光器存在的主要問題及描述序號主要問題簡單描述激光器無法在額定功率下穩定運行，最高功率只能在額定功率的60%下運行（如5000W橫流CO2激光器可以穩定運行的功率激光功率“大打折扣”，影響加工效率僅為3000V）也有顯示的功率數偏高的現象；如5000W橫流CO2激光器功率計顯示輸出功率為5000W按計量局標準的手持功率檢測儀器顯示僅為 3000W因此，很多高功率設備處于低功率運行狀態，加工效率

8、降約為標準的一半。根據行業技術標準的規范，合格的橫流CO2激光器可以獲得 多模和低階模兩種激光束模式，低階模狀態的功率為多模的1/2。低階模狀態性能目前國內的大部分橫流 C02激光器通過加“光柵”取得低階 差，無法開展新業2模狀態，只能獲得多模功率的1/3左右；按照上面多模激光輸出務（激光焊接、激功率情況，以5000W的橫流C02激光器為例，在低階模穩定運行 光切割）狀態下，只獲得1000W左右（按技術標準可獲得低階模2500W。因此，大部分已投入生產的橫流 C02激光器的僅采用多模光束，幾乎沒有開發低階模及環形模的激光焊接應用技術。設備運行過程中，經常出現光路偏差、電路故障等問題，影 響生產

9、進度。激光器穩定性差經過調查分析，激光器的諧振腔穩定性差， 容易出現光軸漂序號主要問題簡單描述電路板控制，穩定性差；放電系統產生的增益區小。對于復雜的熔覆工藝，大部分激光設備客戶采用重力送粉機4工藝裝備差構，進行鋪粉或預置粉末的辦法；無法對復雜形狀的零部件進行三維送粉和修復。1kw-class high-power CO2 laser and the main problems describedMain issues No.BriefLasers can not be rated power un der the stablepowerCO2operati onof power only i
