5、熱處理和激光熔覆設(shè)備的用戶進(jìn)行調(diào)查，很多用戶反映設(shè)備性能較差，大部分情況為：設(shè)備穩(wěn)定性很差，年故障次數(shù)5次以上；激光器使用一至兩年后出現(xiàn)功率輸出變小、模式變差，因此造成大部分成套設(shè)備經(jīng)常處于低性能狀態(tài)，甚至停運(yùn)。主要問(wèn)題集中在激光器的關(guān)鍵技術(shù)指標(biāo)達(dá)不到標(biāo)準(zhǔn)。2.

8、降約為標(biāo)準(zhǔn)的一半。根據(jù)行業(yè)技術(shù)標(biāo)準(zhǔn)的規(guī)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(tài)的功率為多模的1/2。低階模狀態(tài)性能目前國(guó)內(nèi)的大部分橫流 C02激光器通過(guò)加“光柵”取得低階 差，無(wú)法開(kāi)展新業(yè)2模狀態(tài)，只能獲得多模功率的1/3左右；按照上面多模激光輸出務(wù)（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(wěn)定運(yùn)行 光切割）狀態(tài)下，只獲得1000W左右（按技術(shù)標(biāo)準(zhǔn)可獲得低階模2500W。因此，大部分已投入生產(chǎn)的橫流 C02激光器的僅采用多模光束，幾乎沒(méi)有開(kāi)發(fā)低階模及環(huán)形模的激光焊接應(yīng)用技術(shù)。設(shè)備運(yùn)行過(guò)程中，經(jīng)常出現(xiàn)光路偏差、電路故障等問(wèn)題，影 響生產(chǎn)

9、進(jìn)度。激光器穩(wěn)定性差經(jīng)過(guò)調(diào)查分析，激光器的諧振腔穩(wěn)定性差， 容易出現(xiàn)光軸漂序號(hào)主要問(wèn)題簡(jiǎn)單描述電路板控制，穩(wěn)定性差；放電系統(tǒng)產(chǎn)生的增益區(qū)小。對(duì)于復(fù)雜的熔覆工藝，大部分激光設(shè)備客戶采用重力送粉機(jī)4工藝裝備差構(gòu)，進(jìn)行鋪粉或預(yù)置粉末的辦法；無(wú)法對(duì)復(fù)雜形狀的零部件進(jìn)行三維送粉和修復(fù)。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
