140DAI44000 1、激光焊接原理——激光是輻射的受激發(fā)射光放大的簡(jiǎn)稱(chēng)，由于其獨(dú)有的高亮度、高方向性、高單色性、高相干性，自誕生以來(lái)，其在工業(yè)加工中的應(yīng)用十分廣泛，成為未來(lái)制造系統(tǒng)共同的加工手段。用激光焊接加工是利用高輻射強(qiáng)度的激光束，激光束經(jīng)過(guò)光學(xué)系統(tǒng)聚焦后，其激光焦點(diǎn)的功率密度為104~107W/cm2，加工工件置于激光焦點(diǎn)附近進(jìn)行加熱熔化，熔化現(xiàn)象能否產(chǎn)生和產(chǎn)生的強(qiáng)弱程度主要取決于激光作用材料表面的時(shí)間、功率密度和峰值功率。控制上述各參數(shù)就可利用激光進(jìn)行各種不同的焊接加工。
2、激光焊接的一般特點(diǎn)——激光焊接是利用激光束作為熱源的一種熱加工工藝，它與電子束等離子束和一般機(jī)械加工相比較，具有許多優(yōu)點(diǎn)：（1）激光束的激光焦點(diǎn)光斑小，功率密度高，能焊接一些高熔點(diǎn)、高強(qiáng)度的合金材料；（2）激光焊接是無(wú)接觸加工，沒(méi)有工具損耗和工具調(diào)換等問(wèn)題。激光束能量可調(diào)，移動(dòng)速度可調(diào)，可以多種焊接加工；（3）激光焊接自動(dòng)化程度高，可以用計(jì)算機(jī)進(jìn)行控制，焊接速度快，功效高，可方便的進(jìn)行任何復(fù)雜形狀的焊接；（4）激光焊接熱影響區(qū)小，材料變形小，無(wú)需后續(xù)工序處理；（5）激光可通過(guò)玻璃焊接處于真空容器內(nèi)的工件及處于復(fù)雜結(jié)構(gòu)內(nèi)部位置的工件；（6）激光束易于導(dǎo)向、聚焦，實(shí)現(xiàn)各方向變換；（7）激光焊接與電子束加工相比較，不需要嚴(yán)格的真空設(shè)備系統(tǒng)，操作方便；（8）激光焊接生產(chǎn)效率高，加工質(zhì)量穩(wěn)定可靠，經(jīng)濟(jì)效益和社會(huì)效益好。
