激ji光guang焊han接jie設she備bei中zhong的de激ji光guang焊han接jie技ji術shu已yi經jing成cheng為wei這zhe幾ji年nian快kuai速su增zeng長chang的de一yi項xiang技ji術shu
，也ye是shi很hen多duo人ren都dou很hen看kan好hao的de一yi項xiang加jia工gong技ji術shu。根gen據ju焊han縫feng的de方fang法fa可ke以yi分fen成cheng不bu同tong的de兩liang種zhong類lei型xing

，一般的激光功率密度非常小。第二種焊接的熱量非常小，而且焊合的時間也比較短，麵積也小，因此可以適用於比較小型的精密設備的焊接。

、激光焊接的特點

激ji光guang焊han接jie設she備bei傳chuan輸shu的de熱re量liang會hui比bi較jiao小xiao，但dan是shi焊han縫feng的de深shen度du和he寬kuan度du都dou比bi較jiao大da，因yin此ci性xing價jia比bi高gao。熱re量liang的de影ying響xiang比bi較jiao小xiao所suo以yi可ke以yi讓rang工gong件jian收shou縮suo或huo者zhe可ke以yi達da到dao少shao量liang的de變bian形xing
，所suo以yi可ke以yi不bu用yong焊han合he後hou再zai進jin行xing矯jiao形xing。另ling外wai焊han縫feng的de強qiang度du和he速su度du都dou比bi較jiao優you質zhi
，而er且qie能neng夠gou讓rang表biao麵mian的de狀zhuang態tai變bian得de更geng好hao，就jiu可ke以yi免mian掉diao焊han合he後hou的de清qing理li了le。一yi般ban情qing況kuang下xia，焊han接jie都dou有you它ta的de一yi致zhi性xing，穩wen定ding性xing也ye比bi較jiao高gao
，可ke以yi不bu添tian加jia什shen麼me金jin屬shu或huo者zhe焊han劑ji，還hai能neng夠gou讓rang部bu分fen的de異yi種zhong材cai料liao進jin行xing焊han接jie。
