Kev vuam laser yog dab tsi? Kev piav qhia txog kev vuam laser! Txhua yam koj yuav tsum paub txog kev vuam laser, suav nrog cov ntsiab cai tseem ceeb thiab cov txheej txheem tseem ceeb!
Muaj ntau tus neeg siv khoom tsis nkag siab txog cov ntsiab cai ua haujlwm yooj yim ntawm lub tshuab laser vuam, tsis hais txog kev xaiv lub tshuab laser vuam zoo, txawm li cas los xij Mimowork Laser nyob ntawm no los pab koj txiav txim siab zoo thiab muab kev txhawb nqa ntxiv los pab koj nkag siab txog kev vuam laser.
Laser vuam yog dab tsi?
Laser vuam yog ib hom kev vuam melting, siv lub teeb laser ua qhov chaw cua sov vuam, lub hauv paus ntsiab lus vuam yog tias ib txoj kev tshwj xeeb los txhawb cov khoom nruab nrab, tsim cov oscillation resonant cavity, thiab tom qab ntawd hloov mus rau hauv lub teeb hluav taws xob stimulated, thaum lub teeb thiab daim ntawv ua haujlwm sib cuag, lub zog raug nqus los ntawm daim ntawv ua haujlwm, thaum qhov kub ncav cuag qhov chaw yaj ntawm cov khoom tuaj yeem vuam.
Raws li lub hauv paus ntsiab lus ntawm lub pas dej vuam, laser vuam muaj ob lub hauv paus vuam yooj yim: kev vuam cua sov thiab kev vuam tob tob (keyhole). Lub cua sov tsim los ntawm kev vuam cua sov yog diffused rau daim ntawv ua haujlwm los ntawm kev hloov pauv cua sov, yog li ntawd qhov chaw vuam yaj, tsis muaj vaporization tshwm sim, uas feem ntau siv rau hauv kev vuam ntawm cov khoom nyias nyias-ish ceev qis. Kev vuam sib xyaw ua ke tob ua rau cov khoom siv vaporizes thiab tsim cov plasma ntau. Vim yog cua sov siab, yuav muaj qhov nyob rau hauv pem hauv ntej ntawm lub pas dej molten. Kev vuam tob tob yog hom laser vuam siv dav tshaj plaws, nws tuaj yeem vuam daim ntawv ua haujlwm kom huv si, thiab lub zog nkag yog loj heev, ua rau kev vuam ceev ceev.
Cov Txheej Txheem Txheej Txheem hauv Laser Welding
Muaj ntau yam txheej txheem uas cuam tshuam rau qhov zoo ntawm laser vuam, xws li lub zog ceev, laser pulse waveform, defocusing, vuam ceev thiab kev xaiv ntawm cov roj shielding pab.
Laser Fais Fab Ceev
Lub zog ceev yog ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws hauv kev ua laser. Nrog lub zog ceev siab dua, txheej saum npoo tuaj yeem raug cua sov mus rau qhov kub npau npau hauv ib qho microsecond, ua rau muaj ntau qhov vaporization. Yog li ntawd, qhov ceev ceev siab yog qhov zoo rau cov txheej txheem tshem tawm cov khoom siv xws li drilling, txiav thiab engraving. Rau qhov ceev ceev qis, nws siv sijhawm ob peb milliseconds rau qhov kub ntawm qhov chaw kom ncav cuag qhov kub npau npau, thiab ua ntej qhov chaw vaporizes, hauv qab mus txog qhov kub yaj, uas yooj yim los tsim ib qho zoo melting weld. Yog li ntawd, nyob rau hauv daim ntawv ntawm cov cua sov conduction laser vuam, lub zog ceev ntau yog 104-106W / cm2.
Laser Pulse Waveform
Lub zog laser pulse waveform tsis yog tsuas yog ib qho tseem ceeb rau kev sib txawv ntawm cov khoom tshem tawm thiab cov khoom yaj, tab sis kuj yog ib qho tseem ceeb rau kev txiav txim siab qhov ntim thiab tus nqi ntawm cov khoom siv ua. Thaum lub teeb laser muaj zog siab raug tua rau ntawm qhov chaw ntawm cov khoom, qhov chaw ntawm cov khoom yuav muaj 60 ~ 90% ntawm lub zog laser cuam tshuam thiab suav tias poob, tshwj xeeb tshaj yog kub, nyiaj, tooj liab, txhuas, titanium thiab lwm yam khoom uas muaj kev cuam tshuam muaj zog thiab hloov pauv cua sov sai. Qhov kev cuam tshuam ntawm cov hlau hloov pauv nrog lub sijhawm thaum lub sijhawm laser pulse. Thaum qhov kub ntawm qhov chaw ntawm cov khoom nce mus rau qhov chaw yaj, qhov kev cuam tshuam txo qis sai, thiab thaum qhov chaw nyob hauv lub xeev yaj, qhov kev cuam tshuam ruaj khov ntawm qee tus nqi.
Laser Pulse Dav
Qhov dav ntawm lub pulse yog ib qho tseem ceeb ntawm kev vuam laser pulsed. Qhov dav ntawm lub pulse tau txiav txim siab los ntawm qhov tob ntawm kev nkag mus thiab thaj chaw cuam tshuam los ntawm cua sov. Qhov dav ntawm lub pulse ntev npaum li cas, qhov loj dua ntawm thaj chaw cuam tshuam los ntawm cua sov, thiab qhov tob ntawm kev nkag mus nce nrog 1/2 lub zog ntawm qhov dav ntawm lub pulse. Txawm li cas los xij, qhov nce ntawm qhov dav ntawm lub pulse yuav txo qhov muaj zog siab tshaj plaws, yog li qhov nce ntawm qhov dav ntawm lub pulse feem ntau yog siv rau kev vuam cua sov, ua rau qhov loj me ntawm qhov vuam dav thiab ntiav, tshwj xeeb tshaj yog tsim rau kev vuam ntawm cov phaj nyias thiab tuab. Txawm li cas los xij, qhov muaj zog siab tshaj plaws qis dua ua rau muaj cua sov ntau dhau, thiab txhua yam khoom muaj qhov dav ntawm lub pulse zoo tshaj plaws uas ua rau qhov tob ntawm kev nkag mus siab tshaj plaws.
Tshem Tawm Qhov Ntau
Feem ntau, kev vuam laser yuav tsum tau muaj qee qhov kev tsis pom tseeb, vim tias qhov ceev ntawm lub zog ntawm qhov chaw nruab nrab ntawm qhov tsom mus rau laser siab dhau, uas yooj yim ua rau cov khoom vuam ua rau hauv qhov. Qhov faib ntawm lub zog ceev yog sib npaug zos hauv txhua lub dav hlau ntawm qhov tsom mus rau laser.
Muaj ob hom kev defocus:
Qhov tsis pom kev zoo thiab qhov tsis pom kev zoo. Yog tias lub dav hlau focal nyob saum toj ntawm qhov workpiece, nws yog qhov tsis pom kev zoo; txwv tsis pub, nws yog qhov tsis pom kev zoo. Raws li geometric optics theory, thaum qhov deb ntawm qhov zoo thiab qhov tsis pom kev zoo thiab lub dav hlau vuam sib npaug, lub zog ceev ntawm lub dav hlau sib xws yog kwv yees li tib yam, tab sis qhov tseeb, cov duab pas dej ua los ntawm cov hlau yaj tau txais yog txawv. Hauv qhov xwm txheej ntawm qhov tsis pom kev zoo, kev nkag mus ntau dua tuaj yeem tau txais, uas yog cuam tshuam nrog cov txheej txheem tsim ntawm pas dej ua los ntawm cov hlau yaj.
Kev Ceev Vuam
Qhov ceev ntawm kev vuam txiav txim siab qhov zoo ntawm qhov chaw vuam, qhov tob ntawm kev nkag mus, thaj chaw cuam tshuam los ntawm cua sov thiab lwm yam. Qhov ceev ntawm kev vuam yuav cuam tshuam rau qhov cua sov nkag mus rau hauv ib lub sijhawm. Yog tias qhov ceev ntawm kev vuam qeeb dhau, qhov cua sov nkag mus siab dhau, ua rau cov khoom ua haujlwm kub hnyiab. Yog tias qhov ceev ntawm kev vuam ceev dhau, qhov cua sov nkag mus tsawg dhau, ua rau cov khoom ua haujlwm vuam ib nrab thiab tsis tiav. Kev txo qhov ceev ntawm kev vuam feem ntau yog siv los txhim kho qhov nkag mus.
Cov Pa Roj Tiv Thaiv Kev Pabcuam
Cov roj tiv thaiv cua tshuab yog ib qho txheej txheem tseem ceeb hauv kev siv laser vuam fais fab siab. Ntawm ib sab tes, los tiv thaiv cov khoom siv hlau los ntawm kev tawg thiab ua rau lub iav tsom iav puas tsuaj; Ntawm qhov tod tes, nws yog los tiv thaiv cov plasma tsim tawm hauv cov txheej txheem vuam los ntawm kev tsom ntau dhau thiab tiv thaiv lub laser los ntawm kev ncav cuag qhov chaw ntawm cov khoom. Hauv cov txheej txheem ntawm laser vuam, helium, argon, nitrogen thiab lwm yam roj feem ntau siv los tiv thaiv lub pas dej molten, yog li tiv thaiv cov khoom ua haujlwm los ntawm oxidation hauv kev tsim kho vuam. Cov yam ntxwv xws li hom roj tiv thaiv, qhov loj ntawm cov cua ntws thiab lub kaum sab xis tshuab muaj feem cuam tshuam loj heev rau cov txiaj ntsig vuam, thiab cov txheej txheem tshuab sib txawv kuj yuav muaj qee qhov cuam tshuam rau qhov zoo ntawm vuam.
