Laser vuam yuav tau paub los ntawm kev nruam lossis pulsed laser Generator. Lub hauv paus ntsiab lus ntawm Laser Vuam yuav tuaj yeem faib ua tshav kub conduction vuam thiab laser sib sib zog nqus dej. Fais fab ceev tsawg dua 104 ~ 105 w / cm2 yog cua sov conduction vuam, nyob rau lub sij hawm no, qhov tob ntawm luting, thiab vuam ceev qeeb; Thaum lub hwj chim ceev yog ntau dua 105 ~ 107 w / cm2, ua kom muaj kev sib cav sib ceg, uas muaj cov yam ntxwv sib sib zog nqus vuam, uas muaj cov yam ntxwv sib sib zog nqus vuam, uas muaj qhov tob tob vuam thiab qhov tob loj-dav sib npaug.
Niaj hnub no, peb yuav piav qhia txog kev paub ntawm cov xwm txheej loj uas cuam tshuam qhov zoo ntawm laser sib sib zog nqus dej fusion vuam
1. Laser Fais Fab
Hauv laser sib sib zog nqus dej fusion vuam, laser zog tswj ob lub qhov tob tob thiab vuam ceev. Weld qhov tob yog ncaj qha ntsig txog lub nqaj hluav taws xob ceev ceev thiab yog txoj haujlwm ntawm cov teeb meem nqaj lub zog thiab cov nqaj focal. Feem ntau hais lus, rau qee txoj kab ib nrab ntawm nqaj, kev nkag mus tob ntxiv nrog qhov nce ntawm nqaj fais fab.
2. Focal chaw
Beam qhov loj me me yog ib qho tseem ceeb tshaj plaws cov hloov pauv hauv laser vuam vim tias nws txiav txim lub hwj chim ntom ntom. Tab sis ntsuas nws yog qhov kev sib tw rau high-hwj chim lasers, txawm hais tias muaj ntau txoj kev ntsuas tsis ncaj qha muaj.
Lub diffraction txwv qhov chaw loj ntawm cov nqaj tsom tau suav raws li qhov loj me dua li suav tus nqi vim tias muaj cov laj thawj tsis zoo. Qhov yooj yim ntsuas kev ntsuas yog qhov ISO-kub profile txoj kev, uas ntsuas txoj haujlwm ntawm lub cheeb tsam tuab yog hlawv thiab loj los ntawm polypropylene phaj. Cov qauv no los ntawm kev ntsuas kev ntsuas, Masters The Laser hluav taws xob loj thiab Beam nkaus Time.
3. Cov roj tiv thaiv
Cov txheej txheem laser vuam feem ntau siv cov roj tiv thaiv tiv thaiv (helium, nitrogen) los tiv thaiv cov pas dej Molon, tiv thaiv kev ua haujlwm los ntawm oxidation hauv cov txheej txheem vuam. Qhov laj thawj thib ob rau kev siv roj tiv thaiv yog tiv thaiv lub lens los ntawm kev sib kis los ntawm cov kua hlau thiab sputtering los ntawm kua dej ntws. Tshwj xeeb tshaj yog nyob rau hauv high-fais laser vuam, lub ejecta ua tau haib heev, nws yog ib qho tsim nyog los tiv thaiv lub lens. Qhov thib peb cov nyhuv ntawm cov roj tiv thaiv yog tias nws yog qhov ua tau zoo rau cov kev thaiv ntshav ntshav plasma tsim los ntawm high-pel-wel-hwj chim Laser Vuam. Cov hlau vapor nqus cov nqaj laser thiab ionizes rau hauv cov huab plasma huab. Cov roj tiv thaiv ib puag ncig ntawm cov hlau vapor kuj ionizes vim muaj cua sov. Yog tias muaj ntshav ntau dhau, cov nqaj laser yog xyov noj los ntawm ntshav ntshav. Raws li lub zog thib ob, ntshav tshwm sim ntawm qhov chaw ua haujlwm, uas ua rau Weld Cast thiab Weld pas nto nto dav.
Yuav xaiv cov pa tiv thaiv kom zoo?
4. Kev nqus tau tus nqi
Lub laser nqus ntawm cov khoom nyob ntawm qee cov khoom tseem ceeb ntawm cov khoom, refendity, thermal conductivity, kub kub, thiab evaporation kub. Ntawm txhua yam ntawm cov xwm txheej, qhov tseem ceeb tshaj plaws yog qhov nqus tau tus nqi.
Ob yam cuam tshuam rau kev nqus cov khoom nqus ntawm cov khoom siv laser nqaj. Qhov thib ib yog cov kev tiv thaiv coefficient ntawm cov khoom. Nws yog pom tias qhov nqus tau ntawm cov khoom siv yog proportional rau cov cag kas ntawm cov coefficient, thiab cov coefficients sib txawv nrog kub. Thib ob, lub xeev saum npoo (lossis ua tiav) ntawm cov khoom muaj ib qho tseem ceeb ntawm kev nqus cov nqaj, uas muaj cov nyhuv tseem ceeb ntawm kev siv vuam.
5. Vuam Ceev
Lub vuam ceev muaj qhov cuam tshuam zoo ntawm qhov tob ntawm kev nkag mus. Ua kom lub nrawm nrawm yuav ua rau qhov tob ntawm kev nkag mus rau qhov muag, tab sis qis dhau yuav ua rau muaj cov ntaub ntawv meting ntau thiab ua haujlwm vuam. Yog li ntawd, muaj qhov kev siv hluav taws xob tsim nyog rau cov khoom siv nrog cov khoom siv laser thiab qhov tob tshaj plaws yuav tau txais ntawm tus nqi ceev.
6. Focal Ntev ntawm lub lens tsom
Lub ntsiab lus tseem ceeb yog feem ntau ntsia hauv lub taub hau ntawm rab phom wel, feem ntau, lub 632 ~ 254] focal ntev tau xaiv. Kev tsom mus rau qhov loj me yog sib npaug rau lub focal ntev, tus luv luv lub focal ntev, qhov me me. Txawm li cas los xij, qhov ntev ntawm focal ntev kuj cuam tshuam rau qhov tob ntawm kev ua kom pom tseeb, tab sis vim hais tias qhov tob ntawm kev ua kom pom tseeb yog me me, qhov deb Nruab nrab ntawm lub lens thiab cov haujlwm ua haujlwm yuav tsum raug tswj xyuas kom raug, thiab qhov tob ntawm kev nkag mus yog tsis loj. Vim tias muaj kev sib txig sib luag lossis tus weld yuav tsum tau nce ntxiv los ntawm nce qhov chaw loj. Hauv qhov no, ib qho siab dua laser tso tawm hluav taws xob (hluav taws xob ceev) yuav tsum ua tiav qhov sib zog tob tob lub qhov kev cuam tshuam.
