Raws li ib qho ntawm cov tub ntxhais tseem ceeb ntawm kev lag luam niaj hnub, daim ntawv thov ntawm laser kev lag luam tau nkag mus rau hauv cov tsheb, aerospace, thiab lub zog tshiab. Raws li ob lub ntsiab kev ua tshuab ua ke, fiber ntau laser txiav thiab lawv cov txiaj ntsig kev tsim ua ke ntawm kev ua haujlwm zoo, qhov ntsuas kub, thiab tsis tshua muaj cua sov cuam tshuam. Txawm li cas los xij, qhov tseem ceeb sib txawv ntawm ob lub tshuab thev naus laus zis tsis tsuas yog xav hauv kev ua cov hom phiaj thiab txheej txheem tsis txheeb, tab sis kuj cuam tshuam rau tusKev tiv thaiv kev nyab xeeblub tswv yim hauv qhov chaw tsim khoom.Acrylic Kev Tiv Thaiv Kev Tiv Thaiv Laser(Ua los ntawm polymethyl methacrylate) tau dhau los ua qhov kev xaiv tseem ceeb rau cov khoom siv roj av laser vim nws qhov kev kho qhov muag thiab ua cov yam ntxwv.
Kev sib txawv ntawm cov fiber ntau laser txiav thiab vuam
1. Lub Zog Tub Ntxhais
Lub ntsiab lus ntawm fiber ntau laser txiav yog kom tau agrorize nqaj nrog ultra-siab fais fab density (1}}}}} {) los ua ib qho kev txwv. Piv txwv li, thaum txiav stainless hlau, lub laser tsom xav kom muaj kev tswj hwm los ntawm cov roj ntsha (oxygen lossis nitrogen) kom ntseeg tau tias kev phais mob du thiab Burr-dawb. Fiber laser welding achieves material fusion at a medium power density (10⁵-10⁶ W/cm²) and completes the connection through heat conduction or keyhole effect. Noj cov vuam ntawm cov roj teeb hluav taws xob tab yog qhov piv txwv, lub sijhawm laser yuav tsum tau nruj me ntsis cov tswv yim ua rau muaj cov khoom siv hluav taws xob ntau ntawm cov khoom siv hluav taws xob.
2. Txheej Txheem Kev Sib Piv
Cov roj-pab sib txawv: txiav cov kev tso siab rau cov tshuaj siab siab (oxygen accelerase, nitrogen inhibation oxidation) kom tshem tawm cov khoom siv molten; Vuam siv inert roj (xws li argon) los npog lub pas dej Molten kom tiv thaiv cov hlau oxidation thiab huab cua.
Beam hom xaiv: Kev txiav feem ntau siv kho qhov hluav taws xob ntawm cov khoom siv tuab (xws li siv cov khoom siv tuab)
Thermal kev tswj hwm yuav tsum: vuam yuav tsum tau tswj hwm kom tsis txhob muaj kev tiv thaiv tshav kub. Piv txwv li, kev sib khi vuam ntawm cov roj teeb hluav taws xob tshiab yuav tsum muaj qhov dav ntawm qhov kub-{1}}. 3 hli; Kev txiav tawm yuav tsum tau nrawm kub dissipation kom tiv thaiv cov soliary solidification ntawm kev txiav seam.
3. Kev Nyab Xeeb Kev Nyab Xeeb
Txiav kev pheej hmoo: ya hlau cov lus (nrawm tuaj yeem ncav cuag 50m / s), qhov loj me dua li 10μm) thiab ultraviolet hluav taws xob yog qhov muaj kev phom sij. Piv txwv li, cov hlau oxide plua plav tsim thaum txiav cov hlau hlau yog cov nplaim taws thiab xav tau yuav tau nruab nrog tawg kom huv cov plua plav.
Vuam kev pheej hmoo: muaj zog xav txog lub teeb (lub zog refendity tuaj yeem ncav cuag cov khoom lag luam 90%), tooj liab) yuav tsum tsom rau. Txoj kev vuam yuav ua rau cov neeg hlau Vapor tawg vim yog qhov sib npaug ntawm qhov sib tsoo, ua rau muaj kev phom sij thib ob.
Daim Ntawv Thov Kev Ua Haujlwm thiab xaivAcrylic Kev Tiv Thaiv Kev Tiv Thaiv Laser
1. Cov ntsiab lus zoo
Kev ua kom zoo nkauj: Pom lub teeb pom kev hloov pauv tuaj yeem ncav cuag 92%, thaum thaiv 1064nm fiber ntau laser kom muaj kev ua haujlwm meej ntawm kev pom.
Kev Tsim Khaub Ncaws Hnav: Lub ntom ntom tsuas yog 1/2 ntawm iav, haum rauTxawb tiv thaiv mobile lossis tuav tes ntaus ntawv saib lub Windows.
Kev ua cov txheej txheem: Txhawb kev ua xws li kub nyhiab thiab tho, thiab tuaj yeem hloov kho cov cuab yeej tshwj xeeb.
2. Cov ntaub ntawv raug cai
Qhib cov khoom siv laser: raws li kev soj ntsuam cov khoom siv Laser ntawm txiav cov tshuab thiab tshuab vuam, nws ua tau raws li EN 60825 chav kawm 1 tus qauv kev nyab xeeb.
Kev ua kom muaj kev tiv thaiv cov khoom lag luam: hauv kev ua cov hlau xws li txhuas thiab tooj liab, nws tiv thaiv teeb pom kev ua rau cov neeg ua haujlwm puas.
