Ntxiv mus, rau lub plhaub nrog cov phab ntsa sib txawv ntawm 0.4, 0.6, thiab 0.8mm, tsuas yog los ntawm kev kho cov laser tso zis hom, kev vuam zoo tuaj yeem ua tau. Txawm li cas los xij, rau ob-wavelength laser hybrid vuam kev daws teeb meem, nws yog ib qho tsim nyog yuav tsum tau hloov kho qhov muag teeb ntawm lub vuam taub hau lossis laser, uas yuav ua rau cov khoom siv ntau dua thiab cov nqi debugging lub sij hawm.
Yog li ntawd, qhov point-ring qhov chawlaser vuamKev daws tsis tuaj yeem tsuas yog ua tiav ultra-high-speed sab saum toj npog vuam ntawm 300mm / s thiab txhim kho kev tsim khoom ntawm cov roj teeb hluav taws xob. Rau cov tuam txhab tsim cov roj teeb uas xav tau kev hloov pauv ntau zaus, cov tshuaj no tuaj yeem txhim kho cov khoom siv thiab cov khoom zoo. compatibility, shortening tus qauv hloov thiab debugging lub sij hawm.
Qhov tshwm sim ntawm lub roj teeb sab saum toj npog vuam nrog phab ntsa thickness 0.4mm (welding ceev 300mm / s)
Qhov tshwm sim ntawm lub roj teeb sab saum toj npog vuam nrog phab ntsa thickness 0.6mm (welding ceev 300mm / s)
Corona Laser Weld Penetration rau Thin-Wall Cell Vuam - txheej txheem muaj peev xwm
Ntxiv rau Corona laser tau hais los saum no, AMB lasers thiab ARM lasers muaj cov yam ntxwv zoo sib xws ntawm cov khoom siv kho qhov muag thiab tuaj yeem siv los daws cov teeb meem xws li kev txhim kho laser weld spatter, txhim kho weld nto zoo, thiab txhim kho kev kub ceev vuam stability.
4. Cov ntsiab lus
Cov kev daws teeb meem ntau yam tau hais los saum no yog txhua yam siv hauv kev tsim khoom tiag tiag los ntawm cov tuam txhab lag luam lithium roj teeb hauv tsev thiab txawv teb chaws. Vim lub sij hawm ntau lawm thiab cov txheej txheem sib txawv, cov txheej txheem sib txawv tau siv dav hauv kev lag luam, tab sis cov tuam txhab muaj kev xav tau ntau dua rau kev ua haujlwm zoo thiab zoo. Nws tab tom txhim kho tas li, thiab ntau cov thev naus laus zis tshiab yuav sai sai no tau siv los ntawm cov tuam txhab ua ntej ntawm thev naus laus zis.
Tuam Tshoj txoj kev lag luam roj teeb hluav taws xob tshiab tau pib qeeb thiab tau tsim sai sai los ntawm lub teb chaws txoj cai. Lwm yam thev naus laus zis tau txuas ntxiv mus ntxiv nrog kev sib koom tes ntawm tag nrho cov kev lag luam saw, thiab tau ua tiav qhov sib txawv nrog cov tuam txhab thoob ntiaj teb zoo. Raws li cov chaw tsim khoom siv roj teeb lithium hauv tsev, Maven tseem niaj hnub tshawb nrhiav nws tus kheej thaj chaw kom zoo dua, pab txhim kho cov khoom siv roj teeb, thiab muab cov kev daws teeb meem zoo dua rau kev tsim cov khoom siv hluav taws xob tshiab lub zog cia roj teeb module packs.
