Vuam yog txheej txheem ntawm kev koom nrog ob lossis ntau dua hlau ua ke los ntawm kev siv cov cua sov. Vuam feem ntau suav nrog cov khoom siv cua sov rau nws cov ntsiab lus melting kom cov hlau hauv paus melts los ua cov khoob ntawm cov pob qij txha, ua kom muaj kev sib txuas zoo. Laser welding yog ib txoj kev sib txuas uas siv laser ua qhov cua sov.
Siv lub square case fais fab roj teeb ua piv txwv: lub roj teeb tub ntxhais txuas nrog laser los ntawm ntau qhov chaw. Thaum lub sij hawm tag nrho cov txheej txheem laser welding, cov khoom sib txuas lub zog, kev ua haujlwm ntau lawm, thiab tus nqi tsis zoo yog peb qhov teeb meem uas kev lag luam muaj kev txhawj xeeb ntau dua. Cov khoom siv sib txuas lub zog tuaj yeem cuam tshuam los ntawm metallographic nkag mus tob thiab dav (zoo cuam tshuam nrog lub teeb ci laser); ntau lawm efficiency yog feem ntau muaj feem xyuam rau kev muaj peev xwm ntawm lub laser lub teeb qhov chaw; qhov tsis xws luag yog feem ntau cuam tshuam nrog kev xaiv ntawm lub teeb laser; yog li ntawd, tsab xov xwm no tham txog cov uas muaj nyob rau hauv kev ua lag luam. Kev sib piv yooj yim ntawm ntau qhov chaw teeb pom kev laser tau ua, vam tias yuav pab cov neeg ua haujlwm sib koom ua ke.
Vimlaser vuamyog qhov tseem ceeb ib txheej txheem hloov dua siab tshiab, ob peb tus yuam sij divourity, lub zog sib faib, kev ua kom haum rau cov khoom siv welding, ua cov ntaub ntawv sib txawv thiab cov khoom siv Feem ntau yog siv los txheeb xyuas thiab sib piv cov teeb pom kev laser los ntawm cov lus qhia no.
Singlemode-Multimode Laser Sib Piv
Ib hom multi-mode txhais:
Ib hom yog hais txog ib qho qauv kev faib tawm ntawm lub zog laser ntawm lub dav hlau ob sab, thaum ntau hom yog hais txog lub zog spatial faib qauv tsim los ntawm superposition ntawm ntau yam kev faib tawm. Feem ntau, qhov loj ntawm lub teeb pom kev zoo M2 tuaj yeem siv los txiav txim seb lub fiber ntau laser tso zis yog ib hom lossis ntau hom: M2 tsawg dua 1.3 yog ib hom laser ntshiab, M2 ntawm 1.3 thiab 2.0 yog ib qho quasi- ib hom laser (ob peb hom), thiab M2 ntau dua 2.0. Rau multimode lasers.

Raws li pom nyob rau hauv daim duab: Daim duab b qhia lub zog faib ntawm ib qho tseem ceeb hom, thiab lub zog faib nyob rau hauv ib qho kev taw qhia dhau los ntawm qhov chaw ntawm lub voj voog yog nyob rau hauv daim ntawv ntawm ib tug Gaussian nkhaus. Daim duab qhia tau hais tias muaj ntau hom kev faib hluav taws xob, uas yog lub zog spatial faib tsim los ntawm superposition ntawm ntau hom laser. Qhov tshwm sim ntawm multi-mode superposition yog lub tiaj-saum nkhaus.
Hom ib hom lasers: IPG YLR-2000-SM, SM yog cov ntawv luv ntawm Ib Hom. Cov kev suav siv collimated tsom xam 150-250 los xam qhov tsom qhov chaw loj, lub zog ceev yog 2000W, thiab lub zog tsom xam qhov ceev yog siv rau kev sib piv.
Kev sib piv ntawm ib hom thiab ntau homlaser vuamteebmeem
Ib hom laser: me me txoj kab uas hla, siab zog ceev, muaj peev xwm nkag mus tau zoo, me me tshav kub-tshem tawm tsam, zoo ib yam li riam ntse, tshwj xeeb tshaj yog haum rau vuam nyias daim hlau thiab high-speed vuam, thiab yuav siv tau nrog galvanometers rau txheej txheem me me. qhov chaw thiab cov khoom muaj kev cuam tshuam ntau heev (tseem ceeb heev) pob ntseg, cov khoom sib txuas, thiab lwm yam), raws li qhia hauv daim duab saum toj no, ib hom muaj lub qhov me me thiab qhov txwv ntim ntawm cov hlau tsis muaj zog, yog li nws feem ntau tsis muaj teeb meem xws li internal pores. Ntawm qhov nrawm qis, qhov tsos yog ntxhib yam tsis muaj cua tiv thaiv. Thaum muaj kev kub ceev, kev tiv thaiv yog ntxiv. Cov roj ua haujlwm zoo yog qhov zoo, qhov ua tau zoo yog siab, cov welds yog du thiab tiaj tus, thiab tus nqi tawm los yog siab. Nws yog tsim rau pawg welding thiab nkag welding.
Multi-mode laser: Cov tub ntxhais txoj kab uas hla loj, me ntsis qis zog dua li ib hom laser, blunt riam, loj keyhole, thicker hlau qauv, me me qhov tob-rau-dav piv, thiab tib lub zog, qhov tob tob yog 30% qis dua. dua li ntawm ib hom laser, yog li nws tsim nyog rau kev siv Tsim nyog rau lub pob tw weld ua thiab tuab phaj ua nrog loj sib dhos sib txawv.
Composite-Nplhaib Laser Contrast
Hybrid vuam: Lub semiconductor laser beam nrog lub wavelength ntawm 915nm thiab fiber ntau laser beam nrog ib tug wavelength ntawm 1070nm yog ua ke nyob rau hauv tib lub taub hau vuam. Ob lub laser beams yog coaxially faib thiab focal dav hlau ntawm ob lub laser beam tuaj yeem hloov kho tau yooj yim, kom cov khoom muaj ob qho tib si semiconductorlaser vuammuaj peev xwm tom qab vuam. Cov nyhuv yog ci thiab muaj qhov tob ntawm fiber ntaulaser vuam.
Semiconductors feem ntau siv lub teeb pom kev loj ntawm ntau tshaj 400um, uas yog lub luag haujlwm tseem ceeb rau preheating cov khoom, melting saum npoo ntawm cov khoom, thiab ua rau cov khoom nqus tau ntawm fiber ntau laser (cov khoom siv qhov nqus ntawm laser nce raws li qhov kub thiab txias)
Nplhaib laser: Ob lub fiber ntau laser modules emit laser teeb, uas yog kis mus rau cov khoom nto los ntawm ib tug composite optical fiber (ntiv nplhaib optical fiber nyob rau hauv cylindrical optical fiber).
Ob lub laser beams nrog annular qhov chaw: lub nplhaib sab nrauv yog lub luag haujlwm rau kev nthuav dav qhov qhib qhov qhib thiab yaj cov khoom, thiab lub nplhaib puab lub laser yog lub luag haujlwm rau qhov tob tob, ua rau ultra-low spatter vuam. Lub nplhaib sab hauv thiab sab nraud laser fais fab core diameters tuaj yeem sib tw dawb, thiab cov tub ntxhais txoj kab uas hla tuaj yeem sib tw dawb. Lub qhov rais txheej txheem yog hloov tau ntau dua li ntawm ib lub teeb laser.
Kev sib piv ntawm kev sib xyaw-vuam vuam cuam tshuam
Txij li thaum hybrid welding yog ib qho kev sib xyaw ntawm semiconductor thermal conductivity vuam thiab fiber ntau optic sib sib zog nqus nqus vuam, lub nplhaib sab nrauv nkag yog ntiav, cov qauv metallographic yog sharper thiab slender; Nyob rau tib lub sijhawm, qhov zoo li yog thermal conductivity, lub pas dej molten muaj qhov hloov pauv me me, ntau qhov loj, thiab lub pas dej molten yog qhov ruaj khov dua, muaj kev cuam tshuam rau lub ntsej muag smoother.
Txij li thaum lub nplhaib laser yog kev sib xyaw ua ke ntawm kev sib sib zog nqus vuam thiab sib sib zog nqus nqus vuam, lub nplhaib sab nraud tuaj yeem tsim qhov tob tob, uas tuaj yeem nthuav dav qhov qhib qhov tseem ceeb. Tib lub zog muaj ntau dua qhov tob tob thiab cov metallography thicker, tab sis tib lub sijhawm, kev ruaj ntseg ntawm lub pas dej molten yog me ntsis tsawg dua Qhov kev hloov pauv ntawm optical fiber semiconductor yog me ntsis loj dua li ntawm cov khoom sib txuas, thiab qhov roughness kuj loj.
