Kev vuam laseryog ib qho tseem ceeb ntawm kev siv cov txheej txheem ua cov khoom siv laser. Nws feem ntau yog siv rau kev vuam cov khoom siv nyias-phab ntsa thiab kev vuam qeeb qeeb. Cov txheej txheem vuam yog hom kev xa cua sov, uas yog, lub teeb laser ua rau qhov chaw ua haujlwm sov, thiab qhov kub ntawm qhov chaw sib kis mus rau sab hauv los ntawm kev xa cua sov. Los ntawm kev tswj cov kev txwv xws li qhov dav, lub zog, lub zog siab tshaj plaws thiab qhov rov ua dua ntawm lub laser pulse, lub workpiece yaj los ua ib lub pas dej molten tshwj xeeb. Siv dav dua hauv kev tsim khoom siv tshuab, aerospace, kev lag luam tsheb, hmoov metallurgy, biomedical microelectronics kev lag luam thiab lwm yam teb.
Nrog rau kev loj hlob sai ntawm cov tsheb fais fab tshiab, kev nthuav dav ntawm kev tsim cov roj teeb fais fab tau tsav kev loj hlob ntawm kev vuam laser. Txij li thaum ib nrab xyoo 2018, kev vuam laser tes tau maj mam nrov zuj zus, thiab tau dhau los ua qhov chaw ci ntsa iab hauv kev lag luam vuam laser hauv thawj ib nrab xyoo no. Nrog rau qib kev siv tshuab thiab cov xwm txheej siv tam sim no ntawmtes tuav laser vuam, nws yuav zoo li hloov lub tshuab vuam TIG ib txwm muaj (argon arc vuam) kev ua lag luam.
Nyob rau hauv xyoo tas los no,cov laser fiber ntautau ua tiav zoo heev, thiab lawv cov txiaj ntsig feem ntau suav nrog: tus nqi hloov pauv photoelectric siab, cua sov sai, yooj ywm zoo, muaj peev xwm tiv thaiv kev cuam tshuam zoo, tus nqi qis, lub neej ntev, tsis tas hloov kho, tsis tas saib xyuas, ruaj khov siab, me me, Cov khoom siv vuam laser tes tuav siv fiber lasers kuj tau maj mam tsim.
Kev vuam laserYuav tsum tau muaj kev sib dhos ua ke siab ntawm cov khoom ua haujlwm, thiab cov hlau vuam yooj yim ua rau muaj qhov tsis zoo. Txhawm rau daws qhov teeb meem no, tus tsim qauv xa mus rau cov khoom siv vuam laser ntawm lub dav hlau tshwj xeeb los tsim cov khoom siv vuam laser tes nrog qhov chaw viav vias. Lub laser yog nyob rau hauv daim ntawv ntawm "8" lossis "0" hom viav vias tuaj yeem txo qhov kev sib dhos ua ke ntawm cov khoom ua haujlwm thiab ua rau kom vuam nkag mus. Tom qab ntau qhov kev txhim kho thiab kev txhim kho, cov khoom siv vuam laser tes tam sim no muaj zog ntawm 0.5-1.5KW, thiab qhov loj me thiab qhov hnyav ntawm cov khoom siv yog sib npaug rau argon arc vuam tshuab, uas tuaj yeem vuam cov hlau phaj ntawm 3 hli lossis tsawg dua. Txhawm rau daws qhov tsis txaus ntawm lub zog vuam tsis txaus ntawm cov qauv vuam laser, nyob rau xyoo tas los no, cov tuam txhab tsim khoom siv tau koom ua ke cov khoom siv pub hlau tsis siv neeg raws li kev vuam laser, thiab tsim cov khoom siv vuam laser tes uas tuaj yeem pub hlau tsis siv neeg, uas feem ntau ua tau raws li qhov xav tau ntawm cov hlau nyias nyias hauv qab 4m. Qhov vuam tuaj yeem hloov thiab dhau argon arc vuam, paub txog kev kub ceev, qis cua sov nkag, me me deformation, tsis tshua muaj nqi tiv thaiv ib puag ncig vuam, thiab tus nqi tsim khoom qis dua li ntawm argon arc vuam nyob rau hauv tib qho xwm txheej.
Thaum ua haujlwm, lub taub hau tes tuav ntawm lub tshuab vuam muaj qhov dav scanning, thiab nws qhov chaw me me, yog li thaum vuam, nws scans los ntawm ib qho taw tes mus rau lwm qhov kab los ntawm kab, yog li tsim cov hlaws weld. Piv nrog rau lub tshuab vuam txias ib txwm muaj, qhov ceev vuam ntawm tes tuav laser vuam yuav sai dua, thiab cov txheej txheem vuam ib zaug txiav txim siab tias nws tsim nyog dua rau kev vuam loj ntawm cov seams ntev ncaj.
Thiab lub tshuab vuam laser tes tuav siv qhov chaw me me, thiab feem ntau muaj ntau lub taub hau tuav tes. Raws li qhov xav tau sib txawv ntawm cov khoom hlau xws li vuam sab nraud, vuam sab hauv, vuam sab xis, vuam ntug nqaim, thiab vuam qhov chaw loj, ntau lub taub hau vuam tes tuav tuaj yeem xaiv tau. Cov khoom uas tuaj yeem vuam tau ntau yam, thiab cov duab khoom yooj ywm dua. Rau cov chaw ua haujlwm tsim khoom koom nrog kev ua tiav me me thiab kev vuam tsis loj, cov tshuab vuam laser tes tuav yog qhov kev xaiv zoo tshaj plaws.
Cov ntaub ntawv hlau sib txawv muaj cov ntsiab lus yaj sib txawv: qhov kev teeb tsa ntawm cov txheej txheem vuam rau ntau hom ntaub ntawv vuam yog qhov nyuaj heev, thiab cov khoom thermophysical ntawm cov ntaub ntawv vuam yuav qhia txog qhov sib txawv nrog kev hloov pauv kub; tus nqi nqus ntawm ntau hom ntaub ntawv rau laser kuj tseem yuav sib txawv nrog Kev hloov pauv kub qhia txog qhov sib txawv; qhov sib koom ua ke yaj thiab kev hloov pauv ntawm thaj chaw kub-cuam tshuam thaum lub sijhawm khov ntawm qhov vuam; qhov sib koom ua ke ntawm lub tshuab vuam laser tes tuav, kev ntxhov siab koom nrog vuam thiab kev hloov pauv thermal, thiab lwm yam. Tab sis qhov tseem ceeb tshaj plaws yog qhov cuam tshuam ntawm qhov sib txawv ntawm cov khoom ntawm cov ntaub ntawv vuam rau ntawm cov khoom macro thiab micro ntawm qhov vuam.
Cov ntaub ntawv twg tuaj yeem ua tautshuab laser welding tes tuavvuam?
1. Cov hlau tsis xeb
Cov hlau tsis xeb muaj cov coefficient siab ntawm kev nthuav dav thermal, thiab nws yooj yim overheating thaum lub sijhawm vuam. Thaum thaj chaw cuam tshuam los ntawm cua sov loj me ntsis, nws yuav ua rau muaj teeb meem loj deformation. Txawm li cas los xij, cua sov tsim los ntawm lub tshuab laser vuam tes thaum lub sijhawm vuam tag nrho yog qis. Ua ke nrog cov thermal conductivity qis, tus nqi nqus hluav taws xob siab thiab kev ua haujlwm yaj ntawm cov hlau tsis xeb, cov vuam zoo, du thiab zoo nkauj tuaj yeem tau txais tom qab vuam.
2. Cov hlau carbon
Cov hlau carbon ib txwm tuaj yeem vuam ncaj qha los ntawm kev siv tes tuav laser vuam, qhov cuam tshuam zoo ib yam li kev vuam hlau stainless, thiab thaj chaw cuam tshuam los ntawm cua sov me dua, tab sis thaum vuam cov hlau nruab nrab thiab siab carbon, qhov kub seem yog qhov siab, yog li nws tseem tsim nyog yuav tsum vuam ua ntej vuam. Kev ua kom sov thiab khaws cia cua sov tom qab vuam kom txo qhov kev ntxhov siab thiab zam kev tawg. Ntawm no peb tuaj yeem tham txog lub tshuab vuam txias. Cov hlau nruab nrab thiab siab carbon tuaj yeem vuam lossis kho ntawm qhov qeeb qeeb nrog kev vuam txias thiab cov hlau cam khwb cia vuam hlau. Hais txog kev tswj qhov kub thiab txias, kev tswj qhov kub thiab txias, thiab kev tswj qhov kub, lub tshuab vuam txias tuaj yeem qhia kev vuam laser vuam tes tuav zoo dua ntawm cov cua sov seem tom qab vuam.
3. Tuag hlau
Nws yog qhov tsim nyog rau kev vuam ntau hom hlau tuag, thiab cov nyhuv vuam zoo heev.
4. Txhuas thiab txhuas hlau
Cov txhuas thiab cov hlau txhuas yog cov khoom siv uas muaj kev cuam tshuam zoo heev, thiab qhov porosity yuav tshwm sim hauv lub pas dej molten lossis ntawm cov hauv paus thaum lub sijhawm vuam. Piv nrog rau cov khoom siv hlau yav dhau los, cov hlau txhuas thiab cov hlau txhuas muaj cov kev xav tau siab dua rau cov kev teeb tsa, tab sis tsuav yog cov kev teeb tsa vuam xaiv tau tsim nyog, cov vuam seam nrog cov khoom siv kho tshuab zoo ib yam li cov hlau hauv paus tuaj yeem tau txais.
5. Tooj liab thiab tooj liab hlau
Lub thermal conductivity ntawm tooj liab muaj zog heev, thiab nws yooj yim ua rau tsis nkag mus thiab ib nrab fusion thaum lub sijhawm vuam. Feem ntau, cov khoom siv tooj liab raug cua sov thaum lub sijhawm vuam los pab vuam. Ntawm no peb tab tom tham txog cov khoom siv tooj liab nyias. Kev vuam laser tes tuav tuaj yeem ncaj qha vuam, vim nws lub zog concentrated thiab kev vuam ceev ceev, tsis tshua cuam tshuam los ntawm lub thermal conductivity siab ntawm tooj liab.
6. Vuam ntawm cov ntaub ntawv sib txawv
Lub tshuab vuam laser uas tuav tes tuaj yeem ua tau ntawm ntau yam hlau sib txawv, xws li tooj liab-nickel, nickel-titanium, tooj liab-titanium, titanium-molybdenum, tooj dag-tooj liab, carbon tsawg hlau-tooj liab thiab lwm yam hlau sib txawv. Kev vuam laser tuaj yeem ua tiav hauv txhua qhov xwm txheej (roj lossis kub).
Lub tshuab vuam laser tes tam sim no yog cov khoom siv dav hauv kev lag luam vuam, feem ntau vim tias txawm hais tias cov khoom siv no zoo li kim dua, nws tuaj yeem txuag cov nqi zog ua haujlwm zoo heev. Tus nqi zog ua haujlwm ntawm cov neeg vuam yog kim heev. Siv cov khoom no daws qhov teeb meem ntawm kev nrhiav neeg ua haujlwm kim thiab nyuaj. Ntxiv mus, lub tshuab vuam laser tes tau txais kev qhuas los ntawm ntau txhiab tus neeg siv khoom vim nws lub neej ua haujlwm ntev thiab kev siv hluav taws xob tsawg.
