Laser vuam yog ib qho ntawm cov kev siv ntxov tshaj plaws hauv kev lag luam laser khoom. Nyob rau hauv feem ntau cov ntawv thov thaum ntxov, laser generated welds yog cov zoo dua, uas ua rau muaj zog productivity. Nrog rau txoj kev loj hlob ntawm laser hom, laser qhov chaw tam sim no muaj zog dua, sib txawv wavelengths thiab dav mem tes muaj peev xwm ntau. Tsis tas li ntawd, beam propagation, tshuab tswj kho vajtse thiab software, thiab cov txheej txheem sensors txhua tus txhawb txoj kev loj hlob tshiab ntawm laser vuam txheej txheem.
Laser vuam muaj qhov zoo tshwj xeeb, suav nrog cov khoom siv hluav taws xob tsawg, thaj tsam nqaim fusion thiab thaj chaw kub ntxhov, nrog rau cov khoom siv zoo heev ntawm cov khoom siv yav dhau los nyuaj rau kev siv cov txheej txheem uas tsim cov cua kub loj rau qhov chaw. Cov khoom no ua rau cov vuam tsim los ntawm laser welding muaj zog thiab zoo nkauj zoo nkauj. Tsis tas li ntawd, qhov teeb tsa lub sij hawm xav tau rau laser vuam yog tsawg dua. Ua ke nrog lub laser nrhiav sensor, automation tuaj yeem pom tau, yog li txo cov nqi khoom. Tag nrho cov thev naus laus zis tshiab no tau nthuav dav ntxiv rau daim ntawv thov ntau yam ntawm laser vuam. Hauv ntau qhov kev lag luam, fiber ntau laser vuam siv cov hlau sib txawv, cov duab tivthaiv, qhov ntau thiab tsawg tau ua tiav tiav.
Roj teeb vuam
Kev siv cov roj teeb lithium ntau ntxiv hauv cov tsheb hluav taws xob thiab ntau cov khoom siv hluav taws xob txhais tau tias cov engineers siv fiber ntau laser vuam hauv cov khoom tsim. Cov khoom nqa tam sim no tsim los ntawm tooj liab lossis aluminium alloy txuas nrog cov roj teeb hauv lub roj teeb los ntawm kev siv fiber ntau laser vuam. Laser vuam aluminium alloy (feem ntau yog 3000 Series) thiab ntshiab tooj liab los tsim hluav taws xob tiv tauj nrog cov electrodes zoo thiab tsis zoo ntawm lub roj teeb. Tag nrho cov ntaub ntawv thiab cov khoom siv ua ke siv hauv lub roj teeb yog cov ntaub ntawv sib tw rau cov txheej txheem fiber ntau laser vuam tshiab. Overlapping, pob tw thiab fillet welded pob qij txha ua ntau yam kev sib txuas hauv lub roj teeb. Laser vuam ntawm cov khoom lug mus rau qhov tsis zoo thiab zoo terminals yuav tsim cov khoom siv hluav taws xob sib cuag. Qhov kawg roj teeb pob sib dhos thiab vuam kauj ruam, uas yog, kev sib koom ua ke ntawm cov txhuas tuaj yeem, tsim kev thaiv rau cov electrolyte sab hauv. Txij li thaum lub roj teeb yuav tsum ua haujlwm tau zoo rau 10 xyoo lossis ntau dua, kev xaiv ntawm laser vuam tuaj yeem ua tau zoo. Siv cov khoom siv kho qhov muag fiber ntau laser vuam thiab txheej txheem, laser vuam tuaj yeem ua tau zoo welds ntawm 3000 series aluminium alloy.
Precision machining thiab vuam
Cov ntsaws ruaj ruaj siv hauv nkoj, tshuaj refineries thiab kev lag luam tshuaj tau pib TIG welded. Vim hais tias lawv tau siv nyob rau hauv ib puag ncig rhiab heev, cov khoom no yog precision machined thiab hauv av los ntawm npib tsib xee puag alloy cov ntaub ntawv uas tiv taus kub thiab tshuaj corrosion. Cov batch loj yog feem ntau me me thiab tus naj npawb ntawm cov chaw yog loj. Nws tau nkag siab tias tam sim no, kev sib dhos ntawm cov khoom siv no tau txhim kho los ntawm kev kho qhov muag fiber ntau laser vuam. Cov laj thawj ntawm kev siv fiber ntau laser vuam los hloov cov txheej txheem robotic arc vuam thaum ntxov muaj xws li: qhov zoo ntawm laser vuam zoo ib yam; Nws yog ib qho yooj yim los hloov ntawm ib qho kev teeb tsa mus rau lwm qhov, uas txo cov sij hawm teeb tsa thiab txhim kho cov zis; Tus nqi tuaj yeem raug txo los ntawm kev sib sau ua ke ntawm lub laser nrhiav sensor kom automate lub laser vuam txheej txheem.
Gas nruj vuam
Hermetically kaw cov khoom siv hluav taws xob hauv kev kho mob xws li pacemakers thiab lwm yam khoom siv hluav taws xob tau ua fiber ntau laser vuam cov txheej txheem nyiam rau cov ntawv thov uas xav tau kev ntseeg siab tshaj plaws. Txoj kev loj hlob tshiab ntawm cov txheej txheem roj nruj vuam tau daws cov teeb meem ntsig txog laser vuam thiab vuam kawg taw tes, uas yog txoj haujlwm tseem ceeb ua kom tiav cov roj nruj sealing. Yav dhau los laser vuam tshuab yuav ua rau muaj kev nyuaj siab ntawm qhov kawg taw tes thaum lub laser beam raug muab tua, txawm tias thaum lub zog laser txo. Advanced laser beam tswj tshem tawm kev nyuaj siab nyob rau hauv nyias thiab sib sib zog nqus welds. Qhov tshwm sim yog zoo ib yam weld zoo, tsis muaj porosity ntawm qhov kawg taw tes, txhim kho tsos thiab txhim khu kev qha sealing.
Aerospace vuam
Fiber laser welding ntawm npib tsib xee thiab titanium raws li aviation alloys yuav tsum tswj weld geometry thiab weld microstructure, nrog rau txo qhov porosity thiab tswj cov qoob loj. Hauv ntau daim ntawv thov aerospace, kev qaug zog ntawm welds yog qhov tseem ceeb tsim qauv. Yog li ntawd, tus tsim engineers yuav luag ib txwm hais tias lub vuam nto yog convex los yog me ntsis convex los txhim kho lub vuam lub zog. Rau lub hom phiaj no, ib tug filling kab nrog ib txoj kab uas hla ntawm 1.2 hli yog siv rau cov txheej txheem automated. Qhov sib ntxiv ntawm cov xaim xaim mus rau lub pob tw sib koom ua ke yuav ua rau muaj cov kab sib xws nyob rau sab saum toj thiab hauv qab. Los ntawm kev ua kom cov microstructure zoo ntawm cov vuam, kev xaiv ntawm vuam hlau alloy kuj tseem ua rau cov khoom siv ntawm cov vuam.
Qhov sib txawv ntawm cov hlau vuam
Lub peev xwm los tsim cov khoom siv sib txawv hlau thiab alloys zoo heev txhim kho qhov yooj ntawm kev tsim thiab kev tsim khoom. Optimizing cov khoom ntawm cov khoom tiav, xws li corrosion, hnav thiab kub tsis kam, thaum tswj cov nqi, yog ib qho kev txhawb siab rau cov hlau sib txawv. Kev sib txuas stainless hlau thiab galvanized hlau yog ib qho piv txwv. Vim lawv cov corrosion kuj zoo heev, 304 stainless hlau thiab galvanized carbon hlau tau siv dav hauv ntau daim ntawv thov, xws li cov khoom siv hauv chav ua noj thiab cov khoom siv dav hlau. Cov txheej txheem no nthuav tawm qee qhov kev sib tw tshwj xeeb, tshwj xeeb tshaj yog vim zinc txheej yuav ua rau muaj teeb meem loj weld porosity. Thaum lub sij hawm welding, lub zog rau yaj hlau thiab stainless hlau yuav evaporate zinc ntawm li 900 degree, uas yog qis dua qhov melting point ntawm stainless hlau. Qhov qis qis ntawm zinc ua rau tsim cov ncu thaum lub qhov tseem ceeb vuam. Thaum sim khiav tawm molten hlau, zinc vapor yuav nyob twj ywm hauv cov khoom sib txuas, uas ua rau muaj qhov porosity ntau dhau ntawm qhov vuam. Qee zaum, zinc vapor yuav khiav tawm nrog cov khoom sib txuas ntawm cov hlau, tsim cov pores lossis roughness ntawm qhov chaw vuam. Kev ua tiav thiab kev siv tshuab vuam tuaj yeem ua tau yooj yim los ntawm kev tsim qauv tsim thiab xaiv cov txheej txheem laser. Tsis muaj cov kab nrib pleb los yog qhov hws ntawm sab sauv thiab sab hauv ntawm lub puab tsaig welds ntawm 304 stainless hlau nrog lub thickness ntawm 0.6 hli thiab galvanized hlau nrog ib tug tuab ntawm 0.5 hli.
