Hauv kev lag luam hlau niaj hnub no, vuam ua haujlwm raws li kev sib txuas ntawm cov thev naus laus zis, dav siv hauv kev tsim tsheb, khoom siv hluav taws xob, aerospace thiab lwm yam haujlwm. Txawm li cas los xij, ntau qhov kev sib tw ntev ntev tau ua rau cov neeg tsim khoom lag luam: kev siv vuam qis hauv kev tsim khoom loj, thermal deformation hnyav ntawm nyias- cov phab ntsa workpieces, tsis ruaj khov vuam zoo uas tshwm sim los ntawm kev tuav haujlwm, thiab teeb meem hauv vuam sib txawv ntawm cov hlau. Cov txheej txheem vuam tsoos, typified los ntawm TIG (Tungsten Inert Gas) vuam, yog cov paub tab thiab tus nqi- siv tau tab sis ua tsis tau raws li qhov siab - tus qauv xav tau ntawm kev tsim khoom niaj hnub no. Tawm tsam qhov keeb kwm yav dhau los no, laser vuam tau tshwm sim los ua qhov zoo tshaj plaws nrog nws qhov tshwj xeeb kev zoo, muab cov kev daws teeb meem zoo rau cov kev lag luam mob cov ntsiab lus hauv kev ua haujlwm tshwj xeeb.
1. TIG welding
TIG welding, ib txoj kev siv cov txheej txheem kev sib tw classic, siv hluav taws xob arc hluav taws xob tsim los ntawm tungsten electrode thiab cov khoom ua haujlwm kom yaj lub hauv paus hlau thiab muab tub lim hlau, thaum cov roj inert tiv thaiv thaj tsam vuam los ntawm oxidation. Nws yog qhov zoo - haum rau kev ua haujlwm yooj yim, xws li ntawm - kev tu vaj tse, me me - batch vuam ntawm cov khoom ua haujlwm tsis tu ncua, thiab vuam ntawm cov pa roj carbon tuab tuab. Nws lub zog loj tshaj plaws nyob rau hauv cov cuab yeej siv qis thiab kev ua haujlwm hloov tau yooj yim- cov kws txawj siv vuam tuaj yeem tuav txoj haujlwm vuam nyuaj thiab cov duab tsis sib xws tau yooj yim. Txawm li cas los xij, TIG vuam muaj qhov txwv tsis pub muaj kev txwv thaum daws teeb meem kev lag luam: nwstshav kub loj- thaj tsam cuam tshuam(feem ntau 5-10mm) feem ntau ua raudeformation ntawm workpiece, tshwj xeeb tshaj yog rau nyias daim hlau (tsawg dua 2 hli), uas yog feem ntau ua rau warping los yog hlawv. Tsis tas li ntawd, nws cov vuam ceev tsuas yog 1-3m / min, ua rau nwstsis muaj txiaj ntsig rau kev tsim khoom loj, thiab nws qhov zoo yogheev nyob ntawm tus welder txoj kev, ua rau inconsistent seam tsim thiab siab tsis xws luag.
2. Yog vim li caslaser vuam?
Hauv qhov sib piv, laser welding zoo daws cov ntsiab lus mob hauv cov haujlwm ua haujlwm, thiab nws cov txiaj ntsig tseem ceeb tuaj yeem nkag siab tau yooj yim los ntawm ntau qhov tseem ceeb, yooj yim -rau- nkag tsis tau. Ua ntej, lub zog laser (tseem nyob rau hauv watts) ncaj qha txiav txim siab vuam nkag mus: rau nyias stainless hlau los xij (0.5-2mm), 500-1500W ntawm lub zog laser yog txaus los tsim ib lub zog weld yam tsis tau hlawv los ntawm workpiece. Rau thicker workpieces (3-10mm), nce lub zog rau 2000-5000W enables ib zaug nkag. Qhov thib ob, nws qhov vuam ceev (feem ntau yog 4-15m / min) yog 4 mus rau 10 npaug sai dua li ntawm TIG vuam, ua kom muaj txiaj ntsig zoo hauv cov xwm txheej ntau lawm. Qhov thib peb, lub laser qhov chaw txoj kab uas hla (feem ntau 0.1-0.5mm) yog me dua li TIG arc, uas ua rau muaj zog dua ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom (tsuas yog 0.1-1mm). Qhov no zoo tiv thaiv workpiece deformation, ib qho tseem ceeb feature rau precision Cheebtsam xws li hluav taws xob connectors thiab automotive sheet hlau qhov chaw.
3. Sawv ntsug rau Precision
Hauv kev siv tshwj xeeb,laser vuamUa kom pom qhov zoo ntawm qhov tsis tuaj yeem hloov tau.Nyob rau lub zog tshiab tsheb kev lag luam ua piv txwv, Tesla Model 3 txais laser annular vuam rau nws lub cev tsheb. Rau lub laser vuam robots paub txog kev sib koom ua ke ntawm lub cev, txo cov khoom siv thiab txhim kho lub cev rigidity.Rau vuam ntawm lub cav lub tog raj kheej blocks thiab gearbox vaj tse uas yuav tsum tau zoo heev airtightness, laser micro- nkag welding yog siv los tiv thaiv cov roj thiab cua to.The lamination welding ntawm lub cev muaj zog stator hlau cores ua tiav cov kev pab cuam lub zog tshiab. welding yog siv rau cov roj teeb cell tabs (2-5mm nyob rau hauv dav), nruab nrog lub teeb pom kev zoo kom tsis txhob vuam sib txawv thiab luv luv circuits.Laser vuam rau cov khoom xws li lub rooj zaum ncej thiab cov kav dej tso tawm boosts ntau lawm efficiency, minimizes workpiece deformation, thiab adapts zoo rau kev sib dhos kab manufacturing.
TIG vuam thiab laser vuam tsis yog kev sib koom ua ke tab sis ua tiav, nrog rau lawv tus kheej siv tau ua haujlwm. TIG vuam tseem irreplaceable nyob rau hauv yooj yim kev khiav hauj lwm, tsawg- nqi thiab nyob rau hauv - qhov chaw tu scenarios.Laser vuamTxawm li cas los xij, yog tus yuam sij los daws qhov teeb meem tseem ceeb hauv kev lag luam -kev ua haujlwm qis, yooj yim deformation thiab tsis ruaj khov zoo- nyob rau hauv siab -precision, ntau lawm thiab cov khoom tshwj xeeb vuam scenarios.Cov neeg tsim khoom tuaj yeem daws qhov mob ntawm vuam cov ntsiab lus los ntawm kev xaiv qhov tsim nyog vuam txoj kev raws li cov khoom siv ua haujlwm, tuab, ntim ntau lawm thiab qhov xav tau, thiab kho lub zog laser, vuam ceev thiab qhov chaw txoj kab uas hla. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm laser technology, nws yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev txhim kho ntawm kev lag luam vuam.
