Nrog txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, kev txuas ntxiv mus thiab kev paub tab ntawm kev siv tshuab laser, peb lub tshuab laser vuam kuj tseem tau zoo dua thiab zoo dua, thiab laser vuam tshuab yog dav siv hauv cov pwm pwm, cov hniav nyiaj hniav kub, cov khoom siv hluav taws xob, cov khoom lag luam, thiab lwm yam. cov tuam txhab tsim ntawm laser vuam tshuab kuj tseem loj hlob tuaj, thiab kev siv tshuab laser vuam siv, txawm hais tias tus kheej lossis tuam txhab lag luam tseem nthuav dav li cas peb tuaj yeem txhim kho kev ua haujlwm ntawm laser vuam tshuab thaum peb siv nws los ua cov khoom lag luam? Tam sim no cia' s tham txog yuav ua li cas txhawm rau txhim kho kev ua haujlwm ntawm kev ua haujlwm ntawm lub tshuab tsis siv neeg laser welding?
Ntau lub chaw tsim khoom yuav ntsib qee cov teeb meem hauv cov txheej txheem ntawm kev siv lub tshuab ua lub ntsej muag siv lub tshuab ua puv laser. Piv nrog kev lag luam laser ua kev lag luam, lub tshuab welding laser tsis yog qhov tshiab, tab sis kom nkag siab txog lub tshuab ua lub tshuab ua laser tag nrho tseem xav tau peb txoj kev kawm thiab kev sib tham ntxiv. Cov kev ua haujlwm ntawm kev siv lub tshuab tsis siv neeg laser yuav tau kho kom zoo rau qee yam. Feem ntau hais lus, muaj plaub yam raws li hauv qab no:
1. Ua ntej txhua, kev ceev fais fab yog ib qho tseem ceeb tshaj plaws hauv kev siv lub tshuab tsis siv neeg laser welding. Nrog lub zog hluav taws xob kom nruj, txheej txheej yuav raug rhaub kom kub taw rau hauv microsecond lub sijhawm ntau, ua rau muaj vaporization ntau. Yog li ntawd, qhov siab zog hluav taws xob tau txais txiaj ntsig zoo rau cov khoom siv tshem tawm, xws li drilling, txiav thiab carving. Rau qis fais fab tuag ceev, nws yuav siv ob peb milliseconds rau qhov kub kom mus txog qhov kub npau npau. Ua ntej lub ntsej muag vaporization, txheej hauv qab ncav lub melting point, uas yog yooj yim los ua qhov zoo fusion vuam.
2. Qhov thib ob, qhov nthwv ntawm laser lub mem tes yeej ib txwm yog qhov teeb meem tseem ceeb hauv laser vuam tshuab, tshwj xeeb tshaj yog nyob rau hauv cov ntawv vuam. Thaum lub tshuab hluav taws xob laser siab heev nto rau saum npoo ntawm cov khoom siv, 60% - 98% ntawm lub zog laser ntawm cov hlau saum npoo yuav cuam tshuam thiab ploj, thiab qhov cuam tshuam yuav hloov nrog qhov kub. Thaum lub caij laser mem tes, qhov kev cuam tshuam ntawm hlau sib txawv ntau.
3. Tom qab ntawd qhov thiaj li hu tias mem tes dav ntawm lub laser mem tes yog qhov tseem ceeb tshaj plaws hauv qhov tseem ceeb rau cov mem tes laser vuam siv tshuab. Nws tsis yog tsuas yog ntsuas tseem ceeb txawv ntawm kev tshem tawm cov khoom siv thiab cov khoom tso tawm, tab sis tseem yog qhov tseem ceeb rau kev txiav txim siab tus nqi thiab ntim ntawm cov khoom siv.
4. Thaum kawg, tus cawv ntawm kev tsom rau tus nqi ntawm kev ua haujlwm zoo yuav tsum paub rau txhua tus phooj ywg uas ua haujlwm ntawm laser vuam tshuab. Feem ntau, laser vuam yuav tsum tau ua kom pom tseeb. Vim tias lub zog fais fab ntawm qhov chaw nruab nrab ntawm lub laser focal point yog siab dhau, nws yog qhov yooj yim kom ua rau evaporation rau hauv qhov. Qhov faib tawm ntawm lub zog ceev yog qhov sib txawv hauv cov dav hlau kom deb ntawm lub hom phiaj laser.
