Nyob rau niaj hnub no kev tsim muaj kev lag luam kev lag luam, laser technology tau dhau los ua lub zog tseem ceeb uas tsav txoj kev loj hlob ntawm kev lag luam tsim nrog nws cov kev ua tau zoo thiab ntau yam kev siv. Ntawm lawv, YAG pulsed pwm laser vuam tshuab, raws li cov khoom siv vuam siab heev, ua lub luag haujlwm txiav txim siab hauv cov teb xws li pwm tsim thiab kho nrog nws qhov tshwj xeeb zoo. Lub hauv paus ntawm YAG pulsed pwm laser vuam tshuab yog nyob rau hauv kev saws yttrium aluminium garnet (YAG) muaju raws li cov khoom siv laser. Lub teeb xenon pulsed, raws li lub zog excitation qhov chaw, kis ntau lub zog rau YAG muaju, yog li stimulating high-zog pulsed laser beams. Lub laser beam no muaj lub zog ceev heev, muab lub hauv paus ruaj khov rau kev ua tiav qhov tseeb thiab siv tau zoo vuam. Nyob rau hauv cov nqe lus ntawm kev ua hauj lwm hauv paus ntsiab lus, lub YAG pulsed pwm laser vuam tshuab ua rau tag nrho cov kev siv ntawm cov yam ntxwv ntawm lasers. Thaum lub zog high-zog pulsed laser beam tsom thiab irradiated mus rau saum npoo ntawm cov pwm yuav tsum tau welded, nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm, lub nto ntawm cov khoom instantaneously heats li, mus txog lub melting point los yog txawm lub boiling point, sai sai. melts thiab fuses ua ke, yog li ua tiav cov txheej txheem vuam. Vim lub zog laser muaj zog heev, qhov vuam cheeb tsam tuaj yeem tswj tau qhov tseeb, ua rau nws muaj peev xwm ua tau zoo vuam ntawm cov pwm me me thiab ua kom ntseeg tau qhov siab precision thiab zoo ntawm vuam.
Qhov zoo ntawm YAG pulsed pwm laser vuam tshuab muaj ntau heev. Ua ntej, nws tuaj yeem ua tiav qhov vuam me me, feem ntau mus txog qib micron. Qhov no high-precision welding muaj peev xwm ua rau cov vuam ntawm cov pwm pwm nrog cov duab nyuaj thiab qhov me me tsis muaj zog, ua kom zoo dua ntawm kev tsim pwm. Qhov thib ob, nws txoj kev vuam nrawm nrawm yog qhov zoo kawg li. Piv rau cov txheej txheem vuam tsoos, nws tuaj yeem ua tiav cov haujlwm vuam hauv lub sijhawm luv luv, txhim kho kev tsim khoom thiab ua tau raws li qhov xav tau ntawm kev tsim khoom sai hauv kev lag luam niaj hnub. Thib peb, thaj tsam me me uas cuam tshuam rau tshav kub yog lwm qhov zoo dua. Thaum lub sij hawm vuam txheej txheem, thermal puas rau cov ntaub ntawv nyob ib puag ncig yog negligible, zoo tswj lub zuag qhia tag nrho kev ua tau zoo thiab mechanical qauv ntawm cov pwm, txo qhov seem deviations thiab degradation los ntawm thermal deformation. Nyob rau hauv cov xwm txheej thov siv tau, YAG pulsed pwm laser vuam tshuab ua kom pom kev siv dav. Txawm hais tias nws yog ntau hom pwm xws li kho vajtse pwm, yas pwm, lossis pwm pwm tuag, nws tuaj yeem ua tau zoo heev. Rau cov teeb meem xws li kev hnav khaub ncaws, cov kab nrib pleb zoo, thiab cov teeb meem hauv cheeb tsam uas tshwm sim thaum lub sij hawm siv pwm mus ntev, YAG pulsed pwm laser vuam tshuab tuaj yeem ua cov kev kho kom raug, rov ua kom lawv rov qab mus rau lawv lub xeev qub lossis txawm tias lawv qhov kev ua tau zoo tshaj qub. Los ntawm kev kho kom raws sijhawm thiab ua tau zoo, tsis yog tsuas yog kev pabcuam lub neej ntawm cov pwm ntev, txo cov nqi tsim khoom ntawm cov tuam txhab, tab sis kuj muaj kev cuam tshuam ntau lawm los ntawm pwm kev puas tsuaj raug txo, ua kom muaj kev ruaj khov thiab ruaj khov ntawm kev tsim khoom. Txawm li cas los xij, kom ua tiav qhov zoo ntawm YAG pulsed pwm laser vuam tshuab, qee qhov teeb meem tseem ceeb yuav tsum tau muab sau tseg. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia nruj nruj kom nkag siab tob txog kev ua haujlwm, txheej txheem kev ua haujlwm, thiab kev tiv thaiv kev nyab xeeb ntawm cov khoom siv. Tsuas yog los ntawm kev paub txog kev txawj ntse muaj peev xwm tuaj yeem ua haujlwm zoo ntawm cov cuab yeej thiab kev ruaj ntseg ntawm vuam zoo. Lub caij no, nws yog ib qho tseem ceeb rau kev kho cov vuam tsis zoo raws li cov yam ntxwv ntawm cov khoom pwm sib txawv (xws li hardness, melting point, thermal conductivity, thiab lwm yam) thiab cov kev xav tau tshwj xeeb vuam (xws li vuam dav, qhov tob, lub zog, thiab lwm yam). Cov tsis muaj xws li lub zog laser, mem tes dav, zaus, vuam ceev, thiab lwm yam, thiab lawv cov kev sib txuas tsim nyog cuam tshuam ncaj qha rau vuam cov nyhuv thiab zoo. Saib mus rau yav tom ntej, nrog kev nce qib thiab kev tsim kho tshiab ntawm laser tshuab, YAG pulsed pwm laser vuam tshuab kuj tseem yuav hloov kho thiab txhim kho tsis tu ncua. Kev siv hluav taws xob ntau dua, kev tswj xyuas vuam zoo dua, thiab kev ua haujlwm ntse ntau dua yuav ua tau. Nws ntseeg tau tias nyob rau yav tom ntej, nws yuav ua lub luag haujlwm tseem ceeb tshaj plaws hauv kev tsim pwm thiab lwm yam kev lag luam, ua rau muaj zog ntau dua los txhawb kev txhim kho kev lag luam zoo.
