Nrog kev txhim kho ntxiv ntawm kev tsim cov khoom lag luam hauv txhua qhov chaw ntawm lub neej, daim ntawv thov ntawm laser vuam tshuab hauv ntau daim teb yog nrov dua. Tshwj xeeb nyob rau hauv kev tsim khoom, tsheb kev lag luam, kev lag luam hluav taws xob, biomedicine, hmoov metallurgy, thiab lwm cov teb, cov tsoos kev tsim khoom tsis tuaj yeem ua kom tau raws li qhov xav tau, es tsis txhob siv laser vuam tshuab.
Kev ua lag luam xav tau rau cov khoom siv laser vuam yog qhov siab dua thiab siab dua, thiab muaj ntau qhov kev ntsuas qhov cuam tshuam uas cuam tshuam qhov zoo ntawm qhov laser vuam tshuabCov. Yog li, dab tsi tsim nyog them rau thaum nriav cov khoom siv laser vuam? Tom ntej no, peb yuav muab qee qhov kev qhia rau koj.
1. Lub zog ntawm laser mem tes
Lub zog ntawm laser pulse hais txog qhov siab tshaj plaws tsim tawm lub zog ntawm ib qho laser pulse, hauv J (joule). Muaj qee lub zog, lub zog ntawm lub zog ntawm ib lub tshuab laser zuj zus, qhov qis qis tshaj tawm tsawg zaus. Lub zog ntawm laser mem tes yog qhov tseem ceeb tshaj plaws ntawm laser, uas txiav txim siab lub zog siab tshaj plaws ntawm laser.
2. Ua kom pom qhov taub ntawm lub laser chaw
Kev tsom xam txoj kab uas hla ntawm qhov chaw laser yog qhov tseem ceeb tseem ceeb uas ua rau muaj kev cuam tshuam kev tsim qauv ntawm lub laser. Chav ntsuas yog hli, uas txiav txim siab lub zog ceev thiab kev ua ntau yam ntawm lub laser. Yog hais tias lub teeb pom kev zoo laser tsim nyog thiab tsim nyog, lub zog laser lub zog thiab ua kom pom tseeb yog qhov tseeb, qhov laser pom qhov ntev tuaj yeem tswj tau qhov ntau ntawm 0.2mm-1.5mm, thiab seb laser lub ntsiab tsom tau tuaj yeem tswj tau hauv 0.2 hli yog qhov kev ntsuas nruj rau cov tshuab hluav taws xob laser.
Feem ntau, cov khoom siv laser ntawm cov tuam ntxhab tsuas yog xav kom txo tus nqi, kev ua ntawm cov khoom siv laser tau yooj yim thiab kev tsim qauv tsis yog qhov nyuaj, uas ua rau nws nyuaj ua kom pom tseeb meej. Lub chaw laser pom ntawm lub tshuab welding tsis tuaj yeem ncav cuag 0.2 hli ntawm tus qauv ntawm txhua qhov, uas ua rau lub chaw laser irradiation tsis loj dhau thiab qhov tshwm sim ntawm ablation ntawm lub weld tshwm. Qhov tshwm sim no tau muaj kev cuam tshuam tshwj xeeb ntawm cov ntaub ntawv ua tiav, qee zaum txawm tias Muab cov pwm pov tseg. Rau cov cuab yeej siv laser laser ua los ntawm Wuhan huab tais' s laser, qhov tsawg kawg laser qhov chaw tuaj yeem ncav mus txog 0.2 hli thiab tuaj yeem kho kho qhov cub tsis dhau li ntawm 0.2mm thiab 1.5mm, ncav mus txog qib siab thoob ntiaj teb. Qhov nruab nrab thiab me zog fais fab laser vuam cuab yeej ntawm huab tais' s laser feem ntau suav nrog kev tshaj tawm laser vuam tshuab, kho qhov muag kis tau tus mob laser vuam tshuab, laser chaw welder, thiab lwm yam.
3.Zaus ntawm laser cov mem tes
Qhov ntau zaus ntawm laser cov mem tes yog qhov muaj peev xwm muaj kev cuam tshuam ntau npaum li cas pulses lub laser tuaj yeem tsim nyob rau hauv ob, thiab chav tsev yog Hz. Noj kab hlau ua piv txwv, vuam hlau siv laser zog. Thaum lub laser fais fab tuag tas li, qhov ntau dua qhov ntau yog, qhov hluav taws xob tso zis tsawg dua ntawm txhua lub laser. Yog li no, peb yuav tsum xav txog kev ua cov txheej txheem los txiav txim siab qhov laser tawm ntau zaus thaum lub zog laser txaus rau cov hlau yaj. Noj hauv lub tshuab hluav taws xob cov tshuab hluav taws xob laser tsim los ntawm hongradium laser ua piv txwv, nws cov laser pulse zaus yog 1-100hz, uas tuaj yeem ua kom zoo thiab kho tau. Nws tuaj yeem ua tiav tiav qhov ua tiav precision ua cov khoom sib txawv thiab cov pwm ntawm cov duab sib txawv. Nws cov pob qij txha txuas tau du thiab zoo nkauj, lub vuam vuam yog tiaj thiab dawb ntawm cov kab thiab, thiab lub zog thiab tawv ntawm vuam leeg yog tsawg kawg yog sib npaug los yog tseem ntau dua qhov ntawm lub hauv paus hlau.
4. Kev xaiv ntawm cov tswv yim tswj txoj kev thiab cov qauv hluav taws xob
Thaum xaiv laser lub zog hluav taws xob waveform, feem ntau hais lus, nyob rau hauv cov xwm txheej ntawm tib lub laser lub zog cov tswv yim, qhov dav ntawm cov mem tes qhov dav, qhov loj dua qhov chaw weld; siab tshaj qhov teeb meem siab ntawm laser zog waveform, qhov tob qhov chaw weld.
