Xov Xwm - Cov ntawv thov tseem ceeb ntawm lasers hauv kev lag luam

Txij li thaum nws tshwm sim hauv xyoo 1960, cov thev naus laus zis laser tau tsim kho sai sai rau hauv cov cuab yeej tseem ceeb hauv kev lag luam tsim khoom lag luam vim nws lub zog ceev ceev, kev coj ua zoo thiab kev tswj hwm. Piv nrog rau cov txheej txheem ua khoom siv ib txwm muaj, kev ua laser muaj cov txiaj ntsig zoo xws li tsis sib cuag, kev ua haujlwm siab thiab qib siab ntawm kev ua haujlwm tsis siv neeg, thiab siv dav hauv kev tsim khoom lag luam xws li kev txiav cov khoom siv, vuam, cim, khawb thiab kev tsim khoom ntxiv. Raws li hom laser thiab nws cov yam ntxwv ntawm cov txheej txheem, kev ua laser kev lag luam feem ntau muab faib ua peb pawg: kev txiav laser, kev vuam laser thiab kev tsim khoom ntxiv laser. Txhua txoj kev ua haujlwm muaj nws cov txheej txheem tshwj xeeb ntawm kev ua haujlwm thiab qhov ntau thiab tsawg ntawm daim ntawv thov.

Kev txiav laser

Kev txiav laser yog ib qho ntawm cov ntawv thov laser kev lag luam uas laus tshaj plaws. Nws siv lub teeb laser muaj zog heev los yaj thiab ua pa cov khoom, thiab ua ke nrog cov roj pabcuam los tshuab cov slag tawm, ua tiav kev txiav zoo thiab meej. CO₂ lasers thiab fiber lasers tam sim no yog cov khoom siv tseem ceeb, tsim nyog rau kev txiav cov phaj nruab nrab thiab nyias ntawm cov ntaub ntawv xws li carbon hlau, stainless hlau, thiab txhuas alloy. Qhov zoo ntawm cov thev naus laus zis no yog nws qhov nqaim, thaj chaw me me uas cuam tshuam los ntawm cua sov, tsis tas yuav pwm thiab muaj peev xwm hloov pauv txoj hauv kev ua tiav sai. Nws yog qhov tshwj xeeb tshaj yog rau cov lag luam xav tau siab xws li kev tsim tsheb, kev ua cov hlau ntawv thiab aerospace.

Hauv kev tsim tsheb, kev txiav laser siv los tsim ntau yam khoom xws li cov vaj huam sib luag ntawm lub cev mus rau lub cav. Piv txwv li, cov laser fiber siv rau kev txiav cov khoom siv hlau muaj zog siab, yog li ua rau lub tsheb tsis hnyav.

(2) Kev lag luam aerospace kuj tau txais txiaj ntsig los ntawm kev siv tshuab laser txiav, tshwj xeeb tshaj yog hauv kev tsim cov khoom sib xyaw ua los ntawm cov khoom siv siab heev xws li titanium thiab cov khoom sib xyaw. Piv txwv li, ultrafast lasers tuaj yeem siv los txiav cov khoom sib xyaw titanium nrog cov duab sib xyaw, thaum txo qis kev puas tsuaj thermal thiab ua kom muaj kev ncaj ncees ntawm cov khoom, ua rau muaj kev ua tau zoo thiab kev nyab xeeb ntawm cov khoom aerospace.

Kev vuam laser

Kev vuam laser ua tiav kev sib txuas los ntawm kev yaj sai sai cov khoom siv hlau nrog lub teeb laser, muaj qhov nkag mus tob, ceev ceev, thiab qis cua sov nkag. Cov hom vuam feem ntau suav nrog kev vuam laser tas mus li thiab kev vuam laser pulsed, uas tsim nyog rau cov phaj nyias precision vuam thiab cov xwm txheej vuam nkag mus tob. Piv rau kev vuam arc, laser weld seams muaj zog dua thiab tsawg dua deformation, thiab siv tau rau hauv cov teb xws li roj teeb ntim, stainless hlau Cheebtsam vuam, thiab nuclear fais fab qauv Cheebtsam tsim khoom. Tshwj xeeb hauv kev tsim roj teeb, laser vuam tau dhau los ua txoj kev sib txuas tseem ceeb.

(1) Hauv kev lag luam tsheb, kev vuam laser yog siv los txuas cov vaj huam sib luag ntawm lub cev, cov khoom siv cav, thiab lwm yam khoom tseem ceeb. Piv txwv li, cov laser fiber yog siv rau kev vuam qhov tseeb ntawm cov khoom siv hlau muaj zog siab los tsim cov pob qij txha muaj zog thiab ruaj khov.

(2) Hauv kev lag luam hluav taws xob, kev vuam laser yog siv rau kev sib txuas siab ntawm cov khoom me me thiab meej. Piv txwv li, diode lasers yog siv los vuam cov roj teeb hauv cov roj teeb lithium-ion kom ntseeg tau tias muaj kev ntseeg siab ntawm kev sib txuas hluav taws xob.

(3) Hauv kev lag luam aerospace, Boeing 787 Dreamliner siv cov thev naus laus zis laser vuam los txuas cov titanium alloys thiab cov ntaub ntawv sib xyaw, txo cov lej ntawm cov rivets, txo qhov hnyav ntawm lub fuselage, thiab txhim kho kev siv roj.

Kev siv tshuab laser, ua ib lub hauv paus tseem ceeb ntawm kev tsim khoom siab heev, tab tom nthuav dav nws cov ciam teb ntawm kev siv lag luam. Tam sim no, kev ua laser kuj tseem tab tom txhim kho mus rau lub zog siab dua, qhov tseeb dua thiab ntau txoj kev sib koom ua ke, xws li laser-electric arc composite welding, laser ultrafast micro-processing, thiab laser intelligent monitoring systems. Yav tom ntej, nrog rau kev nce qib tas mus li ntawm high-power semiconductor lasers, intelligent control systems, thiab green manufacturing concepts, laser processing yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev tsim khoom ntse, cov khoom lag luam tus kheej, thiab cov khoom siv ua tiav heev.
