Kev tshaj lij nyob rau hauv laser vuam hlau cov ntaub ntawv thiab aluminium alloy profiles nrog fiber ntau lub tshuab hluav taws xob yog tsim ntau yam tshiab thiab kev sib koom siab ntau dua rau cov kev tsim kev lag luam no, uas tau ua rau ntau cov tuam txhab tsim khoom tau them ntau rau lawv, tshwj xeeb tshaj yog nyob hauv cov chaw tsim khoom lag luam aerospace. Lub hauv paus tseem ceeb ntawm cov kev tshawb fawb txog kev lag luam thiab cov phiaj xwm kev txhim kho yog qhov tsim thiab tsim cov txheej txheem tsim thiab kev ua haujlwm muaj feem ntsig txog 2 D thiab 3 D Cheebtsam ntawm cov khoom siv hluav taws xob laser welding rau cov khoom siv fiber ntau, suav nrog qis thiab nruab nrab lub zog CW thiab QCW fiber ntau xa cov tshuab hluav taws xob laser.
Laser vuam cov kev ntsuas tau ua ntawm cov cuab yeej siv khoom raws li cov tshuab hluav taws xob laser sib txawv yooj yim thiab kev tswj cov roj. Daim ntawv thov ntawm kev soj ntsuam metallographic (qib-hla ntu) thiab xoo hluav taws xob kev tshaj lij los sau cov tshuab laser hluav taws xob (cov ntsiab lus tshwj xeeb, laser lub zog tsim hluav taws xob, thiab lwm yam) thiab cov khoom lag luam yooj yim (hom kev tswj roj, cov dej tso zis tawm, liquefied gas faib txujci, Laser vuam ceev, ua kom pom tseeb txoj hauj lwm chaw, thiab lwm yam) thiab lub laser vuam qauv thiab cov qauv ua rau hloov pauv hloov. Piv txwv li, kev sim tau pom qhov ua rau laser ua pa tso tawm los tsim cov qhov quav, thiab yuav ua li cas kom tau txais lub tshuab laser tsis muaj lub raj. Cov kev ntsuam xyuas no tseem tau qhia cov kev puas tsuaj los ntawm cov tshuab hluav taws xob laser thiab cov kev tsim khoom lag luam yooj yim rau laser vuam cov qauv thiab cov qauv.
Tsis ntev los no, feem ntau ntawm cov kev tshawb fawb txog kev lag luam tau tsom mus rau daim ntawv thov ntawm aluminium alloy profiles rau aerospace ntawm laser vuam siv rau cov khoom siv hlau. Lub hauv paus tseem ceeb rau cov khoom siv no tso siab rau cov kev sib txuas uas xav tau tshaj plaws, thiab laser vuam yuav tsum tsis muaj qhov tawg lossis cua. Sim ua kom paub tseeb tias lub laser vuam ntawm cov qauv tsim nyog tau txais los ua kom tiav cov txheej txheem kev ua tau zoo ntawm qhov kub siab. Qhov kev kuaj pom tau tseeb tias cov CW thiab QCW fiber ntau xa cov tshuab hluav taws xob muaj cov kws tshaj lij muaj peev xwm laser weld aluminium alloy profiles rau huab cua.
Tab sis kuv tsis paub, cov teeb meem uas tau ntsib nyob ntawm qhov ua tau zoo ntawm lub zog ntawm lub tshuab hluav taws xob laser thiab cov teeb meem yooj yim ntawm kev tsim khoom, uas txhais tau tias laser vuam yuav tsum tau lees tias kom muaj cov khoom zoo sib xws thiab ruaj khov. Lub tshuab hluav taws xob laser thiab cov khoom tsim theem pib tau tsim rau cov ntawv thov laser vuam ntawm txhua aerospace aluminium alloy profiles. Lub laser vuam ntsuas qhia tau hais tias qhov zoo ntawm cov khoom siv laser vuam tsis tuaj yeem tswj tau los ntawm kev ywj pheej yooj yim, thiab ib puag ncig cov txiaj ntsig ntawm cov khoom lag luam zoo ntawm laser vuam tsuas yog ua raws li kev sib xyaw ntawm ib lub tshuab hluav taws xob laser thiab cov kev ntsuas pib ntawm kev tsim khoom. Qhov kev tshawb nrhiav kev tshawb fawb no tseem qhia tau tias laser vuam tsis muaj kab nrib pleb thiab cov pa ya tau yooj yim kom tau txais hauv kev ua haujlwm ntawm nickel-thiab titanium-based alloy.
Laser vuam tshuab kuaj kuj tseem suav nrog muab tub lim laser vuam. Qee qhov aluminium alloy profiles thiab cov ntaub ntawv tshwj xeeb yuav tsum tau ntim nrog cov ntaub ntawv ntxiv kom tswj cov qauv ntawm cov khoom siv laser welded hlau kom tsis txhob tawg, yog li ua kom cov txheej txheem tsim nyog. Hauv lwm qhov xwm txheej, cov khoom siv hlau txig yog siv los tswj cov duab ntsuas ntawm lub laser vuam, yog li ntawd qhov chaw ntawm qhov chaw tsis huv ntawm cov laser vuam tau tsa me ntsis (kev txhim kho engineering). Cov ntawv sau tsis tu ncua tseem siv los them rau cov neeg pluag lossis txawm tias qhov tsis sib haum nyob rau hauv cov cuab yeej sib txuas ntawm cov khoom siv laser vuam siv rau cov khoom siv hlau. Lub tshuab hluav taws xob laser rub cov hlau vuam tag nrho cov txheej txheem ntawm laser vuam yog raug mob los ntawm ntau yam kev txwv tsis pub muaj. Ntau cov teeb meem yooj yim ntawm lub tshuab hluav taws xob laser thiab rub vuam txiav txim siab qhov zoo ntawm cov khoom lag luam laser welding uas yog qhov kawg hloov pauv. Raws li cov lus qhia saum toj no laser vuam kev kuaj, txhua qhov tseem ceeb ntawm cov khoom siv ntsig txog cov khoom siv tau zoo tuaj, kom cov khoom lag luam zoo ntawm laser vuam tuaj yeem lav tau.
