Tam sim no, handheld laser vuam tshuab tau dav siv nyob rau hauv lub tshav pob ntawm hlau vuam. Nyob rau hauv ib txwm welding teb, 90% ntawm cov hlau vuam tau raug hloov los ntawm laser vuam vim lub laser vuam ceev yog ntau tshaj tsib npaug ntawm cov tsoos vuam txoj kev, thiab cov nyhuv vuam yog deb tshaj li cov tsoos argon arc vuam thiab shielded vuam. Laser welding nyob rau hauv lub vuam ntawm cov hlau uas tsis yog-ferrous xws li txhuas alloy muaj qhov zoo ntawm cov tsoos vuam txoj kev. Ntawm chav kawm, nyob rau hauv cov nqe lus ntawm vuam hlau cov ntaub ntawv, handheld laser vuam tshuab kuj muaj ib co kev ceev faj.
Thawj kauj ruam yog los xyuas kom meej tias lub shutter reflector yog huv si, vim hais tias tsis huv lo ntsiab muag yuav puas tau thaum siv, uas thaum kawg yuav ua rau unrepairable tsis ua hauj lwm. Thaum lub laser yog npaj txhij mus tom qab nws kiag li tuned. Nrog rau txoj kev loj hlob ntawm laser vuam tshuab, handheld laser vuam tshuab yog maturing thiab tau siv nyob rau hauv ib tug ntau yam ntawm industrial teb. Txawm li cas los xij, hauv cov txheej txheem niaj hnub tsim thiab siv, vim muaj ntau yam laj thawj, tseem yuav muaj qee yam teeb meem. Yog li, kev tswj hwm thiab daws cov teeb meem no uas cuam tshuam rau kev ua haujlwm zoo yog qhov tseem ceeb tshaj plaws. Feem ntau, peb txiav txim siab qhov ua rau ntawm qhov teeb meem los ntawm txoj kev phenomena thiab tswj cov kev hloov pauv.
Feem ntau, muaj ob qho laj thawj rau kev ua haujlwm tsis zoo:
1. Yog tias muaj teeb meem nrog kev ua cov khoom siv, cov khoom siv tsis raug yuav tsum tau hloov pauv kom ua tiav qhov xav tau.
2. Kev teeb tsa ntawm cov kev ntsuas tsis tu ncua yuav tsum muaj kev soj ntsuam tas li ntawm tib yam khoom raws li cov khoom siv welded thiab kev sib tham raws li cov txiaj ntsig ntawm kev xeem.
Tsis tas li ntawd, laser vuam muaj ntau yam zoo uas cov tsoos vuam tsis tuaj yeem phim:
1. Kev nyab xeeb. Lub qhov hluav taws xob nozzle tsuas yog pib ua haujlwm thaum nws los rau hauv kev sib cuag nrog hlau, txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis raug, thiab qhov kov hloov ntawm lub vuam teeb feem ntau muaj qhov ntsuas kub, uas yuav cia li nres ua haujlwm thaum nws kub dhau.
2. Txhua lub kaum ntse ntse vuam tuaj yeem ua tiav. Laser welding tsis yog tsuas yog siv tau rau cov pa welds xwb, tab sis kuj muaj kev hloov kho siab heev thiab kev siv vuam zoo hauv cov welds nyuaj, cov khoom ntim loj, thiab cov welds tsis zoo.
3. Laser vuam tuaj yeem pab tswj kev ua haujlwm huv hauv lub hoobkas. Laser vuam muaj tsawg spatter thiab muaj kev ruaj ntseg vuam zoo, uas tuaj yeem txo cov pa phem hauv lub hoobkas thiab xyuas kom muaj chaw ua haujlwm huv.
Txawm li cas los xij, laser vuam kuj tseem muaj qee qhov yuav tsum tau ua hauv cov txheej txheem thov tiag tiag, xws li kev siv tus qauv zoo dua rau cov khoom siv laser vuam, thiab txhim kho thiab ua kom zoo dua cov txheej txheem hlau hlau. Laser vuam kuj tseem muaj qhov yuav tsum tau ua kom raug thiab kho kom zoo. Yog tias koj xav muab kev ua si tag nrho rau qhov zoo ntawm laser vuam, txo cov nqi thiab txhim kho kev ua haujlwm, nws yog ib qho tsim nyog los ua kom zoo dua cov txheej txheem ntawm cov ntawv hlau lossis lwm yam hlau hauv kev tsim khoom tiag tiag. Xws li cov khoom tsim, laser txiav, stamping, dabtsi yog khoov, laser vuam, thiab lwm yam., kho dua tshiab txoj kev vuam rau laser vuam, tuaj yeem txo cov nqi tsim khoom ntawm lub Hoobkas txog li 30%, thiab laser vuam tau dhau los ua kev xaiv ntawm ntau lub lag luam.
Qhov nyuaj ntawm aluminium alloy laser vuam:
1. Aluminium alloy muaj cov yam ntxwv ntawm lub teeb yuag, tsis muaj hlau nplaum, tsis kub tsis kam, corrosion kuj, yooj yim sib sau, thiab lwm yam., yog li nws yog dav siv nyob rau hauv kev lag luam vuam. Siv aluminium alloy hloov steel phaj vuam tuaj yeem txo qhov hnyav ntawm cov qauv los ntawm 50%.
2. Aluminium alloy vuam yog yooj yim los tsim pores.
3. Lub linear expansion coefficient ntawm aluminium alloy weld yog loj, uas yog feem ntau yuav ua rau deformation thaum vuam.
4. Thermal expansion yog nquag tshwm sim thaum lub sij hawm txhuas alloy vuam, ua rau thermal tawg.
5. Qhov teeb meem loj tshaj plaws rau kev nrov nrov thiab kev siv aluminium alloy yog qhov muag muag loj ntawm cov pob qij txha welded thiab lub zog qis coefficient.
6. Qhov saum npoo ntawm aluminium alloy yog ib qho yooj yim los tsim ib lub refractory oxide zaj duab xis (lub melting point ntawm A12O3 yog 2060 ° C), uas yuav tsum tau muaj lub hwj chim-ntsuas vuam txheej txheem.
7. Aluminium alloy muaj thermal conductivity siab (kwv yees li 4 npaug ntawm cov hlau), thiab nyob rau hauv tib lub vuam ceev, lub tshav kub input yog 2 mus rau 4 npaug ntawm welded steel thiab. Yog li ntawd, aluminium alloy welding yuav tsum muaj zog ceev, tsis tshua muaj vuam kub input thiab siab vuam ceev.
