Laser vuam tshuabtau tshawb fawb txij thaum yug los ntawm lasers nyob rau hauv 1960s.Nws tau ntsib ze li ntawm 40 xyoo ntawm txoj kev loj hlob los ntawm kev vuam ntawm nyias qhov me me los yog cov cuab yeej siv rau cov ntawv thov loj tam sim no ntawm lub zog laser vuam hauv kev tsim khoom.Nws tau kawm kom meej nyob rau hauv thaum ntxov 20th caug xyoo.Thawj lub laser tau tsim nyob rau hauv 1960. Plaub xyoo tom qab, lub ntiaj teb thawj YAG solid-state laser thiab CO2 roj laser tau tsim.Txij thaum ntawd los, laser vuam tshuab tau siv dav hauv ntau hom kev lag luam.
1.Qhov zoo ntawmlaser vuam tshuabpiv nrog cov txheej txheem vuam tsoos
① Ua ntej qhov tshwm sim ntawm laser vuam, kev lag luam kev lag luam tau siv cov txheej txheem vuam tsoos.Vim qhov tsis sib xws hauv zos cua sov thiab txias ntawm cov vuam, tom qab vuam deformation feem ntau tshwm sim, yog li ua tsis tau raws li qhov xav tau ntawm vuam, thiab vim qhov vuam tsis meej txaus, kuj tseem yuav muaj kev sib txuam tsis tiav ntawm cov khoom ua haujlwm thiab cov hlau vuam lossis txheej weld, thiab cov weld muaj cov slag non-metallic, uas absorbs roj thiab generates pores thiab lwm yam tsis xws luag, uas feem ntau ua rau cov welded qhov chaw tawg thiab cuam tshuam rau sealing kev ua tau zoo.
② Laser vuam muaj qhov zoo ntawm lub zog siab ceev, me me deformation, nqaim tshav kub cuam tshuam cheeb tsam, siab vuam ceev, yooj yim tsis siv neeg tswj, thiab tsis ua raws li cov txheej txheem.Nyob rau hauv xyoo tas los no, nws tau dhau los ua ib qho tseem ceeb ntawm cov khoom siv hlau ua thiab kev tsim khoom.Ntau thiab ntau tau siv dav hauv tsheb, aerospace, kev lag luam tiv thaiv, nkoj tsim, marine engineering, khoom siv hluav taws xob nuclear thiab lwm yam, cov ntaub ntawv koom nrog yuav luag tag nrho cov ntaub ntawv hlau.
③ Txawm hais tias piv nrog cov txheej txheem vuam tsoos, laser vuam tseem muaj teeb meem ntawm cov cuab yeej kim, kev nqis peev loj ib zaug thiab cov kev xav tau siab, uas ua rau kev lag luam ntawm laser vuam hauv kuv lub teb chaws tsis tshua muaj, tab sis laser vuam muaj kev ua haujlwm siab thiab yog ib qho yooj yim kom paub tsis siv neeg Tswj cov yam ntxwv ua rau nws zoo tagnrho rau cov kab ntau lawm thiab hloov tau yooj yim.
④ Tam sim no, hlau vuam muaj ntau dua thiab siab dua qhov yuav tsum tau ua rau vuam lub zog thiab zoo li.Cov txheej txheem vuam tsoos yuav ua rau muaj teeb meem xws li kev cuam tshuam thiab deformation ntawm lub workpiece vim nws cov cua kub zoo heev.Txhawm rau tsim kom muaj qhov teeb meem deformation, yuav tsum muaj ntau qhov kev soj ntsuam xyuas, uas ua rau tus nqi nce ntxiv.Lub siab tsis siv neeg laser vuam txoj kev muaj qhov tsawg tshaj plaws tshav kub input thiab tsis tshua muaj hluav taws kub cuam tshuam cheeb tsam, uas ho txhim kho qhov zoo ntawm welded workpiece, txo cov nqi ua hauj lwm tom qab, thiab zoo heev txhim kho vuam efficiency thiab stability.
2.Cov qauv sib txawv, ntau yam kev xaiv
Hauv cov ntsiab lus, cov tshuab laser vuam tam sim no yog qhov paub tab heev.Laser vuam tshuabmuaj tsawg zog noj, siab precision, thiab me ntsis ib puag ncig muaj kuab paug.Ntau thiab ntau cov kev lag luam thev naus laus zis tau xaiv laser vuam tshuab kom paub meej cov khoom zoo thiab ua kom cov tuam txhab thiab cov neeg siv khoom.
