Nrog rau kev txhim kho txuas ntxiv ntawm lasers, laser vuam tshuab tau nce ntxiv qhia lawv cov kev txawj ntse hauv daim ntawv hlau vuam. Piv txwv li, laser vuam tshuab siv qhov chaw vuam tshuab los vuam aluminium-plated steel. Thaum welding aluminized steel daim hlau, cov teeb meem dab tsi yuav tsum tau them rau? Dab tsi yog kev kho mob ntawm aluminized steel phaj yuav tsum tau mus txog kom ua tiav lub hom phiaj ntawm vuam? Cov txheej txheem txheej txheem hlau tsuas tuaj yeem siv tau rau hauv cov kauj ruam tom ntej tom qab dhau los ntawm cov txheej txheem ntawd.
Thaum lub tshuab laser vuam siv qhov chaw vuam txheej txheem los ua cov ntawv txhuas-plated steel, nws yuav tsum muaj kev soj ntsuam zoo dua tam sim no thiab ze dua cov txheej txheem vuam dua li cov ntawv txias-dov. Nyob rau tib lub sijhawm, kev saib xyuas electrode tseem ceeb heev thiab yuav tsum tau kho txhua lub sijhawm kom tsis txhob deformation ntawm qhov chaw sib cuag. Yog li ntawd, cov khoom tsis yog xim hlau yuav doped hauv kev tsim cov hlau aluminized. Lub aluminized steel phaj yog steel phaj nrog txhuas-silicon alloy txheej, uas muaj 90 feem pua ntawm txhuas thiab 10 feem pua ntawm silicon. Cov txheej txheem ntawm aluminized steel muaj qhov sib txawv siab dua li cov hlau galvanized. Nws yog ib qho yooj yim mus ntws thiab muaj me me melting cheeb tsam, yog li tsis tas yuav tsum tau siv tam sim no loj li vuam galvanized hlau. Nyob rau tib lub sijhawm, muaj cov pa phem tsawg heev uas ua rau lub sijhawm vuam, uas tuaj yeem tiv thaiv ib puag ncig zoo.
Qhov chaw vuam txheej txheem ntawm lub tshuab laser vuam tau siv los ua kom tiav qhov vuam ntawm aluminium-plated steel. Txawm li cas los xij, tom qab vuam, muaj ib txheej ntawm cov khoom siv grey-dub ntawm lub vuam seam. Cov khoom siv grey no yog sab laug tom qab cov tshuaj tiv thaiv ntawm silicon. Cov residue no tuaj yeem ntxuav tau los ntawm kev siv cov tshuaj muaj zog acidic los ntxuav, tab sis nws ua txhaum lub tswv yim ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, yog li tshiab thiab ntsuab tu txoj kev yog qhov zoo tshaj plaws.
Nws tau hais tias lub laser yog omnipotent. Nws tuaj yeem tsis tsuas yog vuam hlau, tab sis kuj siv cov cuab yeej huv. Kev siv cov cuab yeej siv laser los ntxuav cov welds tuaj yeem tsis tsuas yog ntxuav cov khoom seem tab sis kuj yuav tsis ua mob rau cov hauv paus hniav, nws kuj yog ib txoj kev ntxuav ntsuab thiab ib puag ncig zoo.
Cov txheej txheem ntxuav ntawm cov khoom siv laser yog nyob ntawm cov yam ntxwv ntawm lub teeb mem tes tsim los ntawm lub laser, raws li cov tshuaj tiv thaiv photophysical tshwm sim los ntawm kev sib cuam tshuam ntawm cov nqaj siv siab, lub laser luv-pulse, thiab cov pa phem txheej.
Laser tu yog ib txoj kev tu "ntsuab". Nws tsis tas yuav siv cov tshuaj thiab cov kua dej huv. Cov khib nyiab pov tseg yog cov hmoov hmoov, me me, yooj yim khaws cia, rov ua dua tshiab, thiab tuaj yeem daws tau yooj yim cov teeb meem los ntawm kev siv tshuaj ntxuav. Environmental pollution teeb meem; qhov tsis sib tsoo thiab tsis sib cuag ntawm laser tu ua rau cov teeb meem no yooj yim los daws; lub laser tuaj yeem kis tau los ntawm fiber ntau optical, thiab nws tuaj yeem siv nrog cov neeg hlau thiab cov neeg hlau kom yooj yim ua haujlwm ntev. Nws tuaj yeem ntxuav qhov chaw uas tsis yooj yim mus txog los ntawm cov txheej txheem ib txwm ua kom cov neeg ua haujlwm muaj kev nyab xeeb; laser ntxuav tuaj yeem tshem tawm txhua yam kev ua qias tuaj rau ntawm qhov chaw ntawm ntau yam ntaub ntawv kom ua tiav qhov kev huv uas tsis tuaj yeem ua tiav los ntawm kev tu cov pa, thiab nws tuaj yeem xaiv cov pa phem ntawm cov khoom tsis ua rau cov khoom puas.
