Classification ntawm laser vuam

1, Raws li kev tswj hwm, nws tuaj yeem muab faib ua phau ntawv laser vuam tshuab, tsis siv neeg laser vuam tshuab, thiab galvanometer laser vuam tshuab
2, Raws li lasers, lawv tuaj yeem muab faib ua: YAG laser vuam tshuab, semiconductor laser vuam tshuab, thiab fiber ntau laser vuam.
Muaj ob hom kev siv laser vuam: laser thermal conductivity vuam thiab laser sib sib zog nqus nqus vuam. Tus qub siv lub zog laser qis dua (105-106W/cm2). Tom qab lub workpiece absorbs lub laser, nws tsuas yog ua tiav nto melting, thiab tom qab ntawd tso siab rau kev hloov hluav taws xob los coj cov cua sov sab hauv ntawm lub workpiece los tsim lub pas dej molten. Hom vuam no muaj qhov tob fusion qhov tob thiab qhov dav dav me me. Lub tom kawg muaj lub zog laser siab ceev (106-107W / cm2), thiab lub workpiece sai yaj thiab txawm vaporizes tom qab nqus lub laser. Cov hlau melted tsim ib lub qhov me me nyob rau hauv qhov kev txiav txim ntawm lub zog siab, thiab lub laser beam tuaj yeem ncaj qha ci rau hauv qab ntawm lub qhov, ua rau lub qhov me me txuas ntxiv mus txog rau thaum lub zog siab hauv lub qhov yog sib npaug nrog qhov nro thiab lub ntiajteb txawj nqus. cov kua hlau. Thaum lub qhov me me txav raws qhov kev taw qhia vuam nrog lub laser beam, cov hlau molten nyob rau hauv pem hauv ntej ntawm lub qhov me ntws nyob ib ncig ntawm lub qhov me me ntawm lub rear, solidifying thiab tsim ib tug weld seam. Hom vuam no muaj qhov sib sib zog nqus tob thiab qhov sib piv loj. Hauv kev tsim khoom siv tshuab, tshwj tsis yog rau cov khoom nyias nyias, qhov sib sib zog nqus nqus vuam yuav tsum tau siv.
Cov hlau vapor thiab cov roj tiv thaiv tsim tawm thaum lub sij hawm sib sib zog nqus vuam siv ionization nyob rau hauv qhov kev txiav txim ntawm laser, yog li tsim plasma sab hauv thiab saum lub qhov me me. Plasma muaj kev nqus, refraction, thiab tawg los ntawm laser, yog li feem ntau hais lus, cov plasma saum lub pas dej molten yuav ua rau lub zog laser tsis muaj zog mus txog qhov chaw ua haujlwm. Thiab nws cuam tshuam rau cov nyhuv tsom ntawm cov nqaj thiab ua rau muaj kev puas tsuaj rau vuam. Feem ntau, sab tshuab tuaj yeem muab ntxiv kom tshem tawm lossis ua kom cov ntshav tsis muaj zog. Kev tsim cov qhov me me thiab cov nyhuv plasma ua rau lub cim ntawm cov yam ntxwv suab, lub teeb, thiab them nqi thaum lub sij hawm vuam txheej txheem. Kawm txog lawv txoj kev sib raug zoo nrog vuam specifications thiab weld zoo, thiab siv cov yam ntxwv cov cim qhia los saib xyuas cov txheej txheem vuam laser thiab zoo, muaj qhov tseem ceeb theoretical thiab cov txiaj ntsig zoo.
