Kev Sawv Cev ntawm Kev Txiav Txim Siab Yav Tom Ntej

Laser welding yog ib qho kev siv thev naus laus zis uas siv lub tshuab hluav taws xob laser siab kom ua tiav cov khoom sib txuas, feem ntau yog hlau, los ntawm melting lawv ntawm qhov chaw sib cuag.

Cov txheej txheem no tsim kom muaj zog, ruaj khov nrog tsawg deformation piv rau cov txheej txheem vuam tsoos.

Nws yog ceev ceev, ua tau zoo, thiab muaj peev xwm ua tau cov txiaj ntsig zoo.

Lub plawv ntawm Laser Vuam

Nyob rau hauv lub plawv ntawm laser vuam yog lub laser beam nws tus kheej, uas generates immense cua sov.

Thaum lub laser yog teem rau ntawm ib tug hlau nto, nws melts cov khoom, ua ib tug me me molten pas dej ua ke.

Lub pas dej no solidifies sai, feem ntau nyob rau hauv milliseconds, ib zaug lub laser txav deb, ua rau muaj kev sib txuas ntawm qhov chaw.

Cov txheej txheem yog tswj tau heev, txhais tau hais tias tsuas yog cov cheeb tsam raug welded raug cuam tshuam, tawm hauv cov khoom seem tsis cuam tshuam.

Nkag siab txog Laser Vuam

Ib txoj hauv kev yooj yim kom nkag siab txog laser vuam yog xav txog lub iav tsom iav tsom rau lub hnub rays mus rau qhov chaw me me.

Ib yam li lub teeb tsom tuaj yeem yaj ib daim ntawv, lub teeb laser tsom lub zog hnyav rau ntawm cov hlau.

Ua rau nws yaj thiab, qee zaum, txawm tias vaporize.

Lub zog ceev ntawm Laser Beam Vuam

Lub zog ntawm lub laser yog ntsuas raws li lub zog ceev.

Uas yog qhov siab kawg - ncav cuag lab watts ib square centimeter.

Lub zog ntawm lub laser ntau dua, qhov vuam txheej txheem tuaj yeem ua tau sai, thiab qhov sib sib zog nqus cua sov tuaj yeem nkag mus rau cov khoom siv.

Txawm li cas los xij, lub zog laser ntau dua kuj ua rau tus nqi ntawm cov khoom siv.

Ua rau nws yog ib qho tseem ceeb thaum xav txog tag nrho cov nqi ntawm lub tshuab.

Nd: YAG lasers yog qhov zoo tagnrho rau cov haujlwm tshwj xeeb xws li kho pwm, tab sis lawv cov kev siv hluav taws xob tsawg thiab cov nqi kho mob siab tuaj yeem txwv.

Thaum kawg, diode lasers muab kev ua haujlwm zoo heev tab sis tsis tshua muaj txiaj ntsig thaum xav tau siab precision.

Fiber Laser Vuam: Feem ntau nrov & pov thawj

Fiber lasers yog tam sim no nrov tshaj plaws thiab pov thawj technology rau laser vuam.

Lawv paub txog lawv lub zog ua haujlwm siab, nyob ib ncig ntawm 30%.

Uas pab hauv kev tswj xyuas thermal zoo dua thiab txo cov nqi khiav haujlwm.

Lub infrared wavelength tawm los ntawm fiber ntau lasers yog zoo-absorbed los ntawm feem ntau hlau.

Ua rau lawv muaj txiaj ntsig zoo rau ntau yam kev ua haujlwm welding.

Ib qho ntawm qhov zoo tshaj plaws ntawm fiber ntau lasers yog lawv lub peev xwm los tsim thiab coj cov teeb ci laser los ntawm fiber ntau optic cable.

Qhov no tso cai rau cov kab teeb pom kev zoo, nce qhov tseeb, thiab lub zog ntau dua, uas ua rau muaj qhov tob tob tob thaum vuam.

Tsis tas li ntawd, fiber ntau lasers muaj kev siv tsawg tsawg ntawm cov khoom siv, txo cov nqi kho thiab kev nyuaj.

Lawv kuj tuaj yeem ua ke yooj yim nrog cov neeg hlau lossis CNC tshuab, ua rau lawv muaj ntau yam hauv kev lag luam.

Lwm qhov txiaj ntsig yog qhov tsis muaj kev txwv rau lub zog ntawm fiber ntau lasers, ua kom muaj kev ua haujlwm siab zoo txawm tias cov ntaub ntawv tuab.

CO2 Laser: Zoo rau qee yam kev siv

CO2 lasers yog thawj hom laser siv rau kev lag luam laser vuam thiab tseem siv rau hauv qee yam kev siv.

Cov lasers emit ib tug roj-raws li laser beam uas tsis tuaj yeem coj los ntawm fiber ntau optics.

Uas ua rau qis qis qis dua piv rau fiber ntau lasers.

Qhov no ua rau lawv tsis tshua meej rau qee qhov kev siv vuam.

CO2 lasers feem ntau yog siv rau vuam voj voog workpieces vim hais tias lub laser yuav kho nyob rau hauv txoj hauj lwm thaum lub workpiece rotates.

Txawm li cas los xij, lawv xav tau kev saib xyuas ntau dua vim qhov xav tau ntau zaus rau cov khoom siv xws li iav thiab gases.

Nrog rau qhov nruab nrab lub zog ua haujlwm ntawm ib puag ncig 20%, CO2 lasers tsis muaj zog npaum li fiber ntau lasers.

Ua rau cov nqi khiav lag luam ntau dua.

Nd:YAG Laser: Pov thawj nrog kev txwv

Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) lasers yog cov cuab yeej pov thawj hauv laser vuam

Tab sis lawv tuaj nrog qee qhov kev txwv.

Lawv muaj kev siv hluav taws xob tsawg, feem ntau nyob ib ncig ntawm 5%.

Uas ua rau muaj teeb meem kev tswj xyuas thermal thiab cov nqi khiav lag luam ntau dua.

Ib qho ntawm qhov muaj zog ntawm Nd:YAG lasers yog lawv lub peev xwm los coj lub teeb ci laser siv fiber ntau optics, uas txhim kho cov nqaj zoo.

Txawm li cas los xij, nws tseem nyuaj rau tsom mus rau lub teeb ci laser ntawm qhov chaw me me, txwv lawv qhov tseeb hauv qee yam kev siv.

Nd: YAG lasers feem ntau yog siv rau cov haujlwm tshwj xeeb xws li kho pwm, qhov kev ua kom pom tseeb loj dua tuaj yeem siv tau.

Lawv kuj muaj cov nqi kho mob siab, vim tias cov khoom siv xws li iav thiab teeb yuav tsum tau hloov tsis tu ncua.

Diode Laser: nyuaj rau tsom vim qhov tsis zoo ntawm cov nqaj zoo

Diode lasers tau dhau los ua ntau dua hauv cov ntawv thov uas xav tau lub zog ua haujlwm siab (kwv yees li 40%).

Qhov kev ua haujlwm siab no ua rau kev tswj xyuas thermal zoo dua thiab cov nqi ua haujlwm qis dua piv rau lwm hom laser.

Txawm li cas los xij, ib qho ntawm cov teeb meem loj ntawm diode lasers yog tias lawv cov nqaj zoo tsis zoo.

Uas ua rau nws nyuaj rau tsom lub laser ntawm qhov chaw me me.

Qhov no txwv lawv cov precision hauv qee qhov kev siv vuam.

Txawm li cas los xij, diode lasers tseem muaj txiaj ntsig zoo rau qee yam khoom siv, tshwj xeeb yog cov yas, thiab tuaj yeem siv tau zoo hauv cov ntawv thov.

Conduction & Keyhole Laser Vuam

Nkag siab txog cov txheej txheem vuam siv

Laser vuam tuaj yeem muab faib ua ob hom tseem ceeb: kev siv vuam vuam thiab keyhole vuam.

Ob txheej txheem no txawv ntawm qhov laser cuam tshuam nrog cov khoom thiab cov txiaj ntsig lawv tsim.

Qhov txawv tseem ceeb

Vuam Zoo

Kev siv vuam feem ntau ua rau cov txiaj ntsig zoo dua nrog qhov tsis sib xws thiab tsawg dua qhov tsis xws luag, thaum lub qhov tseem ceeb vuam tuaj yeem ua rau tawg ntau dua, qhov porosity, thiab qhov loj dua qhov cuam tshuam los ntawm tshav kub.

Vuam Thaum tshav kub kub Distribution

Kev siv vuam faib cov cua sov sib npaug ntawm txhua qhov kev taw qhia, thaum lub qhov tseem ceeb vuam tsom rau cua sov hauv qhov nqaim dua, kev coj ncaj ncaj, ua rau kev nkag mus tob dua.

Vuam ceev

Keyhole welding yog ceev dua, ua rau nws haum rau high-volume ntau lawm, thaum conduction vuam qeeb dua tab sis muaj ntau precision.

Kev cob qhia vuam

Conduction welding yog txheej txheem maj mam thiab qeeb. Nyob rau hauv txoj kev no, lub laser beam melts saum npoo ntawm cov hlau.

Ua rau cov hlau ncav cuag nws qhov kub thiab txias (qhov taw tes uas nws hloov mus ua kua).

Tab sis tsis txhob mus dhau qhov ntawd mus rau qhov kub ntawm vaporization (qhov twg hlau yuav tig mus rau hauv roj).

Cov cua sov sib npaug sib npaug thoob plaws hauv cov khoom siv, txhais tau tias cov cua sov hloov mus rau txhua qhov kev qhia hauv cov hlau.

Vim hais tias conduction welding melts cov khoom maj mam, nws ua tau zoo dua.

Qhov no suav nrog me me spatter (cov tee me me ntawm cov khoom molten uas tuaj yeem khiav tawm thaum lub vuam) thiab cov pa taws tsawg, ua rau cov txheej txheem huv.

Txawm li cas los xij, vim tias nws qeeb qeeb, kev siv vuam siv feem ntau yog siv rau cov ntawv thov uas xav tau qhov tseeb thiab cov pob qij txha zoo dua li qhov nrawm.

Keyhole Vuam

Keyhole welding, ntawm qhov tod tes, yog txheej txheem nrawm dua thiab nruj dua.

Nyob rau hauv txoj kev no, lub laser beam melts thiab vaporizes cov hlau, tsim ib tug me me, sib sib zog nqus qhov los yog keyhole nyob rau hauv cov khoom.

Lub laser qhov kub hnyiab ua rau cov hlau mus txog ob qho tib si nws qhov kub thiab txias vaporization.

Nrog qee lub pas dej molten tig mus rau hauv cov pa roj.

Vim hais tias cov khoom yog vaporized, lub tshav kub yog pauv mus rau perpendicular mus rau lub laser beam, uas ua rau ib tug sib sib zog nqus, nqaim weld pas dej ua ke.

Cov txheej txheem no nrawm dua li kev siv vuam, ua rau nws zoo tagnrho rau cov kab ntau lawm.

Txawm li cas los xij, qhov kub ceev thiab khaus khaus tuaj yeem ua rau tawg, thiab cov melting sai kuj tuaj yeem ua rau cov porosity (cov pa npuas me me nyob hauv qhov vuam).

Thiab ib cheeb tsam loj dua tshav kub-tshem tawm (HAZ) (qhov chaw nyob ib puag ncig cov vuam uas hloov pauv los ntawm cov cua sov).
