kiv puag ncig ntawm vuam tshuab |Laser Vuam rau Aluminium Alloy
Aluminium alloys yog dav siv nyob rau hauv ntau yam welded structural khoom vim lawv lub teeb yuag, siab zog, zoo corrosion kuj, non-magnetic zog, zoo formability thiab zoo kub tsis zoo.Thaum vuam nrog aluminium alloys, qhov hnyav ntawm cov khoom siv welded tuaj yeem raug txo los ntawm 50% piv nrog cov welded hauv steel daim hlau.Tam sim no, qhov no tau siv dav hauv ntau yam lag luam xws li aviation, aerospace, tsheb, roj teeb fais fab, kev tsim khoom, nkoj tsim, qhov rooj thiab qhov rais, tshuaj lom neeg kev lag luam thiab cov khoom siv niaj hnub.
Advanced laser vuam tshuab rau aluminium alloy
Laser vuam tshuab rau txhuas alloy yog ib tug tshiab technology tsim nyob rau hauv lub xyoo caum kawg.Nws nta ntawm kev ua haujlwm muaj zog, kev ntseeg siab thiab kev ua haujlwm siab hauv kev sib piv nrog cov txheej txheem vuam tsoos.Ntawm no yog qhov zoo ntawm laser welded aluminium alloys:
▪ Lub zog ua kom sov, qis tshav kub tawm, tsis tshua muaj cua sov, nqaim melting cheeb tsam thiab kub-cuam tshuam qhov tob.
▪ Microfine weld qauv vim qhov txias txias thiab kev sib koom ua haujlwm zoo.
▪ Laser vuam yam tsis muaj electrodes, txo tus txiv neej-teev thiab nqi.
▪ Cov duab ntawm welded workpiece tsis cuam tshuam los ntawm electromagnetism thiab tsis tsim X-rays.
▪ Muaj peev xwm vuam cov khoom siv hlau hauv cov khoom pob tshab kaw.
▪ Laser tuaj yeem kis tau mus ntev nrog cov fibers optical, uas ua rau cov txheej txheem hloov tau.Nrog cov khoos phis tawj thiab cov neeg hlau, cov txheej txheem vuam tuaj yeem siv tau thiab tswj tau meej.
Qhov zoo rau kev soj ntsuam nrog kub-kho aluminium alloys
Ua kom cov txheej txheem ceev
Ua kom cov khoom ua tau zoo thiab txhim kho cov vuam zoo los ntawm kev txo cov cua sov nkag.
Thaum welding high-strength thiab loj-thickness aluminium alloys, nws tuaj yeem yooj yim ua tiav vuam los ntawm ib qho dhau los ntawm kev tsim qhov tob ntawm qhov tseem ceeb hauv qhov uas laser sib sib zog nqus vuam vuam thiab cov nyhuv keyhole tshwm sim, uas muaj zog dua li cov txheej txheem vuam.
Kev sib piv rau ntau qhov chaw laser hauv laser vuam ntawm aluminium alloys
Niaj hnub no, cov khoom siv laser tseem ceeb hauv kev lag luam yog CO2 laser, YAG laser thiab fiber ntau laser.Vim nws lub zog ua haujlwm siab, CO2 laser yog qhov tsim nyog rau cov phaj tuab tuab, tab sis qhov nqus ntawm CO2 laser beam nyob rau saum npoo ntawm aluminium alloy yog me me, uas ua rau ntau lub zog poob thaum lub vuam txheej txheem.
YAG laser feem ntau me me nyob rau hauv lub hwj chim, qhov nqus tus nqi ntawm YAG laser beam nyob rau saum npoo ntawm aluminium alloy yog loj dua li ntawm CO2 laser, muaj fiber ntau optical conduction, muaj zog adaptability, yooj yim txheej txheem, thiab lwm yam, qhov tsis zoo ntawm YAG: lub tso zis zog thiab photoelectric conversion zog yog tsawg.
Fiber laser muaj qhov zoo ntawm qhov me me, tsis tshua muaj nqi khiav lag luam, kev pab lub neej ntev, kev ruaj ntseg zoo thiab siab beam zoo.Lub caij no, lub teeb tawm los ntawm fiber ntau laser yog 1070nm wavelength nrog tus nqi nqus siab dua, photoelectric hloov dua siab tshiab yog 10 npaug siab dua YAG laser, thiab vuam ceev nrawm dua YAG thiab CO2 laser.
Vuam Technology Revolution
Lub zog loj laser vuam cov cuab yeej yuav tsum tau siv rau hauv aluminium alloy vuam
Raws li cov txheej txheem welding high-zog-density, laser vuam tuaj yeem tiv thaiv qhov tsis xws luag los ntawm cov txheej txheem vuam tsoos, thiab vuam lub zog coefficient kuj yuav txhim kho zoo heev.Nws tseem yog ib qho nyuaj rau siv lub tshuab hluav taws xob qis qis rau vuam aluminium alloy tuab daim hlau, tsis yog vim tias qhov nqus ntawm lub laser beam ntawm aluminium alloy nto yog tsawg heev, tab sis kuj tseem muaj qhov teeb meem pib tshwm sim thaum xav tau. sib sib zog nqus welding.
Qhov muag pom zoo tshaj plaws ntawm aluminium alloy laser vuam tshuab yog nws cov kev ua haujlwm siab, uas yog siv rau qhov loj-thickness sib sib zog nqus-ntev vuam rau kev siv.Thiab qhov loj-thickness sib sib zog nqus welding tshuab yuav yog ib qho kev txhim kho uas tsis tuaj yeem nyob rau yav tom ntej.Nyob rau hauv lwm txoj kev, qhov loj-thickness sib sib zog nqus nqus vuam qhov tseem ceeb lub pinhole phenomenon thiab nws cuam tshuam rau weld porosity, uas ua rau lub mechanism ntawm pinhole tsim thiab nws tswj tau txais ib qho tseem ceeb, thiab nws yuav muaj tseeb ua ib tug kiv puag ncig nyob rau hauv vuam ntiaj teb yav tom ntej.
