Qhov zoo thiab qhov tsis zoo ntawm Laser Vuam ntawm Aluminium Alloy
Thaum laser vuam aluminium alloy, ib yam li vuam ntawm galvanized steel phaj, ntau qhov pores thiab tawg yuav raug tsim thaum lub sij hawm vuam, uas yuav cuam tshuam rau vuam zoo.Cov khoom siv txhuas muaj lub zog ionization tsawg, tsis zoo vuam ruaj khov, thiab tseem yuav ua rau vuam tsis ua haujlwm.Ntxiv nrog rau txoj kev vuam kub kub, aluminium oxide thiab aluminium nitride yuav raug tsim nyob rau hauv tag nrho cov txheej txheem, ua rau muaj kuab paug rau ib puag ncig.
Txawm li cas los xij, aluminium alloy phaj nto tuaj yeem polished ua ntej welding kom nws nqus ntawm laser zog;Inert gas yuav tsum tau siv thaum lub sij hawm welding los tiv thaiv cov cua qhov.
Laser arc hybrid vuam ntawm aluminium alloy tau daws cov teeb meem ntawm laser vuam fais fab, nqus ntawm laser beam rau saum npoo ntawm aluminium alloy thiab qhov pib tus nqi ntawm kev sib sib zog nqus welding.Nws yog ib qho tseem ceeb tshaj plaws aluminium alloy vuam txheej txheem.Tam sim no, cov txheej txheem tsis paub tab thiab nyob rau theem tshawb fawb thiab tshawb nrhiav.
Qhov nyuaj ntawm laser vuam yog txawv rau txawv aluminium alloys.Cov kev kho cua sov uas tsis muaj zog ntxiv dag zog rau txhuas thiab txhuas alloy 1000 series, 3000 series thiab 5000 series muaj qhov zoo weldability;4000 series alloy muaj tsawg heev tawg rhiab heev;Rau 5000 series alloy, thaum ω Thaum (Mg) = 2%, cov hlau ua tawg.Nrog rau qhov nce ntawm magnesium cov ntsiab lus, qhov vuam kev ua tau zoo yog txhim kho, tab sis cov ductility thiab corrosion kuj ua tsis zoo;2000 series, 6000 series thiab 7000 series alloys muaj qhov xav tau loj rau kub tawg, tsis zoo weld tsim, thiab txo qhov tseem ceeb hauv kev laus tom qab vuam hardness.
Yog li ntawd, rau lub laser vuam ntawm aluminium alloy, nws yog ib qho tsim nyog yuav tau txais cov txheej txheem tsim nyog thiab xaiv cov txheej txheem vuam thiab cov txheej txheem kom tau txais txiaj ntsig zoo.Ua ntej vuam, kev kho deg ntawm cov ntaub ntawv, kev tswj cov txheej txheem vuam thiab kev hloov cov qauv vuam yog txhua txoj hauv kev zoo.
Kev xaiv ntawm vuam parameter
· Laser zog 3KW.
· Laser vuam ceev: 4m / min.Qhov vuam ceev nyob ntawm lub zog ceev.Qhov siab dua lub zog ceev, qhov vuam ceev ceev.
· Thaum lub phaj yog galvanized (xws li 0.8mm rau sab phab ntsa sab nrauv phaj thiab 0.75mm rau sab saum toj npog txheej phaj), kev sib dhos clearance yog tswj los ntawm qhov chaw, feem ntau 0.05 ~ 0.20mm.Thaum lub vuam yog tsawg dua 0.15 hli, zinc vapor tsis tuaj yeem raug tshem tawm ntawm qhov sib txawv ntawm sab, tab sis raug tshem tawm ntawm qhov chaw vuam, uas yooj yim los tsim cov porosity tsis xws luag;Thaum qhov dav dav dav dua 0.15 hli, cov hlau molten tsis tuaj yeem ua tiav qhov sib txawv, ua rau lub zog tsis txaus.Thaum lub weld thickness yog tib yam li ntawm cov phaj, cov khoom siv kho tshuab yog qhov zoo tshaj plaws, thiab qhov dav weld nyob ntawm qhov ua kom pom txoj kab uas hla;Qhov tob weld nyob ntawm lub zog ceev, vuam ceev thiab tsom txoj kab uas hla.
· Lub shielding roj yog argon, ntws yog 25L / min, thiab kev khiav hauj lwm siab yog 0.15 ~ 0.20MPa.
· Tsom txoj kab uas hla 0.6 mm.
· Kev tsom xam txoj hauj lwm: thaum lub phaj thickness yog 1 hli, qhov tsom tsuas yog nyob rau saum npoo, thiab txoj hauj lwm ua kom pom tseeb nyob ntawm cov duab ntawm lub khob hliav qab.
