Thaum siv lub tshuab laser welding handheld, kev xaiv ntawm shielding gas ncaj qha cuam tshuam rau vuam tsim zoo thiab kev pab cuam lub neej ntawm cov cuab yeej.
Feem ntau siv shielding gases muaj xws li nitrogen, argon, carbon dioxide, thiab sib xyaw gases. Cov roj sib txawv tuaj yeem tsim cov txiaj ntsig sib txawv nyob ntawm cov khoom siv welded thiab cov ntawv thov tshwj xeeb.
Can Handheld Laser Vuam Tshuab Siv Cua rau Vuam?
Nyob rau hauv xyoo tas los no, qee qhov kev sib tham hauv kev ua lag luam tau hais tias laser vuam tuaj yeem ua tau ncaj qha los ntawm kev siv huab cua los tiv thaiv roj.
Nyob rau hauv kev muaj tiag, huab cua welding yuav ua tau ib tug tej yam vuam nyhuv, tab sis nws yog feem ntau tsis pom zoo rau cov khoom uas yuav tsum tau zoo weld zoo.
Thaum lub sij hawm laser vuam, shielding gases feem ntau inert gases. Lawv lub hom phiaj tsis yog tsuas yog los tiv thaiv lub vuam seam tab sis kuj tiv thaiv lub lens tiv thaiv sab hauv lub taub hau vuam.
Ob Lub Luag Haujlwm Tseem Ceeb ntawm Shielding Gas
1. Tiv thaiv Weld Oxidation
Thaum lub sij hawm laser welding, thaj chaw hlau molten ncav cuag qhov kub thiab txias tuaj yeem ua rau cov pa oxygen hauv huab cua yooj yim.
Shielding gas cais thaj chaw vuam los ntawm cov pa oxygen, txo cov vuam vuam oxidation thiab pab ua kom zoo dua vuam zoo thiab ruaj khov zoo.
2. Tiv thaiv lub lens tiv thaiv
Thaum tuav laser vuam, spatter, pa taws, thiab hlau hais yog generated.
Yog tias tsis muaj kev tiv thaiv cov roj ntws tas mus li, cov kab mob no tuaj yeem nkag mus rau hauv lub taub hau vuam thiab ua rau lub ntsej muag tiv thaiv, cuam tshuam rau cov khoom siv laser thiab muaj peev xwm tiv thaiv lub laser los ntawm kev ua haujlwm zoo.
Qhov twg zoo dua: Nitrogen lossis Argon?
Raws li kev siv vuam kev paub, nitrogen thiab argon muab cov vuam zoo sib xws hauv cov ntawv thov feem ntau.
Piv txwv li:
Thaum vuam stainless hlau, ob lub gases tuaj yeem ua tiav cov txiaj ntsig zoo.
Thaum vuam aluminium, cov roj xaiv yuav txawv nyob ntawm seb cov txheej txheem tshwj xeeb yuav tsum tau ua.
Hauv kev siv tiag tiag, cov neeg siv tuaj yeem xaiv raws li qhov chaw muaj roj av thiab cov nqi khiav haujlwm. Qhov kev xaiv yooj yim dua thiab kev lag luam feem ntau yog nyiam.
Vim li cas Air Welding tsis pom zoo?
Huab cua muaj cov pa oxygen, thiab cov pa oxygen txhawb cov hlau oxidation.
Vuam Stainless hlau
Yog tias cov hlaws hlaws yuav tsum tau ua kom muaj lub ntsej muag zoo, xws li kub lossis nyiaj - xim dawb, nws nyuaj rau ua tiav qhov xav tau thaum siv cua vuam.
Vim oxidation, weld hlaws tej zaum yuav dub, daj, los yog discolored.
Vuam Carbon Steel
Cov pa roj carbon steel ib txwm muaj qhov tsos tsaus nti, yog li cov xim hlau yuav tsum qis dua. Txawm li cas los xij, kev siv cua welding tuaj yeem ua rau:
Nce weld porosity
Ntau yam tsis xws luag
Tsis ruaj tsis khov vuam zoo
Yog li ntawd, nyob rau hauv ib txwm muaj ntau lawm, huab cua feem ntau tsis pom zoo raws li ib tug shielding roj tshwj tsis yog tias cov khoom tsis muaj tshwj xeeb yuav tsum tau rau vuam zoo.
Xaus
Rau handheld laser vuam tshuab,nitrogen los yog argon yog pom zoo raws li lub shielding gas. Ob lub gases tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm feem ntau cov ntawv thov vuam.
Kev xaiv ntawm shielding gas feem ntau yog nyob ntawm:
Hom vuam khoom
Weld zoo li xav tau
Muaj cov pa roj hauv zos
Tus nqi khiav haujlwm
Kev xaiv zoo ntawm cov khoom siv tiv thaiv roj, ua ke nrog cov khoom siv laser uas tsim nyog, yog qhov tseem ceeb rau kev ua tiav qib siab - cov txiaj ntsig laser vuam zoo thiab txhim kho cov khoom ruaj khov.
