Hauv kev vuam laser, kev xaiv cov roj tiv thaiv kom zoo yog ib qho ntawm cov yam tseem ceeb uas txiav txim siab qhov zoo ntawm kev vuam. Cov roj tiv thaiv tsis tsuas yog txhim kho qhov du ntawm qhov chaw vuam thiab txo qis oxidation los ntawm kev sib cuag
ntawm lub pas dej ua kua thiab huab cua ib puag ncig, tab sis kuj tseem txo qhov kev ua qias tuaj ntawm lub lens, tiv thaiv txoj kev pom sab hauv ntawm lub tshuab vuam, thiab txuas lub neej ua haujlwm ntawm cov khoom siv.Tshuab vuam laser portable
cov txiaj ntsig muaj feem cuam tshuam nrog kev xaiv roj - cov kauj ruam tseem ceeb no yuav tsum tsis txhob raug saib tsis taus.
Cov Haujlwm ntawm Shielding Gas
Kev Tiv Thaiv Thawj Zaug ntawm Oxidation thiab Kev Ua Phem:Cais cov pas dej ua los ntawm cov hlau thiab cov hlau vuam ntawm huab cua hauv qhov chaw vuam kub siab, tiv thaiv kev oxidation thiab kev nqus cov khoom tsis huv.
Kev Txhim Kho Thib Ob ntawm Kev Tsim Weld:Txo cov spatter thiab ua rau weld smoothness, uniformity, thiab tsos.
Kev Tiv Thaiv Huab Cua Inert: Los ntawm kev tsim kom muaj ib puag ncig inert nyob ib puag ncig thaj chaw vuam, cov roj tiv thaiv ua lub luag haujlwm tseem ceeb hauv:
Kev Thaiv Thib Peb Kev Cuam Tshuam Huab Cua:Tiv thaiv tau zoo rau cov pa oxygen, nitrogen, thiab cov dej noo hauv huab cua los ntawm kev cuam tshuam nrog lub pas dej ua kom sov siab, zam kev porosity, oxidation inclusions, thiab lwm yam.
qhov tsis zoo.
Cov Cheebtsam Khoom Siv Tiv Thaiv Thib Plaub:Txo cov dej phwj rau ntawm lub lens ntawm rab phom vuam, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm txoj kev pom los ntawm kev oxidation lossis xeb, thiab ncua lub sijhawm txij nkawm.
Cov Lus Qhia Txog Kev Siv Roj Tiv Thaiv
Argon
Raws li cov roj inert siv dav tshaj plaws hauv kev vuam, argon muaj kev ruaj khov tshuaj zoo heev thiab muaj peev xwm txhawb nqa arc. Nws qhov ceev siab tso cai rau nws los tsim ib txheej npog ruaj khov hla lub pas dej molten, tsim kom zoo nkauj
zoo siab laser cov khoom siv vuamNws yog qhov tshwj xeeb tshaj yog rau kev vuam cov hlau uas yooj yim oxidation xws li stainless hlau, aluminium alloys, thiab titanium alloys.
Nitrogen
Rau cov ntaub ntawv xws li hlau tsis hnyav thiab hlau tsis tshua muaj hlau sib xyaw, nitrogen yog qhov kev xaiv pheej yig, muab qhov tsis sib haum xeeb thiab kev lag luam zoo. Hauv qee cov hlau, nws tuaj yeem txhim kho qhov tawv ntawm qhov chaw, tab sis thaum kub siab, nws yuav
ua xua nrog cov hlau hauv paus. Kev tsim nyog yuav tsum tau soj ntsuam raws li cov txheej txheem tshwj xeeb.
Helium
Helium zoo heev rau kev siv vuam uas muaj zog ntau, xws li vuam tooj liab thiab tooj liab sib xyaw. Nws cov thermal conductivity siab ua rau nkag mus tob dua, kov yeej qhov kev cov nyom uas tooj liab kub heev.
kev yaj tawm, thaum tseem txo qhov sib txawv ntawm qhov vuam oxidation. Vim nws tus nqi siab, helium feem ntau yog tseg rau cov ntawv thov tshwj xeeb, muaj kev thov ntau.
Kev Huv Si thiab Kev Ceev Faj
Kev Huv ntawm Cov Roj: Siv cov roj uas huv heev (≥ 99.99%) kom ntseeg tau tias kev vuam ruaj khov thiab qhov zoo ntawm kev vuam. Txawm tias cov khoom tsis huv me me kuj tuaj yeem ua rau muaj qhov tsis zoo xws li qhov porosity thiab tawg.
Cov Pa Roj Txwv Tsis Pub Siv: Yuav tsum tsis txhob siv cov pa roj sib xyaw, cov pa roj carbon dioxide, thiab cov pa oxygen, vim tias lawv tuaj yeem ua rau cov hlau vuam oxidation, ua rau cov porosity ntau ntxiv, thiab txawm tias ua rau lub cev kho qhov muag puas tsuaj.
Xaus lus:
Kev xaiv thiab siv cov roj tiv thaiv kom raug tsis yog tsuas yog ua kom zoo dua xwb4 hauv 1 lub tshuab laser vuamtsos thiab lub zog tab sis kuj txo cov nqi kho thiab ua kom lub neej khoom siv ntev dua. Nws yog ib qho tseem ceeb hauv kev ua kom ntseeg tau tias
kev ua haujlwm laserwelding zoo, ruaj khov.
