Koj puas tuaj yeem Mig Weld nrog cov tshuaj Co. tsuas yog?

Mig vuam, muaj nuj nqis rau nws txoj kev ua tau zoo thiab kev yoog raws kev tiv thaiv cov roj av los tiv thaiv lub weld pas dej paug ntawm cov pa taws ntawm covmos. Ib lo lus nug uas nquag muaj nyob hauv kev lag luam yog seb puas yuav siv tau cov pa roj ntshiab yog siv rau cov vuam mig. Cov lus teb yog muaj, tab sis tsuas yog raws li cov xwm txheej - Tseem muaj thaum vuam carbon hlau los yog qis {{{{}} cov hlau alleoy. Lub ntsej muag dawb yog tus nqi -} Qhov kev xaiv ua tau zoo thiab tsim nyog rau cov khoom siv uas tsis yog} {{precision appss.
Vim Li Cas Ciaj Ua Haujlwm Rau Cov Khoom Siv Hluav Taws Xob Mig Vuam
Carbon Steel thiab tsawg {{{- alloy steel (nrog 0.25% carbon) zoo}}}}}}}}}}}}}}}}
Siv zog tiv thaiv kev tiv thaiv kev sib kis
Kev sib xyaw ua pa oxygen thiab nitrogen nyob rau hauv thaj chaw weld, tiv thaiv kev tsim ntawm brittle oxides lossis nitrides hauv cov hlau molten. Thaum cool yog cov roj rhib (nws cuam tshuam rau hauv cov pa thiab cov pa roj carbon monoxide nyob rau hauv cov pa roj carbon monoxide Cov xov hlau muab tub lim rau kev sib xyaw ua ke rau kev sib xyaw ua ke xws li er70
Txhim kho kom nkag rau cov ntaub ntawv tuab
Cov ntshiab ntawm cov khoom kub ua rau muaj qhov kub tshaj, muaj kev tsom xam ntau dua li Argon - Raws li. Qhov kev tawm tswv yim tshav kub no txhim kho kev nkag mus, ua rau nws zoo tagnrho rau vuam tuab carbon (1/4 nti los yog tuab dua) lossis pob qij txha nrog cov khoob khoob. Nyob rau hauv cov txheej txheem txheej txheem -} qhov twg sib sib zog yog qhov tseem ceeb rau cov qauv kev ua tiav {}}} yuav tsum tau nkag mus rau hauv cov pob qij txha tseem ceeb.
Tus nqi efficiency rau high - nplej ua hauj lwm
CO₂ yog qhov pheej yig dua li Argon lossis Argon -} }₂} koom nrog rau 50% qis rau ib qho cubic ko taw. Rau qhov loj- Cov phiaj xwm cov haujlwm - Xws li tsim kho lub cim ntsuas tsheb lossis cov choj tsim kho} Qhov no txhais tau tias txuag tau nyiaj ntau. Nws cov pheej yig, sib xyaw ua ke nrog nws cov txiaj ntsig ntawm cov hlau, tau ua kom muaj cov ntshiab yeem ua rau muaj kev lag luam mig vuam.
Txwv: Thaum dawb huv CO₂ poob luv luv
Thaum ua tau zoo rau cov hlau carbon, ntshiab yog tsis yog kev daws teeb meem thoob ntiaj teb. Nws cov drawbacks txwv nws siv hauv ntau qhov xwm txheej:
Kev ua tau zoo ntawm tsis - ferrous hlau
Aluminium, hlau stainless, thiab tooj liab tsis tuaj yeem welded nrog cov ntshiab kam. Txhuas cov ntaub ntawv ntom ntom oxide txheej uas co₂ oxidation me oxidation exacerbates, tiv thaiv kom zoo fusion. Stainless hlau welded nrog co₂ poob chromium (ib qho tseem ceeb rau corrosion tsis kam) rau oxidation, tawm hauv weld nquag muaj xeb. Rau cov ntaub ntawv no, inert gases zoo li argon yuav tsum tau tswj tshuaj lom neeg.
Nce hluav taws xob ntxiv thiab weld tsos tsos
Qhov kub tshaj plaws arc los ntawm kev ua kom muaj ntau yam ua rau muaj ntau lub luag Qhov no yuav tsum tau txuas ntxiv ntxiv - Weld tu, uas yog impractical rau pom welds (piv txwv li cov khoom siv ua haujlwm) lossis cov khoom siv ua ntej qhov chaw ua tiav. Argon - be₂ tov (piv txwv li, 75% tsim cov duab nqus tsev ntxhua khaub ncaws, ua rau lawv nyiam dua rau kev ua kom zoo nkauj lossis qis} spatative applications.
Kev pheej hmoo ntawm brittleness hauv high - cov hlau carbon
High -} cov pa roj carbon (nrog ntau dua 0.3% carbon) welded nrog cov ntshiab carbon los ntawm cov roj ntau dhau, brittic qauv zoo li martensite. Qhov no nce qhov kev pheej hmoo ntawm post - Weld cracking, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig txias. Rau cov ntaub ntawv no, argon - reated freaks (piv txwv li 90% ntawm) txo cov pa roj carbon, txuag kev ua haujlwm.
Kev coj ua zoo tshaj plaws rau MIG VUAM Nrog Cov Dawb Huv
Txhawm rau ua kom pom tseeb thaum siv cov ntshiab koom rau cov roj hlau MIG VUAM:
Phim cov tub lim hlau rau cov roj
Siv cov xaim desexidized zoo li ER70S-6, uas muaj silicon (0.8-115%) thiab manganese (1.4-1.85%) kom tiv thaiv cov txiaj ntsig oxidizing. Zam cov xov hlau dav dav, uas tsis muaj cov tshuaj ntxiv thiab yuav tsim tau porous lossis welds welds.
Txhim Kho Roj Flow Cov Nqi
Tswj tus nqi txaus ntawm 20-30 CFH (cubic feet ib teev). Tsawg dhau ib qho ntws tawm ntawm qhov chaw weld raug rau huab cua, ua rau muaj qhov dav; Cov dej khib nyiab ntau dhau thiab tsim cov cua hlob uas rub tawm hauv cov paug tsis huv. Rau cov hlau tuab (1/2 nti lossis ntau dua), nce ntws mus rau 25-30 cfh los tiv thaiv cov pas dej weld loj dua.
Kho cov ntawv vuam vuam
Lub ntsej muag dawb huv yuav tsum muaj cov voltage me ntsis ntau dua li sib cav sib ceg kom ruaj khov arc. Ib qho kev teeb tsa rau 0.035 - nti hlau ntawm 1/4 volts yog 22-24 volts nrog ib tug hlau pub ceev ntawm 300-350 nti ib feeb. Tham nrog cov neeg siv xua xaim hluav taws xob cov lus qhia rau cov khoom siv tshwj xeeb.
Kev tswj yuam kev proction
Siv anti {- nti sppays los yog lub taub hau huv si burter - weld tu. Rau cov ntawv thov uas pom muaj teeb meem, xav txog li 80%
Cov ntawv thov zoo tagnrho rau cov ntshiab yeem mig vuam
Ntshiab Coos zoo txuj ci zoo hauv cov xwm txheej ua ntej tus nqi, nkag mus, thiab Carbon Steel sib xws:
• Txheej txheem steelrice: vuam kuv {{{{mi} Be} Beams, thiab cov tsiaj muaj zog, ua kom muaj zog, ua raws li kev sib koom ua ke.
• Kev kho kom hnyav: kho cov thoob cov hlau tuab (piv txwv li, cov tsheb nrau av lossis crane qhov muaj peev xwm ua kom tiav cov fustom lossis thaj chaw puas.
• Cov khoom lag luam: High- ntim ntau lawm kab rau kev siv vuam zoo li cov nqaj hlau, levelaging nws qhov ceev thiab tus nqi.
• Ua teb vuam: Hauv kev mob sab nraum zoov lossis yeeb ncuab sib txawv (siab dua li tawm tsam cua, txo qhov kev pheej hmoo ntawm cov roj sib xyaw.

Cov ntshiab? Nws lub peev xwm los muab cov kev tiv thaiv txaus, txhim kho kev nkag mus, thiab txo cov nqi ua rau nws tsis tseem ceeb hauv kev muaj chaw muaj kev muaj chaw. Thaum nws yog qhov tsis haum rau tsis - cov ntaub ntawv thov siab, nws lub luag haujlwm hauv cov vuam muag khoom lag luam tseem tsis tau txais kev pheej hmoo thiab ua tau zoo.
Los ntawm kev siv cov ntshiab kam nrog txoj cai ua kom xaim xaim thiab cov kab ke, txhim khu kev qha cov pa roj carbon monoxide
