Nyob rau hauv kev lag luam vuam, 6013 thiab 7018 yog ob lub vuam vuam, txhua tus muaj cov khoom siv thiab cov ntawv thov kev thov thiab daim ntawv thov kev xaiv. Rau cov neeg ua haujlwm, nkag siab txog qhov sib txawv ntawm lawv yog qhov tseem ceeb los xaiv cov cuab yeej zoo.
Cov Khoom Siv Neeg Kho Tshuab Thiab Weld Lub Zog
Qhov kev txawj ntse tshaj plaws ntawm 6013 thiab 7018 yog lawv cov tshuab neeg kho tshuab, tshwj xeeb yog Weld lub zog. Tus "60 xyoo 60 xyoo 6013 txhais tau tias nws Weld hlau muaj lub zog tsawg kawg ntawm 60,000 psi (phaus ib square nti). Qhov muaj zog no yog txaus rau kev siv vuam vuam uas tsis cuam tshuam cov kabmob hnyav heev.
Hauv kev sib piv, tus "70" txhais tau tias nws weld hlau muaj qhov tsawg kawg tensile lub zog ntawm 70,000 psi. Lub zog zog ua 7018 ntau haum rau cov phiaj xwm vuam cov txheej txheem uas xav tau} Bearing muaj cov tuam tsev thiab kev tsim cov tshuab hnyav.
Vuam qws txheej thiab Arc Performance
Qhov txheej txheej ntawm lub vuam pas nrig muaj qhov cuam tshuam tseem ceeb rau kev ua yeeb yam ntawm ARC thiab muaj qhov sib txawv ntawm. 6013}} raws cov txheej. Cov txheej no ua rau nws tsim cov khoom muag muag thiab ruaj khov arc thaum vuam. Txawm hais tias ARC muaj kev tawg yuam kev, nws tuaj yeem yooj yim re- tsim, uas yog tus phooj ywg zoo rau cov welders. Tsis tas li ntawd, lub ntsej muag ua rau thaum lub sijhawm vuam yog me me thiab lub ntsej muag yooj yim kom tshem tawm, uas tuaj yeem txo cov ncej- weld tu ua haujlwm.
7018 siv qhov tsawg - hydrogen hlau hmoov txheej. Cov txheej no yog tsim los txo cov ntsiab lus hydrogen hauv weld, yog qhov ua kom muaj kev pheej hmoo ntawm hydrogen {} {}} lub zog welds. Txawm li cas los xij, nws Arc yog qhov nyuaj thiab yuav tsum muaj kev txawj siab los tswj. Cov Welder xav tau kev tswj kom ntev ntev thaum lub sijhawm ua haujlwm, txwv tsis pub nws yooj yim los tsim tej yam tsis xws li pores. Tsis tas li ntawd, lub slag ntawm 7018 yog ntau viscous thiab tsis yooj yim tshem tawm raws li 6013.
Daim Ntawv Thov Kev Pab Cuam
Vim muaj cov yam ntxwv sib txawv, daim ntawv thov cov xwm txheej ntawm 6013 thiab 7018 kuj sib txawv heev {{{{} {rounder "hauv kev vuam niaj hnub. Nws yog dav siv nyob rau hauv daim ntawv kho qauv hlau, xws li kev kho ntawm lub cev tsheb hlau. Nws tseem haum rau kev tsim cov khoom siv lub teeb hlau, xws li cov thaib hlau thiab hlau nkhaus. Vim nws txoj kev ua haujlwm zoo, feem ntau nws siv nyob rau hauv kev cob qhia vuam los pab cov tswv yim tshiab vuam kev txawj.
7018 yog ntau zoo li ib tug "kws tshaj lij" hauv high -}} Thov vuam. Nws yog tsuas yog siv rau cov qauv tseem ceeb vuam. Piv txwv li, hauv kev tsim kho choj, 7018 yuav tsum siv rau kev siv vuam tseem ceeb rau kev nyab xeeb thiab kev ruaj ntseg ntawm tus choj. Nyob rau hauv siab txog nkoj tsim, tus weld xav tau wreaking siab, thiab lub siab heev muaj lub zog ntawm 7018 tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Pre6 - vuam thiab post -}} vuam
The pre-welding and post-welding treatment requirements of 6013 and 7018 also reflect their differences. 6013 has relatively low requirements on the surface of the parent material. Txawm hais tias muaj ib qho me me ntawm xeb, roj lossis lwm yam impurities nyob rau saum npoo, nws tuaj yeem welded ib txwm tsis nruj ua ntej-}} tu. Qhov no muaj peev xwm txuag tau lub sijhawm ua haujlwm ntau nyob rau hauv kev kho thaum muaj xwm ceev.
7018 tau ua nruj me ntsis rau ntawm cov khoom siv niam txiv. Ib qho impurities, xws li roj, xeb thiab noo noo, tuaj yeem ua rau muaj qhov tsis xws luag. Yog li, cov niam txiv cov khoom yuav tsum tau huv si ua ntej vuam. Ntxiv rau, 7018 yog rhiab rau ya raws. Yog tias khaws cia rau hauv ib puag ncig noo, txheej yuav nqus noo noo, uas yuav ua rau cov ntsiab lus hydrogen hauv Weld thiab ua rau tawg. Yog li ntawd, 7018 feem ntau yuav tsum tau khaws cia rau hauv lub thawv qhuav, thiab yog tias nws tsis damp, nws yuav tsum qhuav ua ntej siv. Rau qee qhov vuam ib qho tseem ceeb vuam cov phiaj xwm, tshaj tawm - Weld Weld kev kho mob kuj yuav tsum tau tshem tawm cov kev ntxhov siab vuam.
Hauv cov ntsiab lus, 6013 thiab 7018 txhua tus muaj txiaj ntsig thiab kho kom haum rau kev siv vuam thiab muaj peev xwm tsim nyog ua haujlwm thiab yog cov khoom siv zoo tshaj plaws rau cov qauv tseem ceeb vuam. Welders tuaj yeem xaiv cov kab hlau tsim nyog raws li cov kev xav tau ntawm txoj haujlwm los xyuas kom meej thiab nyab xeeb ntawm Weld.
