Yuav tsum tau thawb lossis rub cov xaim flux?

Thaum siv flux core hlau -}}}}} {{1} {{1} {{1} {{1} {1} {1} {1} {{1} {1} {1}- Tsis zoo li cov hlau ua hlau vuam (qhov twg thawb cov qauv hlau cov ntaub thaiv npog tshuab (ntawm cov cim flux) ua rau rub lub teeb rau cov ntawv thov feem ntau. Txoj hauv kev no ua ke nrog tus mob flux ua rau tiv thaiv cov kev tiv thaiv cov roj tiv thaiv, kom meej dua cov tshuaj nqus tsev ntxhua khaub ncaws, cov txiaj ntsig zoo sib xws, thiab ntau yam kev sib nqus, thiab cov txiaj ntsig zoo sib xws, thiab muaj txiaj ntsig zoo dua.
Vim li cas rub (rub cov txheej txheem) ua haujlwm zoo tshaj plaws rau flux corek
Flux Core Hlau Relies ntawm ob - mels page uas tiv thaiv cov tshuaj weld uas tiv thaiv oxidation vim nws txias. Rub lub Tawb -} Txawm hais tias "rub cov txheej txheem" ​​{} Txoj haujlwm ntawm lub teeb, nrog lub taub hau saum npoo Weld. Lub kaum sab xis no ua rau cov flux thiab sleag sib cuam tshuam nrog cov hlau molten:
• Kev tiv thaiv roj zoo dua: rub kom cov pa flux Thaum thawb, lub thawv qhia teeb ua lub pas dej, thiab cov roj tuaj yeem tawm ntawm cov pa roj av, tawm hauv cov hlau molygen thiab nitrogen - ua rau porosity (npuas) hauv Weld.
• Tswj cov nplais sutter: Cov qoob loo ntawm Weld tom qab lub pas dej weld thaum rub tawm cov khoom siv ntuj uas ntsaws ruaj ruaj uas ntsaws ruaj ruaj. Kev thawb tuaj yeem cuam tshuam cov txheej txheem no, ua rau cov neeg sib xyaw nrog cov hlau molten (ua rau suav) lossis daim ntawv tsis xwm yeem, tawm ntawm qhov chaw muaj xeb tuaj yeem txhim kho tom qab.
• Kev nkag mus tob tob: rub rub tawm rau lub ARC kom ua kom pom kub raws ntawm cov hlau hauv paus, ntau dua li ntawm cov hlau nws tus kheej. Qhov no tob tshaj tawm kev ua kom sov zog ua kom cov hlau weld fuses nrog lub hauv paus hlau- Qhov tseem ceeb rau cov hlau muaj zog, tshwj xeeb tshaj yog rau ntawm cov hlau thicker (1/8 nti thiab saum toj no).
• Txo cov ncauj lus: Cov txheej txheem rub cov arc ruaj khov thiab cov flux hlawv cov yaum kom muaj zog (flux nti (cov tee hlau me me). Thawb feem ntau tsim kev coj ua tsis ncaj ncees Arc, raws li lub teeb taub taw thawb los ntawm kev sib tw fluces, ua rau ntau qhov kev xav tau post- Weld tu.
Thaum thawb yuav tsim nyog (thiab nws cov kev txwv)
Thaum rub tau zoo rau feem ntau flux tseem ceeb uas thawb lub teeb yog qhov zoo tshaj {{}}} Offs:
• Cov khoom siv nyias (16 ntsuas lossis rub tawm): txo qis ntxiv los ntawm kev pheej hmoo ntawm cov hlau, txo qis kev pheej hmoo ntawm hlawv - los ntawm. Txawm li cas los xij, qhov no los ntawm tus nqi ntawm cov tiv thaiv tsis muaj zog tiv thaiv {welders yuav tsum txav sai sai rau txo cov roj dispersion thiab tej zaum tseem pom cov porosity me me.
• Kev nyuaj - rau {{1} {{- Lub raj hluav taws xob tau yooj yim vim kev ua kom lub cev. Thawb tso cai kom pom kev zoo dua ntawm kev sib koom ua ke, tab sis yuav tsum ua tib zoo saib kom tsis txhob muaj Slag suav nrog.
Txawm nyob hauv cov rooj plaub no, thawb yog kev hais kom muaj kev sib haum xeeb. Welders feem ntau kho lawv lub teeb lub teeb me me (mus rau 5-10 degree) thaum ntsuas cov hlau sib tw nrog kev thaiv cov ntaub qhwv hluav taws xob. Rau cov ntaub ntawv tseem ceeb ntawm cov khoom siv nyias nyias, hloov mus rau ib lub cheeb hauv cov hlau me me (piv txwv li, 0.030-nti hloov ntawm 0.035-nti) thiab ua raws li rub tawm muaj kev nyab xeeb dua.
Cov lus qhia tseem ceeb rau rub tawm flux core hlau
Txhawm rau tswv lub Loos Technique thiab tau txais cov txiaj ntsig zoo tshaj plaws:
• Lub kaum sab xis ua kom raug: tuav lub teeb kaum ntawm 10-15℃kaum sab xis los ntawm kev ua haujlwm saum npoo av, nrog lub hau taw qhia rov qab mus rau qhov ua tiav Weld. Qhov no ua kom pom tseeb tias lub arc nyob qis qis rau ntawm ntug kev hauv Weld.
• Ua kom muaj kev mus ncig ua si: Tshem qeeb qeeb, thiab txoj kev me me yuav overheat thiab sib tov nrog cov hlau molten; Sai sai, thiab nkag mus rau kev txom nyem. Taw rau qhov nrawm uas cia lub swb yeeb yam du, cov txheej du, uniform txheej qab tom weld.
• Saib txoj kab slag: yuav tsum yog txoj kev taug mus rau 1 / 4-1 / 2 nti tom qab lub pas dej weld. Yog tias nws ntes tau rau hauv pas dej, qeeb me ntsis kom cia flux hlawv. Yog tias nws lags dhau deb, ceev mus kom tsis txhob muaj undercutting (ib qho zawj ntawm Weld Ntug).
• Kho Hlau Pub thiab Voltage: Flux Corek yuav tsum ntau dua cov hlau kom hlawv flux kom zoo. Tham nrog cov xaim xaij tsim cov txheej txheem (piv txwv li, 2235 - NCAUJ Siab dhau, thiab arc ua tsis ruaj khov.
Vim li cas cov "thawb thiab rub" sib cav sib cav sib cav sib cav los ntawm cov hlau khoom
Siv Hlau Vuam (nrog cov thaiv hluav taws xob roj) feem ntau pom zoo thawb, raws li cov roj ntsha ua noj ua pas dej weld thiab muab kev tiv thaiv weld thiab muab kev thaiv cov weld. Tab sis flux Core corekuv hloov pauv lub zog hloov pauv lub zog tsis zoo los ntawm Flux, tsis yog sab nraud roj, yog li rub tawm cov kev thaiv uas tiv thaiv. Kev tsis meej pem ob txoj hauv kev yog qhov ua txhaum cai rau cov pib tshiab, tab sis nco ntsoov cov yuam sij no sib txawv kom ntau cov teeb meem weld zoo.
Xaus: rub kom zoo, thawb tsuas yog thaum tsim nyog
Rau flux corek xaim, rub (cov txheej txheem rub) yog qhov tseeb ntawm kev coj ua zoo. Nws ua kom tau pa roj, ua kom muaj kev sib sib zog nqus, thiab tsim cov ntaub ntawv tshuaj ntxuav huv nrog tsawg heev. Kev thawb yuav tsum tau tshwj tseg rau cov ntaub ntawv nyias nyias lossis cov chaw nruj, thiab txawm tias tom qab ntawd, nws yuav tsum tau ua tib zoo cov txheej txheem kom tsis txhob muaj qhov tsis txaus.
Txoj cai yooj yim tshaj plaws: Yog tias koj siv cov xaim hluav taws xob tseem ceeb, rub lub laj thawj yog tias koj muaj qhov tshwj xeeb los ntsuas ntawm cov porosity lossis suav nrog. Nrog kev xyaum, cov txheej txheem rub dhau los ua tus thib ob, thiab qhov sib txawv hauv Weld zoo ua rau nws siv zog ua haujlwm.
