Cov hlau me me, paub txog nws cov ntsiab lus muaj peev xwm hauv vuam hlau, kev tsim khoom siv rau hauv vuam hlau xws li 304. Kuv puas tuaj yeem weld cov hlau me me nrog 308? Cov lus teb luv yog yog, tab sis nws los nrog caveats. Cia peb tshawb nrhiav cov ntsiab lus kom pab koj ua qhov kev txiav txim siab paub.
Cov yam ntxwv ntawm 308 vuam hlau thiab hlau me
308 vuam hlau yog ib qho kev ua kom tus neeg siv hluav taws xob tsis sib xws nrog cov chromium (ncig}%), npib tsib}}}}}}}}}}}}}}}}}}%), thiab cov roj carbon tsawg. Qhov no muab cov khoom sib xyaw no muab nws zoo corrosion tsis kam, siab dua cov khoom siv, ua rau nws zoo rau kev koom nrog stainless hlau uas yuav tsum tau ua tau zoo sib xws.
Cov hlau me me, ntawm qhov tod tes, yog cov pa hlau nrog cov ntsiab lus carbon tsawg dua 0.25%. Nws muaj qhov zoo weldability, tus nqi tsawg, thiab lub zog nruab nrab, tab sis nws tsis muaj lub corrosion tsis kam ntawm stainless hlau. Nws lub vuam feem ntau yog kev tso siab rau cov hlau me me hlau (xws li wr70s}) uas phim nws muaj pes tsawg leeg, ua kom muaj kev sib xyaw ua ke ntawm metallurgy thiab cov khoom siv tshuab.
Vim li cas 308 tuaj yeem thaiv cov hlau me me
Metallurgically, 308 tuaj yeem tsim cov kev sib koom tes nrog cov hlau me me. Thaum lub arc melts lub 308 xaim thiab cov hlau me me hlau hlau, cov molten pas dej sib xyaw, thiab tom qab solidification ua ke yog tsim. Lub npib tsib xee thiab chromium nyob rau hauv 308 tuaj yeem yaj mus rau hauv weld hlau, thiab ntev npaum li cov vuam tsis raug tswj hwm, kev sib koom tes tuaj yeem ua tiav ib qho kev ua kom muaj zog.
Hais txog kev ua haujlwm zoo, 308 ua haujlwm nrog cov txheej txheem mig uas muaj rau cov hlau me me. Nws tuaj yeem tswj cov arc ruaj khov nyob rau hauv qhov uas tsim nyog tam sim no thiab voltage chaw, thiab cov xaim pub mis yog qhov tseeb, tso cai rau kev ua haujlwm vuam.
Cov kev txwv thiab cov teeb meem muaj peev xwm
Thaum 308 muaj peev xwm weld cov hlau me me, muaj cov kev txwv me me. Ib qho ntawm cov teeb meem tseem ceeb yog kev tsis sib xws hauv cov khoom siv neeg kho tshuab. Cov hlau me me muaj lub zog qis dua piv rau kev siv hluav taws xob hauv Weld ua ke, tshwj xeeb ntawm kev siv nyiaj sib xyaws, tshwj xeeb yog cov kev siv tshuaj sib raug zoo.
Corrosion tsis kam yog lwm qhov kev txhawj xeeb. Txawm hais tias 308 muaj cov zoo corrosion tsis kam, thaum welded rau cov hlau me, hlau me me nws tus kheej tseem yog tus muaj xeb. Lub weld sib koom ua ke, uas yog kev sib xyaw ntawm ob cov ntaub ntawv, tej zaum yuav tsis ua tiav cov hlau corrosion, ua rau nws tsis haum rau cov av noo, tshuaj lom neeg, lossis ntsev pov tseg.
Tus nqi yog qhov tseem ceeb . 308} vuam hlau yog ntau dua kim dua cov hlau me me. Siv 308 rau weld cov khoom siv me me tsis tsim nyog, uas tsis yig rau loj- nplai {{4 4}} rwb cov ntawv thov.
Tsis tas li ntawd, cov xim ntawm cov weld tuaj yeem tsis sib xws nrog hlau me. Lub stainless hlau - nplua nuj weld hlau yuav muaj kev tsaus ntuj lossis txawv txav ntawm cov ntawv thov uas pom teeb meem.
Cov lus pom zoo rau cov xwm txheej tshwj xeeb
Kev kho tus kheej ib ntus: yog tias koj tsis muaj cov hlau tswj kev sib koom ua ke ntawm tes ntawm tes), 308 tuaj yeem siv los ua kev daws teeb meem ib ntus. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias qhov no tsuas yog luv luv-} kev kho kom haum, thiab kho kom raug nrog cov tub rog sib txuam yuav tsum tau ua tom qab.
Tsis - tseem ceeb, tsis xav tau cov kab mob hnyav, thiab tsis muaj kev sib cav, tab sis nws tseem tsis tau xaiv qhov zoo.
Zam hauv cov ntawv thov tseem ceeb: Load - Cov Khaub Ncaws Hnav (xws li cov tsheb ciav hlau sab nraum zoov), thiab cov phiaj xwm dej sab nraud yuav tsum tsis txhob siv 308 rau weld cov hlau me me. Hloov chaw, siv cov hlau sib txuas hlau me me uas phim cov khoom siv hauv paus.
Vuam cov lus qhia yog tias siv 308 ntawm cov me me hlau
Yog tias koj yuav tsum siv 308 rau weld me hlau me me hauv cov xwm txheej tshwj xeeb, ua raws cov lus qhia no. Siv cov tswv yim tshav kub qis los ntawm kev txo lub vuam tam sim no thiab hluav taws xob tsim nyog los txo qhov loj ntawm lub haz. Qhov no yuav pab txo txoj kev pheej hmoo ntawm cov nplej kev loj hlob hauv cov hlau me me loj hauv cov khoom siv, uas tsis muaj zog ntawm cov khoom siv.
Tswj cov kev mus ncig ua si. Kev mus ncig ua si sib tw ua kom pom tseeb qhov kev fusion txaus ntawm 308 xaim thiab hlau me tsis muaj overheating lub hauv paus hlau. Zam txhob txav qeeb dhau, vim qhov no tuaj yeem ua rau muaj melting ntau dhau thiab ua suab nrov.
Ntxuav lub hauv paus hlau kom huv si ua ntej vuam. Tshem cov xeb, roj, xim, thiab lwm yam paug los ntawm thaj chaw vuam los tiv thaiv porosity thiab suav nrog ntau dua kev sib koom tes.
Tom qab vuam, xav txog post -} Weld kev kho mob. Piv txwv li, kev sib tsoo weld mus rau ib tug du tag tuaj yeem txo kev ntxhov siab. Yog tias corrosion tsis kam yog xav me ntsis, siv anti - xeb part, suav nrog cov hlau me me, suav nrog cov xeb me me, kom qeeb qeeb.
Zoo dua lwm txoj hauv kev rau 308 rau cov hlau me
Qhov kev xaiv zoo tshaj plaws rau kev sib tw me me hlau yog cov hlau sib cav sib ceg. ER70s - 6 yog ib qho kev xaiv dav. Nws phim cov khoom muaj pes tsawg leeg thiab cov kws kho mob me me ntawm cov hlau me me, ua kom muaj zog, ductile weld sib koom nrog zoo fusion. Nws tseem raug nqi -} Ua tau zoo thiab haum rau feem ntau cov ntaub ntawv vuam cov hlau me me.
Rau tuab me hlau lossis thaum muaj zog dua yog xav tau, er80s- d2 tuaj yeem siv tau. Nws muaj lub zog ntau dua li ER70s- 6}}}} bearing} Cov kev tswj hwm kev sib haum xeeb nrog cov hlau me me.
Hauv cov ntsiab lus, thaum nws yog cov thev naus laus zis rau kev siv hluav taws xob zoo li cov teeb meem zoo li cov teeb meem zoo li cov teeb meem zoo li cov teeb meem zoo li cov teeb meem zoo li cov cuab yeej zoo li cov khoom siv xws li, thiab txwv corrosion tsawg. Rau kev ua tau zoo tshaj plaws, ib txwm siv cov muab tub lim hlau uas phim cov me me hlau uas tau txiav txim siab siv sijhawm thaum muaj xwm txheej lossis tsis yog} kev txwv, thiab paub txog nws cov kev txwv. Los ntawm kev xaiv cov tub rog sab xis hlau, koj tuaj yeem ntseeg tau qhov zoo, durability, thiab kev khwv nyiaj txiag ntawm koj cov hlau me me welds.
