Koj puas tuaj yeem Weld dist hlau nrog tus pas nrig npib tsib?

Cam khwb cia hlau, paub rau nws tus brittleness thiab cov pa roj carbon ntau, tau ntev cov kev sib tw hauv vuam. Txawm li cas los xij, kev lag luam kev ua lag luam thiab kev tshawb nrhiav kev tshawb fawb tau lees paub tias Vuam cam khwb cia uas tsis yog tsuas yog ua tau yooj yim tab sis kuj tseem muaj kev tsim kho tshiab hauv kev tsim kho niaj hnub no thiab kho tau.
Cov tub ntxhais yog vim li cas rau kev ua tau: cov khoom sib xyaw
Nickel Rods, tshwj xeeb yog cov neeg muaj cov ntsiab lus npib tsib xee (xws li eni {{}}}}} Kev phim cov kev xav tau ntawm cov hlau cam khwb cia. Cam khwb cia hlau muaj 2% {4 4}}}}}} paacy, carbon yog ib qho zoo li hlau cam khwb zoo li hlau cam khwb, uas tuaj yeem ua rau tawg.
Npib tsib xee, raws li Austenitic stabilizer, tuaj yeem tsim qhov qis - cov qauv roj carbon aus roj hauv Weld. Tus qauv no tsis yog tiv thaiv cov pa roj carbon hauv cov hlau cam tab sis kuj muaj kev pheej hmoo zoo, ua rau muaj kev pheej hmoo ntawm vuam thaiv cov kab xev. Ib qho ntxiv, cov kab nthuav dav coefficient ntawm Nickel yog ze rau qhov kev ntxhov siab uas tsis sib xws los ntawm kev ua kom txias dua thaum lub tshuab vuam, txuas ntxiv txhim kho lub vuam zoo.
Qhov zoo: Kev ntsuas kev ua haujlwm zoo thiab zoo
Piv nrog lwm txoj kev vuam (xws li oxyacetylene vuam nrog cam khwb cia hlau rau weld distrial hlau tau pom zoo.
Ua ntej, nws muaj qhov muaj zog yoog rau lub hauv paus hlau. Txawm hais tias nws yog grey cam khwb cia hlau, zas cam khwb cia hlau lossis mibe cam khwb cia vuam cuam tshuam, zam qee cov khoom siv vuam tsuas yog tsim nyog rau cov khoom siv cam khwb cia.
Thib ob, txoj kev vuam yog qhov yooj yim. Cov kab tsib npib tsib tuaj yeem welded los ntawm cov thaiv hlau arc vuam (smaw) {}
Thib peb, Weld muaj cov tshuab kho zoo tshaj plaws. Weld tsim los ntawm Nickel Rods muaj lub zog siab thiab muaj zog tiv thaiv thiab corrosion tsis kam, uas tuaj yeem ua kom tau cov kev xav tau ntawm cov khoom siv pov cov hlau feem ntau.
Cov ntsiab lus tseem ceeb rau kev vam meej vuam: Ua raws li cov txheej txheem
Txawm hais tias Vuam cam khwb cia hlau nrog Nickel Rods yog ua tau, nws yog ib qho tsim nyog kom txawj cov txheej txheem tseem ceeb kom ntseeg tau lub vuam nyhav:
• Pre6 -} kev npaj khoom kom tshem tawm cov roj, xeb thiab lwm yam tsis txaus ntseeg kom tsis txhob muaj qhov hws thiab suav nrog Weld. Rau cam khwb cia hlau ua haujlwm nrog cov tuab tuab lossis teeb meem loj, preheating kub yog feem ntau yog qhov kev pheej hmoo txias thiab txo qhov kev pheej hmoo ntawm cov kab nrib pleb.
• Vuam parameter tswj: Xaiv vuam tam sim no raws li lub cheeb ntawm tus pas dej Nickel thiab cov tuab ntawm lub workpiece. Loj heev tam sim no yuav ua rau overheating ntawm lub hauv paus hlau, nce lub melting ntawm cov hlau cam khwb cia, thiab ua rau cov tshuaj pleev xim ntau dhau; Tsawg dhau ib qho tam sim no yuav ua rau muaj kev sib nkag siab tsis zoo thiab tsis tiav.
• Ncej -} welding kho: tom qab vuam, nws raug nquahu kom ua kom txias txias. Lub workpiece tuaj yeem qhwv nrog daim ntaub Asbestos lossis muab tso rau hauv tshav kub-} insulating cov khoom siv kom tsis txhob txias sai vim kub txias. Rau cov khoom tseem ceeb, ntxhov siab nyem annealing tuaj yeem nqa (tuav ntawm {{4 4}}
Daim ntawv thov cov khoom siv: xyaum cov nqi hauv kev lag luam
Hauv kev kho cov tsav tsheb, nickel Qws vuam ntawm cov hlau pov cov hlau tau siv dav. Piv txwv li, hauv kev kho lub cav lub tsev kawm lub tog raj kheej lub tog raj, siv cov khoom siv hlau txuas ntxiv thiab ua haujlwm ntawm lub neej, uas yog kev lag luam ntau dua li hloov chaw tshiab.
Hauv kev tsim khoom lag luam, qee cov hlau cam khwb cia nrog cov qauv nyuaj feem ntau muaj kev xav tau kev xav tau thaum lub sijhawm ua haujlwm. Siv cov pas nrig npib tsib rau vuam tuaj yeem ua kom muaj kev ncaj ncees thiab kev ua haujlwm ntawm cov haujlwm, txhim kho cov khoom tsim nyog.
Xaus: Ib qho Kev Xaiv Kom Tau Txais Los Ntawm Tshuab
Txhawm rau suav, vuam cam khwb cia hlau nrog tus pas nrig npib tsib yog lub thev naus laus zis thiab txhim khu kev qha los ntawm cov kev coj ua loj. Nws qhov kev ua tau yog raws cov khoom siv tau ntawm Nickel thiab cov khoom siv pov tseg los ntawm nws cov kev ua haujlwm zoo thiab kev vuam zoo nkauj thiab zoo heev veel muag zoo.
Nrog rau kev nce qib txuas ntxiv ntawm kev siv tshuab vuam thiab kev txhim kho cov txheej txheem ntawm cov qauv vuam hlau, muab cov kev txhawb nqa zoo rau kev tsim khoom lag luam thiab kev lag luam kho.
