Vuam yog ib kauj ruam tseem ceeb hauv kev tsim Corten Steel rau kev tsim vaj tsev, vaj tsev, thiab sab nraum zoov tej yaam num. ASTM A242 Hom 1 yog cov huab cua nrov, tab sis ntau tus neeg tsim khoom thiab cov neeg yuav khoom xav tsis thoob: Nws puas yooj yim rau vuam? Nws puas xav tau cov cuab yeej tshwj xeeb lossis kev txawj ntse? Yuav vuam cuam tshuam nws cov corrosion kuj lossis lub zog? Lub ntsiab lus teb yog qhov tseeb:Yog lawm, ASTM A242 Hom 1 Corten Steel tuaj yeem txuas tau yooj yim nrog cov cuab yeej txheem thiab cov txheej txheem- tsis muaj cov cuab yeej tshwj xeeb xav tau, tsuav yog ua raws li cov kev coj ua zoo tshaj plaws. Hauv qab no yog cov lus qhia yooj yim, cov tswv yim.
Vim li cas ASTM A242 Hom 1 Yog Weldable rau Feem ntau Fabricators
ASTM A242 Hom 1, tus qauv tsim los ntawm ASTM International, yog tsim los ua haujlwm tau - nws muaj pes tsawg leeg sib npaug corrosion kuj nrog weldability:
Alloy Balance: Thaum nws muaj tooj liab, chromium, thiab npib tsib xee rau kev tiv thaiv corrosion, cov hlau no ntxiv rau hauv cov nqi tswj uas tsis cuam tshuam kev vuam. Tsis zoo li siab - alloy steels, nws tsis xav tau cov txheej txheem tshwj xeeb.
Compatibility nrog Standard Vuam txoj kev: Nws welds tau yooj yim nrog cov tswv yim sib xws-MIG, TIG, thiab shielded hlau arc vuam (SMAW, los yog nplaum vuam)- tib txoj kev siv rau cov pa roj carbon zoo tib yam.
Tsis Muaj Preheating (feem ntau): Rau cov phaj Tsawg dua los yog sib npaug li 20mm tuab (qhov ntau tshaj plaws rau kev ua haujlwm sab nraum zoov / cov qauv), tsis xav tau preheating - txuag lub sijhawm thiab kev ua haujlwm rau fabricators.
Tswv yim Vuam Tswv Yim rau ASTM A242 Hom 1
Ua raws li cov kauj ruam yooj yim no, tus nqi - ua haujlwm tau zoo los xyuas kom yooj yim, muaj zog, thiab corrosion- tiv taus welds:
Xaiv Txoj Cai Electrode/Filler: Siv Corten-tshaj electrodes (piv txwv li, E7018 rau SMAW, ER70S-6 rau MIG) kom phim cov hlau alloy muaj pes tsawg leeg-qhov no tswj kev tiv thaiv corrosion ntawm qhov sib koom ua ke.
Ntxuav thaj chaw Weld: Tshem tawm cov xeb, av, roj, lossis oxide ntawm qhov sib koom ua ntej vuam. Qhov no tiv thaiv impurities hauv weld thiab ua kom muaj kev sib raug zoo.
Tswj Weld Thaum tshav kub kub: Siv cov khoom siv hluav taws xob nruab nrab- zam kom tsis txhob muaj cua sov, uas tuaj yeem ua rau cov hlau tsis muaj zog lossis ua rau nws lub peev xwm ua kom muaj kev tiv thaiv patina. Kev ruaj khov, qeeb weld pace ua haujlwm zoo tshaj plaws.
Tshaj tawm - Weld Care: Cia lub weld txias lawm (tsis txhob yuam kom txias zoo li cov tshuaj tsuag dej) los tiv thaiv cov kab nrib pleb. Tsis muaj kev tshaj tawm -weld heat treatment yog xav tau rau feem ntau cov haujlwm.
Thaum Vuam yuav xav tau kev saib xyuas ntxiv
Thaum nws yooj yim rau vuam hauv feem ntau, ua tib zoo ceev faj me me rau cov xwm txheej no:
Phaj tuab (＞ 20mm): Preheat rau 60–100℃(140–212℉) txhawm rau tiv thaiv kom txias sai thiab tawg yooj yim - siv lub tshuab hluav taws xob propane lossis hluav taws xob cua sov pam rau cov cua sov sib xws.
Txias Welding Conditions: Yog tias vuam nyob rau hauv qhov kub qis dua 10℃(50 ℉), preheat qhov chaw nyob ib ncig ntawm lub vuam kom tsis txhob brittleness nyob rau hauv qhov sib koom ua ke.
Siab -Stress Welds: Rau cov txheej txheem welds tseem ceeb (piv txwv li, cov khoom siv choj), siv cov khoom siv hluav taws xob qis me ntsis thiab xyuas kom tag nrho cov weld nkag mus rau qhov siab tshaj plaws.
Common Welding Myth Debunked
Lus dab neeg: Corten Steel yog ib qho nyuaj rau vuam thiab yuav tsum muaj kev txawj tshwj xeeb.Qhov tseeb: ASTM A242 Hom 1 welds yooj yim li cov pa roj carbon zoo tib yam -txhua tus fabricator nrog cov kev paub vuam yooj yim tuaj yeem ua haujlwm nrog nws, siv cov cuab yeej txheem.
Hauv luv luv, ASTM A242 Hom 1 Corten Steel yog ib qho yooj yim rau vuam rau feem ntau fabricators. Nrog cov cuab yeej txheem, sib xws electrodes, thiab cov kev coj ua zoo tshaj plaws, koj tuaj yeem ua tiav qhov muaj zog, corrosion-tiv taus welds- ua rau nws xaiv qhov zoo tshaj plaws rau txhua hom welded tej yaam num.
