A588 Qib B Corten Steel tau txais kev pom zoo rau nws qhov kev txhim kho toughness thiab corrosion kuj, tshwj xeeb tshaj yog rau hnyav-lub luag haujlwm thiab txias- tej yaam num huab cua. Tab sis ntau tus neeg tsim khoom thiab cov neeg yuav khoom xav paub txog nws txoj haujlwm ua haujlwm: Puas yog qhov siab tshaj - qib Corten yooj yim rau vuam thiab fabricate? Nws puas xav tau cov cuab yeej tshwj xeeb lossis kev txawj ntse? Yuav vuam cuam tshuam nws lub zog lossis corrosion tsis kam? Lub ntsiab lus teb yog qhov tseeb:A588 Qib B Corten Steel yog ib qho yooj yim rau welding thiab fabricate nrog cov khoom txheem -nws qhov sib npaug ductility thiab compatibility nrog cov tswv yim ua rau nws siv tau, tsuas yog yuav tsum tau ceev faj me ntsis.. Hauv qab no yog cov lus qhia yooj yim, cov tswv yim.
Fabrication: Ncaj nraim nrog cov cuab yeej txheem
Raws li Corten Steel tus qauv tsim los ntawm ASTM A588, Qib B khaws cov khoom ua haujlwm zoo ib yam li lwm qib A588, yuav tsum tsis muaj cov khoom siv tshwj xeeb:
Txiav: Yooj yim txiav siv plasma txiav, oxy- roj txiav, lossis siab- nrawm nrawm- ib yam li cov pa roj carbon zoo tib yam. Nws tsim cov npoo huv uas xav tau kev ua tiav tsawg, txuag lub sijhawm ntawm kev tshaj tawm - txiav kev ua haujlwm.
Khoov & sib sau: Nws nruab nrab ductility tso cai rau du dabtsi yog khoov thiab shaping, txawm rau me ntsis nkhaus (zoo tagnrho rau cov qauv thav duab los yog kev cai Cheebtsam). Tsis xav tau ua ntej- cua sov rau cov phaj Tsawg dua lossis sib npaug li 20mm tuab, feem ntau thickness rau feem ntau cov haujlwm.
Drilling & Punching: Drills thiab xuas nrig ntaus los ntawm kev siv zog nrog cov cuab yeej txheem, ua kom yooj yim ntxiv qhov rau fasteners lossis sib dhos- tseem ceeb rau kev siv vaj tse thiab vaj tse.
Vuam: Yooj yim nrog kev ceev faj tsawg
Vuam A588 Qib B tsis yog qhov nyuaj tshaj qhov vuam zoo tib yam, tsuas yog ob peb kauj ruam tseem ceeb los khaws nws cov kev ua tau zoo:
Txoj kev vuam sib xws: Ua haujlwm seamlessly nrog txhua yam kev siv vuam-MIG, TIG, thiab arc vuam (SMAW). Siv Corten-tshaj electrodes (piv txwv li, E7018) kom phim nws cov alloy muaj pes tsawg leeg thiab xyuas kom corrosion kuj ntawm vuam.
Preheating: Tsis tshua muaj yuav tsum tau: Rau cov phaj Tsawg dua lossis sib npaug ntawm 20mm tuab, tsis tas yuav tsum tau ua kom sov. Tsuas yog daim hlau ＞ 20mm tuab los yog vuam nyob rau hauv qhov txias txias (＜10℃/ 50℉) yuav tsum tau preheating tsawg (60-100 degree) los tiv thaiv weld tawg.
Tshaj tawm - Weld Care: Cia welds txias lawm (tsis txhob yuam kom txias) kom tsis txhob muaj kev ntxhov siab sab hauv. Kev tiv thaiv patina yuav tsim nyob rau hauv qhov chaw weld nyob rau lub sij hawm, tswj cov hlau corrosion kuj - tsis tas yuav tsum tau kho ntxiv.
Cov tswv yim tseem ceeb rau kev vuam yooj yim & Fabrication
Cov kauj ruam yooj yim no pab cov neeg tsim khoom ntawm txhua qib kev txawj ua tiav cov txiaj ntsig zoo:
Ntxuav qhov chaw ua ntej: Tshem tawm cov av, roj, los yog xeb xeb ua ntej vuam / txiav kom ntseeg tau tias muaj zog, huv si thiab kev txiav du.
Tsis txhob overheating: Thaum lub sij hawm khoov los yog vuam, ua kom kub nruab nrab los tiv thaiv cov hlau tsis muaj zog los yog ua rau nws lub peev xwm los tsim cov patina tiv thaiv.
Siv Corten-cov khoom siv tshwj xeeb: Vuam electrodes lossis cov hlau muab tub lim tsim los rau Corten Steel kom cov welds phim lub hauv paus hlau lub zog thiab corrosion kuj.
Common Myth Debunked
Lus dab neeg: High-tooj hlau zoo li A588 Qib B yog qhov nyuaj rau vuam.Qhov tseeb: Qib B yog tsim los rau kev ua haujlwm tau zoo - nws cov ductility thiab compatibility nrog cov txheej txheem cov cuab yeej ua rau nws yooj yim rau vuam thiab fabricate li A588 Qib A lossis cov hlau zoo tib yam.
Hauv luv luv, A588 Qib B Corten Steel yog yooj yim rau vuam thiab fabricate. Nws ua haujlwm nrog cov cuab yeej siv thiab cov txheej txheem, yuav tsum tau ceev faj tsawg, thiab tswj hwm nws qhov kev ua tau zoo tshaj plaws -kev ua haujlwm - ua rau nws yog qhov kev xaiv zoo rau fabricators thiab buyers ib yam nkaus.
