Fabrication thiab vuam yog cov kauj ruam tseem ceeb hauv kev tig A588 Qib A Corten Steel rau hauv cov khoom siv tau siv tau-los ntawm facades mus rau cov qauv teeb. Ntau tus neeg tsim khoom thiab cov neeg yuav khoom xav paub: Puas yog qib Corten no yooj yim ua haujlwm nrog? Nws puas xav tau cov cuab yeej tshwj xeeb lossis kev txawj ntse rau kev txiav, khoov, lossis vuam? Vuam puas yuav cuam tshuam nws cov kev tiv thaiv corrosion? Lub ntsiab lus teb yog qhov tseeb:A588 Qib A Corten Steel yog ib qho yooj yim rau kev tsim thiab vuam nrog cov cuab yeej txheem - nws lub zog sib npaug thiab kev ua kom yooj 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: Yooj yim nrog cov cuab yeej txheem
A588 Qib A qhov muaj pes tsawg leeg (tus qauv los ntawm ASTM A588) ua rau nws yooj yim txaus rau cov txheej txheem fabrication, tsis muaj cov cuab yeej tshwj xeeb yuav tsum tau:
Txiav: Yooj yim txiav nrog plasma txiav, oxy- roj txiav, lossis txawm tias siab - nrawm nrawm- ua haujlwm ib yam li cov pa roj carbon zoo tib yam, nrog cov npoo huv, du uas yuav tsum tau ua tiav tsawg kawg.
Khoov & sib sau: Nws qhov nruab nrab ductility tso cai rau khoov thiab shaping yam tsis muaj cracking, txawm rau me ntsis nkhaus (zoo tagnrho rau cov khoom dai los yog kev cai thav duab). Tsis xav tau ua ntej- cua sov rau cov phaj Tsawg dua lossis sib npaug li 20mm tuab.
Drilling & Punching: Drills thiab xuas nrig ntaus los ntawm yooj yim nrog cov cuab yeej txheem, ua kom yooj yim ntxiv qhov rau fasteners lossis sib dhos- tseem ceeb rau kev tsim vaj tsev thiab vaj tse.
Vuam: Ncaj nraim nrog kev ceev faj tsawg
Vuam A588 Qib A tsis yooj yim dua li vuam cov hlau zoo tib yam, tsuas yog ob peb kauj ruam tseem ceeb los tswj nws qhov kev ua tau zoo:
Tau tshaj Vuam Txoj Kev: Ua haujlwm nrog txhua yam kev siv vuam sib txuas-MIG, TIG, thiab arc vuam (SMAW)- siv tus qauv, Corten- sib xws electrodes (xws li, E7018) kom phim nws cov muaj pes tsawg leeg.
Preheating: Tsis tshua xav tau: Rau cov phaj Tsawg dua los yog sib npaug ntawm 20mm tuab (feem ntau yog rau fabrication), tsis tas yuav tsum tau preheating. Tsuas yog daim hlau ＞ 20mm tuab lossis vuam nyob rau hauv huab cua txias (＜10℃/ 50℉) yuav tsum tau preheating tsawg (60-100 degree).
Tshaj tawm - Weld Care: Cia welds txias lawm (tsis muaj kev yuam kom txias) kom tsis txhob muaj kev ntxhov siab. Lub patina yuav tsim nyob rau hauv lub weld cheeb tsam nyob rau lub sij hawm, tswj corrosion kuj -tsis muaj kev kho mob ntxiv.
Tswv yim tswv yim rau kev yooj yim Fabrication & Vuam
Cov kauj ruam yooj yim no txuag lub sijhawm thiab ua kom zoo, txawm tias tsis tshua muaj kev paub txog fabricators:
Siv Corten- cov khoom siv vuam sib xws: Qhov no ua kom cov welds phim cov hlau tiv thaiv corrosion, tiv thaiv xeb ntawm qhov sib koom ua ke.
Tsis txhob overheating thaum dabtsi yog khoov: Khaws qhov kub thiab txias kom tsis txhob ua rau cov hlau tsis muaj zog lossis ua rau nws lub peev xwm ua kom muaj kev tiv thaiv patina.
Ntxuav qhov chaw ua ntej welding: Tshem tawm cov av, roj, los yog xeb xoob kom ntseeg tau tias muaj zog, huv welds-qhov no kuj pab cov patina sib npaug tom qab.
Common Myth Debunked
Lus dab neeg: Corten Steel yog ib qho nyuaj rau weld thiab fabricate.Qhov tseeb: A588 Qib A yog tsim los rau kev yooj yim ntawm fabrication- nws ductility thiab compatibility nrog cov qauv txheej txheem ua rau nws siv tau rau feem ntau fabricators, tsis muaj tshwj xeeb kev kawm yuav tsum tau.
Hauv luv luv, A588 Qib A Corten Steel yog ib qho yooj yim rau fabricate thiab weld. Nws ua haujlwm nrog cov cuab yeej txheem thiab cov txheej txheem vuam, yuav tsum tau ceev faj tsawg, thiab tswj hwm nws qhov kev ua tau zoo tshaj -fabrication- ua rau nws xaiv qhov zoo rau cov fabricators thiab buyers ib yam nkaus.
