A588 Corten HlauYog siv dav hauv cov ntawv thov cov qauv thiab cov kws kos duab vim nws lub zog siab thiab qhov tshwj xeeb tsis kam mus rau cov atmospheric corrosion.
Txawm li cas los xij, vuamA588 Corten HlauYuav tsum tau saib xyuas tshwj xeeb kom ntseeg tau tias cov txheej txheem kev ncaj ncees thiab kev ua haujlwm corrosion ntawm cov khoom kawg.
Qhov tseem ceeb ntawm kev kho kom zoo, tsim nyog muab tub rog xaiv hlau, tshaj tawm, tshaj tawm {}}} Weld tu, thiab kev nkag siab ntau vuam cov nyom.
Preheating ua ntej vuam
Preheating yog qhov tshwj xeeb tshaj yog thaum vuamA588 Corten Hlauphaj nyob rau hauv cov nplooj tuab lossis thaum qhov chaw kub kub muaj tsawg.
Preheating pab tiv thaiv kev tawg txias thiab minimizes thermal thermal poob siab nyob rau hauv tshav kub {}}} bein cuam tshuam thaj chaw (Haz).
Rau cov ntaub ntawv tuab dua 1 nti, ib qho kev kub siab ntawm 100-200℃(212-392℃f) feem ntau pom zoo.
Cov cua sov niaj hnub thoob plaws hauv thaj chaw weld txo qhov kev pheej hmoo ntawm qhov tsis sib haum thiab micro - kab nrib pleb.
Vuam cov khoom siv thiab cov hlau ua haujlwm
Thaum vuamA588 Corten Hlau, Nws yog qhov tseem ceeb siv tau muaj peev xwm tsawg - ally ineloy carter metals uas txhawb nqa corrosion tsis kam thiab cov khoom siv neeg kho tshuab. Cov cuab yeej siv ua ke suav nrog:
- AWS E8018 {- w lossis e7018 (cov roj av hydrogen)
- Er80s - g (rau GMAW / MIG txheej txheem)
- Corten cov xov xwm tshwj xeeb (txuam nrog cov khaub ncaws huab cua)
- Kev siv cov hluav taws xob cov xov hlau hlau muab rau cov xov hlau tuaj yeem cuam tshuam rau kev tiv thaiv weld kev tiv thaiv, ua rau muaj xeb ntawm cov pob qij txha.
Vuam cov tswv yim thiab kev coj ua zoo tshaj plaws
A588 Corten HlauYuav muab welded siv cov txheej txheem feem ntau xws li SMAW, GMAW, FCAW, thiab GTAW.
Txawm li cas los xij, tsim nyog sib koom ua ke thiab kev npaj yog qhov tseem ceeb kom ntseeg tau tias muaj zog, ruaj khov Welds.
Rau multi -} PASS Welds, Interpass Qhov Kub Tswj Kub kuj tseem ceeb kom tsis txhob muaj kev qaug zog ua kom sov.
Thaum vuam sib dhos cov hlau cuav, xws li koom nrogA588 Corten HlauRau cov hlau me, cov kev txiav txim siab tshwj xeeb yuav tsum tau ua.
Nyob rau hauv cov rooj plaub no, corrosion tsis kam ntawm qhov sib koom ua ke yuav raug txo kom tsawg, yog li kev tiv thaiv txheej tiv thaiv lossis kev sib khi yuav tsim nyog.
Post - weld tu thiab kho mob
Tom qab vuam, lub cheeb tsam weld yuav tsum ntxuav kom huv, sib cais, thiab cov txheej txheem huab cua zoo los ua kom muaj kev sib txawv ntawm cov huab cua.
Yog hais tias tus qauv welded yog muab tso tseg tsis tau, kev tu kom zoo kom lub xeb patina muaj tusyees dhau sijhawm.
Hauv qee kis, tshaj tawm {- Weld Kev Kho Mob Kub (PWT) yuav ua, tshwj xeeb yog rau kev ntxhov siab tseem ceeb
thiab txhim kho txoj kev nruj nyob hauv weld cheeb tsam.
Cov Vuam Txoj Kev Sib Tw
Undermatching corrosion resistance:Tshwm sim los ntawm kev xaiv ua haujlwm tsis raug.
Nrib pleb hauv tshav kub -} be} cuam tshuam cheeb tsam (Haz):Feem ntau vim tsis txaus siab preheating.
Xim mismatch lossis patina inconstency:Los ntawm cov kab mob tsis sib xws los yog cov txheej txheem sib txawv welding.
