2205 duplex Stainless hlau (DSS 2205) tau siv dav hauv marine engineering, thiab siab vessels, thiab siab cov hlab ntsha vim nws lub zog tshwj xeeb muaj zog thiab corrosion tsis kam. Txawm li cas los xij, nws txoj kev xav tau vuam feem ntau yog cov kev sib tw hauv kev siv cov ntawv thov. Cov xovxwm no tso tawm cov lus tshawb fawb tshiab rau kev tawm cov ntaub ntawv siv vuam, cov tswv yim, thiab cov tswv yim rau 2205 dss.
Pom zoo vuam cov txheej txheem thiab cov khoom siv cov tub lim
Roj Tungsten Arc Vuam (GTaw)
Gtaw yog txoj kev nyiam vuam 2205 DSS, tshwj xeeb tshaj yog rau cov pob qij txha tseem xav tau cov khoom siv zoo.Er 2209 muab tub lim hlauYog pom zoo, raws li nws cov ntsiab lus npib npib tsib xee thiab nitrogen ruaj khov nyob rau hauv werd, ua kom muaj zog thiab tawm tsam rau kev ntxhov siab corrosion tawg (SCC). Kev tshawb fawb pom zoo tias GTaw tsim cov ntsiab lus Austenite siab dua hauv cov hau kev piv rau cov hau kev zoo li SMAWAS, txhim kho tag nrho cov kev ua tau zoo.
Gas Hlau Arc Vuam (Gmaw) thiab submerged Arc Vuam Vuam (pom)
Cov txheej txheem hluav taws xob loj no haum tuab-phaj-phaj-phaj vuam tab sis xav tau kev tswj nruj ntawmCov tswv yim tshav kub (0. 5-2.5 KJ / hli)Cov. Ntau dhau ntawm cov lus tawm thaum tshav kub ua kom sov nrawm nrawm, nce cov ntsiab lus ferrite thiab txo kev sib cais.
Hluav Taws Xob Txoov Vuam (EBW)
Rau cov txheej txheem tuab-walled (piv txwv li, cov hlab ntsha siab), eBW nrog cov roj ntsha siab thiab npib tsib xee hluav taws xob (piv txwv li cov pa thermates Ntxiv rau npib tsib xee them rau cov nitrogen poob, txhawb kev ua kom tiav kev tsim thiab kho kom haum weld theem sib piv nrog cov hlau.
Cov kev tsis sib haum xeeb thiab cov txheej txheem optimization
Tiv Thaiv Roj: Ntxiv cov nitrogen (piv txwv li, ar + 2% n₂) Boosts Austrogen ntau, ruaj khov Austenite thiab ua kom haum corrosion.
Thaum tshav kub kub tswj: Cov kub ntau dhau ua rau cov qoob loo ceem thiab muaj kev ntxhov siab. Pulsed tam sim no lossis post-weld kev daws teeb meem tuaj yeem ua kom haum microstructure.
Dissimilar hlau vuam: Thaum koom nrog 2205 mus rau 316L Austenitic steel, antent tig (aig) outperforms pa rau kev nkag mus tob nrog thiab siab dua cov khoom siv zoo dua.
Nto Kho Thiab Cov Nyuaj
2205 DSS Cov khoom pov thawj kev ua tsis zoo machinility, ua rau muaj kev ua kom siab roughness thaum lub sijhawm txiav. Kev kho mob hauv Weld zoo li tua peening lossis laser poob siab peening (lsp) txhim kho kev qaug zog qaug zog thiab corrosion tsis kam. Zam kev noj tshuaj sulphur hauv kev ua, raws li lawv thuam corrosion tiv taus txawm hais tias txhim kho machinability.
Kev Tshawb Fawb Yav Tom Ntej
Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog:
Corrosion-yaig tus cwj pwm ntawm welds nyob rau hauv cov kev lag luam siab zog marine siab;
Txhim kho cov khoom siv-lub xeev vuam (piv txwv li, kev sib txhuam ua kom do vuam, fw);
Ai-tsav parameter tswj rau vuam xaiv.
Tag
Zoo vuam ntawm 2205 duplex stainless hlau khawm rau cov khoom sib xyaw, cov tswv yim tshav kub, thiab cov txheej txheem siab heev. GTAW nrog ER 2209 muab tub lim, cov tshuaj tiv thaiv cov pa roj, thiab tswj cov thermal thermal yog cov tswv yim ua pov thawj. Kev nthuav tawm thev naus laus zis zoo li EBW thiab ATIG tau nthuav dav cov ntawv thov hauv kev lag luam hnyav thiab cov geometries hnyav.
