Thaum vuam cov hlau tsis xeb, kev xaiv electrode yog qhov tseem ceeb rau kev ua tiav qhov vuam zoo thiab ruaj khov. Qhov no yog qhov uasAF2209-15 (AWS E2209-15)los rau hauv. Lub electrode stainless hlau duplex uas muaj cov pa roj carbon tsawg heev no yog tsim los ua kom tau raws li qhov xav tau vuam tshaj plaws. Nrog nws cov txheej hydrogen tsawg, AF2209-15 ua kom muaj kev vuam zoo thiab kev ua tau zoo.
AF2209-15 yog tsim los rau kev vuam cov hlau tsis xeb duplex thiab muaj kev tiv thaiv xeb zoo heev thiab muaj zog siab. Nws cov pa roj carbon tsawg heev txo qhov kev pheej hmoo ntawm carbide precipitation, ua kom ntseeg tau tias cov khoom siv kho tshuab zoo heev thiab weldability. Cov ntsiab lus nitrogen ntxiv txhim kho qhov tsis kam ntawm qhov vuam rau pitting thiab crevice corrosion, ua rau AF2209-15 zoo tagnrho rau cov ntawv thov tseem ceeb hauv kev lag luam xws li roj thiab roj av, kev ua tshuaj lom neeg thiab kev tsim kho hauv hiav txwv.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm AF2209-15 yog nws cov txheej txheem hydrogen tsawg, uas txo qhov kev pheej hmoo ntawm hydrogen-induced cracking. Qhov no ua rau nws haum rau kev siv vuam qhov twg hydrogen embrittlement yog qhov txhawj xeeb, xyuas kom meej tias muaj kev ncaj ncees thiab lub neej ntev ntawm lub vuam. Lub electrode lub arc ruaj khov thiab cov yam ntxwv vuam du ntxiv pab txhawb rau nws yooj yim siv thiab kev ua haujlwm tas li, ua rau muaj kev ua haujlwm vuam zoo, txhim khu kev qha.
Ntxiv rau qhov kev ua tau zoo heev ntawm kev vuam, AF2209-15 yog tsim los nrog kev ua tau ntau yam thiab yooj yim hauv siab. Txawm siv rau qhov chaw tiaj tus, kab rov tav, ntsug lossis saum toj kawg nkaus, cov electrode no muab cov vuam zoo sib xws thiab zoo. Nws yog qhov tsim nyog rau ntau yam khoom siv hauv paus, suav nrog UNS S31803, S32205 thiab S2205 duplex stainless hlau, ua rau nws yog qhov kev daws teeb meem ntau yam rau ntau yam kev siv vuam.
Zuag qhia tag nrho, AF2209-15 teeb tsa tus qauv tshiab rau cov hlau tsis xeb vuam electrodes, xa cov kev ua tau zoo tsis sib xws, kev ntseeg siab thiab kev hloov pauv tau yooj yim. Muaj cov pa roj carbon nitrogen tsawg heev, cov txheej hydrogen tsawg thiab kev tiv thaiv corrosion zoo dua, cov electrode no yog qhov kev xaiv zoo tshaj plaws rau kev vuam zoo dua thiab kev ua haujlwm ntev. Txawm hais tias koj ua haujlwm rau cov haujlwm tseem ceeb lossis cov ntawv thov kev tsim kho vaj tse, AF2209-15 yog qhov kev daws teeb meem rau cov teeb meem vuam nyuaj tshaj plaws.
