Hauv kev vuam cov qauv thiab kev lag luam, kev xaiv cov ntaub ntawv sau kom haum yog qhov tseem ceeb rau kev ua kom muaj kev sib koom ua ke thiab kev ua tau zoo.Cov Hlau Carbon Vuam Electrodepawg yog qhov tseem ceeb, suav nrog ntau hom tsim los ua kom tau raws li cov kev cai tshwj xeeb thiab cov txheej txheem. Ntawm cov no, AWS E7015, kuj feem ntau hu ua qauv 507 hauv qee thaj tsam, sawv cev rau lub electrode qis-hydrogen siv dav rau cov ntawv thov carbon steel tseem ceeb.
Lub ntsiab lus tseem ceeb ntawm Carbon Steel Welding Electrode no yog nws cov txheej txheej sodium uas tsis muaj hydrogen ntau. Cov txheej txheej no yog qhov tseem ceeb rau kev txo qis kev nkag mus ntawm hydrogen rau hauv cov hlau vuam, uas txo qhov kev pheej hmoo ntawm kev tawg vim hydrogen, tshwj xeeb tshaj yog nyob rau hauv cov seem tuab dua lossis nyob rau hauv cov xwm txheej txwv. Cov hlau tso tawm qhia tau tias muaj kev hloov pauv zoo heev, kev tawv, thiab kev tiv thaiv kev tawg tag nrho, ua rau nws haum rau cov chaw nyuaj uas qhov kev ntseeg siab ntawm cov qauv tseem ceeb heev.
Los ntawm qhov kev xav ntawm kev ua haujlwm, qhov noCov Hlau Carbon Vuam Electrodeyuav tsum tau siv Direct Current Electrode Positive (DCEP) polarity. Cov yam ntxwv hluav taws xob no muab kev nkag mus tob thiab lub arc ruaj khov. Qhov tseem ceeb, lub electrode yog tsim los rau txhua qhov chaw vuam, muab kev hloov pauv rau kev siv tiaj tus, kab rov tav, ntsug, thiab saum toj. Qhov no ua rau nws yog ib qho cuab yeej muaj txiaj ntsig rau kev tsim khoom nyuaj thiab kev tsim kho thaj chaw uas qhov kev taw qhia vuam sib txawv.
Qhov kev siv rau lub tshuab vuam hlau carbon carbon no yog qhov tau piav qhia zoo. Nws yog qhov pom zoo rau kev vuam cov hlau carbon nruab nrab thiab qee cov qauv hlau uas tsis muaj hlau ntau. Cov ntaub ntawv siv feem ntau suav nrog cov qib xws li 09Mn2Si, Q345 (cov hlau sib npaug rau ASTM A572 Gr. 50 hauv Suav teb), thiab 09Mn2V. Nws cov yam ntxwv ua rau nws tsim nyog rau kev tsim khoom thiab kho hauv kev lag luam xws li kev tsim kho, kev tsim nkoj, kev tsim cov hlab siab, thiab cov tshuab hnyav dav dav uas qhov vuam yuav tsum phim lossis tshaj qhov tawv ntawm cov hlau.
Tus qauv AWS E7015 / J507 ua piv txwv txog cov khoom tseem ceeb hauvCov Hlau Carbon Vuam Electrodekev faib tawm. Nws cov txheej txheem hydrogen qis, ua ke nrog txhua qhov chaw muaj peev xwm siv DCEP, daws cov teeb meem feem ntau hauv kev vuam cov hlau uas yooj yim puas tsuaj. Los ntawm kev xa cov hlau uas muaj kev ncaj ncees siab, cov khoom siv kho tshuab zoo, thiab txo qhov kev tawg, lub electrode no muab cov kev daws teeb meem txhim khu kev qha rau cov kws tshaj lij ua haujlwm ntawm cov hlau carbon tseem ceeb thiab cov hlau sib txuas tsawg hauv ntau qhov kev lag luam.
