Lub EM12K, ua raws li AWS A5.17 specification, sawv cev rau qib tshwj xeeb ntawmsubmerged arc vuam hlauTsim los rau kev sib txuas ntawm cov khoom siv carbon steel. Raws li qhov tseem ceeb tshaj plaws hauv cov txheej txheem vuam submerged arc, nws qhov kev ua tau zoo yog txuas nrog kev siv cov flux sib xws tib lub sijhawm. Cov hlau vuam submerged arc no yog tsim los tsim cov khoom sib txuas ruaj khov, muaj kev sib txuas siab uas muaj peev xwm tiv taus kev ntxhov siab ua haujlwm loj hauv cov chaw ua haujlwm nyuaj.
Ib qho yam ntxwv ntawm EM12K submerged arc welding wire yog nws cov tshuaj lom neeg sib xyaw ua ke. Cov hlau no muaj cov pa roj carbon ntau dua piv rau lwm cov qib hauv nws pawg. Nws yog alloyed nrog cov feem pua ntawm manganese thiab silicon, tsim tshwj xeeb kom dhau cov qib pom hauv EL12 hlau qib. Qhov sib npaug ntawm cov ntsiab lus no yog qhov tseem ceeb rau kev ua tiav cov khoom siv kho tshuab thiab tus cwj pwm metallurgical xav tau hauv qhov vuam tiav.
Qhov kev nce ntxiv ntawm manganese thiab silicon hauv cov hlau vuam no ua rau nws muaj peev xwm deoxidizing thaum lub sijhawm vuam. Qhov no yog ib qho tseem ceeb ntawm kev siv tshuab, vim nws tiv thaiv kev tsim cov porosity los ntawm kev khawb cov pa oxygen los ntawm cov pas dej vuam molten. Kev siv qhov nosubmerged arc vuam hlautxhawb nqa kev ruaj khov thiab kev ncaj ncees ntawm cov hlau vuam, ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov ntawv thov uas yuav tsum tau muaj kev sib xyaw zoo meej thiab tsis muaj qhov tsis xws luag.
Cov hlau vuam uas tau los ntawm cov hlau EM12K qhia txog qhov sib npaug zoo ntawm lub zog thiab kev ywj pheej, tsim nyog rau ntau txoj kev vuam. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov qauv hnyav, cov hlab ntsha siab, cov nkoj, thiab cov khoom siv uas raug kev thauj khoom siab. Nws qhov kev ua tau zoo tas li ua kom ntseeg tau tias cov pob qij txha vuam tseem ua tau zoo mus ntev, txawm tias nyob rau hauv cov xwm txheej kev pabcuam nyuaj uas cuam tshuam nrog kev co lossis kev ntxhov siab.
EM12Ksubmerged arc vuam hlauyog ib qho khoom siv tshwj xeeb uas tsim los rau cov ntawv thov carbon steel tseem ceeb. Nws cov tshuaj lom neeg sib txawv, uas muaj cov pa roj carbon, manganese, thiab silicon ntau dua, muab cov deoxidation zoo dua thiab cov khoom siv kho tshuab txhim khu kev qha hauv qhov xwm txheej as-welded. Kev ua raws li tus qauv AWS A5.17 lees paub nws qhov zoo sib xws, tsim kom muaj cov hlau no ua cov kev daws teeb meem zoo rau cov lag luam uas xav tau kev sib txuas ruaj khov thiab ua haujlwm tau zoo.
