Nyob rau hauv EGW, lub tshav kub ntawm lub vuam arc ua rau cov electrode thiab workpieces yaj thiab ntws mus rau hauv kab noj hniav ntawm qhov chaw welded. Cov hlau molten no solidifies los ntawm hauv qab mus, koom nrog cov khoom ua welded ua ke. Lub cheeb tsam weld yog tiv thaiv los ntawm atmospheric paug los ntawm ib tug cais shielding gas, los yog cov roj uas ua los ntawm disintegration ntawm ib tug flux-cored electrode hlau. Cov electrode yog coj mus rau hauv qhov chaw weld los ntawm ib qho khoom siv hluav taws xob siv hluav taws xob, zoo li ib qho siv hauv electroslag vuam, lossis lub taub hau txav. Thaum siv cov khoom siv coj los siv, lub pas dej welded yog tsim los ntawm cov hlau molten los ntawm cov khoom siv welded, electrode, thiab cov raj coj. Kev hloov pauv ntawm lub taub hau siv lub rooj sib dhos ntawm lub raj electrode uas txav mus rau sab saud thaum lub vuam tau muab tso, ua kom nws tsis txhob yaj.
Electrogas welding tuaj yeem siv rau feem ntau cov hlau, nrog rau cov pa roj carbon tsawg thiab nruab nrab, cov hlau tsis muaj zog siab, thiab qee cov hlau tsis muaj steel. quenched thiab tempered steels kuj tseem tuaj yeem welded los ntawm cov txheej txheem, yog tias siv cov cua sov kom zoo. Welds yuav tsum yog ntsug, sib txawv rau ob sab los ntawm qhov siab tshaj plaws ntawm 15 degrees. Feem ntau, lub workpiece yuav tsum yog tsawg kawg yog 10 hli (0.4 nyob rau hauv) tuab, thaum lub siab tshaj plaws thickness rau ib tug electrode yog kwv yees li 20 hli (0.8 nyob rau hauv). Ntxiv cov electrodes ua rau nws ua tau rau weld thicker workpieces. Qhov siab ntawm qhov vuam tsuas yog txwv los ntawm cov cuab yeej siv los nqa lub vuam taub hau-hauv dav dav, nws nyob ntawm 100 hli (4 hauv) txog 20 m (50 ft).
Zoo li lwm cov txheej txheem arc vuam, EGW xav kom tus neeg teb xov tooj hnav lub kaus mom hlau thiab hnav khaub ncaws kom zoo kom tsis txhob raug cov hlau molten thiab qhov ci vuam arc. Piv nrog rau lwm cov txheej txheem, muaj ntau cov hlau molten tam sim no thaum vuam, thiab qhov no ua rau muaj kev nyab xeeb ntxiv thiab phom sij. Txij li cov txheej txheem feem ntau ua tiav ntawm qhov siab loj, kev ua haujlwm thiab cov khoom siv yuav tsum tau ruaj ntseg zoo, thiab tus neeg teb xov tooj yuav tsum hnav cov hlua ruaj ntseg los tiv thaiv kev raug mob thaum lub caij nplooj zeeg.
