Submerged arc vuam hlau, raws li lub npe qhia, yog cov khoom siv vuam hlau siv hauv cov txheej txheem submerged arc vuam. Submerged arc welding yog ib txoj kev vuam uas siv hluav taws xob arc los yaj cov vuam hlau thiab cov hlau hauv paus, nrog flux txhaws qhov chaw hauv qab. Thaum lub sij hawm vuam txheej txheem, vuam hlau yog pub rau hauv arc cheeb tsam los ntawm ib tug nruam hlau feeder thiab melts nyob rau hauv lub kub kub ntawm lub arc, tsim ib tug weld nrog lub hauv paus hlau. Ib txhij, lub flux melts nyob rau hauv lub cua sov ntawm lub arc thiab npog lub weld nto, tiv thaiv lub weld thiab tiv thaiv tsis xws luag xws li porosity thiab slag inclusions.
