Kauv yeeb nkab yog dav siv nyob rau hauv cov roj av, roj av, tshuaj lom neeg kev lag luam, fais fab kev lag luam, cua sov kev lag luam, dej mov thiab tso dej kev lag luam, chav cua sov, hydropower siab steel yeeb nkab, thermal zog, dej thiab lwm yam ntev-nyob deb kis tau tus mob pipeline thiab piling, dredging, txuas hniav, steelstructure thiab lwm yam haujlwm.

Hauv kev siv thiab tsim cov txheej txheem ntawm kauv steel yeeb nkab, tib neeg tau tsim ntau txoj kev vuam zoo thiab cov txheej txheem ntau lawm, thiab pab txhawb kev txhim kho thiab nrawm ntawm qhov kev lag luam no, tab sis kuj ua rau kev lag luam zoo hauv kev txhim kho.Tsis siv neeg submerged arc vuam yog ib txoj kev vuam tshiab tsim nyob rau hauv 1940, thiab nyob rau hauv pem hauv ntej ntawm phau ntawv welding nws los yog slag tiv thaiv, tab sis qhov seem no tsis yog cov electrode txheej yog melting tawm ntawm vuam flux.Mus rau hauv lub cuab yeej xaim xa hlau thiab xaim teb rov qab, yog li cov hlau txuas ntxiv rau cov xaim hluav taws xob, yog li cov hlau sib txuas thiab evaporation los ua kab noj hniav, lub arc ntawm ruaj khov combustion nyob rau hauv kab noj hniav nyob rau hauv, yog li hu nws tsis siv neeg submerged arc vuam.Lub arc yog faus rau hauv ib kab noj hniav hauv.Lub tsho tiv no muaj ib lub funnel uas muaj cov welding flux thauj los ntawm cov yeeb nkab yuav tsum tau welded nyob rau hauv pem hauv ntej ntawm ob qhov sib txawv yog tias siv electrodes, hlau, vim hais tias hlau yuav muab nruam;electrode, peb hlawv ib tug electrode yuav tsum muaj ib tug muab ib tug electrode taub hau pov, thiab kev khiav hauj lwm kom nres, hloov lub electrode ua ntej welding.

Xws li txoj kev vuam piv nrog rau lwm txoj hauv kev yog qhov zoo ntawm cov kav dej kauv, thawj qhov zoo: kom paub txog qhov automation;Qhov thib ob kom zoo dua, uas yog submerged arc nyob rau hauv vuam, tshav kub pauv thiab kev tiv thaiv kev ua tau zoo kuj muaj zog, qhov vuam zoo kuj yog siab;Qhov thib peb zoo dua, vim tsis siv neeg submerged arc vuam arc faus hauv qab lub tsho, yog li nws tuaj yeem siv cov vuam tam sim no ua haujlwm siab.
