Kauv steel yeeb nkabthiab cov txheej txheem ntau lawm, tib neeg tau tsim ntau yam zoo heev vuam thiab ntau lawm txoj kev, thiab zoo heev txhawb kev ruaj khov thiab ceev txoj kev loj hlob ntawm kev lag luam, kuj ua rau qhov kev lag luam hauv kev txhim kho optimized.Tsis siv neeg submerged arc vuam yog ib txoj kev vuam tshiab, tsim nyob rau hauv 1940, nws yog tib qhov chaw thiab pem hauv ntej ntawm phau ntawv vuam yog nws los yog slag tiv thaiv, tab sis qhov seem no tsis yog electrode txheej, vuam tshuaj tshwj xeeb smelting.Nyob rau hauv cov hlau, nrog rau cov txhais tau tias thiab cov hlau reel xa cov vuam hlau, txuas ntxiv xa mus rau cov hlau, txoj kev vuam no yog ua kom tsis tu ncua pub cov hlau, arc ignited meltable particulate solder coverage ntawm cov hlau, thiab cov khoom siv hauv paus, thiab ib feem. ntawm lub melting thiab evaporation ntawm cov flux tsim ib kab noj hniav arc hauv cov kab noj hniav ruaj khov combustion, yog li hu nws tsis siv neeg submerged arc vuam.Lub arc yog faus rau hauv kab noj hniav.Vuam tshuaj system yog loaded los ntawm ib tug funnel welding tshuaj los ntawm ib tug yeeb nkab pub rau pem hauv ntej ntawm lub yuav tsum tau welded.Qhov sib txawv thib ob yog tsis siv electrodes, siv cov hlau, vim tias cov hlau tuaj yeem xa mus tas li;electrode, hlawv ib tug electrode yuav tsum muaj ib tug vuam pas nrig taub hau muab pov, thiab lub lag luam yog nres, lwm yam vuam pas nrig thiab ces welded.

Xws li vuam txoj kev piv nrog rau lwm txoj kev, muaj ib tug zoo kom zoo dua ntawm no welding submerged arc kauv yeeb nkab no txoj kev, ib tug thawj kom zoo dua yog tag nrho cov automated;Qhov thib ob kom zoo dua, nws yog nyob rau hauv lub faus arc nyob rau hauv vuam, yog li nws cov cua sov pauv thiab kev tiv thaiv kev ua tau zoo kuj muaj zog, kuj zoo vuam zoo;Qhov thib peb kom zoo dua, txij li qhov tsis siv neeg submerged arc vuam arc yog faus rau hauv qab ntawm cov tshuaj vuam, yog li nws tuaj yeem siv tau tam sim no loj, qhov vuam efficiency kuj siab.

Tsis tas li ntawd, cov spiral steel kub dov strip steel kauv dabtsi yog khoov, tsis siv neeg submerged arc vuam (tseem hu ua kauv steel yeeb nkab, kauv yeeb nkab) nyob rau hauv lub seam thiab sab seam welded kauv steel yeeb nkab.Vim yog cov laj thawj hauv qab no, nws tuaj yeem siv dav rau kev tsim cov kab loj loj kauv yeeb nkab:
1) hloov lub kaum sab xis, koj tuaj yeem siv tib qhov dav ntawm lub sawb kauv steel yeeb nkab ntau lawm calibres;
2) vim nws yog ib qho txuas txuas ntxiv, muab kauv steel yeeb nkab txiav ntev tsis txwv;
3) weld kauv sib npaug faib rau tag nrho cov kauv yeeb nkab ncig, qhov tseeb qhov tseeb ntawm cov kauv yeeb nkab yog siab, lub zog kuj siab;
4) yooj yim hloov qhov loj, haum rau me me ntawm cov kauv steel ntau lawm ntau yam.
