Hauv kauv cevntau lawm txheej txheem thiab kev siv, muaj invented ib tug ntau ntawm zoo heev welding thiab cov txheej txheem ntawm ntau lawm, zoo heev pab mus rau lub ruaj khov thiab ceev txoj kev loj hlob ntawm kev lag luam, tab sis kuj ua rau qhov kev lag luam no tau optimized nyob rau hauv txoj kev loj hlob.Qhov twg submerged arc vuam yog ib txoj kev vuam nyob rau hauv ib tug tshiab invention nyob rau hauv 1940, nws thiab pem hauv ntej ntawm qhov chaw yog tib yam phau ntawv vuam los yog siv cov slag los tiv thaiv nws, tab sis qhov no tsis yog lub slag electrode txheej, yog tsim smelting flux tawm. .Hloov tom qab cov xaim, cov xaim xaim xaim nrog lub phaj thiab cov xaim, cov xaim xaim tsis tu ncua, qhov vuam hlau no tau noj tsis tu ncua hauv cov ntaub ntawv fusible flux npog ignition arc vuam hlau, cov khoom siv hauv paus thiab ib feem ntawm cov ntaub ntawv melting thiab evaporation flux. kab noj hniav, lub arc yog ruaj khov combustion nyob rau hauv cov kab noj hniav nyob rau hauv, yog li hu nws submerged arc vuam.Arc yog muab faus rau hauv qhov kab noj hniav.Lub vuam flux hopper loading system muaj cov tshuaj xa los ntawm cov yeeb nkab yuav tsum tau welded mus rau pem hauv ntej ntawm ob hom vuam yog siv, kev siv cov hlau, vim cov xaim tuaj yeem raug xa mus tas li;Qws, ib tug pas nrig uas peb yuav tsum muaj ib tug hlawv lub vuam taub hau muab pov, thiab lub lag luam raug nres, thiab ces hloov electrode welding.

Thiab xws li welding txoj kev piv nrog rau lwm txoj kev yog qhov zoo tshaj plaws, thawj qhov zoo dua yog siab automated;Qhov thib ob kom zoo dua, uas yog faus nyob rau hauv arc vuam, yog li nws yog lub tshav kub pauv thiab kev tiv thaiv ntawm kuj muaj zog kev ua tau zoo, zoo welding tawm;Qhov thib peb kom zoo dua, vim hais tias lub submerged arc vuam arc faus rau hauv lub flux, yog li nws yuav siv tau ib tug loj tam sim no, vuam efficiency kuj siab.
