Kauv yeeb nkab yog ib tug kauv seam welded yeeb nkab ua los ntawm sawb hlau kauj raws li raw khoom, extruded ntawm qhov kub thiab txias, thiab welded los ntawm tsis siv neeg ob-xaim ob-sided submerged arc vuam txheej txheem.

Txoj kev vuam ntawm submerged arc tsis siv neeg vuam yog tib yam li phau ntawv vuam nyob rau hauv uas nws tseem siv cov slag tiv thaiv, tab sis cov slag no tsis yog txheej ntawm cov electrode, tab sis cov vuam flux tshwj xeeb smelted.

Cov yam ntxwv ntawm txoj kev vuam ntawm cov kav hlau yog: siv cov cuab yeej extrusion ua ntej nyem lub puab txheej ntawm cov hlau phaj ntawm ob sab ntawm cov hlau tsis sib xws kom tshem tawm cov tsis sib xws thiab xyuas kom meej tias sab hauv ntawm cov hlau phaj ntawm ob sab. ntawm lub unwelded weld yog huv si thiab du, thiab ces welded.

Nyob rau tib lub sijhawm, cov cuab yeej extrusion kuj tseem siv los ua cov cuab yeej siv rau lub taub hau vuam, uas yog, lub taub hau vuam thiab cov cuab yeej extrusion yog nruj nreem tsau ua ke, thiab thaum lub tshuab extrusion txav raws qhov tsis muaj vuam, nws tau lees paub tias. Lub taub hau vuam kuj tseem raug raws li qhov tsis sib xws ntawm seam txav los xyuas kom meej tias lub taub hau vuam yog ib txwm nyob hauv nruab nrab ntawm cov seam. Nyob rau hauv txoj kev no, nws tuaj yeem ua kom ntseeg tau tias qhov zoo ntawm cov welds uas tsim los ntawm kev siv vuam tsis siv neeg ntawm cov kab ntau lawm yog qhov ruaj khov thiab zoo heev, thiab tsis tas yuav tsum tau kho cov ntawv kho.

Qhov no txoj kev ntawm welding kauv kav, thawj zaug, realizes automation; Thib ob, nws yog welded nyob rau hauv submerged arc, yog li nws cov kev sib hloov tshav kub thiab kev tiv thaiv kev ua tau zoo kuj muaj zog, thiab qhov zoo ntawm vuam yog kuj siab; Thib peb Qhov zoo dua yog vim qhov tseeb tias lub arc yog faus rau hauv qhov flux hauv submerged arc tsis siv neeg vuam.

Qhov sib txawv ntawm submerged arc tsis siv neeg vuam yog: submerged arc tsis siv neeg vuam tsis siv vuam rods, tab sis vuam hlau, vim tias cov vuam hlau tuaj yeem raug pub tsis tu ncua; vuam rods, peb yuav tsum muab pov tseg ib tug vuam pas nrig taub hau tom qab hlawv ib tug vuam pas nrig, thiab lub lag luam yuav tsum tau nres. Hloov lub vuam pas nrig thiab vuam dua. Tom qab hloov mus rau vuam hlau, vuam hlau pub khoom siv thiab vuam hlau reel yuav txuas ntxiv pub cov vuam hlau. Txoj kev vuam no yog ua kom tsis tu ncua pub cov vuam hlau thiab hlawv cov arc nyob rau hauv lub hau ntawm lub meltable granular flux kom cov vuam hlau thiab lub hauv paus hlau Ib feem ntawm lub melting thiab evaporation ntawm cov flux tsim ib kab noj hniav, thiab cov arc burns stably nyob rau hauv lub welding. kab noj hniav, yog li nws yog hu ua submerged arc tsis siv neeg vuam.
