Lub kauv steel yeeb nkab yog kauv seam steel yeeb nkab raws li cov hlau yob phaj raws li cov khoom siv raw, uas feem ntau yog nyem thiab tsim, thiab welded nrog tsis siv neeg dual-wire ob-sided arc vuam txheej txheem.
faus arc tsis siv neeg vuam yog ib txoj kev vuam tshiab tsim nyob rau hauv 1940. Nws yog tib yam li nws yog tib yam li yav dhau los tes-welding, tab sis nws siv cov khoom seem tiv thaiv. Txawm li cas los xij, cov residue no tsis yog ib ntsiav tshuaj uas yog welded thiab yog cov tshuaj vuam tshwj xeeb uas yaj.
Txoj kev vuam ntawm cov kauv steel yeeb nkab yog tshwj xeeb tshwj xeeb. Cov yam ntxwv yog: siv cov cuab yeej squeezing los nyem lub puab nto ntawm sab hauv ntawm cov hlau phaj ntawm ob sab ntawm cov welded seams unsaturated, tshem tawm cov ntsiab lus tseem ceeb ntawm qhov tsis sib xws. welded.
Nyob rau tib lub sijhawm, cov cuab yeej squeezing kuj yog siv los ua cov cuab yeej tso rau vuam taub hau. Lub taub hau vuam yog yuav tsum nruj nreem kaw nrog lub tshuab extrusion. Thaum cov cuab yeej squeezing txav raws lub welded seam, nws tau ua kom ntseeg tau tias lub vuam taub hau kuj raug raws li lub taub hau vuam. Unde -welded vuam txav txav los xyuas kom meej tias lub taub hau vuam yog ib txwm nyob hauv nruab nrab ntawm qhov vuam. Qhov no tuaj yeem ua kom ntseeg tau tias qhov zoo ntawm cov vuam seam yog txiav welded thiab qhov zoo ntawm cov kab ntau lawm yog ruaj khov thiab zoo heev, thiab nws yog qhov yooj yim tsis muaj phau ntawv kho.
Thawj qhov kom zoo dua ntawm txoj kev vuam ntawm kauv steel kav yog tias thawj qhov zoo dua yog kev paub txog automation; Qhov thib ob kom zoo dua yog weld nyob rau hauv faus arc, yog li nws cov thermal txauv thiab kev tiv thaiv kev ua tau zoo kuj muaj zog, thiab qhov zoo ntawm vuam yog muab piv nrog kev sib piv zoo. Siab; Qhov thib peb kom zoo dua yog tias lub arc yog faus nyob rau hauv cov tshuaj vuam vim hais tias lub arc tsis siv neeg vuam yog txiav welded.
Lub kauv steel yeeb nkab yog kauv seam steel yeeb nkab raws li cov hlau yob phaj raws li cov khoom siv raw, uas feem ntau yog nyem thiab tsim, thiab welded nrog tsis siv neeg dual-wire ob-sided arc vuam txheej txheem.
Qhov txawv ntawm qhov tsis siv neeg arc tsis siv neeg vuam yog qhov tsis siv neeg arc tsis siv neeg vuam tsis siv lub tshuab electrode, thiab cov vuam hlau siv, vim tias cov vuam hlau tuaj yeem muab txuas ntxiv; cov kab txaij yuav tsum tau muab pov tseg tom qab cov nplaim taws ntawm lub thawv yuav tsum tau muab pov tseg, thiab kev ua haujlwm tsis ua haujlwm. , Hloov cov sawb thiab ces welded. Tom qab hloov nws mus rau vuam hlau, siv lub cuab yeej thiab welded hlau ntawm vuam hlau mus txuas ntxiv muab nws mus rau welded hlau. Txoj kev welding no yog cov vuam xaim tsis tu ncua xa mus rau hauv. Ib feem ntawm cov melting thiab evaporation ntawm weld tsim ib kab noj hniav. Lub arc yog hlawv stably nyob rau hauv kab noj hniav, yog li nws yog hu ua faus arc tsis siv neeg vuam.
