Vim lubqis carbon steelyog nrog cov ntsiab lus carbon tsawg, manganese, silicon cov ntsiab lus tseem me me, yog li ntawd, nyob rau hauv ib txwm muaj xwm txheej yuav tsis raug welded los tsim cov ntaub so ntswg hnyav lossis quenched qauv.Tsawg carbon steel welding pob qij txha plasticity thiab qhov cuam tshuam zoo toughness, vuam, thiab feem ntau tsis tas yuav tsum tau preheating tswj txheej kub thiab tom qab kub, tsis muaj tom qab vuam kub kho los txhim kho lub koom haum thiab tag nrho cov txheej txheem vuam tsis tas yuav tsum tau tshwj xeeb. ntsuas nyob rau hauv tus txheej txheem, zoo heev weldability.

Txawm li cas los xij, nyob rau hauv ob peb kis, welding kuj nyuaj:
(1) Kev tsim cov hlau hloov pauv cov txheej txheem qub smelting nrog cov ntsiab lus nitrogen siab, cov ntsiab lus impurity, txias brittleness, nce rhiab heev rau kev laus, txo qhov zoo ntawm cov pob qij txha welded, vuam deteriorate.
(2) boiling steel deoxidation tsis tiav cov pa oxygen ntau dua, P impurities xws li kev faib tsis sib luag ntawm cov ntsiab lus hauv zos yuav dhau mus, kev laus rhiab heev thiab txias brittleness rhiab heev ntawm kub cracking nyiam nce.
(3) Qhov zoo tsis ua raws li qhov yuav tsum tau ua ntawm cov electrodes, yog li cov pa roj carbon monoxide hauv cov hlau, cov ntsiab lus sulfur siab dhau, tuaj yeem ua rau tawg.Q235-A steel acid electrode vuam, xws li lub Hoobkas, vim tias cov electrode npog ferromanganese siab carbon cov ntsiab lus, yuav ua rau weld kub tawg.
(4) Qee txoj kev vuam yuav txo qhov zoo ntawm cov pob qij txha welded ntawm cov hlau tsis tshua muaj carbon.Xws li electroslag vuam kab zog, ua kom ntxhib grained cheeb tsam ntawm lub tshav kub cuam tshuam cheeb tsam grain zoo nkaus li loj heev ua rau ib tug loj poob rau hauv tej yam toughness tom qab vuam yuav tsum normalized nplej refinement los txhim kho tej yam toughness.

Nyob rau hauv luv luv, tsawg-carbon steel yog nrog weldability zoo tshaj plaws thiab feem ntau yooj yim welded, tag nrho cov vuam txoj kev yog siv rau ib tug tsawg-carbon steel welding.
