Nkag siab txog qhov tseem ceeb ntawm kev ua kom tsim nyog cov yeeb nkab vuam cov txheej txheem rau kauv cov yeeb nkab siv hauv cov dej hauv av
Muab Kauv Hlau Kavtau siv dav hauv cov kav dej hauv av vim lawv lub zog siab thiab muaj peev xwm tiv thaiv sab nraud sab nraud. Cov kav dej yog tsim los ntawm kub-rolled steel coil strips uas ua ib tug kauv duab. Cov txheej txheem vuam siv los tsim cov kav pipes no muab cov qauv kev ncaj ncees zoo tshaj plaws, ua rau lawv zoo tshaj rau cov ntawv thov hauv av.

Ib qho tseem ceeb tshaj plaws ntawm kev siv kauv steelYeeb nkab rau cov dej hauv avyog tsim kom tsim tau cov txheej txheem vuam. Vuam yog tus txheej txheem ntawm koom nrog ob qho hlau los ntawm kev thov kub thiab siab. Rau cov kav dej hauv av, vuam zoo ncaj qha cuam tshuam rau tag nrho cov raj xa hluav taws xob thiab kev ntseeg tau ntawm cov raj xa dej.
Raws caiYeeb Nkab Wrding Cov Txheej TxheemRau kauv steel yeeb muaj ntau cov kauj ruam tseem ceeb. Ua ntej, cov nplaim hluav taws yuav tsum welded yuav tsum tau welded yuav tsum huv thiab tsis muaj paug ntawm tej kev paug xws li av, roj, lossis pleev xim. Qhov no ua kom pom tseeb tias cov weld yog muaj zog thiab tsis muaj kev cuam tshuam uas tuaj yeem ua rau muaj zog.
Tom ntej no, vuam qhov tsis zoo xws li cov tswv yim cua sov, vuam ceev, thiab cov txheej txheem yuav tsum ua kom tiav cov khoom siv zoo. Siv cov ntaub ntawv vuam kom zoo thiab cov tswv yim yog qhov txwv tsis pub muaj qhov tsis xws luag, kab nrib pleb, lossis tsis muaj kev sib luag, kev ncaj ncees ntawm Weld.
Ib qho ntxiv, ua kom zoo preheating thiab tom qab Weld Kev Kho Mob Thaum Tshav Kub Kub yog qhov tseem ceeb rau cov kab mob kauv siv hauv cov dej hauv av. Preheating pab txo txoj kev pheej hmoo ntawm kev tawg thiab txhim kho tag nrho Weld Zoo, thaum ua kom muaj kev nyuaj siab thaum tshaj tawm kev ntxhov siab thaum muaj kev nyuaj siab thoob plaws hauv thaj chaw Weld.
Tsis tas li ntawd, kev siv cov tshuab siab tshaj lij xws li siv cov txheej txheem vuam thiab tsis yog kev ua kom muaj kev sim siab ntxiv txhim kho kom zoo thiab kev ntseeg tau ntawm vuam. Cov thev naus laus zis pab kom ntseeg tau tias welded pob qij txha ua tau lub zog thiab cov qauv zoo los muab kev thaj yeeb nyab xeeb txog kev ua haujlwm hauv av ntev.
Hauv cov ntsiab lus, cov yeeb nkab kom tsim nyog vuam yog qhov tseem ceeb los ua kom muaj kev ncaj ncees thiab kev muab cov kauv cov yeeb nkab siv tau cov kab hauv av. Los ntawm kev ua raws li kev xaiv vuam tsim nyog, cov txuj ci thiab kev pheej hmoo ntawm kev sib tw vuam tsis xws luag thiab ua tsis tiav tuaj yeem txo qis. Qhov tshwm sim yog ib txoj kab ntseeg tau thiab ruaj khov uas tuaj yeem tiv taus lub sijhawm ntsuas thiab muab cov kev pabcuam nyab xeeb thiab muaj kev nyab xeeb thiab muaj kev nyab xeeb thiab muaj kev nyab xeeb thiab muaj kev nyab xeeb thiab muaj kev nyab xeeb thiab muaj kev nyab xeeb thiab muaj kev nyab xeeb rau kev pabcuam dej nyab xeeb thiab muaj kev nyab xeeb. Rau cov dej hauv av hauv av, nqis peev pab rau cov chaw tsim vuam yog ib kauj ruam tseem ceeb hauv kev ntseeg tau qhov kev ntseeg siab tag nrho thiab ntev ntawm cov raj xa dej.
