Nyob rau hauv cov nqe lus ntawm welding txheej txheem, welding txoj kev ntawm kauv welded yeeb nkab thiab ncaj seam steel yeeb nkab yog tib yam, tab sis ncaj seam welded yeeb nkab yuav inevitably muaj ntau T-zoo li tus welds, yog li qhov tshwm sim ntawm vuam tsis xws luag kuj zoo heev nce, thiab lub welding residue ntawm T-shaped weld Qhov kev ntxhov siab yog loj, thiab cov hlau weld feem ntau nyob rau hauv peb txoj kev ntxhov siab, uas ua rau muaj kev tawg.
Ntxiv mus, raws li cov kev cai ntawm submerged arc vuam, txhua qhov vuam yuav tsum muaj qhov pib arc thiab qhov chaw arc quenching, tab sis txhua qhov ncaj seam welded yeeb nkab tsis tuaj yeem ua tau raws li qhov xwm txheej no thaum vuam lub voj voog ncig, yog li yuav muaj cov ntsiab lus arc quenching ntawm lub arc quenching point. Ntau qhov vuam tsis raug.
