Thaum lub sij hawm welding txheej txheem, welders tuaj yeem pom ib txheej ntawm cov ntaub ntawv uas ntab rau saum npoo ntawm lub pas dej molten, uas feem ntau hu ua vuam slag. Yuav ua li cas paub qhov txawv vuam slag los ntawm cov hlau molten yog ib qho tseem ceeb heev rau cov pib tshiab. Kuv xav tias nws yuav tsum paub qhov txawv ntawm qhov no.
Ua ntej, vuam slag yog cov khoom ntawm melting ntawm electrode txheej thiab kub-kub metallurgical cov tshuaj tiv thaiv ntawm cov vuam. Vuam slag feem ntau yog tsim los ntawm cov hlau oxides lossis cov hlau tsis yog hlau oxides thiab lwm cov ntxhia ntsev. Txij li thaum nws qhov ntom ntom me dua li ntawm cov kua hlau thaum lub sij hawm vuam, cov welder tuaj yeem yooj yim saib cov txheej txheem ntawm cov khoom siv ntab saum toj ntawm lub pas dej molten thaum lub sij hawm vuam txheej txheem. Nyob rau hauv cov nqe lus ntawm cov xim, nws yog tsaus dua li cov kua hlau nyob rau hauv lub molten pas dej ua ke, thiab ntws nyob rau hauv lub opposite kev taw qhia ntawm welding kev taw qhia thiab nyob rau ob sab ntawm lub rear, thiab txias down raws li lub vuam txuas ntxiv mus ua vuam slag.
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
Qhov thib ob, vuam slag ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov hlaws vuam thaum lub sijhawm vuam. Lub slag npog cov kua hlau hauv lub pas dej molten kom cais cov kua hlau los ntawm huab cua, tiv thaiv kev nkag mus ntawm cov pa phem xws li oxygen, nitrogen, thiab hydrogen hauv huab cua, yog li tiv thaiv cov hlaws vuam. Yog li ntawd, thaum lub sij hawm vuam txheej txheem, koj yuav tsum tau xyuam xim rau lub vuam lub kaum sab xis kom ntseeg tau tias cov vuam slag ntws mus rau sab nraum qab thiab ob sab ntawm lub nraub qaum, thiaj li saib xyuas qhov tsim ntawm vuam, zam lub cim ntawm qhov tsis xws luag xws li slag. suav nrog thiab pores, thiab xyuas kom cov vuam zoo. Thib peb, raws li tus kws tshaj lij welder ntawm qhov chaw, yog tias koj xav txheeb xyuas cov hlau molten thaum vuam, koj tsuas yog yuav tsum tau ua tib zoo saib thiab koj yuav pom tias cov vuam slag ntab saum cov kua hlau zoo li cov roj hauv dej, ntab ntawm molten pas dej ua ke, uas yog heev yooj yim mus txheeb xyuas.
