Iintambo zokuwelda zentsimbi engagqwaliyo zeFlux core zinezinto ezahlukeneyo zokwenza lula inkqubo yokuwelda ngokungafaniyo neentambo zokuwelda zentsimbi yegesi eziqinileyo kuyo yonke indawo. Kukho iintlobo ezimbini zeentambo zentsimbi engagqwaliyo ze-flux ezizii-gas shielded kunye nezizikhuselayo. Nangona kunjalo, ukusetyenziswa kuthathwa isigqibo ngokuxhomekeke kuhlobo lweprojekthi kunye nohlahlo-lwabiwo mali.
Kwi-arc welding ekhawulezayo, kusetyenziswa iingcingo ezine-gas shielded flux cored cored kuba zinezinga eliphezulu lokulahla inkunkuma xa kuthelekiswa ne-solid wire welder. Ngokwahlukileyo koko, iingcingo azinakukwazi ukuwelda nawuphi na umzimba wesinyithi obhityileyo njengowemoto.
Kwelinye icala, ucingo oluzikhuselayo luyakwazi ukuvelisa ukhuselo lwegesi oluyimfuneko kwiintambo zokukhusela eziqinileyo nezikhusela igesi ukukhusela ukutshiza kwesinyithi. Iintambo ezahlukeneyo zokuzikhusela ezizikhuselayo ziyafumaneka kwimarike zenzelwe ngokukodwa ukukhonza indawo nganye yokuzidibanisa. Intambo ekhuselweyo ye-flux cored enesantya esiphezulu sokulungiswa, ilungele ukudityaniswa kwemizimba yesinyithi etyebileyo kuphela. Olu phawu lufana kakhulu nolweentambo zentsimbi ezingenasici ezikhuselweyo ze-flux cored cored zegesi.
I-slag yenziwa kwiintambo ezifakwe i-flux cored ezikhuselwe yigesi, umgangatho ovumela ukuba i-weld idityaniswe kwi-amperage ephezulu kuneentambo zokuwelda ze-arc zesinyithi segesi. Ukwakheka kwe-slag ekhethekileyo akuvumeli i-weld splash ibe yi-fluid. Oku kwenza umsebenzisi akwazi ukusebenzisa ucingo olukhuselwe yigesi kwi-welding ethe nkqo. Emva kokugqiba ukuwelda ukususa i-slag ngumsebenzi olula xa kuthelekiswa nalowo kwiintambo ezifakwe i-flux cored ezikhuselweyo.
Ucingo oluzikhuselayo aluvelisi i-slag ukuze lubambe ulwelo kwindawo yokuwelda, ngoko ke alunakusetyenziswa kwi-welding ethe nkqo. Ukususa i-slag kuthatha ixesha elininzi kunye nomgudu omkhulu kumsebenzisi.
Ngokutsho kwabaqhubi be-welding kunye nabavelisi beengcingo zentsimbi engagqwaliyo, imbonakalo ye-weld ibaluleke kakhulu kwishishini labo. Ukusebenza kwisinyithi esingaphantsi kwe-3/16 intshi kwaye siyiguqula ibe yishiti yesinyithi ebhityileyo yeegauge ezingama-24, intambo eqinileyo iya kubonelela ngenkangeleko ecocekileyo xa ithelekiswa neengcingo ze-flux. Kwindawo apho isantya somoya singenakutyeshelwa khona, intambo ye-flux core ekhuselweyo okanye enegesi ayinakusetyenziswa njengoko iya kubonakalisa igesi yokukhusela kwisantya somoya nto leyo eya kuchaphazela ukuthembeka kwe-welding. Intambo ekhuselweyo ngokwahlukileyo koko ifanelekile ekudibaniseni kwindawo engaphandle ngakumbi xa umoya uvuthuza ngesantya esiphezulu. Intambo ekhuselweyo ngokwayo inokuthwala okuphezulu kuba ayifuni igesi yokukhusela yangaphandle. Ukuthwaleka kwayo kunceda ukudibanisela kwimisebenzi yezolimo apho ukulungiswa kwezixhobo zasentsimini kungenziwa ngoko nangoko ngoncedo lweengcingo ze-flux core ezikhuselweyo ngokwazo njengoko ivenkile yokulungisa iya kuba ziikhilomitha ezimbalwa ukusuka apho. Ezi ngcingo zibonelela ngokungena okuhle kwiintsimbi ezityebileyo.
Nangona zibiza kakhulu kuneentambo eziqinileyo, iintambo ezixineneyo ze-flux zinika enye imveliso engakumbi. Ngokungafaniyo neentambo eziqinileyo, ziyakwazi ukuwelda izinto ezine-rust ende, isikali se-mill okanye iintsimbi ezigqunywe ngeoyile. Izinto ezisusa i-oxidizing ezikhoyo kwiintambo ezixineneyo ze-flux zisusa ezi zinto zingcolisayo ngokuzigcina kwindawo egqunywe yi-slag.
