Iingcingo zokuwelda ezingundoqo ze-Flux ziqulethe izixhobo ezahlukeneyo zokuququzelela inkqubo yokuwelda ngokungafaniyo neengcingo zentsimbi ze-arc zokuwelda eziqinileyo kuyo yonke indawo.Kukho iindidi ezimbini ze-flux cores iingcingo zentsimbi ezingenasici ezizezi: igesi ekhuselweyo kunye nokuzikhusela.Ukusetyenziswa nangona kunjalo kugqitywa ngokuxhomekeke kubume beprojekthi kunye nohlahlo lwabiwo-mali.
Kwiwelding ekhawulezayo ye-arc, igesi ekhuselweyo i-flux cored ingcingo ziyasetyenziswa njengoko zinezinga eliphezulu le-diposition xa kuthelekiswa ne-welder yocingo oluluqilima.Ngokwahlukileyo koko, ucingo alunakukwazi ukuwelda nawuphi na umzimba wentsimbi obhityileyo njengalowo wemoto.
Ucingo lwewelding olukhuselayo kwelinye icala luyakwazi ukuvelisa isikhuselo segesi esisisikrweqe sokhuselo esifunwa zizo zombini iintambo zokuwelda eziqinileyo kunye negesi ukukhusela ukuchaphaza kwentsimbi.Iingcingo ezahlukeneyo zokuwelda ezikhuselweyo ziyafumaneka kwimarike eyilelwe ngokukhethekileyo ukukhonza izikhundla ezizodwa zokuwelda.Ucingo oluzikhuselweyo oluguquguqukayo olunomgangatho ophezulu wokujonga, lujongana nokuwelda kwemizimba yentsimbi engqindilili kuphela.Le propati ifana ncam naleyo yeentambo zentsimbi ezikhuselwe ngegesi.
I-slag yenziwa kwiintambo zegesi ezikhuselweyo ezikhuselweyo, umgangatho owuvumela ukuba udibanise kwi-ampeges ephezulu kune-gas metal arc welding wires.Ukwakhiwa kwe-slag ekhethekileyo akuvumeli i-weld splash ibe yi-fluid.Oku kuvumela umsebenzisi ukuba afake ucingo olukhuselweyo lwegesi kwi-welding yokusetyenziswa ngokuthe nkqo.Emva kokugqitywa kokususwa kwe-welding ye-slag ngumsebenzi onzima xa uthelekisa naleyo ikwi-self shielded flux cored ingcingo.
Ucingo oluzikhuselayo aluvelisi i-slag yokubamba ulwelo kwindawo ye-weld kungoko alunakusetyenziselwa ukuwelda ngokuthe nkqo.Ukususwa kwe-slag kuthatha ixesha elininzi kunye nomzamo kwicala lomsebenzisi.
Ngokutsho kwabaqhubi be-welding kunye nabavelisi bentsimbi yensimbi engenasici imbonakalo ye-weld ibambe ukubaluleka okubalulekileyo kwishishini labo.Ukusebenza kwintsimbi engaphantsi kwee-intshi ze-3/16 & ukuyiguqula ibe yintsimbi encinci ye-24 gauges, ucingo oluqinileyo luya kunika inkangeleko ecocekileyo xa kuthelekiswa neengcingo zombane.Kwindawo apho isantya somoya singenako ukungahoywa, i-slid okanye i-gas shielded flux core wire ayinakusetyenziswa njengoko iya kugqiba ukuveza igesi ekhuselayo kwisantya somoya nto leyo eya kuchaphazela ingqibelelo ye-welding.Ngokwahlukileyo koko, ucingo oluzikhuselayo lulungele ukuwelda kwindawo engaphandle ingakumbi xa kuvuthuza umoya ngesantya esiphezulu.Ucingo olukhuselweyo lunokuthwaleka okuphezulu kuba aludingi gesi yokhuselo lwangaphandle.Ukuphatheka kunceda ukuwelda kumsebenzi wezolimo apho ulungiso lwezixhobo zentsimi lunokuthi lwenzeke ngokukhawuleza ngoncedo lweengcingo ezizikhuselayo ezizikhuselayo njengoko ivenkile yokulungisa iya kuba kumgama weemayile ezimbalwa.Ezi ngcingo zibonelela ngokugqwesileyo kokungena kwiintsimbi ezityebileyo.
Nangona zibiza kakhulu kunocingo oluluqilima, iingcingo eziguquguqukayo zinika imveliso enye.Ngokungafaniyo neengcingo eziqinileyo ziyakwazi ukuwelda izinto ezinomhlwa ende oxhaphakileyo, isikali sokusila okanye iintsimbi ezigqunywe ngeoyile.Izinto ze-de oxidizing ezikhoyo kwiintambo ze-flux cored zisusa ezi zingcolisi ngokuzibamba kwi-slag coverage.
