Ucingo olune-cored lwe-Fluxiyisisombululo esisebenziseka kalula nesisebenzayo sokushisela izinsimbi ze-carbon ephansi engu-18-20% Cr/8-12% Ni. Lolu hlobo lwentambo lwenzelwe ukuhlinzeka ngokushisela okuhle kakhulu kanye nezakhiwo ezinhle kakhulu zemishini ngaphansi kwezimo zokushisela. Ukuba khona kwe-ferrite ensimbini yokushisela kunciphisa ukuthambekela kokuqhekeka, okwenza kube kuhle kakhulu ezinhlotsheni ezahlukene zezicelo zokushisela. Ngaphezu kwalokho, okuqukethwe okuphansi kwekhabhoni kusiza ekuthuthukiseni ukumelana nokugqwala kwe-intergranular, okwenza kube ukukhetha okuthembekile kwamaphrojekthi adinga ukushisela kwekhwalithi ephezulu.
Lapho kushintshwa insimbi ethambile, ukukhetha intambo ene-flux-core kubalulekile. Ukwakheka okuhlukile kwale ntambo yokushintshwa kuqinisekisa ukuthi insimbi yokushintshwa ephumayo ayiqhekeki kalula, okuyinkinga evamile lapho kusetshenzwa ngensimbi ethambile. Lokhu kuyenza ifaneleke kakhulu ekusetshenzisweni lapho ubuqotho bokushintshwa bubaluleke kakhulu, njengezindawo zesakhiwo noma zezimboni.
Enye yezinzuzo eziyinhloko zokusebenzisa ucingo olune-flux-core ukushisela insimbi ethambile ukusebenza kwayo okuhle kakhulu kokushisela. Lolu cingo lwenzelwe ukukhiqiza ukushisela okunezakhiwo ezinhle kakhulu zomshini ngaphansi kwezimo zokushisela, okuhlinzeka ngesibopho esiqinile nesithembekile. Lokhu kubalulekile ukuqinisekisa ukuhlala isikhathi eside nokuqina kwezingxenye ezishiselwe, okwenza kube ukukhetha kokuqala kwemiklamo eyahlukahlukene yokushisela.
Ngaphezu kokuba nezakhiwo ezinhle kakhulu zokushisela, ucingo oluthambile olune-flux-core luphinde lukwazi ukumelana kangcono nokugqwala kwe-intergranular ngenxa yokuqukethwe kwalo okuphansi kwekhabhoni. Lokhu kubaluleke kakhulu ekusetshenzisweni lapho izingxenye ezishisiwe zivezwa khona ezindaweni ezinzima noma izinto ezibolile. Ukuqukethwe okuphansi kwekhabhoni kusiza ukugcina ubuqotho be-weld, okuqinisekisa ukusebenza kwesikhathi eside nokuthembeka.
Ngamafuphi, ucingo olune-flux cored luyisisombululo esisebenzayo sokushisela insimbi ene-carbon ephansi engu-18-20% Cr/8-12% Ni. Ukwakheka kwayo okuyingqayizivele kanye nezakhiwo zayo kwenza kube kuhle kakhulu ekusetshenzisweni okudinga ukushisela okuhle kakhulu, izakhiwo zemishini kanye nokumelana nokugqwala. Ngokukhetha ucingo olune-flux-cored olufanele, abashisela bangafinyelela ukushisela kwekhwalithi ephezulu okuhlangabezana nezindinganiso eziphakeme zokusebenza nokuqina.
