Ucingo olune-cored ye-Fluxsisisombululo esisebenziseka lula nesisebenzayo sokuwelda iintsimbi ze-carbon ephantsi ye-18-20% Cr/8-12% Ni. Olu hlobo lwentambo lwenzelwe ukubonelela ngokuwelda okugqwesileyo kunye neempawu ezintle zoomatshini phantsi kweemeko zokuwelda. Ubukho be-ferrite kwisinyithi sokuwelda kunciphisa ukuqhekeka, okwenza ukuba ibe yeyona ifanelekileyo kwiintlobo ngeentlobo zezicelo zokuwelda. Ukongeza, umxholo ophantsi wekhabhoni unceda ukuphucula ukumelana nokugqwala kwe-intergranular, okwenza kube lukhetho oluthembekileyo kwiiprojekthi ezifuna ukuwelda okusemgangathweni ophezulu.
Xa kudityaniswa intsimbi ethambileyo, ukukhetha intambo enomphetho ojikelezayo kubaluleke kakhulu. Ulwakhiwo olulodwa lwale ntambo yokudityaniswa luqinisekisa ukuba intsimbi yokudityaniswa ephumayo ayichaphazeleki lula kukuqhekeka, ingxaki eqhelekileyo xa usebenza ngentsimbi ethambileyo. Oku kuyenza ilungele ukusetyenziswa apho ukuthembeka kokudityaniswa kubaluleke kakhulu, njengeendawo zesakhiwo okanye zemizi-mveliso.
Enye yezona nzuzo ziphambili zokusebenzisa ucingo olune-flux-core ukuwelda intsimbi ethambileyo kukusebenza kwayo kakuhle kokuwelda. Olu cingo lwenzelwe ukuvelisa ukuwelda okuneempawu ezintle kakhulu zoomatshini phantsi kweemeko zokuwelda, okubonelela ngekhonkco eliqinileyo nelithembekileyo. Oku kubalulekile ukuqinisekisa ukuhlala ixesha elide kunye nokuqina kwezinto eziweldayo, okwenza kube lolona khetho luphambili kwiiprojekthi ezahlukeneyo zokuwelda.
Ukongeza ekubeni neepropati ezintle zokuwelda, ucingo oluthambileyo olune-flux-core lukwanokumelana ngcono nokugqwala kwe-intergranular ngenxa yokuba lune-carbon ephantsi. Oku kubaluleke kakhulu xa kusetyenziswa apho izinto eziweldayo zichaphazeleka kwiindawo ezinobungozi okanye kwizinto ezirhabaxa. Umxholo ophantsi we-carbon unceda ukugcina ukuthembeka kwe-weld, ukuqinisekisa ukusebenza kwexesha elide kunye nokuthembeka.
Ngamafutshane, ucingo olune-flux cored lusisombululo esisebenzayo sokuwelda intsimbi ene-carbon ephantsi ye-18-20% Cr/8-12% Ni. Ukwakheka kwayo kunye neempawu zayo ezikhethekileyo zenza ukuba ilungele ukusetyenziswa okufuna ukuwelda okugqwesileyo, iimpawu zoomatshini kunye nokumelana nokugqwala. Ngokukhetha ucingo olune-flux-cored olufanelekileyo, abawelda banokufikelela kwii-welds ezikumgangatho ophezulu ezihlangabezana nemigangatho ephezulu yokusebenza kunye nokuqina.
