Ucingo lwe-AWS A5.17 EM12K olufakwe phantsi komhlaba lunezinga eliphezulu lekhabhoni, i-manganese, kunye ne-silicon kunemveliso efanayo, i-EL12. Olu lwakhiwo lukhethekileyo ludlala indima ebalulekileyo kwinkqubo yokudibanisa njengoko lunceda ukonyusa amandla kunye nokuqina kwe-weld iyonke. I-Carbon ibalulekile ekwandiseni ubulukhuni, ngelixa i-manganese inyusa ukumelana kwe-weld ekuqhekekeni kwaye iphucula ukuhamba kwamanzi ngexesha lokudibanisa. I-Silicon, kwelinye icala, isebenza njenge-deoxidizer, iqinisekisa i-weld ecocekileyo engenakungcola okuninzi. Xa zidibene, ezi zinto zenza i-EM12K ibe lukhetho olufanelekileyoukuwelda ngentsimbi yekhabhoni, ingakumbi kwizicelo ezifuna umgudu apho ubulungisa besakhiwo bubaluleke kakhulu.
Enye yezona nzuzo ziphambili zokusebenzisa ucingo lwe-AWS A5.17 EM12K olufakwe kwi-arc welding kwi-carbon steel welding kukukwazi kwayo ukuvelisa ii-deep penetration welds. Inkqubo ye-arc efakwe kwi-arc ivumela amazinga aphezulu okufaka, oku kuthetha ukuwelda ngokukhawuleza kunye nokwanda kwemveliso. Oku kuluncedo ngakumbi kwiiprojekthi ezinkulu apho ukusebenza kakuhle kwexesha kubalulekile. Ukongeza, ukungena ngokunzulu kuqinisekisa ukuba i-weld inamandla kwaye inokumelana noxinzelelo olukhulu, okwenza ifaneleke kwizicelo ezinzima ezifana nokwakha iinqanawa, ukwakha, kunye nokuvelisa oomatshini abanzima.
Ukusebenzisa ucingo lwe-EM12K kwi-carbon steel welding kunciphisa ukutshiza kwaye kufezekisa umphezulu ogudileyo. Inkqubo yokutshiza i-arc engaphantsi komhlaba inomaleko we-granular flux ekhusela i-arc ekungcoleni komoya kwaye inciphise inani lokutshiza okwenziwe ngexesha lokutshiza. Oku kubangela indawo yokusebenza ecocekileyo kwaye kuncitshiswe ukucocwa emva kokutshiza, ekugqibeleni konga ixesha kunye nezixhobo. Umphezulu ogudileyo ofezekiswa ngocingo lwe-EM12K ukwaphucula ubuhle bemveliso yokugqibela, okwenza ukuba ibe lolona khetho luphezulu kwiindlela zokusebenza apho imbonakalo ibalulekile.
Ucingo lokuwelda oluphantsi kwe-arc oluyi-AWS A5.17 EM12K lukhetho oluhle kakhuluukuwelda ngentsimbi yekhabhoni, enika uluhlu lweenzuzo eziphucula umgangatho kunye nokusebenza kakuhle kwenkqubo yokudibanisa. Ukwakheka kwayo okwahlukileyo, okuphawulwa yikhabhoni ephezulu, i-manganese kunye nomxholo we-silicon, kuqinisekisa ukudityaniswa okuqinileyo nokuhlala ixesha elide okunokumelana nobunzima bezicelo ezifuna amandla. Ikwazi ukuvelisa ukudityaniswa okunzulu, ukusasazeka okuncinci kunye neendawo ezigudileyo, ucingo lokudibanisa lwe-EM12K sisisombululo esithembekileyo kumashishini afuna ukudityaniswa okusebenzayo okuphezulu. Njengoko imfuno yezisombululo zokudibanisa eziqinileyo nezisebenzayo iqhubeka ikhula, ukwamkelwa kwezixhobo eziphambili ezifana ne-AWS A5.17 EM12K ngokuqinisekileyo kuya kudlala indima ebalulekileyo ekubumbeni ikamva lokudityaniswa kwentsimbi yekhabhoni.
