Ama-electrode e-Metal Arc enziwe ngesandlazingamathuluzi abalulekile ekushiseleni kwesimanje, ezinikeza ukuguquguquka nokuthembeka kokuhlanganisa izinhlobo eziningi zezinsimbi. I-electrode ye-Ni202 iyisibonelo esiyinhloko somkhiqizo onjalo, owenzelwe ngqo ukushisela ama-alloy e-nickel-copper. Ihambisana nezindinganiso ze-GB/T EN4060 kanye ne-AWS A5.11 ENiCu-7, okuqinisekisa ukusebenza okulinganayo kanye nokuqinisekiswa kwekhwalithi yamazwe ngamazwe. Le electrode ibonakala ngokwakheka kwayo kwentambo eyinhloko ye-Ni70Cu30, ehambisana nomndeni we-alloy ye-Monel, enikeza ukumelana nokugqwala okuhle kakhulu namandla.
I-electrode ye-Ni202 ine-titanium-calcium coating, enegalelo ekusebenzeni kwayo okuzinzile kwe-arc kanye nokudluliswa kwensimbi okubushelelezi. Insimbi yokufaka iqukethe inani elilinganiswe kahle le-manganese ne-niobium, okwandisa ukumelana kwayo nokuqhekeka ngesikhathi nangemva kokushisela. Lokhu kuyenza ifaneleke kakhulu ekusetshenzisweni lapho ukucindezeleka kokushisa kanye nokuqhekeka kokuqina kuyinkinga. Ukwakheka kwamakhemikhali kuqinisekisa izakhiwo eziqinile zemishini kanye nokuqina kwejoyinti elishisiwe.
Ngokuphathelene nokusebenza kahle, lokhuI-Electrode ye-Metal Arc yesandlaiphumelela kakhulu ngezici zayo ezilula ukuyisebenzisa. Isebenza kahle kokubili emithonjeni yamandla eshintshashintshayo (AC) kanye nemithombo yamandla kagesi eqondile (DC), inikeza ukuguquguquka ezindaweni ezahlukene zezimboni. Ukushiswa kwe-arc kubushelelezi, futhi inqubo yokushiswa ibonakala ngokuchitheka okuncane kanye nokususwa okulula kwe-slag. Lezi zimfanelo zinegalelo ekushisweni kwekhwalithi ephezulu okubonakala kujabulisa ubuhle, kunciphisa isidingo sokuqedwa okukhulu ngemva kokushiswa.
Ukusetshenziswa okuyinhloko kwe-electrode ye-Ni202 kufaka phakathi ukushisela ama-alloy e-nickel-copper kanye nezinsimbi ezingafani, lapho kuqinisekisa khona amalunga aqinile, angaqhekeki. Iphinde isetshenziswe njengendwangu yokumboza noma yokumboza ukuze inikeze izindawo ezingagqwali ezisekelweni zensimbi ezivezwe ezindaweni ezinolaka. Izimboni ezivamile ezizuza kulo mkhiqizo zifaka phakathi ukucubungula amakhemikhali, ubunjiniyela basolwandle, kanye namafutha negesi, lapho ukuthembeka ngaphansi kwezimo ezidinga kakhulu kubalulekile.
I-Ni202 imelela inketho esezingeni eliphezulu ngaphakathi kwesigaba se-Ama-electrode e-Metal Arc enziwe ngesandla, ehlanganisa ukusebenza kahle kakhulu kokushisela kanye nezakhiwo eziqinile zensimbi. Ukuhambisana kwayo nezindinganiso zomhlaba wonke kanye nokuzivumelanisa nezimo kokubili ukushisela kwe-AC kanye ne-DC kwenza kube ukukhetha okuthembekile kochwepheshe abafuna ukuthembeka nokusebenza kahle emisebenzini yokushisela ye-nickel-alloy.
