Ii-electrode ze-Metal Arc ezenziwe ngesandlazizixhobo ezibalulekileyo kwi-welding yanamhlanje, zibonelela ngokuguquguquka nokuthembeka kokudibanisa uluhlu olubanzi lweentsimbi. I-electrode ye-Ni202 ngumzekelo ophambili wemveliso enjalo, eyenzelwe ngokukodwa ukuwelda ii-alloys ze-nickel-copper. Ihambelana nemigangatho ye-GB/T EN4060 kunye ne-AWS A5.11 ENiCu-7, iqinisekisa ukusebenza okuzinzileyo kunye nokuqinisekiswa komgangatho wamazwe ngamazwe. Le electrode ibonakaliswa yingqokelela yayo yentsimbi ephambili ye-Ni70Cu30, ehambelana nosapho lwe-alloy ye-Monel, inika ukumelana nokugqwala okugqwesileyo kunye namandla.
I-electrode ye-Ni202 inomgqumo we-titanium-calcium, onegalelo ekusebenzeni kwayo okuzinzileyo kwe-arc kunye nokudluliselwa kwesinyithi okugudileyo. Isinyithi sokufaka siqulethe ubungakanani obulinganisiweyo be-manganese kunye ne-niobium, nto leyo ephucula ukumelana kwayo nokuqhekeka ngexesha nasemva kokuwelda. Oku kuyenza ifaneleke ngakumbi kwizicelo apho uxinzelelo lobushushu kunye nokuqhekeka kokuqina kuyinkxalabo. Ukwakheka kweekhemikhali kuqinisekisa iipropati zoomatshini eziqinileyo kunye nokuqina kwijoyinti eweldayo.
Ngokuphathelele ukusebenza komsebenzi, okuI-Electrode ye-Metal Arc yesandlaigqwesile ngeempawu zayo ezilula ukuyisebenzisa. Isebenza ngokufanelekileyo kwimithombo yamandla etshintshanayo (AC) kunye nemithombo yamandla e-direct current (DC), inika ukuguquguquka kwiindawo ezahlukeneyo zoshishino. Ukutsha kwe-arc kuhamba kakuhle, kwaye inkqubo yokudibanisa ibonakala ngokuchithwa okuncinci kunye nokususwa kwe-slag okulula. Ezi mpawu zinegalelo kwiintsimbi ze-weld ezikumgangatho ophezulu ezinembonakalo entle, nto leyo enciphisa isidingo sokugqitywa okukhulu emva kokudibanisa.
Iinjongo eziphambili ze-electrode ye-Ni202 ziquka ukuwelda ii-alloys ze-nickel-copper kunye neentsimbi ezahlukeneyo, apho iqinisekisa ukuba iindawo ezidibeneyo ziqinile, aziqhekeki. Ikwasetyenziswa njengezinto zokugquma okanye zokugquma ukubonelela ngeendawo ezimelana nokugqwala kwiintsimbi ezisisiseko ezivezwe kwiindawo ezirhabaxa. Amashishini aqhelekileyo axhamla kule mveliso aquka ukucubungula iikhemikhali, ubunjineli bolwandle, kunye neoyile negesi, apho ukuthembeka phantsi kweemeko ezinzima kubalulekile.
I-Ni202 imele ukhetho olukumgangatho ophezulu ngaphakathi kudidi lweIi-electrode ze-Metal Arc ezenziwe ngesandla, edibanisa ukusebenza kakuhle kokuwelda kunye neempawu eziqinileyo zesinyithi. Ukuthobela kwayo imigangatho yamazwe ngamazwe kunye nokuzivumelanisa nokuguquguquka kokuwelda kwe-AC kunye ne-DC kuyenza ibe lukhetho oluthembekileyo kwiingcali ezifuna ukuthembeka nokusebenza kakuhle kwimisebenzi yokuwelda ye-nickel-alloy.
