Manual Metal Arc Electrodeszvishandiso zvakakosha mukunamira kwesimbi kwemazuva ano, zvichipa kushanduka-shanduka uye kuvimbika pakubatanidza simbi dzakasiyana-siyana. Electrode yeNi202 muenzaniso mukuru wechigadzirwa chakadaro, chakagadzirirwa zvakanangana nekunamira nickel-copper alloys. Inoenderana nezvinodiwa zveGB/T EN4060 uye AWS A5.11 ENiCu-7, ichivimbisa kushanda kwakafanana uye kuvimbiswa kwemhando yepasi rose. Electrode iyi inozivikanwa nekuumbwa kwayo kwewaya yepakati yeNi70Cu30, iyo inoenderana nemhuri yeMonel alloy, ichipa kudzivirira ngura uye simba rakanaka.
Electrode yeNi202 ine titanium-calcium coating, iyo inobatsira kuti ishande zvakanaka uye simbi inofamba zvakanaka. Simbi iyi ine huwandu hwakanyatsorongeka hwemanganese neniobium, zvichiita kuti irambe ichikwanisa kupwanyika panguva yekuwelda uye mushure mekuwelda. Izvi zvinoita kuti ive yakakodzera kushandiswa uko kune kunetseka nekupisa uye kuomarara kwekupwanyika. Kuumbwa kwemakemikari kunovimbisa hunhu hwakasimba hwemakanika uye kugara kwenguva refu mujoini yakawelda.
Panyaya yekushanda, izviManual Metal Arc ElectrodeInoshanda zvakanaka nemaitiro ayo ari nyore kushandisa. Inoshanda zvinobudirira pamagetsi anochinjana (AC) uye magetsi akananga (DC), ichipa kuchinjika munzvimbo dzakasiyana dzemaindasitiri. Kubatidza kwearc kwakapfava, uye maitiro ekubatanidza anoratidzwa nekusaisa mvura zvishoma uye kubviswa kwemarara kuri nyore. Hunhu uhwu hunobatsira pakushongedza mabhora emhando yepamusoro ane chitarisiko chinoyevedza, zvichideredza kudiwa kwekupedzisa kwakawanda mushure mekushongedza.
Mashandisirwo makuru eNi202 electrode anosanganisira kusundira nickel-copper alloys nesimbi dzakasiyana, uko kunoita kuti pave nemajoini akasimba, asingatsemuke. Inoshandiswawo sechivharo kana chinhu chinofukidza ngura kuti ipe nzvimbo dzisingatsvedzeri ngura pasimbi dzakaiswa munzvimbo dzine hukasha. Maindasitiri anowanzo batsirwa nechigadzirwa ichi anosanganisira kugadzira makemikari, uinjiniya hwegungwa, uye mafuta negasi, uko kuvimbika mumamiriro ezvinhu akaomarara kwakakosha.
Iyo Ni202 inomiririra sarudzo yepamusoro-soro mukati mechikamu cheManual Metal Arc Electrodes, ichibatanidza kushanda kwayo kwakanaka kwewelding pamwe nehunhu hwakasimba hwesimbi. Kutevedzera kwayo mitemo yepasi rose uye kugona kwayo kuchinjika kune ese ari maviri AC neDC welding kunoita kuti ive sarudzo yakavimbika kune nyanzvi dzinotsvaga kuvimbika uye kushanda zvakanaka mumabasa ewelding enickel-alloy.
