Induku yokushisela ye-E312 Ihlangabezana nezimfuneko ze-AWS E312-17 futhi iyisisombululo esithandwayo sokushisela i-arc ngesandla esinamathelayo (SMAW) esiguquguqukayo, esinobungcweti obuphezulu. Yakhelwe ukushisela kuzo zonke izindawo, i-electrode iphumelela kakhulu ezimweni zokwenziwa nokulungiswa eziyinkimbinkimbi ngezinkomba zokushisela ezishintshayo. Inzuzo yayo eyinhloko yikhono layo lokwenza idiphozithi eqinile, engaqhekeki ye-austenitic ezintweni ezahlukahlukene eziyisisekelo eziyinselele, kufaka phakathi izinsimbi ezingagqwali ezahlukahlukene, inhlanganisela yensimbi engafani kanye namazinga ensimbi ane-alloy ephezulu, ikakhulukazi ezimweni lapho ukumelana nokushaqeka kokushisa kubaluleke kakhulu.
Ama-electrode e-E312 asebenzisa idiphozithi ye-electrode ye-austenitic ebonakala ngokuqukethwe okuphezulu kwe-chromium kanye nokuqukethwe okuphezulu kwe-nickel. Lokhu kwakheka okukhethekile kuyinika ukumelana okuhle kakhulu nokuqhekeka okushisayo, okuyinkinga evamile lapho kushiswa amalunga acindezelwe kakhulu, izinsimbi ezingafani, noma izinsimbi eziqhekeka kalula. Insimbi eshisiwe ephumelayo ibonisa amandla amahle kakhulu okuxhunywa kokubili emazingeni okushisa asekamelweni kanye nasezingeni lokushisa eliphakeme, futhi inokuguquguquka okuhle kanye nokuqina komthelela.
I-E312-17 ihlukile ngezakhiwo zayo zokuphatha ezilungiselelwe kahle.Induku yokushisela ye-E312 (AWS E312-17) ifana ne-electrode ye-E312-16, kodwa ukwakheka kwayo kokumboza kukhulise okuqukethwe kwe-silicon kanye nokuqukethwe kwe-titanium okuncishisiwe. Lokhu kulungiswa ngokucophelela kuthuthukisa kakhulu ukuzinza kwe-arc kuzo zonke izikhundla, ikakhulukazi kuma-weld e-fillet angaphezulu okunzima kanye nama-weld aqonde phezulu. Le khemistri ikhiqiza umphumela ohlukile we-"jet arc" uma isetshenziswa kuma-weld e-fillet avundlile.
I-electrode ye-E312 inezinhlobo eziningi kakhulu zezicelo. Iyindlela esetshenziswayo yokuhlanganisa izinsimbi ezingafani, izinsimbi ezingagqwali ze-austenitic nezinsimbi ze-carbon noma ze-alloy eziphansi, kanye nezinsimbi ze-nickel eziphakeme nezinsimbi. Isebenza kahle kakhulu ekusetshenzisweni kokumboza kanye nokumboza lapho kudingeka khona ukumelana nokuguguleka nokugqwala. I-electrode ibhekwa kakhulu nasekulungiseni ukushisela kwezinto ezisetshenziswayo ezivame ukuqhekeka. Izimboni ezibalulekile ezithembele ekusebenzeni kwayo zifaka phakathi ukukhiqizwa kwamandla, ukucubungula ngamakhemikhali kanye ne-petrochemical, i-pulp nephepha, kanye nokukhiqizwa kanye nokugcinwa kwemishini esindayo.
Induku yokushisela ye-E312 (AWS E312-17) inikeza ukuguquguquka okungenakuqhathaniswa kanye nokuthembeka emisebenzini yokushisela edinga ukushisela yonke indawo, ukumelana okuhle kakhulu kokuqhekeka kanye nokufakwa kwamandla aphezulu. I-chemistry yayo ekhethekile yokumboza iyinika umphumela omuhle kakhulu we-"jet arc", ovumela ukushisela okuhle kakhulu kwe-fillet okuvundlile, okunikeza i-welder izici zokulawula ezingcono kanye nokubeka. Insimbi yokushisela ye-austenitic ephumelayo inokumelana okuhle kakhulu nokuqhekeka okushisayo kanye nokuxuba, okwenza ibe yi-electrode ebalulekile yokuxhumana okubalulekile njengezinsimbi ezingafani, izinsimbi ezine-alloy ephezulu, kanye nemisebenzi yokulungisa eyinkimbinkimbi.
