Intonga yokuwelda ye-E312 Ihlangabezana neemfuno ze-AWS E312-17 kwaye sisisombululo esikhethwayo sokuwelda i-arc ngesandla (SMAW) eguquguqukayo, ekumgangatho ophezulu. Yenzelwe ukuwelda kwindawo yonke, i-electrode igqwesile kwiimeko ezinzima zokwenza nokulungisa kunye neendlela zokutshintsha zokuwelda. Inzuzo yayo ephambili kukukwazi kwayo ukwenza idiphozithi enamandla, engaqhekekiyo kwizixhobo ezahlukeneyo ezisisiseko ezinzima, kubandakanya iintsimbi ezahlukeneyo ezingenasici, imixube yesinyithi eyahlukileyo kunye neendidi zentsimbi ezine-alloy ephezulu, ngakumbi kwiimeko apho ukumelana nobushushu kubaluleke kakhulu.
Ii-electrode ze-E312 zisebenzisa idiphozithi ye-electrode ye-austenitic ephawulwa ngumxholo ophezulu we-chromium kunye nomxholo ophezulu we-nickel. Olu lwakhiwo lukhethekileyo luyinika ukumelana okuhle kakhulu nokuqhekeka okushushu, okuyingxaki eqhelekileyo xa kudityaniswa amalungu axineneyo kakhulu, iintsimbi ezahlukeneyo, okanye iintsimbi eziqhekeka lula. Intsimbi ye-weld ephumayo ibonisa amandla agqwesileyo okutsalwa kubushushu begumbi kunye nobushushu obuphezulu, kwaye inokuqina okuhle kunye nokuqina kwempembelelo.
I-E312-17 ikhethekile kwiipropati zayo zokuphatha ezilungiselelwe kakuhle.Intonga yokuwelda ye-E312 (AWS E312-17) ifana ne-electrode ye-E312-16, kodwa indlela yayo yokugquma inyuse umxholo we-silicon kwaye inciphise umxholo we-titanium. Olu hlengahlengiso luphucula kakhulu uzinzo lwe-arc kuzo zonke iindawo, ingakumbi kwii-welds ezinzima ze-overhead fillet kunye nee-welds ezithe nkqo. Le khemistri ivelisa isiphumo esikhethekileyo se-"jet arc" xa isetyenziswa kwii-welds ze-fillet ezithe tye.
I-electrode ye-E312 inoluhlu olubanzi kakhulu lwezicelo. Yeyona isetyenziswa kakhulu ekudibaniseni iintsimbi ezahlukeneyo, iintsimbi ezingenasici ze-austenitic kwi-carbon okanye iintsimbi ze-alloy eziphantsi, kunye nee-alloy eziphezulu ze-nickel kwintsimbi. Isebenza kakhulu kwizicelo ze-overlay kunye ne-cladding apho kufuneka khona ukumelana nokuguguleka nokubola. I-electrode ikwajongwa kakhulu ekulungiseni i-welding ye-castings enokuqhekeka. Amashishini aphambili axhomekeke ekusebenzeni kwayo aquka ukuveliswa kombane, ukucubungula iikhemikhali kunye ne-petrochemical, i-pulp kunye nephepha, kunye nokuveliswa kunye nokugcinwa kwezixhobo ezinzima.
Intonga yokuwelda ye-E312 (AWS E312-17) inika ukuguquguquka okungenakuthelekiswa nanto kunye nokuthembeka kwimisebenzi enzima yokuwelda efuna ukuwelda kwindawo yonke, ukumelana nokuqhekeka okugqwesileyo kunye nokufakwa kwamandla aphezulu. Ikhemikhali yayo ekhethekileyo yokugquma inika isiphumo esihle kakhulu se-"jet arc", esenza ukuba i-fillet welds ethe tye ibe nomtsalane, inika i-welder ulawulo olungcono kunye neempawu zokubeka. I-austenitic weld metal ephumayo inokumelana okugqwesileyo nokuqhekeka okushushu kunye nokuxutywa, okwenza ukuba ibe yi-electrode ebalulekileyo kwiikhonkco ezibalulekileyo ezifana neentsimbi ezahlukeneyo, iintsimbi ezine-alloy ephezulu, kunye nemisebenzi yokulungisa enzima.
