I-E6012 yinjongo jikelele ye-electrode enikezela ngeempawu ezibalaseleyo zokuvala ibhuloho, ngakumbi kwizicelo ezinokufakwa okulambathayo.
I-E6012 ine-arc elungileyo, ezinzileyo kwaye isebenza kwimisinga ephezulu ene-spatter ephantsi.Iguquguquka kakhulu, i-E6012 ingasetyenziselwa zombini amandla e-AC kunye ne-DC.
Usetyenziso oluqhelekileyo: izixhobo zasefama, ukulungiswa jikelele, ukwenziwa koomatshini, ifenitshala yentsimbi, intsimbi yokuhombisa, iishiti lentsimbi, amatanki
Iinkcukacha ze-AWS: AWS A5.1 E6012
Iinkcukacha zeJIS: D4312

I. IZICELO:
Ukwenziwa kwentsimbi ethambileyo, iifestile zentsimbi kunye neentsimbi zentsimbi kunye neengcingo, intsimbi yesikhongozeli, ukuwelda kwemibhobho engavalekanga, izakhiwo zentsimbi zezindlu, izitulo zentsimbi kunye neetafile, iileli zentsimbi kunye nezinye iintsimbi ezilula kunye nezinye.
II.INGCACISO:
I-electrode ye-Welding ye-Shielded Metal Arc eneenjongo ezilungileyo zokudibanisa kunye nokungena.Ifaneleke kakuhle ukuvala izikhewu kwimisebenzi engekho mgangathweni.Izibambo ngokulula kwiphepha elikhanyayo lesinyithi kunye nakwizakhiwo zentsimbi ezinzima.IWeld ineentsimbi ezigudileyo, ezingqukuva kakuhle kunye namaso anomphezulu ojikelezileyo.Iifillet ziconvex ngaphandle kokucuthwa.Ukusebenza kwayo yonke indawo, kudityaniswe nentsimbi ye-weld ekhawulezayo ekhenkcezayo kunye ne-arc enamandla yenza i-electrode efanelekileyo yokusebenzela kunye neemeko zesayithi.Iimpawu ezigqwesileyo zokubeka xa welding zombini ngokuthe nkqo-phezulu kwaye nkqo-phantsi.I-slag iphuma ngokulula kwaye kwiimeko ezininzi iyazikhulula.
III.AMANQAKU OKUSETYENZISWA:
Nika ingqalelo ukuba ungagqithi kuluhlu lwemisinga efanelekileyo.Ukuwelda ngomsinga ogqithisileyo akwehlisi nje isandi se-X-reyi kuphela, kodwa kubangela ukwanda kwe-spatter, ukusika ngaphantsi kunye nokungonelanga kwesigqubuthelo se-slag.
Yomisa i-electrodes kwi-70-100 degrees C imizuzu engama-30-60 ngaphambi kokusetyenziswa.Ukufunxa ngokugqithisileyo kokufuma kwehlisa ukusebenziseka kwaye kunokukhokelela kwezinye iiporosities.
Ukomisa ngokugqithiseleyo ngaphambi kokusetyenziswa kubangela ukuba kuncinci ukungena kunye nokushisa kwe-electrode
