AWS A5.4 E312-17 Intsimbi yentsimbi yokuWelding Electrodes Arc Intonga yokuWelding Rods oboniswayo

AWS A5.4 E312-17 Intsimbi yokuWelding Electrodes I-Arc Stick Welding Rods

Inkcazelo emfutshane:

I-AWS E312-17 iyonke-indawo kwaye ifana kakhulu ne-312-16 kodwa i- -17 yokugqoka iqulethe i-silica eninzi kunye ne-titani-um encinci idala umphumo we-"Spray-Arc" xa isetyenziswe kwi-welds ye-fillet ethe tye.

ISO 3581-A E 29 9 R 1 2

INGCACISO NGOKUBANZI

I-rutile-esisiseko ephezulu ye-CrNi-alloyed yonke indawo ye-electrode

Igqwesileyo yokulungisa i-welding

Ingakumbi iphuhliselwe iintsimbi ekunzima ukuweld, ezifana neepleyiti zesikrweqe, austenitic Mn-steels kunye high C-steels

Ukuweldability okugqwesileyo kunye ne-slag yokuzikhulula

IWeldable kwi-AC kunye ne-DC+ polarity

Uhlobo lwangoku: DC/AC+

Inkcazo kunye nezicelo

I-AWS E312-17 iyonke-indawo kwaye ifana kakhulu ne-312-16 kodwa i- -17 yokwambathisa iqulethe i-silica eninzi kunye ne-titanim encinci eyenza i-"Spray-Arc" isiphumo xa isetyenziswe kwi-welds ye-fillet ethe tye.Oku kukwavelisa idiphozithi yeweld enenkangeleko ecolekileyo ye-ripple ethe tyaba ngakumbi ukuze i-concave.I-312-17 ine-slag epholileyo yokukhenkceza inika iimpawu zokuphatha ezingcono xa usebenzisa ubuchule bokutsala.Ukhetho olugqwesileyo kwiintsimbi ezinzima-uku-weld ezifana ne-air-hardening steel, i-medium and high carbon steels.I-electrode efanelekileyo yokusetyenziswa apho isiseko sesinyithi sibakala elingaziwayo lensimbi.Ifanele usetyenziso oluninzi olwahlukileyo olubandakanya intsimbi yokuqina yemanganese, intsimbi yesikrweqe, intsimbi yasentwasahlobo, intsimbi kaloliwe, intsimbi ehonjisiweyo yenickel, isixhobo & intsimbi yokufa kunye nentsimbi yenqwelomoya.Ngokuqhelekileyo isetyenziswa njenge-build-resistant build-up kunye ne-"buffer" umaleko kwizicelo ezijongene nzima.Umsebenzi uba nzima ukuya kuthi ga kwi-200 Brinell.I-312-17 ineyona nto iphezulu kunye namandla emveliso ye-electrode yensimbi engenasici edibeneyo (i-duplex stainless ayibandakanywanga).
