I-AWS A5.4 E312-17 Ukuwelda kweNtsimbi Engagqwaliyo Ii-Electrode ze-Arc Stick Ukuwelda Iintambo Umfanekiso obonisiweyo

Ii-AWS A5.4 E312-17 zokuWelda zentsimbi engagqwaliyo ii-electrode ze-arc stick welding rods

Inkcazo emfutshane:

I-AWS E312-17 ikwindawo yonke kwaye ifana kakhulu ne-312-16 kodwa i--17 coating ine-silica eninzi kunye ne-titani-um encinci edala isiphumo se-"Spray-Arc" xa isetyenziswa kwi-horizontal fillet welds.

Udidi:

I-AWS A5.4 E312-17

I-ISO 3581-A E 29 9 R 1 2

INKCAZELO NGOKUBANZI

I-electrode yesikhundla esiphezulu se-rutile-basic CrNi-alloyed all position

Ilungele ukulungisa ukuwelda

Yenzelwe ngokukodwa iintsimbi ekunzima ukuzidibanisa, ezifana neepleyiti zezixhobo, iintsimbi ze-austenitic Mn kunye neentsimbi ze-C eziphezulu

Ukuwelda okugqwesileyo kunye ne-slag yokukhulula ngokwayo

Iyashibilika kwi-AC kunye ne-DC+ polarity

Uhlobo lwangoku: DC/AC+

Inkcazo kunye nezicelo

I-AWS E312-17 ikwindawo yonke kwaye ifana kakhulu ne-312-16 kodwa i--17 coating ine-silica eninzi kunye ne-titanium encinci edala isiphumo se-"Spray-Arc" xa isetyenziswa kwi-fillet welds ezithe tye. Oku kukwavelisa idiphozithi ye-weld enembonakalo entle ye-ripple ethe tyaba ngakumbi ukuya kwi-concave. I-312-17 ine-slag ebandayo ecothayo enika iimpawu zokuphatha ezingcono xa usebenzisa indlela yokutsala. Ukhetho oluhle kakhulu kwiintsimbi ezinzima ukuwelda ezifana nentsimbi yokuqinisa umoya, iintsimbi zekhabhoni eziphakathi neziphezulu. I-electrode efanelekileyo yokusebenzisa apho isinyithi esisisiseko siluhlobo lwentsimbi olungaziwayo. Ifanelekile kwiintlobo ezininzi ezahlukeneyo ezibandakanya isinyithi sokuqinisa i-manganese, intsimbi ye-armor, intsimbi yespring, intsimbi yerail, intsimbi ye-nickel clad, intsimbi yesixhobo kunye ne-die kunye nentsimbi yeenqwelo-moya. Isetyenziswa rhoqo njengomaleko we-build-up onganyangekiyo kunye "ne-buffer" kwizicelo ezijongene nobunzima. Umsebenzi uqina ukuya kuthi ga kwi-200 Brinell. I-312-17 inamandla aphezulu okutsalwa kunye nokukhupha ii-electrodes ezifakwe intsimbi engagqwaliyo (i-duplex stainless stainless ayifakwanga).
