Nickel le Nickel Alloy Welding Electrode
Ni327
GB/T ENi6094
AWS A5.11 ENCrFe-9
Tlhaloso: Ni327 ke electrode e thehiloeng ho nickel e nang le sodium e tlaase ea hydrogen.Sebelisa DCEP (electrode ea hona joale e tobilengntle).Tšepe e kentsoeng e na le khanyetso e ntle ea crack hobane weld e na le palo e itseng ea lintho tse kopantsoeng tse kang molybdenum le niobium.
Kopo: E sebelisetsoa ho cheselletsa li-alloys tsa nickel tse hlokang ho hanyetsa mocheso le ho hanyetsa ho bola, 'me e ka boela ea sebelisoa bakeng sa ho cheselletsa le ho hlahisa li-alloys tse thata ho tjheseletsa le litšepe tse sa tšoaneng.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):

Nako e khothalelitsoeng:
| Bophara ba molamu (mm) | 3.2 | 4.0 |
| Hona joale welding (A) | 90 ~ 110 | 110 ~ 150 |
Tlhokomeliso:
1. Electrode e tlameha ho behoa hora e le 1 ho pota 300 ℃ pele ho ts'ebetso ea welding;
2. Ke habohlokoa hore u hloekise mafome, oli, metsi le litšila holim'a likarolo tsa ho cheseletsa pele u cheselletsa.
