Nickel leNickel Alloy Welding Electrode
Ni307-4
GB/T ENi6093
AWS A5.11 ENCrFe-4
Tlhaloso: Ni307-4 ke electrode e thehiloeng ho nickel e nang le litlolo tse tlaase tsa hydrogen sodium.Sebelisa DCEP (electrode ea hona joale e tobilengntle).E na le ts'ebetso e ntle ea welding e nang le mollo o tsitsitseng oa arc, spatter e nyane, ho tlosa slag habonolo,
le weld e ntle.
Kopo: E sebelisoa bakeng sa ho cheselletsa li-alloys tsa nickel-chromium-iron, tse kang Ni600, Ni800 / 800H le li-superalloys tse tšoanang kapa tsa nickel tse nang le mocheso o sebetsang oa 900 ° C. E ka boela ea sebelisoa bakeng sa litšepe tse nang le mocheso o tlaase o nang le Ni3% ~ 9%, joalo ka ASTM A333, A334, A353, A522, The welding ea A553 e ka boela ea sebelisoa bakeng sa tjheseletsa ea tšepe e sa tšoaneng pakeng tsa Mo400, Ni825, tšepe e sa hloekang le tšepe e tlaase ea alloy.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):

Nako e khothalelitsoeng:
Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 |
Hona joale welding (A) | 60 ~ 90 | 80 ~ 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.Leka ho sebelisa arc e khuts'oane ho cheselletsa.
