Nickel le Nickel Alloy Welding Electrode
Ni307-2
GB/T EN6133
AWS A5.11ENiCrFe-2
Tlhaloso: Ni307-2 ke electrode e thehiloeng ho nickel e nang le sodium e tlaase ea hydrogen.Sebelisa DCEP (electrode e nepahetseng hona joale).Kaha weld e na le palo e itseng ea molybdenum, niobium le likarolo tse ling tsa motsoako, tšepe e kentsoeng e na le khanyetso e ntle ea ho peperana.
Kopo: E sebelisetsoa ho cheselletsa li-alloys tsa nickel-chromium-iron (joalo ka UNS N08800, UNS N06600), haholo-holo tse loketseng bakeng sa tjheseletsa ea litšepe tse sa tšoaneng, tjheseletsa ea lera la phetoho le ho tjheseletsa holimo, hape e ka sebelisoa ha mocheso o sebetsang o le 980 ° C, empa e ka hanana le oxidation ha mocheso o phahame ho feta 820 ° C Ho fokotseha ha thobalano le matla.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Tse ding |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2,5 | ≤0.015 | ≤0.020 | ≤0.50 |
Mechine ea tšepe ea weld:
| Ntho ea teko | Matla a tšepe Mpa | Ho hlahisa matla Mpa | Elongation % |
| Guaranteed | ≥550 | ≥360 | ≥27 |
Nako e khothalelitsoeng:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Hona joale welding (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
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.
