Nickel le Nickel Alloy Welding Electrode
Ni327-6
GB/T ENi6620
AWS A5.11 ENCrMo-6
Tlhaloso: Ni327 -6 ke electrode e thehiloeng ho nickel e nang le lesela le tlaase la hydrogen sodium.Sebelisa DCEP (electrode ea hona joale e tobilengntle).Tšepe e kentsoeng e na le polasetiki e ntle haholo, e thata le e hanyetsanang le crack.Tšepe e kentsoeng e na le coefficient ea katoloso e tšoanang le ea tšepe, 'me e na le matla a phahameng le khanyetso e matla ea kutu mochesong oa kamore le mocheso o phahameng.
Kopo: E sebelisoa bakeng sa ho cheselletsa tšepe ea Ni9%, hape e ka sebelisoa bakeng sa ho cheselletsa litšepe tse sa tšoaneng le li-alloys tse thata ho tjheseletsa.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Tse ding |

Mechine ea tšepe ea weld:
| Ntho ea teko | Matla a tšepe Mpa | Ho hlahisa matla Mpa | Elongation % |
| Guaranteed | ≥620 | ≥350 | ≥32 |
Nako e khothalelitsoeng:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 |
| Hona joale welding (A) | Lilemo tse 50-70 | 80 ~ 100 | 110 ~ 150 |
Tlhokomeliso:
1. Electrode e tlameha ho behoa hora e le 1 ho pota 300 ℃ pele ho ts'ebetso ea welding.Leka ho sebelisa arc e khuts'oane ho cheselletsa;
2. Ke habohlokoa hore u hloekise mafome, oli, metsi le litšila holim'a likarolo tsa ho cheseletsa pele u cheselletsa.
3. Leka ho sebelisa matla a mohala o monyane ha ho tjheseletsa, ho etsa li-multi-layer le multi-pass welding.
