Nickel na Nickel Alloy Welding Electrode
Ni327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
Nkọwa: Ni327 -6 bụ electrode dabeere na nickel nke nwere mkpuchi sodium dị ala.Jiri DCEP (electrode ugbu a kpọmkwemnti).Igwe a na-echekwara nwere ezigbo plasticity, ike na mgbape mgbape.Igwe a na-etinye ego nwere ọnụọgụ mgbasawanye ahịrị dịka nke ígwè, ma nwee ike dị elu na nguzogide corrosion siri ike na ọnụ ụlọ okpomọkụ na oke okpomọkụ.
Ngwa: A na-eji ya maka ịgbado ọkụ nke Ni9% ígwè, a pụkwara iji ya mee ihe maka ịgbado ígwè dị iche iche na alloys siri ike na-agbado.
Ngwakọta kemịkalụ nke igwe 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 | Ndị ọzọ |

Njirimara nke igwe weld metal:
| Nwalee ihe | Ike ọdụdọ Mpa | Mpụta ike Mpa | Ogologo oge % |
| Ekwenyere | ≥620 | ≥350 | ≥32 |
Akwadoro ugbu a:
| Dayameta mkpanaka (mm) | 2.5 | 3.2 | 4.0 |
| Welding ugbu a (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Mara:
1. The electrode ga-abụọ maka 1 hour na gburugburu 300 ℃ tupu ịgbado ọkụ ọrụ.Gbalịa iji obere arc iji weld;
2. Ọ dị mkpa iji kpochaa nchara, mmanụ, mmiri na adịghị ọcha na akụkụ ịgbado ọkụ tupu ịgbado ọkụ.
3. Gbalịa iji obere ike akara mgbe ịgbado ọkụ, multi-layer na multi-pass ịgbado ọkụ.
