Nickel na Nickel Alloy Welding Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Nkọwa: Ni202 bụ Ni70Cu30 Monel alloy electrode na titanium calcium coating.Ọ nwere ike iji ma AC na DC.Igwe a na-echekwara nwere ezigbo nguzogide mgbape n'ihi ọdịnaya kwesịrị ekwesị nke manganese na niobium.Ọ na-arụ ọrụ ịgbado ọkụ nke ọma yana ọkụ arc kwụsiri ike, obere spatter, iwepu slag dị mfe, yana weld mara mma.
Ngwa: A na-eji ya maka ịgbado ọkụ nke nickel-copper alloy na ígwè dị iche iche, a pụkwara iji ya mee ihe dị ka ihe mkpuchi mgbanwe.
Ngwakọta kemịkalụ nke igwe weld (%):
| C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥62.0 | ≤0.015 | ≤0.020 |
Njirimara nke igwe weld metal:
| Nwalee ihe | Ike ọdụdọ Mpa | Mpụta ike Mpa | Ogologo oge % |
| Ekwenyere | ≥480 | ≥200 | ≥27 |
Akwadoro ugbu a:
| Dayameta mkpanaka (mm) | 2.5 | 3.2 | 4.0 |
| Welding ugbu a (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Mara:
1. The electrode ga-abụọ maka 1 hour na gburugburu 250 ℃ tupu ịgbado ọkụ ọrụ;
2. Ọ dị mkpa iji kpochaa nchara, mmanụ, mmiri na adịghị ọcha na akụkụ ịgbado ọkụ tupu ịgbado ọkụ.
