Nickel na Nickel Alloy Welding Electrode
Ni207
GB/T ENi4060
AWS A5.11 ENiCu-7
Nkọwa: Ni207 bụ Monel alloy electrode nwere obere mkpuchi sodium hydrogen.Jiri DCEP (nke dị ugbu a electrode ziri ezi) ma nwee ezigbo ịgbado ọkụ yana nguzogide mgbape.
Ngwa: Maka ịgbado ọkụ Monel ma ọ bụ ụdị nchara.Enwere ike iji ya maka oyi akwa mgbanwe ịgbado ọkụ.
Ngwakọta kemịkalụ nke igwe weld (%):
C | Mn | Fe | Si | Al | Ti | Cu | Nb | Ni | S | P |

Akwadoro ugbu a:
Dayameta mkpanaka (mm) | 3.2 | 4.0 |
Welding ugbu a (A) | 90 ~ 110 | 110 ~ 150 |
Mara:
1. The electrode ga-abụọ maka 2 hour na gburugburu 300 ℃ tupu ịgbado ọkụ ọrụ;
2. Ọ dị mkpa iji kpochaa nchara, mmanụ, mmiri na adịghị ọcha na akụkụ ịgbado ọkụ tupu ịgbado ọkụ.Gbalịa iji obere arc iji weld.
