Na'urar Walda ta Nickel da Nickel Alloy
Ni207
GB/T ENi4060
AWS A5.11 ENiCu-7
Bayani: Ni207 wani lantarki ne mai suna Monel alloy electrode wanda ke da ƙarancin sinadarin hydrogen sodium. Yi amfani da DCEP (mai nuna wutar lantarki kai tsaye) kuma yana da kyakkyawan aikin walda da juriya ga tsagewa.
Aikace-aikace: Don walda Monel ko ƙarfe daban-daban. Hakanan ana iya amfani da shi don shimfida layin canzawa na walda.
Sinadarin sinadarai na ƙarfen walda(%):
| C | Mn | Fe | Si | Al | Ti | Cu | Nb | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≤2.5 | ≥62.0 | ≤0.015 | ≤0.020 |
Kayan aikin injiniya na ƙarfe na walda:
| Gwaji abu | Ƙarfin tauri Mpa | Ƙarfin bayarwa Mpa | Ƙarawa % |
| An Garanti | ≥480 | ≥200 | ≥27 |
Shawarar da ake bayarwa:
| Diamita na sanda (mm) | 3.2 | 4.0 |
| Walda na yanzu (A) | 90 ~ 110 | 110 ~ 150 |
Sanarwa:
1. Dole ne a gasa wutar lantarki na tsawon awa 2 a kusan 300℃ kafin a fara aikin walda;
2. Yana da mahimmanci a tsaftace tsatsa, mai, ruwa, da ƙazanta a kan sassan walda kafin a yi walda. Yi ƙoƙarin amfani da ɗan gajeren baka don walda.
