Nickel thiab Nickel Alloy Vuam Electrode
Ni207
GB/T ENi4060
AWS A5.11 ENiCu-7
Kev piav qhia: Ni207 yog Monel alloy electrode nrog cov txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive) thiab muaj kev ua haujlwm vuam zoo thiab tiv taus tawg.
Daim Ntawv Thov: Siv rau vuam Monel lossis cov hlau sib txawv. Nws kuj tseem siv tau rau kev vuam txheej hloov pauv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| 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 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % |
| Tau lees paub | ≥480 | ≥200 | ≥27 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 3.2 | 4.0 |
| Vuam tam sim no (Ib) | 90 ~ 110 | 110 ~ 150 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 2 teev ntawm ib ncig ntawm 300 ℃ ua ntej welding ua haujlwm;
2. Ua ntej vuam, yuav tsum ntxuav cov xeb, roj, dej, thiab cov av qias neeg ntawm cov khoom vuam. Sim siv lub arc luv luv los vuam.
