Nickel thiab Nickel Alloy Vuam Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Kev piav qhia: Ni202 yog Ni70Cu30 Monel alloy electrode nrog titanium calcium txheej. Nws tuaj yeem siv rau ob qho tib si AC thiab DC. Cov hlau tso tawm muaj kev tiv thaiv kev tawg zoo vim muaj cov ntsiab lus tsim nyog ntawm manganese thiab niobium. Nws muaj kev ua haujlwm vuam zoo heev nrog kev kub hnyiab ruaj khov, tsawg dua spatter, yooj yim tshem tawm slag, thiab zoo nkauj weld.
Daim Ntawv Thov: Nws yog siv rau kev vuam ntawm cov hlau nickel-tooj liab thiab cov hlau sib txawv, thiab kuj tseem siv tau ua cov khoom siv hloov pauv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| 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 |
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) | 2.5 | 3.2 | 4.0 |
| Vuam tam sim no (Ib) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 250 ℃ ua ntej welding ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam.
