Nickel thiab Nickel Alloy Vuam Electrode
Ni307-1
GB/T ENi6062
AWS A5.11 ENiCrFe-1
Kev piav qhia: Ni307-1 yog ib lub electrode uas muaj nickel nrog cov txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive). Vim tias qhov weld muaj Nb, cov hlau uas tau tso rau hauv muaj cov yas zoo thiab tiv taus kev tawg.
Daim Ntawv Thov: Siv rau kev vuam cov hlau nickel-chromium-iron (xws li UNS N06600, UNS N06601) thiab kev ua kom cov hlau saum npoo. Muaj cov yam ntxwv zoo sib xws ntawm kev vuam hlau. Nws kuj tseem siv tau ntawm qhov kub ua haujlwm ntawm 980 ° C, tab sis thaum qhov kub siab dua 820 ° C, qhov kev tiv thaiv oxidation thiab lub zog yuav txo qis.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Fe | Si | Cu | Ni | Cr | Nb + Ta | S | P | Lwm yam |
| ≤0.08 | ≤3.5 | ≤11.0 | ≤0.8 | ≤0.5 | ≥62.0 | 13.0 ~ 17.0 | 0.5 ~ 4.0 | ≤0.015 | ≤0.020 | ≤0.50 |
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 | ≥550 | ≥360 | ≥27 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no (Ib) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 | 130 ~ 180 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 300 ℃ ua ntej vuam 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.
