Nickel thiab Nickel Alloy Vuam Electrode
Ni 207
GB/T ENi4060
AWS A5.11 ENiCu-7
Nqe lus piav qhia: Ni207 yog Monel alloy electrode nrog qis hydrogen sodium txheej.Siv DCEP (cov khoom siv hluav taws xob ncaj qha tam sim no zoo) thiab muaj kev ua haujlwm zoo vuam thiab tawg tsis kam.
Daim ntawv thov: Rau vuam Monel lossis cov hlau tsis sib xws.Nws kuj tseem siv tau rau overlay vuam kev hloov txheej.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| 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 Nws | ≤ 2.5 | ≥62.0 | ≤ 0.015 | ≤ 0.020 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
| lav | ≥480 | ≥200 | ≥ 27 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 3.2 | 4.0 |
| Vuam tam sim no (A) | 90 ~ 110 ib | 110 ~ 150 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 2 teev ntawm ib ncig ntawm 300 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam.Sim siv luv luv arc rau vuam.
