Nickel thiab Nickel Alloy Vuam Electrode
N307-1
GB/T ENi6062
AWS A5.11 ENiCrFe-1
Nqe lus piav qhia: Ni307-1 yog nickel-based electrode nrog qis hydrogen sodium txheej.Siv DCEP (direct tam sim no electrode zoo).Txij li thaum lub weld muaj Nb, cov hlau deposited muaj zoo plasticity thiab tawg kuj.
Daim ntawv thov: Siv rau vuam nickel-chromium-hlau alloys (xws li UNS N06600, UNS N06601) thiab surfacing ntawm hlau.Nws muaj qhov sib txawv ntawm cov hlau vuam zoo.Nws kuj tseem tuaj yeem siv rau ntawm qhov ua haujlwm kub ntawm 980 ° C, tab sis thaum qhov kub siab tshaj 820 ° C, oxidation kuj thiab lub zog yuav txo.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| 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 Nws | 0.5 ~ 4.0 | ≤ 0.015 | ≤ 0.020 | ≤0.50 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
| lav | ≥550 | ≥360 | ≥ 27 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no (A) | 60 ~ 90 | 80 ~ 110 ib | 110 ~ 150 ib | 130 ~ 180 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 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.
