Tsawg Kub Hlau Vuam Electrode
W 107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Nqe lus piav qhia: W107 yog qhov kub-kub steel electrode nrog qis-hydrogen sodium txheej.Siv DCEP (cov khoom siv hluav taws xob ncaj qha tam sim no) thiab tuaj yeem txuas rau txhua txoj haujlwm.Cov hlau deposited tseem muaj kev cuam tshuam zoo toughness ntawm -100 ° C.
Daim ntawv thov: Siv rau vuam tsis tshua muaj hlau xws li 3.5Ni.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Ni | S | P |
| ≤ 0.05 | ≤1.25 | ≤ 0.60 | 3.00-3.75 Nws | ≤ 0.020 | ≤ 0.025 |
Mechanical zog ntawm weld hlau:
|
Cov khoom kuaj |
Tensile zog Mpa |
Yield zog Mpa | Elongation% | Tus nqi cuam tshuam (J) -100 ℃ |
|
lav | ≥490 | ≥390 | ≥ 22 | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤4.0mL / 100g (glycerin method) los yog ≤7.0mL / 100g (mercury los yog gas chromatography method)
X-ray kuaj: qib kuv
Pom zoo tam sim no:
| (mm) Qws txoj kab uas hla | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Vuam tam sim no | 40 ~ 70 | 70 ~ 90 ib | 90-130 Nws | 140 ~ 180 ib | 180-240 ib |
Daim ntawv ceeb toom:
- Cov electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
- Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj nplai, dej, thiab impurities ntawm vuam qhov ua ntej vuam;
- Sim siv cov kab me me zog thaum vuam, ntau txheej thiab ntau dhau vuam.
