Tsawg Kub Hlau Vuam Electrode
wb 607
GB/T E5015-G
AWS A5.5 E7015-G
Nqe lus piav qhia: W607 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 muaj kev cuam tshuam zoo toughness ntawm -60 ° C.
Daim ntawv thov: Siv rau vuam tsis tshua muaj steel hlau xws li 09MnD.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Ni | S | P |
| ≤ 0.08 | ≤1.65 | ≤ 0.60 | 0.50 ~ 2.50 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) -60 ℃ |
| lav | ≥490 | ≥390 | ≥ 22 | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤6.0mL / 100g (glycerin method) los yog ≤10mL / 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 | 60 ~ 90 | 100 ~ 120 | 140-170 ib | 170-200 Nws |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj nplai, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam;
3. Lub welded ib feem tuaj yeem preheated ntawm li 150 ° C ua ntej vuam los tiv thaiv kev tawg.
