Tsawg Alloy Steel Vuam Electrode
j557 ua
GB/T E5515-G
AWS E8015-G
Nqe lus piav qhia: J557 yog cov hlau tsis tshua muaj hlau 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.
Daim ntawv thov: Siv rau vuam nruab nrab carbon steel thiab qis alloy steel qauv xws li Q390.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | S | P |
| ≤ 0.12 | ≥1.00 Nws | 0.30-0.70 Nws | ≤ 0.035 | ≤ 0.035 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % | Tus nqi cuam tshuam (J) | |
| -20 ℃ | -30 ℃ | ||||
| lav | ≥540 | ≥440 | ≥17 | — | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤6.0mL / 100g (glycerin method)
X-ray kuaj: qib kuv
Pom zoo tam sim no:
| (mm) Qws txoj kab uas hla | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Vuam tam sim no | 60 ~ 90 | 80 ~ 110 ib | 130-170 ib | 160-200 Nws |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig 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. Siv luv arc ua haujlwm thaum vuam.Txoj kev nqaim welding yog tsim nyog.
