GB/T E6016-D1
AWS E9016-D1
Nqe lus piav qhia: J606 yog cov hlau tsis tshua muaj zog hlau electrode uas muaj cov poov tshuaj tsawg-hydrogen txheej.Nws tuaj yeem siv rau txhua txoj haujlwm vuam nrog AC thiab DC.Kev ua haujlwm ruaj khov ntawm AC vuam yog qis dua li ntawm DC vuam.
Daim ntawv thov: Siv rau vuam nruab nrab carbon steel thiab low-alloy high-strength steel qauv ntawm coj lub zog, xws li Q420, thiab lwm yam.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Mo | S | P |
| ≤ 0.12 | 1.25-1.75 Nws | ≤0.60 | 0.25 ~ 0.45 hli | ≤ 0.035 | ≤ 0.035 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % | Tus nqi cuam tshuam (J) -30 ℃ |
| lav | ≥590 | ≥490 | ≥15 | ≥ 27 |
| Kuaj | 620 ~ 680 ib | ≥500 | 20 ~ 28 | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤4.0mL / 100g (glycerin method)
X-ray kuaj: qib kuv
Pom zoo tam sim no:

| (A) Vuam tam sim no | 40 ~ 70 | 70 ~ 90 ib | 90 ~ 120 hli | 140 ~ 180 ib | 180-220 : kuv | 210-260 ib |
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. Siv luv arc ua haujlwm thaum vuam.Txoj kev nqaim vuam yog tsim nyog;
4. Thaum qhov vuam yog tuab, nws yuav tsum tau preheated rau saum 150 ° C thiab txias maj mam tom qab vuam.
