Tsawg Kub Hlau Vuam Electrode
wb 707
GB/T E5015-G
AWS A5.5 E7015-G
Nqe lus piav qhia: W707 yog qhov kub thiab txias steel electrode nrog cov txheej txheem hydrogen sodium tsawg.Siv DCEP (cov khoom siv hluav taws xob ncaj qha tam sim no) thiab tuaj yeem txuas rau txhua txoj haujlwm.Cov hlau tso tawm tseem muaj qhov cuam tshuam zoo ntawm -70 ° C.
Daim ntawv thov: Siv rau vuam tsis tshua muaj hlau xws li 2.5Ni.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Ni | S | P |
| ≤ 0.08 | ≤1.25 | ≤ 0.60 | 2.00-2.75 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) -70 ℃ |
| 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 | 70 ~ 100 | 90 ~ 120 hli | 140 ~ 180 ib | 170-210 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
2. Sim siv cov kab hluav taws xob me me thaum vuam, ntau txheej thiab ntau dhau vuam.
