Tsawg Alloy Steel Vuam Electrode

J707 rh                               

GB/T E7015-G

AWS E10015-G

Nqe lus piav qhia: J707RH yog lub siab toughness ultra-low hydrogen electrode nrog qis hydrogen sodium txheej.Siv DCEP (cov khoom siv hluav taws xob ncaj qha tam sim no zoo) thiab tuaj yeem welded hauv txhua txoj haujlwm.Cov txheej txheem vuam kev ua tau zoo.Qhov txias khoov, tawg tsis kam thiab tawg tsis kam ntawm cov pob qij txha welded yog qhov zoo.Deposited hlau muaj zoo plasticity thiab toughness.

Daim ntawv thov: Nws yog siv rau vuam ntawm cov qauv hull, thiab kuj yog tsim rau vuam ntawm cov qauv tseem ceeb ntawm Rp0.2≥590MPa high-strength steel.

Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):

Mechanical zog ntawm weld hlau:

Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤4.1mL / 100g (mercury los yog gas chromatography method)

X-ray kuaj: qib kuv

Pom zoo tam sim no:

Daim ntawv ceeb toom:

1. Cov electrode yuav tsum tau ci rau 2 teev ntawm 400 ℃ 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.
