Kev piav qhia: J707RH yog lub electrode hydrogen uas muaj zog heev nrog cov txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive) thiab tuaj yeem vuam tau rau txhua qhov chaw. Kev ua haujlwm ntawm cov txheej txheem vuam zoo. Kev khoov txias, kev tawg thiab kev tawg ntawm cov pob qij txha vuam zoo. Cov hlau tso tawm muaj cov yas zoo thiab tawv.

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

Daim Ntawv Ceeb Toom:

1. Lub electrode yuav tsum tau ci rau 2 teev ntawm 400 ℃ ua ntej vuam ua haujlwm;

2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj nplai, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam;

3. Siv txoj kev vuam luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog.
