Kev piav qhia: R306Fe yog lub electrode hlau pearlitic uas tiv taus cua sov nrog hmoov hlau thiab cov tshuaj hydrogen potassium tsawg uas muaj 1% Cr - 0.5% Mo. Ob qho tib si AC thiab DC tuaj yeem siv, thiab tuaj yeem vuam rau txhua qhov chaw nrog kev ua haujlwm luv luv. Qhov preheating ntawm qhov vuam thiab qhov kub ntawm interlayer yog 160 ~ 250 ° C thaum vuam.

Daim Ntawv Thov: Siv rau kev vuam ntawm 1% Cr - 0.5% Mo pearlitic cua sov-resistant hlau (xws li 15CrMo), xws li boiler cua sov nto kav dej nrog ua haujlwm kub hauv qab 550 ° C, chav kav dej thiab siab hlab ntsha nrog ua haujlwm kub hauv qab 520 ° C, thiab lwm yam. Nws tuaj yeem siv rau kev vuam ntawm 30CrMnSi steel castings.

Daim Ntawv Ceeb Toom:

1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 350 ℃ ua ntej welding ua haujlwm;

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