Kev piav qhia: R107 yog lub electrode hlau pearlitic uas tiv taus cua sov nrog lub txheej sodium hydrogen tsawg uas muaj 0.5% Mo. Siv DCEP (direct current electrode positive) thiab tuaj yeem welded rau txhua qhov chaw. Lub weldment yuav tsum tau preheated rau 90 ~ 110 ℃ ua ntej welding.

Daim Ntawv Thov: Nws yog siv rau kev vuam cov kav dej boiler nrog qhov kub ua haujlwm qis dua 510 ° C (xws li 15Mo, thiab lwm yam), thiab tseem tuaj yeem siv rau kev vuam cov hlau tsis tshua muaj zog.

Daim Ntawv Ceeb Toom:

1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam 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.
