Nqe lus piav qhia: R406 yog pearlitic tshav kub-resistant steel electrode nrog qis-hydrogen poov tshuaj txheej uas muaj 2.5% Cr - 1% Mo.Bob AC thiab DC tuaj yeem siv tau, thiab tuaj yeem txuas rau txhua txoj haujlwm.Lub vuam yuav tsum tau preheated rau 160 ~ 200 ° C ua ntej vuam.
Daim ntawv thov: Siv rau vuam Cr2.5Mo pearlitic tshav kub-resistant steel qauv, xws li high-temperature thiab high-pressure pipelines nrog kev khiav hauj lwm kub hauv qab no 550 ° C, hluavtaws chemical machinery, thiab roj av cracking khoom.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):

Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 350 ℃ 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.
