Molybdenum thiab Chromium Molybdenum Thaum tshav kub kub Resistant Steel Vuam Electrode
R106
GB/T E5016-A1
AWS A5.5 E7016-A1
Nqe lus piav qhia: R106 yog pearlitic tshav kub-resistant steel electrode nrog qis-hydrogen potassium txheej uas muaj 0.5% Mo. Nws tuaj yeem siv rau txhua txoj haujlwm vuam nrog AC thiab DC.Lub vuam yuav tsum tau preheated rau 90 ~ 110 ℃ ua ntej vuam.
Daim ntawv thov: Nws yog siv rau vuam boiler kav nrog ua hauj lwm kub hauv qab 510 ° C, xws li 15Mo, AST-MA204 thiab A335-P1 kav, thiab lwm yam. Nws kuj yuav siv tau rau welding general low-alloy high-strength steels.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):

X-ray kuaj: qib kuv
Pom zoo tam sim no:
| Txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 | |
| Vuam tam sim no (A) | Vuam tiaj | 80 ~ 110 ib | 110 ~ 140 ib | 170-200 Nws |
| Vertical vuam, Overhead welding | 70 ~ 90 ib | 100 ~ 120 | 140-170 ib | |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm 150 ~ 200 ℃ 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.
