I-Molybdenum ne-Chromium Molybdenum Heat Resistant SteelUkushiselaI-Electrode
R107
I-GB/T E5015-A1
I-AWS A5.5 E7015-A1
Incazelo: I-R107 iyi-electrode yensimbi ekwazi ukumelana nokushisa ene-pearlitic ene-sodium ephansi ye-hydrogen equkethe u-0.5% Mo. Sebenzisa i-DCEP (i-electrode yamanje eqondile eqondile) futhi ingashiselwa kuzo zonke izindawo. .
Isicelo: Isetshenziselwa ukushisela amapayipi obhayela anokushisa okusebenzayo okungaphansi kuka-510°C (okufana no-15Mo, njll.), futhi ingasetshenziselwa ukushisela insimbi evamile ene-alloy high-strength.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Kuqinisekisiwe | ≥490 | ≥390 | ≥22 | ≥47 |
Okuqukethwe kwe-hydrogen ye-Diffusion yensimbi efakiwe: ≤6.0mL/100g (indlela ye-glycerin)
Ukuhlolwa kwe-X-ray: I grade
Okwamanje okunconyiwe:
Ububanzi benduku (mm) | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
UkushiselaOkwamanje (A) | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Isaziso:
1. I-electrode kufanele ibhakwe ihora elingu-1 ku-350 ℃ ngaphambi kokusebenza kokushisela;
2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.
