I-Molybdenum ne-Chromium Molybdenum Heat Resistant Steel Welding Electrode
R106
I-GB/T E5016-A1
I-AWS A5.5 E7016-A1
Incazelo: I-R106 iyi-electrode yensimbi ekwazi ukumelana nokushisa i-pearlitic ene-low-hydrogen potassium coating equkethe u-0.5% Mo. Ingasetshenziselwa ukushisela yonke indawo nge-AC ne-DC.I-weldment kufanele ishiswe ngaphambili ibe ngu-90 ~ 110 ℃ ngaphambi kokushisela.
Isicelo: Isetshenziselwa ukushisela amapayipi okushisa okusebenzayo okungaphansi kuka-510 ° C, njengamapayipi angu-15Mo, AST-MA204 kanye ne-A335-P1, njll.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
C | Mn | Si | Mo | S | P |
≤0.12 | ≤0.60 | ≤0.40 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
Izici zemishini ye-weld metal:
Into yokuhlola | Amandla aqinile Mpa | Amandla esivuno Mpa | Ukwelula % | Inani lomthelela (J) ITemp Ejwayelekile. |
Kuqinisekisiwe | ≥490 | ≥390 | ≥20 | - |
Ihloliwe | 530 | 420 | 27 | 60 |
Ukuhlolwa kwe-X-ray: I grade
Okwamanje okunconyiwe:
Ububanzi benduku (mm) | 2.5 | 3.2 | 4.0 | |
I-Welding Yamanje (A) | Ukushisela okuphansi | 80 ~ 110 | 110 ~ 140 | 170 ~ 200 |
Ukushisela okuqondile, Ukushisela ngaphezulu | 70 ~ 90 | 100 ~ 120 | 140 ~ 170 |
Isaziso:
1. I-electrode kufanele ibhakwe ihora elingu-1 ku-150 ~ 200 ℃ ngaphambi kokusebenza kokushisela;
2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.
