I-Low Temperature Steel Welding Electrode
W107
I-GB/T E5015-C2L
I-AWS A5.5 E7015-C2L
Incazelo: I-W107 iyi-electrode yensimbi enezinga lokushisa eliphansi ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondile) futhi ingashiselelwa kuzo zonke izikhundla.Insimbi ediphozithiwe isenokuqina okuhle komthelela ku -100°C.
Isicelo: Isetshenziselwa ukushisela insimbi yokushisa ephansi efana ne-3.5Ni.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Izici zemishini ye-weld metal:
|
Into yokuhlola |
Amandla aqinile Mpa |
Amandla esivuno Mpa | Elongation% | Inani lomthelela (J)-100℃ |
|
Kuqinisekisiwe | ≥490 | ≥390 | ≥22 | ≥27 |
Okuqukethwe kwe-hydrogen yokusabalalisa kwensimbi efakiwe: ≤4.0mL/100g (indlela ye-glycerin) noma ≤7.0mL/100g (indlela ye-mercury noma yegesi chromatography)
Ukuhlolwa kwe-X-ray: I grade
Okwamanje okunconyiwe:
| (mm) Ububanzi benduku | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) I-Welding Yamanje | 40 ~ 70 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
Isaziso:
- I-electrode kufanele ibhakwe ihora elingu-1 ku-350 ℃ ngaphambi kokusebenza kokushisela;
- Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela;
- Zama ukusebenzisa amandla kalayini omncane lapho ushisela, ungqimba oluningi kanye ne-multi-pass welding.
