I-Alloy ephantsi ye-Steel Welding Electrode
J707
I-GB/T E7015-D2
AWS E10015-D2
Inkcazo: I-J707 yi-alloy ephantsi ye-electrode yensimbi ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode echanekileyo yangoku), kwaye inokudityaniswa kuzo zonke izikhundla.Xa kuyimfuneko, i-weldments inokufudumeza ngaphambi kokuba i-welding kwaye iqhutywe emva kwe-welding.
Isicelo: Isetyenziselwa kakhulu i-welding 15MnMoV, 14MnMoVB, 18MnMoNb kunye nezinye izakhiwo zentsimbi ephantsi.Ulwakhiwo oludityanisiweyo lunokusebenza phantsi kwemeko ye-welding okanye yokufudumala (500 ~ 650 ℃).
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| C | Mn | Si | Mo | S | P |
Iqinisekisiwe | ≤0.15 | 1.65 ~ 2.00 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.040 |
Ivavanyiwe | 0.073 | 1.68 | 0.54 | 0.40 | 0.011 | 0.018 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
Into yovavanyo | Tensile strength Mpa | Unikeze Amandla Mpa | Elongation % | Ixabiso lempembelelo (J) -30℃ |
Iqinisekisiwe | ≥690 | ≥590 | ≥15 | ≥27 |
Ivavanyiwe | 720 | 610 | 18.6 | - |
Ukusasazwa kwe-hydrogen umxholo wentsimbi egciniweyo: ≤4.0mL/100g (indlela yeglycerin)
Ukuhlolwa kwe-X-reyi: I grade
yangoku eCetyisiweyo:
(mm) Intonga yobubanzi | 2.5 | 3.2 | 4.0 | 5.0 |
(A) I-Welding yangoku | 60 ~ 100 | 100 ~ 140 | 140 ~ 190 | 190 ~ 250 |
Isaziso:
1. I-electrode kufuneka ibhakwe ngeyure eli-1 kwi-350 ~ 380 ℃ ngaphambi kokusebenza kwe-welding;
2. Kubalulekile ukucoca umhlwa, isikali se-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udibanise;
3. Sebenzisa umsebenzi omfutshane we-arc xa udibanisa.Umzila we-welding emxinwa ufanelekile.
