I-Nickel kunye ne-Nickel Alloy Welding Electrode
Ni307-2
GB/T ENi6133
AWS A5.11I-ENiCrFe-2
Inkcazo: I-Ni307-2 yi-electrode esekelwe kwi-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yangoku echanekileyo).Ekubeni i-weld iqulethe inani elithile le-molybdenum, i-niobium kunye nezinye izinto ezixutywayo, isinyithi esidipozithiweyo sinokuxhathisa okulungileyo kokuqhekeka.
Isicelo: Isetyenziselwa ukuwelda i-nickel-chromium-iron alloys (efana ne-UNS N08800, UNS N06600), ilungele ngokukodwa ukuwelda isinyithi esingafaniyo, i-welding yenguqu yomaleko kunye ne-welding engaphezulu, kwaye ingasetyenziswa xa ubushushu bokusebenza bungama-980 ° C, kodwa inokumelana ne-oxidation xa iqondo lobushushu lingaphezulu kwe-820 ° C Ukuncipha kwesondo kunye nokuqina.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Okunye |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
| Into yovavanyo | Tensile strength Mpa | Unikeze Amandla Mpa | Elongation % |
| Iqinisekisiwe | ≥550 | ≥360 | ≥27 |
yangoku eCetyisiweyo:
| Intonga yobubanzi (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding okwangoku (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Isaziso:
1. I-electrode kufuneka ibhakwe ngeyure enye malunga ne-300 ℃ phambi kokusebenza kwe-welding;
2. Kubalulekile ukucoca umhlwa, i-oyile, amanzi, nokungcola kwiindawo zokuwelda phambi kokuba udiye.Zama ukusebenzisa i-arc emfutshane ukuwelda.
