I-Nickel kunye ne-Nickel AlloyUkuweldaI-Electrode
Ni327-3
GB/T ENi6625
Inkcazo: I-Ni327 -3 yi-electrode esekelwe kwi-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yangoku ngqopositive).Intsimbi egciniweyo ineplastiki egqwesileyo, ukuqina kunye nokumelana nokuqhekeka, kwaye inamandla aphezulu kunye nokuxhathisa okuqinileyo kwe-corrosion kwiqondo lobushushu begumbi kunye nobushushu obuphezulu.
Isicelo: Isetyenziselwa ukuwelda kwe-nickel-chromium-molybdenum alloys, ngakumbi ukuwelda kunye nokujonga phezulu kwe-UNS N06625 alloys kunye nezinye iintlobo zentsimbi kunye ne-nickel-chromium-molybdenum ialloy alloy alloys, kwaye ingasetyenziselwa ukuwelda i-Ni9% yentsimbi phantsi. iimeko zobushushu obuphantsi.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.10 | ≤2.0 | ≤0.8 | 20.0 ~ 23.0 | ≥55.0 | 8.0 ~ 10.0 |
| Fe | Cu | Nb + Ta | S | P | Okunye |
| ≤7.0 | ≤0.5 | 3.0 ~ 4.2 | ≤0.015 | ≤0.020 | ≤0.5 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
| Into yovavanyo | Tensile strength Mpa | Unikeze Amandla Mpa | Elongation % |
| Iqinisekisiwe | ≥760 | ≥420 | ≥27 |
yangoku eCetyisiweyo:
| Intonga yobubanzi (mm) | 2.5 | 3.2 | 4.0 |
| Ukuweldayangoku (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Isaziso:
- I-electrode kufuneka ibhakwe iyure enye malunga ne-300 ℃ phambi kokusebenza kwe-welding.Zama ukusebenzisa i-arc emfutshane ukuwelda;
- Kubalulekile ukucoca umhlwa, i-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udiye.
3. Zama ukusebenzisa amandla omgca omncinci xa udibanisa, i-multi-layer kunye ne-multi-pass welding.
