I-Nickel kunye ne-Nickel Alloy Welding Electrode
Ni327-6
GB/T ENi6620
I-AWS A5.11 ENiCrMo-6
Inkcazo: I-Ni327 -6 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.Isinyithi esibekiweyo sinomgca wokwandiswa kwe-coefficient efana naleyo yentsimbi, kwaye inamandla aphezulu kunye nokuxhathisa okuqinileyo kwi-corrosion kwiqondo lokushisa kunye nobushushu obuphezulu.
Isicelo: Isetyenziselwa ukuwelda kwentsimbi ye-Ni9%, kwaye ingasetyenziselwa ukuwelda kweentsimbi ezingafaniyo kunye ne-alloys enzima uku-weld.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Okunye |
|
| 0.5 ~ 2.0 | 1.0 ~ 2.0 | 12.0 ~ 17.0 | ≤0.015 | ≤0.020 | ≤0.5 |
|
Iimpawu zobuchwephesha bentsimbi ye-weld:
| Into yovavanyo | Tensile strength Mpa | Unikeze Amandla Mpa | Elongation % |
| Iqinisekisiwe | ≥620 | ≥350 | ≥32 |
yangoku eCetyisiweyo:
| Intonga yobubanzi (mm) | 2.5 | 3.2 | 4.0 |
| Welding okwangoku (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Isaziso:
1. I-electrode kufuneka ibhakwe iyure enye malunga ne-300 ℃ phambi kokusebenza kwe-welding.Zama ukusebenzisa i-arc emfutshane ukuwelda;
2. Kubalulekile ukucoca umhlwa, i-oyile, amanzi, nokungcola kwiindawo zokuwelda phambi kokuba udiye.
3. Zama ukusebenzisa amandla omgca omncinci xa udibanisa, i-multi-layer kunye ne-multi-pass welding.
