I-Electrode yokuWelda yeNickel kunye neNickel Alloy
I-Ni202
GB/T ENi4060
I-AWS A5.11 ENiCu-7
Inkcazo: I-Ni202 yi-electrode ye-alloy ye-Ni70Cu30 Monel ene-titanium calcium coating. Ingasetyenziselwa zombini i-AC kunye ne-DC. Isinyithi esigciniweyo sinokumelana okuhle nokuqhekeka ngenxa yomxholo ofanelekileyo we-manganese kunye ne-niobium. Isebenza kakuhle kakhulu ekudibaniseni kunye nokutsha okuzinzileyo kwe-arc, ukuchitheka kancinci, ukususa i-slag ngokulula, kunye ne-weld entle.
Ukusetyenziswa: Isetyenziselwa ukuwelda i-alloy ye-nickel-copper kunye nentsimbi eyahlukileyo, kwaye ingasetyenziswa njengezinto ezisetyenziswa njenge-transitional overlay material.
Ukwakheka kweekhemikhali zesinyithi esijiyiweyo (%):
| C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥62.0 | ≤0.015 | ≤0.020 |
Iimpawu zoomatshini zesinyithi esijijekileyo:
| Into yovavanyo | Tensile strength I-Mpa | Unikeze Amandla I-Mpa | Ukwandiswa % |
| Iqinisekisiwe | ≥480 | ≥200 | ≥27 |
I-current ecetyiswayo:
| Ububanzi bentonga （mm） | 2.5 | 3.2 | 4.0 |
| Ukuwelda komsinga (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Isaziso:
1. I-electrode mayibhakwe iyure e-1 malunga nama-250℃ ngaphambi kokuba isebenze nge-welding;
2. Kubalulekile ukucoca umhlwa, ioyile, amanzi kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba uwelda.
