Nickel na Nickel Alloy Welding Electrode
Ni327-4
GB / T ENi6276
AWS A5.11 ENiCrMo-4
Ibisobanuro: Ni327-4 ni electrode ishingiye kuri nikel hamwe na sodium ya hydrogène nkeya.Koresha DCEP (electrode igezwehobyiza).Ifite imikorere myiza yo gusudira hamwe na arc ihamye, gutwika gake, gukuramo byoroshye,
na weld nziza.Imiterere yubukorikori bwibyuma byabitswe birahagaze.
Gusaba: Byakoreshejwe mu gusudira karubone nkeya ya nikel-chromium-molybdenum, nka Hastelloy C276, ASTM B574, B575, B619, B622, B626, kandi irashobora no gukoreshwa mu gusudira ibyuma bidasa n’ibindi bivangwa na nikel.
Ibigize imiti yicyuma (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.02 | ≤1.0 | ≤0.2 | 14.5 ~ 16.5 | ≥50.0 | 15.0 ~ 17.0 |
| W | Co | Fe | S | P | Ibindi |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Ibikoresho bya tekinike yicyuma gisudira:
| Ikizamini | Imbaraga Mpa | Tanga imbaraga Mpa | Kurambura % |
| Bijejwe | 90690 | 00400 | ≥22 |
Icyifuzo kigezweho:
| Diameter （Mm） | 2.5 | 3.2 | 4.0 |
| Umuyoboro wo gusudira A） | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Icyitonderwa:
1. Electrode igomba gutekwa kumasaha1 hafi 300 ℃ mbere yo gusudira.Gerageza gukoresha arc ngufi kugirango usudire ；
2. Ni ngombwa guhanagura ingese, amavuta, amazi, n’umwanda ku bice byo gusudira mbere yo gusudira.
3. Gerageza gukoresha ingufu zumurongo muto mugihe cyo gusudira, ibyiciro byinshi hamwe no gusudira byinshi.
