Nickel na Nickel Alloy Welding Electrode
Ni307-7
GB / T ENi6152
AWS A5.11 ENiCrFe-7
Ibisobanuro: Ni307-7 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.Icyuma cyabitswe gifite imiterere ihamye kandi irwanya ruswa muriubushyuhe bwo hejuru bwa okiside hamwe nikirere kirimo sulfure.
Gushyira mu bikorwa: Byakoreshejwe mu buhanga bwa kirimbuzi, aside sulfurike, aside nitricike n’ibikoresho byo gukora fluor ya hydrogène, nka nikel 690 alloy, ASTM B166, B167, b168, nibindi, birashobora kandi gukoreshwa mugusudira nikel-chromium ibyuma nicyuma kitagaragara kandi cyangirika. -ibice bitarwanya ibyuma.
Ibigize imiti yicyuma (%):
| C | Mn | Fe | Si | Ni | Cr |
| ≤0.05 | ≤5.0 | 7.0 ~ 12.0 | ≤0.8 | ≥50.0 | 28.0 ~ 31.5 |
| Cu | Mo | Nb | S | P | Ibindi |
| ≤0.5 | ≤0.5 | 1.0 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.5 |
Ibikoresho bya tekinike yicyuma gisudira:
| Ikizamini | Imbaraga Mpa | Tanga imbaraga Mpa | Kurambura % |
| Bijejwe | 50550 | 60360 | ≥27 |
Icyifuzo kigezweho:
| Diameter （Mm） | 2.5 | 3.2 | 4.0 |
| Umuyoboro wo gusudira A） | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 |
Icyitonderwa:
1. Electrode igomba gutekwa kumasaha1 hafi 300 ℃ mbere yo gusudira;
2. Ni ngombwa guhanagura ingese, amavuta, amazi, n’umwanda ku bice byo gusudira mbere yo gusudira.Gerageza gukoresha arc ngufi kugirango usudire.
