Nickel na Nickel Alloy Welding Electrode
Ni307-2
GB / T ENi6133
AWS A5.11ENiCrFe-2
Ibisobanuro: Ni307-2 ni electrode ishingiye kuri nikel hamwe na sodium ya hydrogène nkeya.Koresha DCEP (itaziguye ya electrode nziza).Kubera ko gusudira birimo urugero rwa molybdenum, niobium nibindi bintu bivanga, ibyuma byabitswe bifite imbaraga zo guhangana.
Gusaba: Byakoreshejwe mu gusudira nikel-chromium-fer (nka UNS N08800, UNS N06600), cyane cyane ibereye gusudira ibyuma bidasa, gusudira ibice byinzibacyuho no gusudira hejuru, kandi birashobora no gukoreshwa mugihe ubushyuhe bwakazi ari 980 ° C, ariko irashobora kurwanya okiside mugihe ubushyuhe buri hejuru ya 820 ° C Kugabanuka kwimibonano nimbaraga.
Ibigize imiti yicyuma (%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Ibindi |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
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 | 5.0 |
| Umuyoboro wo gusudira A） | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
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.
