Nickel da Nickel Alloy Welding Electrode
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Bayani: Ni307-2 na'urar lantarki ne na tushen nickel tare da ƙarancin sodium mai ƙarancin hydrogen.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye).Tun da waldi ya ƙunshi adadin molybdenum, niobium da sauran abubuwa masu haɗawa, ƙarfe da aka ajiye yana da kyakkyawan juriya.
Aikace-aikace: Ana amfani da waldi na nickel-chromium-iron gami (kamar UNS N08800, UNS N06600), musamman dace da waldi na dissimilar karafa, mika mulki Layer waldi da surfacing waldi, kuma za a iya amfani da lokacin da aiki zafin jiki ne 980 ° C. amma zai iya tsayayya da hadawan abu da iskar shaka lokacin da zafin jiki ya fi 820 ° C Rage jima'i da tsanani.
Abubuwan sinadaran na weld karfe(%):
| 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 | Sauran |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Abubuwan kayan aikin walda:
| Gwaji abu | Ƙarfin ƙarfi Mpa | Ƙarfin bayarwa Mpa | Tsawaitawa % |
| Garanti | ≥550 | ≥360 | ≥27 |
Shawarwari na yanzu:
| Diamita na sanda (mm) da | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding halin yanzu (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Sanarwa:
1. A lantarki dole ne a gasa for1 hour a kusa da 300 ℃ kafin walda aiki;
2. Yana da mahimmanci a tsaftace tsatsa, mai, ruwa, da datti akan sassan walda kafin walda.Gwada amfani da gajeriyar baka don walda.
