Nickel et Nickel Alloy Welding Electrode
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Descriptio: Ni307-2 est electrode nickel substructio cum sodium humili-hydrogenis efficiens.Utere DCEP (electrode current directum positivum).Cum pugillo molybdaeni, niobium et alia mixtura quaedam elementa contineat, metallum depositum bene rima resistit.
Applicatio: Usus ad mixturas mixturae nickel-chromium-ferreas (ut UNS N08800, UNS N06600), praesertim apta ad glutino metallorum dissimilium, strato glutino et surfacing glutino transitus, ac etiam adhiberi potest cum temperatura laborantis 980 ° C; sed potest oxidatio resistere, quando siccus est altior quam 820 ° C sexui decrescente et intensio.
Compositio chemica metallici solidi (%):
| 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 | Other |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Mechanica metallorum congeries;
| Test item | Distrahentes fortitudo Mpa | Cedat imperium Mpa | Prolongatio % |
| guaranteed | ≥550 | ≥360 | ≥27 |
Commendatur current:
| Rod diam mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding current A） | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Animadverte:
1. Electrodum coquendum est hora 1 circiter 300℃ ante operationem glutinum;
2. Essentiale est purgare ferruginem, oleum, aquam, et immunditias in partibus glutino ante glutino.Conare brevi arcum pactionem utere.
