Nickel uye Nickel Alloy Welding Electrode
Ni307-3
GB/T ENi6182
AWS A5.11 ENCrFe-3
Tsanangudzo: Ni307-3 is anickel-based electrode ine yakaderera-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka).Iyo ine yakanaka kutsemuka kuramba nekuti weld ine yakati wandei manganese, niobium, uye zvimwe zvinosanganiswa zvinhu.
Chikumbiro: Inoshandiswa kugadzira welding yenickel-chromium-iron alloys (senge UNS N06600) uye pamusoro pesimbi.Tembiricha yekushanda kazhinji haina kukwira kupfuura 480 ° C, uye kuramba kwekupwanya kwakanaka.Inokodzera atomic choto chinomanikidza mudziyo uye kemikari tank welding.
Kemikari yakagadzirwa nesimbi weld (%):
C | Mn | Fe | P | S | Si | Cu |
≤0.10 | 5.0 ~ 10.0 | ≤10.0 | ≤0.020 | ≤0.015 | ≤1.0 | ≤0.5 |
Ni | Ti | Mo | Nb | Ta | Zvimwe |
|
≥60.0 | ≤1.0 | 13.0 ~ 17.0 | 1.0 ~ 3.5 | ≤0.30 | ≤0.50 |
|
Mechanical zvimiro zve weld simbi:
Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % |
Guaranteed | ≥550 | ≥360 | ≥27 |
Yazvino inokurudzirwa:
Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
Welding ikozvino (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Cherechedza:
1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 300 ℃ isati yaitwa welding;
2. Zvakakosha kuchenesa dzine ngura, oiri, mvura, uye tsvina pazvikamu zvinonamatwa tisati tapisa.Edza kushandisa arc pfupi kuti weld.
