GB/T ENi6625
Apejuwe: Ni327 -3 jẹ elekiturodu ti o da lori nickel pẹlu ideri iṣuu soda kekere-hydrogen.Lo DCEP (elekiturodu lọwọlọwọ taararere).Irin ti a fi silẹ ni ṣiṣu ti o dara julọ, lile ati ijakadi ijakadi, ati pe o ni agbara giga ati ipata ipata ni iwọn otutu yara ati iwọn otutu giga.
Ohun elo: O ti wa ni lilo fun awọn alurinmorin ti nickel-chromium-molybdenum alloys, paapa awọn alurinmorin ati surfacing ti UNS N06625 alloys ati awọn miiran irin iru ati nickel-chromium-molybdenum alloy alloy steels, ati ki o tun le ṣee lo fun alurinmorin Ni9% irin labẹ kekere otutu ipo.
Apapọ kemikali ti irin weld (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.10 | ≤2.0 | ≤0.8 | 20.0 ~ 23.0 | ≥55.0 | 8.0 ~ 10.0 |
| Fe | Cu | Nb + Ta | S | P | Omiiran |
| ≤7.0 | ≤0.5 | 3.0 ~ 4.2 | ≤0.015 | ≤0.020 | ≤0.5 |
Awọn ohun-ini ẹrọ ti irin weld:
| Ohun elo idanwo | Agbara fifẹ Mpa | Agbara ikore Mpa | Ilọsiwaju % |
| Ẹri | ≥760 | ≥420 | ≥27 |
Iṣeduro lọwọlọwọ:
| Opa opin (mm) | 2.5 | 3.2 | 4.0 |
| Alurinmorinlọwọlọwọ (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Akiyesi:
- Elekiturodu gbọdọ wa ni ndin fun wakati kan ni ayika 300 ℃ ṣaaju iṣẹ alurinmorin.Gbiyanju lati lo arc kukuru lati weld;
- O ṣe pataki lati nu ipata, epo, omi, ati awọn idoti lori awọn ẹya alurinmorin ṣaaju ṣiṣe alurinmorin.
3. Gbiyanju lati lo kekere agbara ila nigba alurinmorin, olona-Layer ati olona-kọja alurinmorin.
