Nickel uye Nickel Alloy Welding Electrode
Ni307-1
GB/T ENi6062
AWS A5.11 ENiCrFe-1
Tsananguro: Ni307-1 ielectrode yakagadzirwa nenickel ine hydrogen sodium shoma. Shandisa DCEP (direct current electrode positive). Sezvo weld ine Nb, simbi yakachengetwa ine plasticity yakanaka uye inodzivirira kutsemuka.
Mashandisirwo: Inoshandiswa pakusanganisa nickel-chromium-iron alloys (senge UNS N06600, UNS N06601) uye pamusoro pesimbi. Ine hunhu hwakanaka hwekusanganisa simbi. Inogona zvakare kushandiswa patembiricha yekushanda ye980°C, asi kana tembiricha yakakwira kupfuura 820°C, kuramba kweoxidation nesimba zvinodzikira.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Fe | Si | Cu | Ni | Cr | Nb + Ta | S | P | Zvimwe |
| ≤0.08 | ≤3.5 | ≤11.0 | ≤0.8 | ≤0.5 | ≥62.0 | 13.0 ~ 17.0 | 0.5 ~ 4.0 | ≤0.015 | ≤0.020 | ≤0.50 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % |
| Yakavimbiswa | ≥550 | ≥360 | ≥27 |
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding current (A) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 | 130 ~ 180 |
Cherechedza:
1. Electrode inofanira kubikwa kweawa imwe chete pakupisa kwe300℃ isati yashandiswa pakunamira;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira. Edza kushandisa arc pfupi kunamira.
