Nickel uye Nickel Alloy Welding Electrode
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Tsananguro: Ni327-4 ielectrode yakagadzirwa nenickel ine hydrogen sodium coating shoma. Shandisa DCEP (electrode yakananga yemagetsi)yakanaka). Inoshanda zvakanaka pakuwedera ine arc combustion yakagadzikana, haina kupfapfaidza, iri nyore kubvisa tsvina,
uye weld yakanaka. Hunhu hwemuchina hwesimbi yakachengetwa hwakagadzikana.
Mashandisirwo: Inoshandiswa pakusanganisa ma alloys e nickel-chromium-molybdenum ane kabhoni shoma, akadai seHastelloy C276, ASTM B574, B575, B619, B622, B626, uye inogona kushandiswawo pakusanganisa simbi dzakasiyana nedzimwe alloys dzakavakirwa pa nickel.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.02 | ≤1.0 | ≤0.2 | 14.5 ~ 16.5 | ≥50.0 | 15.0 ~ 17.0 |
| W | Co | Fe | S | P | Zvimwe |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % |
| Yakavimbiswa | ≥690 | ≥400 | ≥22 |
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 2.5 | 3.2 | 4.0 |
| Welding current (A) | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Cherechedza:
1. Electrode inofanira kubikwa kweawa imwe chete pa300℃ isati yashandiswa pakusanganisa. Edza kushandisa arc pfupi kusanganisa;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira.
3. Edza kushandisa simba diki pakusanganisa, kusanganisa tambo dzakawanda uye kusanganisa tambo dzakawanda.
