Nickel uye Nickel Alloy Welding Electrode
Ni207
GB/T ENi4060
AWS A5.11 ENiCu-7
Tsananguro: Ni207 ielectrode yeMonel alloy ine hydrogen sodium coating shoma. Inoshandisa DCEP (direct current electrode positive) uye ine welding performance yakanaka uye inodzivirira kutsemuka.
Mashandisirwo: Pakusonwa kwesimbi dzeMonel kana dzakasiyana. Inogona zvakare kushandiswa pakusonwa kwesimbi dzepamusoro.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Fe | Si | Al | Ti | Cu | Nb | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≤2.5 | ≥62.0 | ≤0.015 | ≤0.020 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % |
| Yakavimbiswa | ≥480 | ≥200 | ≥27 |
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 3.2 | 4.0 |
| Welding current (A) | 90 ~ 110 | 110 ~ 150 |
Cherechedza:
1. Electrode inofanira kubikwa kwemaawa maviri pa300℃ isati yashandiswa pakunamira;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira. Edza kushandisa arc pfupi kunamira.
