Nickel uye Nickel Alloy Welding Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Tsananguro: Ni202 ielectrode yeNi70Cu30 Monel alloy ine titanium calcium coating. Inogona kushandiswa kune ese ari maviri AC neDC. Simbi yakachengetwa ine simba rakanaka rekudzivirira kupwanyika nekuda kwehuwandu hwakakodzera hwemanganese neniobium. Inoshanda zvakanaka pakuwelda uye ine arc combustion yakasimba, haina kupararira zvakanyanya, inobvisa tsvina zviri nyore, uye ine weld yakanaka.
Mashandisirwo: Inoshandiswa pakunamira nickel-copper alloy nesimbi dzakasiyana, uye inogonawo kushandiswa sechinhu chinochinjika.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥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) | 2.5 | 3.2 | 4.0 |
| Welding current (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Cherechedza:
1. Electrode inofanira kubikwa kweawa imwe chete pakupisa kwe250℃ isati yashandiswa pakunamira;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira.
