Electrode yeWelding yeCopper neCopper Alloy
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Tsananguro: T207 ielectrode yemhangura yemhangura ine silicon bronze core uye low hydrogen sodium coating. Shandisa DCEP (direct current electrode positive) ine hunhu hwakanaka hwemakanika. Inodzivirira ngura zvakanaka kune inorganic acids kunze kwe nitric acid, akawanda organic acids nemvura yegungwa.
Mashandisirwo: Yakakodzera kusanganisa mhangura, silicon bronze nendarira, kusanganisa pamusoro pemapeipi emakemikari, nezvimwewo.
Kuumbwa kwemakemikari esimbi ye weld (%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| ＞92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Hunhu hwesimbi ye weld:
| 试验项目 Chinhu chekuyedza | 抗拉强度 Simba rekusimba Mpa | 延伸率 Kureba % |
| 保证值 Yakavimbiswa | ≥270 | ≥20 |
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Cherechedza:
Zvekungwaririra:
1. Electrode inofanira kubikwa pa300°C kweawa imwe kusvika maviri isati yaiswa;
2. Hunyoro, mafuta, maokisijeni nezvimwe tsvina zviri pamusoro pe weldment zvinofanira kubviswa zvisati zvabatanidzwa.
3. Pakusanganisa silicon bronze kana welding pamusoro pesimbi, hapana kudziya kunodiwa. Tembiricha yekupisa yekusanganisa mhangura yakachena inenge 450°C, uye tembiricha yekupisa yekusanganisa mhangura inenge 300°C;
4. Kusonwa kwesimbi kupfupi kunofanira kushandiswa panguva yekusonwa. Panguva yekusonwa kwesimbi kunofanira kunge kwakabatana nesimbi dzakawanda.
zvabviswa zvachose; mushure mekusunga, gadzira weld nehammer yakatsetseka kuti unatsiridze tsanga, kubvisa kushushikana, uye kuvandudza kusimba uye plasticity yeweld.
