Tsanangudzo: T107 igorodhi yakachena yemhangura ine mhangura yakachena seyepakati uye yakafukidzwa ne-yakaderera-hydrogen sodium mhando flux.Shandisa DCEP (yakananga ikozvino electrode yakanaka).Yakanaka michina zvivakwa, yakanaka corrosion kuramba kumhepo uye mvura yegungwa, isingakodzere welding oksijeni-ine mhangura uye electrolytic mhangura.
Chishandiso: Inonyanya kushandiswa kugadzira zvinhu zvemhangura senge conductive copper mabara, mhangura yekupisa kupisa, uye mikoto yemvura yegungwa yezvikepe.Inogona zvakare kushandiswa kugadzira welding yekabhoni simbi zvikamu zvinopokana nekuora kwemvura yegungwa.
Kemikari yakagadzirwa nesimbi weld (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| ＞95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Elongation % |
| Guaranteed | ≥170 | ≥20 |
Yazvino inokurudzirwa:
| Tsvimbo dhayamita (mm) | 3.2 | 4.0 | 5.0 |
| WeldingCurrent (A) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Cherechedza:
1. I-electrode inofanira kubikwa inenge 200 ° C kweawa imwe isati yasvika, uye unyoro, mafuta, oxides uye zvimwe zvisina kuchena pamusoro pekuputika zvinofanira kubviswa.
2. Nekuda kwekupisa kwemhangura, uye tembiricha yekupisa yehuni ichaiswa weld inowanzokwira, kazhinji inodarika 500 °C.Kukura kweiyo welding ikozvino kunofanirwa kuenderana nekupisa kwekutanga kwesimbi yepasi;Edza vertical short arc welding.Inogona kushandiswa kudzoreredza mutsara kufamba kuvandudza weld kuumbwa.
3. Kune mawelds akareba, edza kushandisa back step welding nzira, uye kumhanya kwewelding kunofanirwa kunge kuri kukurumidza sezvinobvira.
Kana multi-layer welding, iyo slag pakati pezvikamu inofanira kubviswa zvachose;wapedza welding, rova weld nesando yemusoro kuti ubvise kushushikana,
Kuvandudza weld quality.
