Mhangura neMhangura AlloyKushongedzaElectrode
T107
GB/T ECu
AWS A5.6 ECu
Tsananguro: T107 ielectrode yemhangura yakachena ine mhangura yakachena sepakati uye yakafukidzwa ne low-hydrogen sodium type flux. Shandisa DCEP (direct current electrode positive). Hunhu hwakanaka hwemakanika, kuramba ngura zvakanaka mumhepo nemvura yegungwa, hazvina kukodzera kusungirirwa kwemhangura ine oxygen uye mhangura ye electrolytic.
Mashandisirwo: Inonyanya kushandiswa pakusondera zvinhu zvemhangura zvakaita semabhawa emhangura anofambisa mhepo, zvinochinja-chinja kupisa kwemhangura, uye nzira dzemvura yegungwa dzezvikepe. Inogona zvakare kushandiswa pakusondera pamusoro pezvikamu zvesimbi yekabhoni zvinodzivirira ngura yemvura yegungwa.
Kuumbwa kwemakemikari esimbi ye weld (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| ＞95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Kureba % |
| Yakavimbiswa | ≥170 | ≥20 |
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 3.2 | 4.0 | 5.0 |
| KushongedzaZvazvino (A) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Cherechedza:
1. Electrode inofanira kubikwa pa200°C kweawa imwe chete isati yabatanidzwa, uye hunyoro, mafuta, maoxide nezvimwe tsvina zviri pamusoro pesimbi zvinofanirwa kubviswa.
2. Nekuda kwekufambiswa kwemafuta emhangura, uye tembiricha yekupisa yehuni dzinofanira kusungirirwa inowanzo kuve yakakwira, kazhinji pamusoro pe500 °C. Hukuru hwemagetsi ekushongedza hunofanira kuenderana netembiricha yekupisa yesimbi yekutanga; Edza kushongedza vertical short arc. Inogona kushandiswa kudzokorora kufamba kwemutsara kuti uvandudze kuumbwa kwesimbi.
3. Kune welds refu, edza kushandisa nzira yekuweldra yekumashure, uye kumhanya kwekuweldra kunofanira kunge kuri nekukurumidza sezvinobvira.
Kana muchibatanidza zvinhu zvakawanda, tsvina iri pakati pezvikamu inofanira kubviswa zvachose; mushure mekusanganisa, gadzirai weld nehammer yakatsetseka kuti muderedze kushushikana,
Kuvandudza mhando yekuwedera.
