Mhangura uye Copper Alloy Welding Electrode
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Tsanangudzo: T207 icopper alloy electrode ine silicon bronze core uye yakaderera hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka) ine mikuru michanicha zvinhu.Iyo ine yakanaka corrosion resistance kune inorganic acids kunze kwenitric acid, yakawanda organic acids uye mvura yegungwa.
Kushandisa: Yakakodzera simbi yemhangura, silicon bhuronzi nemhangura, yakatarisana nekunama kwemaraini emakemikari emuchina mapaipi, nezvimwe.
Kemikari yakagadzirwa nesimbi weld (%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| ＞92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Mechanical zvimiro zve weld simbi:
| 试验项目 Test chinhu | 抗拉强度 Kusimba simba Mpa | 延伸率 Elongation % |
| 保证值 Guaranteed | ≥270 | ≥20 |
Yazvino inokurudzirwa:
| Tsvimbo dhayamita (mm) | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Cherechedza:
Zvekungwaririra:
1. Iyo electrode inofanira kubikwa inenge 300 ° C kwemaawa 1 kusvika ku2 isati yasvika;
2. Kunyorova, mafuta, okisidhi uye zvimwe zvisina kuchena pamusoro peiyo weldment inofanira kubviswa isati yatungidzirwa.
3. Kana welding silicon bhuronzi kana surfacing welding pasimbi, hapana preheating zvinodiwa.Preheating tembiricha yewelding mhangura yakachena ingangoita 450°C, uye tembiricha yepreheating yebras yekukuchidzira inenge 300°C;
4. Short-arc welding inofanira kushandiswa panguva yekuputika.Munguva ye-multi-layer welding, slag pakati pezvikamu inofanira kuva
kubviswa zvachose;mushure mekugadzira, gadzira weld nesando yemusoro kuti unatse zviyo, kubvisa kushushikana, uye kuvandudza simba uye plasticity ye weld.
