Copper ndi Copper Alloy Welding Electrode
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Description: T207 ndi electrode copper alloy electrode yokhala ndi silicon bronze pachimake komanso zokutira za hydrogen sodium.Gwiritsani ntchito DCEP (elekitirodi yeniyeni yeniyeni) yokhala ndi makina akuluakulu.Ili ndi kukana kwa dzimbiri kwa ma inorganic acid kupatula nitric acid, ma organic acid ambiri ndi madzi a m'nyanja.
Ntchito: Ndi oyenera kuwotcherera zamkuwa, pakachitsulo mkuwa ndi mkuwa, kuwotcherera pamwamba pa linings wa mapaipi makina makina, etc.
Chemical zikuchokera weld zitsulo (%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| ＞92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Zimango za weld zitsulo:
| 试验项目 Yesani chinthu | 抗拉强度 Kulimba kwamakokedwe Mpa | 延伸率 Elongation % |
| 保证值 Zotsimikizika | ≥270 | ≥20 |
Zomwe tikulimbikitsidwa:
| Ndodo diameter (mm) | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 90-130 | 110 ~ 160 | 150 ~ 200 |
Zindikirani:
Kusamalitsa:
1. Elekitirodi iyenera kuphikidwa pafupifupi 300 ° C kwa maola 1 mpaka 2 musanayambe kuwotcherera;
2. Chinyezi, mafuta, oxides ndi zonyansa zina pamwamba pa weldment ayenera kuchotsedwa pamaso kuwotcherera.
3. Mukawotcherera silicon mkuwa kapena kuwotcherera pazitsulo, palibe kutentha koyenera.Kutentha koyambirira kwa kuwotcherera mkuwa koyera ndi pafupifupi 450 ° C, ndipo kutentha kwa preheating kwa mkuwa wowotcherera ndi pafupifupi 300 ° C;
4. Kuwotcherera kwafupipafupi kuyenera kugwiritsidwa ntchito powotcherera.Pa kuwotcherera kwamitundu yambiri, slag pakati pa zigawo ziyenera kukhala
kuchotsedwa kwathunthu;pambuyo kuwotcherera, nyundo weld ndi nyundo lathyathyathya mutu kuyeretsa mbewu, kuthetsa nkhawa, ndi kupititsa patsogolo mphamvu ndi pulasitiki wa weld.
