Aluminiyamu ndi Aluminiyamu Alloy ElectrodeAWS E4043
Kufotokozera: AWS E4043 ndi electrode ya aluminiyamu-silicon alloy yokhala ndi chophimba chochokera ku mchere. Gwiritsani ntchito DCEP (electrode yamagetsi yolunjika). Kuwotcherera kwafupipafupi kwa arc fast test. Chitsulo choyikidwacho chili ndi mphamvu inayake yamakina komanso kukana ming'alu yabwino.
Kugwiritsa Ntchito: . Imagwiritsidwa ntchito powotcherera mbale za aluminiyamu, kuponyera aluminiyamu-silicon, aloyi ya aluminiyamu wamba, aluminiyamu yophwanyidwa ndi duralumin. Koma siyoyenera kuwotcherera aloyi a aluminiyamu-magnesium.
Kapangidwe ka mankhwala a chitsulo chosungunula (%):
| Si | Fe | Cu | Mn | Ti | Zn | Al | Mg | Zina |
| 4.5 ~ 6.0 | ≤0.8 | ≤0.30 | ≤0.05 | ≤0.20 | ≤0.10 | Khalanibe | ≤0.05 | ≤0.15 |
Mphamvu yovomerezeka:
| M'mimba mwake wa ndodo (mm) | 3.2 | 4.0 | 5.0 |
| Kuwotcherera Kwamakono (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Zindikirani:
1. Electrode ndi yosavuta kukhudzidwa ndi chinyezi, choncho iyenera kusungidwa mu chidebe chouma chosalowa mpweya kuti isawonongeke chifukwa cha chinyezi; electrode iyenera kuphikidwa pa kutentha kwa pafupifupi 150°C kwa ola limodzi mpaka awiri isanawotchedzeredwe;
2. Mapepala olumikizira kumbuyo ayenera kugwiritsidwa ntchito musanawotchere, ndipo kuwotcherera kuyenera kuchitika mutawotcherera pasadakhale mpaka 200 ~ 300°C malinga ndi makulidwe a chowotcherera; ndodo yowotcherera iyenera kukhala yolunjika pamwamba pa chowotcherera, arc iyenera kukhala yayifupi momwe ingathere, ndipo kusintha ndodo zowotcherera kuyenera kuchitika mwachangu;
3. Cholumikiziracho chiyenera kutsukidwa mafuta ndi zinthu zina zosafunika musanachigwiritse ntchito, ndipo matope ayenera kuchotsedwa mosamala mutachigwiritsa ntchito, ndikutsukidwa ndi nthunzi kapena madzi otentha.
