Mkuwa ndi Aloyi wa MkuwakuwotchereraElekitirodi
T107
GB/T ECu
AWS A5.6 ECu
Kufotokozera: T107 ndi electrode ya mkuwa yeniyeni yokhala ndi mkuwa weniweni ngati pakati ndipo yokutidwa ndi flux ya sodium yochepa. Gwiritsani ntchito DCEP (electrode ya direct current positive). Makhalidwe abwino a makina, kukana dzimbiri bwino ku mlengalenga ndi madzi a m'nyanja, sikoyenera kuwotcherera mkuwa wokhala ndi mpweya ndi mkuwa wa electrolytic.
Kugwiritsa Ntchito: Amagwiritsidwa ntchito makamaka polumikiza zinthu zamkuwa monga mipiringidzo yamkuwa yoyendetsa, zosinthira kutentha kwa mkuwa, ndi njira zoyendetsera madzi a m'nyanja za sitima. Angagwiritsidwenso ntchito polumikiza zinthu zachitsulo cha kaboni pamwamba pa nthaka zomwe sizingawonongeke ndi dzimbiri la madzi a m'nyanja.
Kapangidwe ka mankhwala a chitsulo chosungunula (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| ＞95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Kapangidwe ka makina a chitsulo chosungunula:
| Chinthu choyesera | Kulimba kwamakokedwe Mpa | Kutalikitsa % |
| Chotsimikizika | ≥170 | ≥20 |
Mphamvu yovomerezeka:
| M'mimba mwake wa ndodo (mm) | 3.2 | 4.0 | 5.0 |

Zindikirani:
1. Electrode iyenera kuphikidwa pa kutentha kwa pafupifupi 200°C kwa ola limodzi musanayike, ndipo chinyezi, mafuta, ma oxide ndi zonyansa zina pamwamba pa weldment ziyenera kuchotsedwa.
2. Chifukwa cha kutentha kwa mkuwa, komanso kutentha kwa matabwa omwe akuwotcherera nthawi zambiri kumakhala kokwera, nthawi zambiri kupitirira 500 °C. Kukula kwa mphamvu yowotcherera kuyenera kugwirizana ndi kutentha kwa chitsulo choyambira; Yesani kuwotcherera kwa arc yochepa. Ingagwiritsidwe ntchito poyendetsa motsatizana kuti muwongolere mapangidwe a weld.
3. Pa ma welds ataliatali, yesani kugwiritsa ntchito njira yoweldra kumbuyo, ndipo liwiro la weld liyenera kukhala lachangu momwe mungathere.
Mukalumikiza zinthu zambiri, matope pakati pa zigawo ayenera kuchotsedwa kwathunthu; mukamaliza kulumikiza, gwirani cholumikiziracho ndi nyundo yathyathyathya kuti muchepetse kupsinjika,
Sinthani mtundu wa weld.
