Kufotokozera: T107 ndi elekitirodi yoyera yamkuwa yokhala ndi mkuwa wangwiro ngati pachimake komanso yokutidwa ndi mtundu wochepera wa haidrojeni wa sodium.Gwiritsani ntchito DCEP (mwachindunji panopa electrode positive).Zabwino zamakina, kukana kwa dzimbiri kwa mpweya ndi madzi a m'nyanja, osati koyenera kuwotcherera mpweya wokhala ndi mkuwa ndi mkuwa wa electrolytic.
Ntchito: Imagwiritsidwa ntchito kwambiri pakuwotcherera zida zamkuwa monga mipiringidzo yamkuwa ya conductive, zotenthetsera zamkuwa, ndi machubu amadzi am'nyanja a zombo.Itha kugwiritsidwanso ntchito powotcherera mbali za zitsulo za kaboni zomwe zimalimbana ndi dzimbiri lamadzi am'nyanja.
Chemical zikuchokera weld zitsulo (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| ＞95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Zimango za weld zitsulo:
| Yesani chinthu | Kulimba kwamakokedwe Mpa | Elongation % |
| Zotsimikizika | ≥170 | ≥20 |
Zomwe tikulimbikitsidwa:
| Ndodo diameter (mm) | 3.2 | 4.0 | 5.0 |
| KuwotchereraPanopa (A) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Zindikirani:
1. Elekitirodi iyenera kuphikidwa pafupifupi 200 ° C kwa ola limodzi musanayambe kuwotcherera, ndipo chinyezi, mafuta, oxides ndi zonyansa zina pamwamba pa weldment ziyenera kuchotsedwa.
2. Chifukwa cha matenthedwe amkuwa, komanso kutentha kwa nkhuni zowotcherera nthawi zambiri kumakhala kokwera kwambiri, nthawi zambiri kuposa 500 °C.Ukulu wa kuwotcherera panopa ayenera n'zogwirizana ndi preheating kutentha m'munsi zitsulo;Yesani kuwotcherera kwa arc yayifupi.Itha kugwiritsidwa ntchito pobwereza kusuntha kwa mzere kuti kuwongolera mapangidwe a weld.
3. Kwa ma welds ataliatali, yesani kugwiritsa ntchito njira yowotcherera yobwerera kumbuyo, ndipo liwiro la kuwotcherera liyenera kukhala mwachangu momwe mungathere.
Pamene kuwotcherera kwamitundu yambiri, slag pakati pa zigawo iyenera kuchotsedwa kwathunthu;mutatha kuwotcherera, nyundo nyundo ndi nyundo yamutu kuti muchepetse kupsinjika;
Sinthani khalidwe la weld.
