Electrode ea Aluminium le Aluminium AlloyAWS E4043
Tlhaloso: AWS E4043 ke electrode ea alloy ea aluminium-silicon e nang le sekoahelo se thehiloeng letsoai. Sebelisa DCEP (electrode ea hona joale e tobileng). Ho tjheseletsa ha teko e potlakileng ea arc e khutšoanyane. Tšepe e kentsoeng e na le matla a itseng a mechini le khanyetso e ntle ea mapetso.
Tšebeliso: . E sebelisetsoa ho tjheseletsa poleiti ea aluminium, ho lahla aluminium-silicon, motsoako o akaretsang oa aluminium, aluminium e entsoeng ka letsoho le duralumin. Empa ha e ea lokela ho tjheseletsa metsoako ea aluminium-magnesium.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| Si | Fe | Cu | Mn | Ti | Zn | Al | Mg | Tse ling |
| 4.5 ~ 6.0 | ≤0.8 | ≤0.30 | ≤0.05 | ≤0.20 | ≤0.10 | Lula | ≤0.05 | ≤0.15 |
Khoeli e khothaletsoang:
| Bophara ba molamu (mm) | 3.2 | 4.0 | 5.0 |
| Ho tjheseletsa Hona Joale (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Tsebiso:
1. Electrode e bonolo haholo ho angoa ke mongobo, kahoo e lokela ho bolokoa ka setshelong se omileng se sa keneng moya ho thibela hore e se ke ea senyeha ka lebaka la mongobo; electrode e tlameha ho besoa mochesong o ka bang 150°C lihora tse 1 ho isa ho tse 2 pele e tjheseletsa;
2. Lipoleiti tsa ho kenya li lokela ho sebelisoa pele ho tjheseletsa, 'me tjheseletsa e lokela ho etsoa ka mor'a ho futhumatsa pele ho 200 ~ 300°C ho latela botenya ba tjheseletsa; molamu oa tjheseletsa o lokela ho ba o otlolohileng holim'a bokaholimo ba tjheseletsa, arc e lokela ho ba khutšoanyane kamoo ho ka khonehang, 'me ho nkeloa sebaka ha lithupa tsa tjheseletsa ho lokela ho etsoa kapele;
3. Ho tjheseletsa ho lokela ho hlwekiswa oli le ditshila pele ho tjheseletsa, mme slag e lokela ho tloswa ka hloko kamora ho tjheseletsa, mme e hlatswe ka mouoane kapa metsi a chesang.
