Aluminium le Aluminium Alloy ElectrodeAWS E4043
Tlhaloso: AWS E4043 ke aluminium-silicon alloy electrode e nang le seaparo se entsoeng ka letsoai.Sebelisa DCEP (electrode e nepahetseng hona joale).Li-welding tse khutšoane tsa tlhahlobo ea arc.Tšepe e kentsoeng e na le matla a itseng a mochini le khanyetso e ntle ea crack.
Kopo:.E sebelisetsoa ho cheselletsa poleiti ea aluminium, aluminium-silicon casting, alloy ea kakaretso ea aluminium, aluminium e entsoeng le duralumin.Empa ha e loketse ho cheselletsa li-alloys tsa aluminium-magnesium.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
| Si | Fe | Cu | Mn | Ti | Zn | Al | Mg | Tse ding |
| 4.5 ~ 6.0 | ≤0.8 | ≤0.30 | ≤0.05 | ≤0.20 | ≤0.10 | Lula | ≤0.05 | ≤0.15 |
Nako e khothalelitsoeng:
| Bophara ba molamu (mm) | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Tlhokomeliso:
1. Electrode e bonolo haholo ho angoa ke mongobo, kahoo e lokela ho bolokoa ka setsing se omeletseng se se nang moea ho thibela ho senyeha ka lebaka la mongobo;eleketrode e lokela ho apehoa ka hoo e ka bang 150 ° C bakeng sa 1 ho lihora tse 2 pele tjheseletsa;
2. Lipoleiti tse tšehetsang li lokela ho sebelisoa pele ho tjheseletsa, 'me welding e lokela ho etsoa ka mor'a ho futhumatsa pele ho 200 ~ 300 ° C ho ea ka botenya ba ho cheselletsa;molamu oa welding e lokela ho ba perpendicular holim'a weldment, arc e lokela ho ba khutšoanyane ka hohle kamoo ho ka khonehang, 'me ho nkeloa sebaka ha lithupa tsa welding ho tlameha ho etsoa kapele;
3. The weldment e tlameha ho hloekisoa ka oli le litšila pele ho tjheseletsa, 'me slag e lokela ho tlosoa ka hloko ka mor'a hore e chese, ebe e hlatsuoa ka mouoane kapa metsi a chesang.
