Aluminium uye Aluminium Alloy ElectrodeAWS E4043
Tsanangudzo: AWS E4043 ialuminium-silicon alloy electrode ine munyu-based coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka).Pfupi arc inokurumidza kuyedza welding.Simbi yakaiswa ine imwe mechanical simba uye yakanaka crack resistance.
Application: .Inoshandiswa kugadzira simbi yealuminium plate, aluminium-silicon casting, general aluminium alloy, yakagadzirwa aluminium uye duralumin.Asi haikodzeri welding aluminium-magnesium alloys.
Kemikari yakagadzirwa nesimbi weld (%):
| Si | Fe | Cu | Mn | Ti | Zn | Al | Mg | Zvimwe |
| 4.5 ~ 6.0 | ≤0.8 | ≤0.30 | ≤0.05 | ≤0.20 | ≤0.10 | Ramba | ≤0.05 | ≤0.15 |
Yazvino inokurudzirwa:
| tsvimbo dhayamita (mm) | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Cherechedza:
1. Iyo electrode iri nyore kwazvo kukanganiswa nehunyoro, saka inofanira kuchengetwa mumudziyo wakaoma usina mhepo kuti urege kuparara nekuda kwekunyorova;iyo electrode inofanira kubikwa inenge 150 ° C kwemaawa 1 kusvika ku2 isati yasvika;
2. Mahwendefa ekutsigira anofanirwa kushandiswa asati apinza, uye welding inofanira kuitwa mushure mekupisa kusvika ku200 ~ 300 ° C maererano nehupamhi hwehuputi;iyo welding tsvimbo inofanira kunge iri perpendicular pamusoro peiyo weldment, iyo arc inofanira kunge yakapfupika sezvinobvira, uye kutsiva kwetsvimbo yekushongedza kunofanira kuitwa nekukurumidza;
3. Iyo weldment inofanira kucheneswa nemafuta uye tsvina isati yanyungudutswa, uye slag inofanira kunyatsobviswa mushure mekuputika, uye kushambidzwa nemhepo kana mvura inopisa.
