Aruminiyamu neAruminiyamu Chiwanikwa ElectrodeAWS E4043
Tsananguro: AWS E4043 ielectrode yealuminium-silicon alloy ine coating inobva mumunyu. Shandisa DCEP (direct current electrode positive). Short arc fast test welding. Simbi yakachengetwa ine simba remakanika uye inodzivirira kutsemuka zvakanaka.
Mashandisirwo: . Inoshandiswa pakusanganisa plate yearuminiyamu, kusanganisa aruminiyamu nesilicon, general alloy yearuminiyamu, aruminiyamu yakagadzirwa uye duralumin. Asi haina kukodzera pakusanganisa aruminiyamu nemagnesium.
Kuumbwa kwemakemikari esimbi ye 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 uripo | ≤0.05 | ≤0.15 |
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 3.2 | 4.0 | 5.0 |
| Kukweshera Kwemazuva (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Cherechedza:
1. Electrode iri nyore kukanganiswa nehunyoro, saka inofanira kuchengetwa mumudziyo wakaoma usingapindi mhepo kuti isaora nekuda kwehunyoro; electrode inofanira kubikwa pa150°C kweawa imwe kusvika maviri isati yaiswa welding;
2. Maplate ekumashure anofanira kushandiswa usati wabatanidza, uye kusanganisa kunofanira kuitwa mushure mekudziya kusvika 200 ~ 300°C zvichienderana neukobvu hwekubatanidza; tsvimbo yekusanganisa inofanira kunge yakatarisana nepamusoro pekubatanidza, arc inofanira kunge iri pfupi sezvinobvira, uye kutsiva tsvimbo dzekusanganisa kunofanira kuitwa nekukurumidza;
3. Kubatanidza kunofanira kucheneswa kubva mumafuta netsvina isati yabatanidzwa, uye tsvina inofanira kubviswa nokungwarira mushure mekusanganisa, uye kusukurudzwa neutsi kana mvura inopisa.
