I-Aluminiyam kunye ne-Aluminiyam ye-Aluminiyam i-ElectrodeAWS E4043
Inkcazo: I-AWS E4043 yi-aluminium-silicon alloy electrode ene-coating-based based coating.Sebenzisa i-DCEP (i-electrode yangoku echanekileyo).I-arc emfutshane yokuvavanya ngokukhawuleza ukuwelda.Intsimbi ediphozithiweyo inamandla athile omatshini kunye nokumelana nokuqhekeka okulungileyo.
Isicelo: .Isetyenziselwa ukuwelda ipleyiti ye-aluminium, i-aluminium-silicon casting, i-alloy ye-aluminium jikelele, i-aluminium edibeneyo kunye ne-duralumin.Kodwa ayifanelekanga ukuwelda i-aluminium-magnesium alloys.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| Si | Fe | Cu | Mn | Ti | Zn | Al | Mg | Okunye |
| 4.5 ~ 6.0 | ≤0.8 | ≤0.30 | ≤0.05 | ≤0.20 | ≤0.10 | Hlala | ≤0.05 | ≤0.15 |
yangoku eCetyisiweyo:
| Intonga yobubanzi (mm) | 3.2 | 4.0 | 5.0 |
| IWelding yangoku (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Isaziso:
1. I-electrode ilula kakhulu ukuchatshazelwa ngumswakama, ngoko kufuneka igcinwe kwisitya esomileyo esingenawo umoya ukuze sithintele ukuwohloka ngenxa yomswakama;i-electrode kufuneka ibhakwe malunga ne-150 ° C kwi-1 ukuya kwii-2 iiyure ngaphambi kwe-welding;
2. Iipleyiti ezixhasayo kufuneka zisetyenziswe phambi kwe-welding, kwaye i-welding kufuneka yenziwe emva kokufudumala kwi-200 ~ 300 ° C ngokobunzima be-weldment;intonga ye-welding kufuneka ibe yi-perpendicular kumphezulu we-weldment, i-arc kufuneka ibe mfutshane ngokunokwenzeka, kwaye ukutshintshwa kweentonga ze-welding kufuneka kuqhutywe ngokukhawuleza;
3. I-weldment kufuneka ihlanjululwe ngeoli kunye nokungcola phambi kwe-welding, kwaye i-slag kufuneka isuswe ngokucophelela emva kwe-welding, kwaye ihlanjwe nge-steam okanye ngamanzi ashushu.
