I-Aluminium ne-Aluminium Alloy ElectrodeAWS E4043
Incazelo: I-AWS E4043 iyi-aluminium-silicon alloy electrode ene-coating esekelwe usawoti.Sebenzisa i-DCEP (i-electrode yamanje eqondile eqondile).I-arc ifushane yokuhlola i-welding esheshayo.Insimbi efakiwe inamandla athile okusebenza kanye nokumelana nokuqhekeka okuhle.
Isicelo: .Isetshenziselwa ukushisela ipuleti le-aluminium, i-aluminium-silicon casting, ingxubevange ye-aluminium ejwayelekile, i-aluminium eyenziwe yenziwe kanye ne-duralumin.Kodwa ayifanele ukushisela i-aluminium-magnesium alloys.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
| 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 |
Okwamanje okunconyiwe:
| Ububanzi benduku (mm) | 3.2 | 4.0 | 5.0 |
| I-Welding yamanje (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Isaziso:
1. I-electrode ilula kakhulu ukuthintwa umswakama, ngakho-ke kufanele igcinwe esitsheni esingenamoya esomile ukuze sivimbele ukuwohloka ngenxa yomswakama;i-electrode kufanele ibhakwe cishe ku-150 ° C amahora angu-1 kuya kwangu-2 ngaphambi kokushisela;
2. Amapuleti asekelayo kufanele asetshenziswe ngaphambi kokushisela, futhi ukushisela kufanele kwenziwe ngemva kokushisisa kusengaphambili ku-200 ~ 300°C ngokuvumelana nobukhulu bokushisela;induku ye-welding kufanele ibe yi-perpendicular ebusweni be-weldment, i-arc kufanele ibe mfushane ngangokunokwenzeka, futhi ukushintshwa kwezinduku zokushisela kufanele kwenziwe ngokushesha;
3. I-weldment kumele ihlanzwe ngamafutha kanye nokungcola ngaphambi kokuthungatha, futhi i-slag kufanele isuswe ngokucophelela ngemva kokuthungatha, futhi ihlanjululwe nge-steam noma ngamanzi ashisayo.
