I-Aluminium ne-Aluminium Alloy ElectrodeI-AWS E4043
Incazelo: I-AWS E4043 iyi-electrode ye-aluminium-silicon alloy ene-coating esekelwe kusawoti. Sebenzisa i-DCEP (i-electrode yamanje eqondile). Ukushisela okusheshayo kwe-arc okusheshayo. Insimbi efakiwe inamandla athile okusebenza kanye nokumelana okuhle kokuqhekeka.
Ukusetshenziswa: . Isetshenziselwa ukushisela ipuleti le-aluminium, ukuthungwa kwe-aluminium-silicon, i-aluminium alloy ejwayelekile, i-aluminium eqinisiwe kanye ne-duralumin. Kodwa ayifaneleki ukushisela i-aluminium-magnesium alloys.
Ukwakheka kwamakhemikhali kwensimbi eshidiwe (%):
| 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 |
I-current enconyiwe:
| Ububanzi benduku (mm) | 3.2 | 4.0 | 5.0 |
| Ukushisela Kwamanje (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Isaziso:
1. I-electrode kulula kakhulu ukuthintwa umswakama, ngakho-ke kufanele igcinwe esitsheni esomile esingangeni moya ukuze igweme ukuwohloka ngenxa yomswakama; i-electrode kumele ibhakwe cishe ku-150°C ihora eli-1 kuya kwamabili ngaphambi kokushisela;
2. Amapuleti okusekela kufanele asetshenziswe ngaphambi kokushisela, futhi ukushisela kufanele kwenziwe ngemva kokushisisa kusengaphambili kufike ku-200 ~ 300°C ngokuya ngobukhulu bokushisela; induku yokushisela kufanele iqonde ngqo ebusweni bokushisela, i-arc kufanele ibe mfushane ngangokunokwenzeka, futhi ukushintshwa kwezinduku zokushisela kumele kwenziwe ngokushesha;
3. Ukushisela kumele kuhlanzwe uwoyela nokungcola ngaphambi kokushisela, futhi i-slag kufanele isuswe ngokucophelela ngemva kokushisela, bese ihlanzwa ngomusi noma ngamanzi ashisayo.
