I-Aluminium kunye ne-Aluminium Alloy ElectrodeI-AWS E4043
Inkcazo: I-AWS E4043 yi-electrode ye-aluminium-silicon alloy ene-coating esekelwe kwityuwa. Sebenzisa i-DCEP (i-electrode yangoku ngqo). I-short arc fast test welding. Isinyithi esifakwe kwi-deposit sinamandla athile oomatshini kunye nokumelana okuhle nokuqhekeka.
Ukusetyenziswa: . Isetyenziselwa ukuwelda ipleyiti ye-aluminiyam, ukuthungwa kwe-aluminiyam-silicon, i-aluminiyam jikelele, i-aluminiyam eqinisiweyo kunye ne-duralumin. Kodwa ayifanelekanga ukuwelda i-aluminiyam-magnesium alloys.
Ukwakheka kweekhemikhali zesinyithi esijiyiweyo (%):
| 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 ecetyiswayo:
| Ububanzi bentonga （mm） | 3.2 | 4.0 | 5.0 |
| Ukuwelda Ngoku (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Isaziso:
1. I-electrode kulula kakhulu ukuyichaphazela kukufuma, ngoko ke kufuneka igcinwe kwisikhongozeli esomileyo esingangeni moya ukuze ingaboli ngenxa yokufuma; i-electrode kufuneka ibhakwe malunga ne-150°C kangangeyure e-1 ukuya kwezi-2 ngaphambi kokuba idityaniswe;
2. Iipleyiti zokuxhasa kufuneka zisetyenziswe ngaphambi kokuwelda, kwaye ukuwelda kufuneka kwenziwe emva kokufudumeza kwangaphambili ukuya kuma-200 ~ 300°C ngokobukhulu bokuwelda; intonga yokuwelda kufuneka ijonge ngqo kumphezulu wokuwelda, i-arc kufuneka ibe mfutshane kangangoko, kwaye ukutshintshwa kweentonga zokuwelda kufuneka kwenziwe ngokukhawuleza;
3. I-weldment kufuneka icocwe ioyile kunye nokungcola ngaphambi kokuba i-weld, kwaye i-slag kufuneka isuswe ngononophelo emva koku-weld, kwaye ihlanjwe ngomphunga okanye ngamanzi ashushu.
