Aluminium thiab Aluminium Alloy ElectrodeAWS E4043
Kev piav qhia: AWS E4043 yog ib qho txhuas-silicon alloy electrode nrog ib tug ntsev-raws li txheej. Siv DCEP (direct current electrode positive). Luv arc ceev kuaj vuam. Cov hlau deposited muaj ib tug tej yam mechanical zog thiab zoo tawg tsis kam.
Daim Ntawv Thov: Nws yog siv rau kev vuam ntawm cov phaj txhuas, txhuas-silicon casting, dav dav txhuas alloy, wrought txhuas thiab duralumin. Tab sis nws tsis haum rau kev vuam txhuas-magnesium alloys.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| Si | Fe | Cu | Mn | Ti | Zn | Al | Mg | Lwm yam |
| 4.5 ~ 6.0 | ≤0.8 | ≤0.30 | ≤0.05 | ≤0.20 | ≤0.10 | Nyob twj ywm | ≤0.05 | ≤0.15 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm lub pas nrig (hli) | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No (A) | 80 ~ 100 | 110 ~ 150 | 150 ~ 200 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yooj yim heev rau kev cuam tshuam los ntawm cov dej noo, yog li nws yuav tsum khaws cia rau hauv lub thawv qhuav kom tiv thaiv nws kom tsis txhob puas tsuaj vim cov dej noo; lub electrode yuav tsum tau ci ntawm li 150 ° C rau 1 txog 2 teev ua ntej vuam;
2. Yuav tsum siv cov phaj thaub qab ua ntej vuam, thiab vuam yuav tsum tau ua tom qab preheating rau 200 ~ 300 ° C raws li qhov tuab ntawm qhov vuam; tus pas nrig vuam yuav tsum perpendicular rau qhov chaw ntawm qhov vuam, lub arc yuav tsum luv li sai tau, thiab kev hloov cov pas nrig vuam yuav tsum tau ua sai sai;
3. Yuav tsum ntxuav cov roj thiab cov khoom tsis huv ua ntej vuam, thiab cov slag yuav tsum tau muab tshem tawm tom qab vuam, thiab yaug nrog cov pa lossis dej kub.
