Aluminium thiab Aluminium Alloy ElectrodeAWS E4043
Nqe lus piav qhia: AWS E4043 yog ib qho txhuas-silicon alloy electrode nrog cov ntsev-raws li txheej.Siv DCEP (direct tam sim no electrode zoo).Short arc ceev kuaj vuam.Cov hlau deposited muaj tej yam txhua yam muaj zog thiab zoo tawg kuj.
Daim ntawv thov: .Nws yog siv rau vuam ntawm txhuas phaj, txhuas-silicon casting, dav txhuas alloy, wrought txhuas thiab duralumin.Tab sis nws tsis haum rau vuam aluminium-magnesium alloys.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| 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 (mm) | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no (A) | 80 ~ 100 | 110 ~ 150 ib | 150 ~ 200 hli |
Daim ntawv ceeb toom:
1. Cov electrode yog ib qho yooj yim heev rau kev cuam tshuam los ntawm noo noo, yog li nws yuav tsum tau muab cia rau hauv ib lub thawv qhuav airtight kom tsis txhob deteriorating vim ya raws;cov electrode yuav tsum tau ci ntawm li 150 ° C rau 1 mus rau 2 teev ua ntej vuam;
2. Rov qab daim hlau yuav tsum tau siv ua ntej vuam, thiab vuam yuav tsum tau ua tom qab preheating rau 200 ~ 300 ° C raws li lub thickness ntawm cov vuam;lub vuam pas nrig yuav tsum yog perpendicular mus rau qhov chaw ntawm lub vuam, lub arc yuav tsum luv li sai tau, thiab hloov vuam rods yuav tsum tau ua sai sai;
3. Lub vuam yuav tsum tau ntxuav ntawm cov roj thiab cov impurities ua ntej vuam, thiab cov slag yuav tsum tau ua tib zoo tshem tawm tom qab vuam, thiab yaug nrog chav lossis dej kub.
