General Yam Txog Vuam Electrodes
Tianqiao vuam electrode yog qhov kev xaiv
Vuam electrodes yog ib qho tseem ceeb, thiab nws yog ib qho tseem ceeb uas tus welder thiab cov neeg ua haujlwm paub txog yam twg los siv rau ntau txoj haujlwm.
Dab tsi yog vuam electrodes?
Ib qho electrode yog coated hlau hlau, uas yog ua los ntawm cov ntaub ntawv zoo ib yam li cov hlau welded.Rau qhov pib, muaj cov khoom siv hluav taws xob thiab tsis siv hluav taws xob.Hauv cov ntaub thaiv npog hlau arc vuam (SMAW) tseem hu ua stick, electrodes yog consumable, uas txhais tau hais tias cov electrode tau noj thaum nws siv thiab melts nrog vuam.Hauv Tungsten Inert Gas welding (TIG) electrodes tsis yog siv tau, yog li lawv tsis yaj thiab ua ib feem ntawm cov vuam.Nrog Gas Hlau Arc Vuam (GMAW) los yog MIG welding, electrodes tsis tu ncua pub hlau.2 Flux-cored arc vuam yuav tsum tau noj tsis tu ncua ntawm cov khoom siv tubular electrode uas muaj cov flux.
Yuav ua li cas xaiv vuam electrodes?
Xaiv ib qho electrode yog txiav txim siab los ntawm cov kev cai ntawm txoj haujlwm vuam.Cov no suav nrog:
- Tensile zog
- Ductility
- Corrosion kuj
- Base hlau
- Weld txoj hauj lwm
- Polarity
- Tam sim no
Muaj lub teeb thiab hnyav coated electrodes.Lub teeb coated electrodes muaj lub teeb txheej uas siv los ntawm txhuam, txau, dipping, ntxuav, so, lossis tumbling.Heavy coated electrodes yog coated los ntawm extrusion los yog dripping.Muaj peb yam tseem ceeb ntawm cov txheej hnyav: ntxhia, cellulose, lossis ob qho sib xyaw ua ke.Cov coatings hnyav yog siv rau vuam cam khwb cia hlau, steels, thiab tawv tawv.
Cov lej thiab cov tsiaj ntawv txhais li cas ntawm cov welding rods?
Lub koom haum American Welding Society (AWS) muaj cov lej xov tooj uas muab cov ntaub ntawv hais txog cov khoom siv hluav taws xob tshwj xeeb, xws li daim ntawv thov twg nws yog qhov zoo tshaj plaws siv rau thiab yuav ua li cas nws yuav tsum tau ua kom ua tau zoo tshaj plaws.
| Tus lej | Hom Txheej Txheej | Vuam tam sim no |
| 0 | Siab cellulose sodium | DC + |
| 1 | High cellulose poov tshuaj | AC, DC + lossis DC- |
| 2 | High titania sodium | AC, DC- |
| 3 | High titania potassium | AC, DC + |
| 4 | Hlau hmoov, titania | AC, DC + lossis DC- |
| 5 | Tsawg hydrogen sodium | DC + |
| 6 | Tsawg hydrogen potassium | AC, DC + |
| 7 | High hlau oxide, poov tshuaj hmoov | AC, DC + lossis DC- |
| 8 | Tsawg hydrogen potassium, hlau hmoov | AC, DC + lossis DC- |
Tus "E" qhia txog arc vuam electrode.Thawj ob tus lej ntawm tus lej 4 thiab thawj peb tus lej ntawm 5 tus lej sawv cev rau lub zog tensile.Piv txwv li, E6010 txhais tau tias 60,000 phaus ib square inch (PSI) tensile zog thiab E10018 txhais tau tias 100,000 psi tensile zog.Tus lej tom ntej mus rau tus lej kawg qhia txog txoj haujlwm.Yog li, "1" sawv cev rau txhua txoj haujlwm electrode, "2" rau lub tiaj tus thiab kab rov tav electrode, thiab "4" rau lub tiaj, kab rov tav, ntsug thiab sab saum toj electrode.Ob tus lej kawg qhia txog hom txheej txheej thiab vuam tam sim no.4
| E | 60 | 1 | 10 |
| Hluav taws xob | Tensile zog | Txoj hauj lwm | Hom Txheej & Tam sim no |
Paub txog cov khoom sib txawv ntawm cov electrodes thiab lawv daim ntawv thov yuav pab tau kom ua tiav txoj haujlwm vuam kom raug.Kev txiav txim siab suav nrog txoj kev vuam, cov khoom siv welded, sab hauv tsev / sab nraum zoov, thiab vuam txoj haujlwm.Xyaum nrog ntau yam vuam phom thiab electrodes tuaj yeem pab koj txiav txim siab seb lub tshuab electrode siv rau qhov haujlwm vuam dab tsi.
