Taw qhia
Muaj ntau ntau hom electrodes siv nyob rau hauv shielded hlau arc vuam, (SMAW) txheej txheem.Lub hom phiaj ntawm phau ntawv qhia no yog los pab nrog kev txheeb xyuas thiab xaiv cov electrodes.
ELECTRODE IDENTIFICATION
Arc welding electrodes raug txheeb xyuas siv AWS, (American Welding Society) tus lej system thiab ua rau qhov ntau thiab tsawg ntawm 1/16 txog 5/16.Ib qho piv txwv yuav yog lub vuam pas nrig pom tias yog 1/8 "E6011 electrode.
Lub electrode yog 1/8 "nyob rau hauv lub cheeb.
Lub "E" sawv cev rau arc vuam electrode.
Tom ntej no yuav yog tus lej 4 lossis 5 tus lej sau rau ntawm electrode.Thawj ob tus lej ntawm tus lej 4 tus lej thiab thawj 3 tus lej ntawm tus lej 5 tus lej qhia qhov tsawg kawg nkaus tensile lub zog (hauv ntau txhiab phaus ib square inch) ntawm qhov vuam uas tus pas nrig yuav tsim, kev ntxhov siab.Piv txwv yuav yog raws li nram no:
E60xx yuav muaj lub zog tensile ntawm 60,000 psi E110XX yuav yog 110,000 psi.
Tus lej tom ntej mus rau tus lej kawg qhia txog txoj haujlwm uas cov electrode tuaj yeem siv rau hauv.
1.EXX1X yog siv rau txhua txoj haujlwm
2.EXX2X yog siv rau hauv txoj haujlwm tiaj tus thiab kab rov tav
3.EXX3X yog rau cov vuam vuam
Ob tus lej kawg ua ke, qhia txog hom txheej txheej ntawm cov electrode thiab vuam tam sim no cov electrode tuaj yeem siv nrog.Xws li DC ncaj, (DC -) DC rov qab (DC +) lossis AC
Kuv yuav tsis piav txog hom txheej txheej ntawm ntau yam electrodes, tab sis yuav muab piv txwv ntawm hom tam sim no txhua tus yuav ua haujlwm nrog.
Cov hluav taws xob thiab cov khoom siv tam sim no siv
● EXX10 DC + (DC thim rov qab lossis DCRP) electrode zoo.
● EXX11 AC lossis DC- (DC ncaj lossis DCSP) electrode tsis zoo.
● EXX12 AC los yog DC-
● EXX13 AC, DC- lossis DC+
● EXX14 AC, DC- lossis DC+
● EXX15 DC+
● EXX16 AC lossis DC+
● EXX18 AC, DC- lossis DC+
● EXX20 AC, DC- lossis DC +
● EXX24 AC, DC- lossis DC +
● EXX27 AC, DC- lossis DC +
● EXX28 AC lossis DC+
Hom tam sim no
SMAW yog ua los ntawm AC lossis DCcurrent.Txij li thaum DC tam sim no ntws hauv ib qho kev taw qhia, DC tam sim no tuaj yeem yog DC ncaj, (electrode tsis zoo) lossis DC thim rov qab (electrode zoo).Nrog DC thim rov qab, (DC + OR DCRP) qhov vuam nkag yuav sib sib zog nqus.DC ncaj (DC- LOSSIS DCSP) qhov vuam yuav muaj qhov nrawm nrawm dua thiab tso nyiaj.Lub weld yuav muaj kev nkag mus rau nruab nrab.
AC tam sim no hloov nws lub polarity 120 zaug ib pliag los ntawm nws tus kheej thiab tsis tuaj yeem hloov tau li DC tam sim no.
ELECTRODE SIZE THIAB AMPS siv
Cov hauv qab no yuav ua raws li cov lus qhia yooj yim ntawm cov amp ntau yam uas tuaj yeem siv rau cov electrodes sib txawv.Nco ntsoov tias cov kev ntsuas no tuaj yeem sib txawv ntawm ntau yam khoom siv hluav taws xob rau tib lub pas nrig.Tsis tas li ntawd, hom txheej ntawm electrode tuaj yeem cuam tshuam qhov amperage ntau yam.Thaum ua tau, tshawb xyuas cov ntaub ntawv tsim khoom ntawm cov electrode koj yuav siv rau lawv qhov kev pom zoo amperage nqis.
Electrode Rooj
| ELECTRODE DIAMETER (THICNESS) | AMP RANGE | PLATE |
| 1/16 " | 20-40 | Mus txog 3/16 " |
| 3/32 " | 40-125 : kuv | Txog li 1/4 " |
| 1/8 | 75-185 : kuv | Tshaj 1/8 " |
| 5/32 " | 105-250 : kuv | NTAU 1/4 " |
| 3/16 " | 140-305 : kuv | 3/8 " |
| 1/4 " | 210-430 ib | 3/8 " |
| 5/16 " | 275-450 : kuv | NTAU 1/2 " |
Nco tseg!Qhov tuab ntawm cov khoom yuav tsum tau welded, qhov siab dua qhov xav tau tam sim no thiab qhov loj dua cov electrode xav tau.
IB QHOV CHAW UA HAUJ LWM
Tshooj lus no yuav piav qhia luv luv txog plaub lub electrodes uas feem ntau siv rau kev kho thiab kho vuam ntawm cov hlau me me.Muaj ntau ntau lwm yam electrodes muaj rau vuam ntawm lwm yam hlau.Tshawb xyuas nrog koj lub khw muag khoom vuam hauv zos rau cov khoom siv hluav taws xob uas yuav tsum tau siv rau cov hlau koj xav tau vuam.
E6010Cov electrode no yog siv rau txhua txoj haujlwm vuam siv DCRP.Nws ua rau qhov sib sib zog nqus nqus vuam thiab ua haujlwm zoo ntawm cov khoom qias neeg, xeb, lossis pleev xim rau hlau
E6011Cov electrode no muaj tib yam ntxwv ntawm E6010, tab sis tuaj yeem siv nrog AC thiab DC tam sim no.
E6013Cov electrode no tuaj yeem siv nrog AC thiab DC tam sim no.Nws tsim ib tug nruab nrab nkag mus rau weld nrog superior weld hlaws zoo li.
ua 7018Cov electrode no hu ua hydrogen electrode tsawg thiab tuaj yeem siv nrog AC lossis DC.Cov txheej txheej ntawm cov electrode muaj cov dej noo tsawg uas txo cov kev taw qhia ntawm hydrogen rau hauv qhov vuam.Cov electrode tuaj yeem tsim cov welds ntawm x-ray zoo nrog qhov nruab nrab nkag.(Nco ntsoov, cov electrode no yuav tsum tau muab cia kom qhuav. Yog tias nws ntub, nws yuav tsum tau qhuav hauv qhov cub ua ntej siv.)
Nws cia siab tias cov ntaub ntawv yooj yim no yuav pab cov neeg siv khoom tshiab lossis cov khw muag khoom hauv tsev txheeb xyuas ntau hom electrodes thiab xaiv qhov tseeb rau lawv cov haujlwm vuam.
