KEV QHIA TXOG
Muaj ntau hom electrodes sib txawv siv rau hauv cov txheej txheem shielded metal arc welding, (SMAW). Lub hom phiaj ntawm phau ntawv qhia no yog los pab nrog kev txheeb xyuas thiab xaiv cov electrodes no.
KEV TXHEEB XYUAS ELECTRODE
Cov electrodes vuam arc raug txheeb xyuas siv AWS, (American Welding Society) tus lej system thiab ua los ntawm qhov loj me ntawm 1/16 txog 5/16. Ib qho piv txwv yuav yog ib tug pas nrig vuam uas txheeb xyuas tias yog 1/8" E6011 electrode.
Lub electrode yog 1/8 "hauv txoj kab uas hla.
Tus "E" sawv cev rau arc vuam electrode.
Tom ntej no yuav yog tus lej 4 lossis 5 tus lej uas tau muab luam tawm rau ntawm lub electrode. Ob tus lej thawj zaug ntawm tus lej 4 tus lej thiab 3 tus lej thawj zaug ntawm tus lej 5 tus lej qhia txog lub zog tensile tsawg kawg nkaus (hauv ntau txhiab phaus ib square inch) ntawm qhov vuam uas tus pas nrig yuav tsim tawm, kev ntxhov siab txo qis. Piv txwv li 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 txog tus lej kawg qhia txog qhov chaw uas lub electrode siv tau.
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 kev vuam tiaj tiaj
Ob tus lej kawg ua ke qhia txog hom txheej ntawm lub electrode thiab qhov hluav taws xob vuam uas lub electrode siv tau. Xws li DC ncaj, (DC -) DC rov qab (DC+) lossis AC
Kuv yuav tsis piav qhia txog hom txheej ntawm ntau yam electrodes, tab sis yuav muab piv txwv ntawm hom tam sim no uas txhua tus yuav ua haujlwm nrog.
Cov electrodes thiab cov hluav taws xob siv
● EXX10 DC+ (DC rov qab los yog DCRP) electrode zoo.
● EXX11 AC lossis DC- (DC ncaj lossis DCSP) electrode tsis zoo.
● EXX12 AC los yog DC-
● EXX13 AC, DC- los yog DC+
● EXX14 AC, DC- los yog DC+
● EXX15 DC+
● EXX16 AC los yog DC+
● EXX18 AC, DC- los yog DC+
● EXX20 AC, DC- lossis DC+
● EXX24 AC, DC- los yog DC+
● EXX27 AC, DC- los yog DC+
● EXX28 AC los yog DC+
COV HOM TAM SIM NO
SMAW ua tiav siv AC lossis DC tam sim no. Vim tias DC tam sim no ntws mus rau ib qho kev taw qhia, DC tam sim no tuaj yeem yog DC ncaj, (electrode negative) lossis DC thim rov qab (electrode positive). Yog tias DC thim rov qab, (DC+ LOS YOG DCRP) qhov vuam nkag mus tob. DC ncaj (DC- LOS YOG DCSP) qhov vuam yuav yaj sai dua thiab tso tawm sai dua. Qhov vuam yuav nkag mus nruab nrab.
AC tam sim no hloov nws lub polarity 120 zaug ib ob los ntawm nws tus kheej thiab tsis tuaj yeem hloov pauv zoo li DC tam sim no.
Qhov Loj ntawm lub electrode thiab cov amps siv
Cov hauv qab no yuav yog cov lus qhia yooj yim ntawm ntau yam amp uas siv tau rau cov electrodes sib txawv. Nco ntsoov tias cov kev ntsuas no tuaj yeem sib txawv ntawm ntau lub tuam txhab tsim hluav taws xob rau tib lub pas nrig loj. Tsis tas li ntawd, hom txheej ntawm electrode tuaj yeem cuam tshuam rau ntau yam amperage. Thaum ua tau, xyuas cov ntaub ntawv tsim khoom ntawm cov electrode uas koj yuav siv rau lawv cov chaw teeb tsa amperage pom zoo.
Rooj Electrode
| ELECTRODE DIAMETER (Tuab) | AMP RANGE | PHAJ |
| 1/16" | 20 - 40 | TXOG LI 3/16" |
| 3/32" | 40 - 125 | TXOG LI 1/4" |
| 1/8 | 75 - 185 | TSHAJ 1/8" |
| 5/32" | 105 - 250 | TSHAJ 1/4" |
| 3/16" | 140 - 305 | TSHAJ 3/8" |
| 1/4" | 210 - 430 | TSHAJ 3/8" |
| 5/16" | 275 - 450 | TSHAJ 1/2" |
Lus Cim! Cov khoom siv uas yuav tsum tau vuam tuab dua, qhov siab dua ntawm qhov tam sim no xav tau thiab qhov loj dua ntawm lub electrode xav tau.
QEE YAM ELECTRODE
Ntu no yuav piav qhia luv luv txog plaub lub electrodes uas feem ntau siv rau kev saib xyuas thiab kho cov hlau tsis muaj zog. Muaj ntau lwm cov electrodes muaj rau kev vuam lwm yam hlau. Nug koj tus neeg muag khoom vuam hauv zos kom paub txog lub electrode uas yuav tsum siv rau cov hlau uas koj xav vuam.
E6010Cov electrode no siv rau txhua qhov chaw vuam siv DCRP. Nws tsim cov vuam tob tob thiab ua haujlwm zoo rau cov hlau qias neeg, xeb, lossis pleev xim.
E6011Cov electrode no muaj cov yam ntxwv zoo ib yam li E6010, tab sis siv tau nrog AC thiab DC currents.
E6013Lub electrode no siv tau nrog AC thiab DC currents. Nws tsim tau ib qho weld uas nkag mus rau hauv nruab nrab nrog rau qhov zoo li lub hlaws weld zoo dua.
E7018Lub electrode no hu ua lub electrode hydrogen qis thiab siv tau nrog AC lossis DC. Lub txheej ntawm lub electrode muaj cov dej noo tsawg uas txo qhov kev nkag ntawm hydrogen rau hauv qhov vuam. Lub electrode tuaj yeem tsim cov vuam zoo x-ray nrog qhov nkag mus nruab nrab. (Nco ntsoov, lub electrode no yuav tsum khaws cia kom qhuav. Yog tias nws ntub, nws yuav tsum tau ziab hauv qhov cub pas nrig ua ntej siv.)
Vam tias cov ntaub ntawv yooj yim no yuav pab tus neeg vuam tshiab lossis tus kws vuam hauv tsev txheeb xyuas ntau hom electrodes thiab xaiv qhov yog rau lawv cov haujlwm vuam.
