AWS A5.23: ECF3 Cov Hlau Uas Muaj Cov Hlau Uas Muaj Cov Hlau Qis
PIAV TXOG:
AWS A5.23: ECF3 yog ib qho hlau sib xyaw ua ke uas muaj cov hlau sib xyaw ua ke tsawg tsawg rau kev vuam hauv qab dej hauv cov ntawv thov muaj zog heev. Thiab nws ua tau raws li AWS A5.23 chemistry F3, thiab yog tsim los rau cov qib tensile siab tshaj 100 ksi.
NTA & COV TXHOJ ZOO:
Cov hlau-cored hlau tuaj yeem muab cov nqi tso tawm zoo dua piv rau cov hlau khov kho ntawm cov amperages sib piv
Cov xov hlau cored muab cov ntaub ntawv nkag mus dav dua piv rau cov xov hlau khov kho ntawm cov kev sib piv vuam
Cov kev xav tau ntawm cov tshuaj lom neeg ntawm cov khoom siv vuam yog zoo ib yam li cov ntawm EF3 cov xov hlau khov kho
Cov tshuaj lom neeg ntawm cov khoom siv vuam muaj tsawg dua 1% nickel
Zoo heev rau qhov kub thiab txias uas tsis kub dhau hauv ob qho tib si raws li-welded thiab kev ntxhov siab-relieved tej yam kev mob
Muab peev xwm los ua kom ceev nrooj mus ncig kom muaj txiaj ntsig zoo dua
Pab tiv thaiv kom tsis txhob kub hnyiab thaum vuam ntawm cov hluav taws xob siab ntawm cov hauv paus hniav thiab cov ntaub ntawv nyias nyias.
Haum rau lwm txoj hauv kev ua haujlwm siab dua hauv ntau daim ntawv thov uas tam sim no siv EF3 solid wire
Haum rau kev siv rau hauv cov ntawv thov roj qaub uas qhov kev ntxhov siab corrosion tawg vim hydrogen-sulfide yog qhov txhawj xeeb
Pab txo qhov kev pheej hmoo ntawm kev tawg hauv cov ntawv thov tseem ceeb thiab cov chaw ua haujlwm hnyav
LAG LUAM:
Kev tsim kho vaj tse, roj & roj av, kev tsim hluav taws xob, cov khoom siv hnyav
HOM HLAU:
Hmoov hlau, hlau-cored
TAM SIM NO:
HN-590, SWX 120, SWX 150
TAM SIM NO:
Tam Sim No Ncaj Qha Electrode Positive (DCEP), Tam Sim No Ncaj Qha Electrode Negative (DCEN), Alternating Current (AC)
CIA:
Cov khoom yuav tsum tau khaws cia rau hauv qhov chaw qhuav, kaw, thiab hauv nws lub thawv qub uas tseem zoo li qub
AWS KEV SIB THAM:
COV KHOOM SIV TXUJ CI IB TXWM:
COV KEV UA HAUJ LWM IB TXWM:
Kev tswj cov txheej txheem vuam kom zoo - suav nrog kev ua kom sov ua ntej thiab qhov kub ntawm qhov sib tshuam - yuav tseem ceeb heev nyob ntawm hom thiab tuab ntawm cov hlau uas raug vuam.
Cov kev ntsuas tsuas yog muab rau cov ntaub ntawv xwb. Txhua tus nqi yog kwv yees xwb. Qhov hluav taws xob zoo tshaj plaws yuav txawv (feem ntau ± 2 volts) nyob ntawm qhov kev xaiv ntawm cov dej ntws, cov khoom siv tuab, kev tsim pob qij txha, thiab lwm yam hloov pauv tshwj xeeb rau daim ntawv thov.
Ib yam li ntawd, qhov tseeb ntawm qhov tso dej tawm yuav txawv nyob ntawm qhov kev xaiv ntawm cov dej ntws thiab lub taub hau tiv tauj mus rau qhov deb ua haujlwm.
