AWS A5.23: ECF3 Submerged Arc Welding Wire Arc Cored Wires Low-Alloy Steel

CATEGORY:

AWS A5.23: ECF3 Submerged Arc Cored Wires Low-Alloy Steel

DESCRIPTION:

AWS A5.23: ECF3 is a low-alloy composite metal-cored wire electrode for submerged arc welding in high strength applications.Thiab nws ua tau raws li AWS A5.23 chemistry F3, thiab yog tsim los rau qib tensile zog siab tshaj 100 ksi.

NTA & Cov txiaj ntsig:

Hlau-cored hlau tuaj yeem muab cov txiaj ntsig zoo dua piv rau cov xaim khoom ntawm qhov sib piv amperages

Hlau-cored xov hlau muaj dav nkag mus rau cov ntaub ntawv sib piv rau cov khoom siv ntawm cov khoom siv vuam sib piv

Weld deposit chemical muaj pes tsawg leeg yuav tsum tau zoo tib yam rau cov EF3 khoom nyob ntawm tej

Weld deposit chemical muaj pes tsawg leeg muaj tsawg dua 1% npib tsib xee

Zoo heev uas tsis tshua muaj kub cuam tshuam toughness nyob rau hauv ob qho tib si as-welded thiab kev ntxhov siab-relieved tej yam kev mob

Muab lub peev xwm los ua kom nrawm nrawm rau kev txhim kho kev tsim khoom

Pab tiv thaiv kev kub nyhiab thaum vuam ntawm cov dej ntws siab ntawm cov hauv paus hla thiab cov ntaub ntawv nyias nyias.

Tsim nyog raws li kev ua tau zoo dua hauv ntau daim ntawv thov tam sim no siv EF3 khoom hlau

Tsim nyog siv rau hauv daim ntawv thov roj qaub qhov kev ntxhov siab corrosion tawg vim hydrogen-sulfide yog ib qho kev txhawj xeeb

Pab txo qis txoj kev pheej hmoo ntawm kev tawg hauv cov ntawv thov tseem ceeb thiab kev pabcuam hnyav

Kev lag luam:

Kev tsim qauv tsim, roj & roj, tsim hluav taws xob, khoom siv hnyav

KHOOM HOM:

Hlau-hmoov, hlau-cored hlau

Tam sim no:

HN-590, SWV 120, SWX 150

Tam sim no:

Irect Current Electrode Positive (DCEP), Direct Current Electrode Negative (DCEN), Hloov Tam Sim No (AC)

KHOOM:

Cov khoom yuav tsum tau muab khaws cia rau hauv qhov chaw qhuav, ib puag ncig, thiab hauv nws qhov qub ntim khoom

TYPICAL MECHANICAL PROPERTIES:

TYPICAL OPERATING PARAMETERS:

Kev tuav cov txheej txheem vuam kom zoo - suav nrog cov cua sov ua ntej thiab qhov sib txawv ntawm qhov kub thiab txias - tej zaum yuav yog qhov tseem ceeb nyob ntawm seb hom thiab tuab ntawm cov hlau tau welded.

Parameters yog muab rau cov ntaub ntawv xov xwm nkaus xwb.Tag nrho cov nqi yog kwv yees.Qhov zoo tshaj plaws voltage yuav txawv (feem ntau ± 2 volts) nyob ntawm seb qhov kev xaiv ntawm flux, cov khoom thickness, kev sib koom tsim, thiab lwm yam txawv txawv rau daim ntawv thov.

Ib yam li ntawd, qhov nyiaj tso tawm tiag tiag tuaj yeem sib txawv nyob ntawm qhov kev xaiv ntawm flux thiab kev tiv tauj rau kev ua haujlwm nyob deb.
