E6012 yog lub electrode dav dav uas muaj cov yam ntxwv zoo heev, tshwj xeeb tshaj yog rau cov ntawv thov uas tsis haum.
E6012 muaj qhov arc zoo, ruaj khov thiab ua haujlwm ntawm cov dej ntws siab nrog qhov tsis tshua muaj spatter. Siv tau ntau yam, E6012 siv tau nrog ob qho tib si AC thiab DC fais fab.
Cov Kev Siv Ib Txwm Muaj: cov cuab yeej ua liaj ua teb, kev kho dav dav, kev tsim khoom siv, rooj tog hlau, hlau dai kom zoo nkauj, hlau ntawv, cov thoob dej
AWS specification: AWS A5.1 E6012
JIS Cov Lus Qhia: D4312
Lwm Cov Lus Qhia: DIN E4321 R3
I. COV NTAWV THOV:
Cov khoom siv hlau tsis hnyav, Cov qhov rai hlau thiab cov hlau ci thiab laj kab, cov hlau thawv, vuam cov kav dej tsis muaj galvanized, cov qauv hlau rau tsev, cov rooj zaum hlau thiab cov rooj, cov ntaiv hlau thiab lwm yam hlau tsis hnyav thiab lwm yam.
II. PIAV TXOG:
Ib qho electrode vuam hlau uas siv tau rau txhua qhov chaw, uas muaj cov yam ntxwv zoo ntawm kev sib xyaw thiab kev nkag mus tau zoo. Zoo rau kev txuas cov qhov sib txawv ntawm cov haujlwm tsis zoo. Siv tau yooj yim rau ntawm cov hlau sib dua thiab cov qauv hlau hnyav. Cov hlau vuam muaj cov duab du, puag ncig zoo thiab sib npaug nrog cov nplaim sib zog. Cov fillets yog convex tsis muaj kev txiav hauv qab. Nws qhov kev ua haujlwm txhua qhov chaw, ua ke nrog cov hlau vuam uas khov sai thiab lub zog arc ua rau nws yog ib qho electrode zoo tagnrho rau kev ua haujlwm thiab qhov chaw. Cov yam ntxwv zoo heev thaum vuam ob qho tib si ntsug thiab ntsug. Cov slag tawm yooj yim heev thiab feem ntau nws tus kheej tso tawm.
III. COV LUS CEEV TXOG KEV SIV:
Ua tib zoo saib xyuas kom tsis txhob siv hluav taws xob ntau dhau. Kev vuam siv hluav taws xob ntau dhau tsis yog tsuas yog ua rau lub zog X-ray tsis zoo xwb, tab sis kuj ua rau muaj kev tawg ntau ntxiv, txiav tsis raug thiab tsis txaus npog slag.
Ua ntej siv, ua kom cov electrodes qhuav ntawm 70-100 degrees C li 30-60 feeb. Kev nqus dej ntau dhau yuav ua rau siv tsis tau zoo thiab tej zaum yuav ua rau muaj qhov porosity.
Kev ziab ntau dhau ua ntej siv ua rau muaj kev nkag mus tsawg dua thiab kub dhau ntawm lub electrode
