E6012 yog lub hom phiaj dav dav electrode uas muaj cov yam ntxwv zoo heev, tshwj xeeb tshaj yog rau cov ntawv thov tsis zoo.
E6012 muaj qhov zoo, ruaj khov arc thiab ua haujlwm ntawm cov hluav taws xob siab nrog qis qis.Kev siv ntau yam, E6012 tuaj yeem siv nrog ob lub zog AC thiab DC.
Daim ntawv thov: kev ua liaj ua teb, kev kho dav dav, machinery fabrication, hlau rooj tog, ornamental hlau, ntawv hlau, tso tsheb hlau luam
AWS A5.1 E6012
JIS Specification: D4312
Lwm yam Specification: DIN E4321 R3
I. APPLICATIONS:
Cov ntaub ntawv me me, steel qhov rais thiab hlau grills thiab laj kab, thawv steel, vuam ntawm cov kav dej tsis zoo, steel qauv rau tsev, steel rooj zaum thiab rooj, steel ladders thiab lwm lub teeb ntsuas me me steels thiab lwm yam.
II.DESCRIPTION:
Ib txoj hauj lwm dav dav siv rau Shielded Hlau Arc Vuam electrode nrog cov yam ntxwv zoo fusion thiab nkag mus.Zoo haum rau txuas qhov sib txawv ntawm kev ua haujlwm tsis zoo.Kov yooj yim ntawm lub teeb ntawv hlau nrog rau cov qauv steel hnyav.Weld muaj du, zoo-puab thiab txawm hlaws dai nrog ze rippled nto.Cov fillets yog convex tsis muaj undercutting.Nws tag nrho txoj haujlwm ua haujlwm, ua ke nrog lub nrawm nrawm nrawm hlau thiab lub zog arc ua rau nws zoo tagnrho electrode rau kev cob qhia thiab chaw ua haujlwm.Cov yam ntxwv zoo heev thaum welding ob qho tib si vertically-up thiab vertically-down.Lub slag tuaj tawm yooj yim heev thiab yog feem ntau nws tus kheej tso tawm.
III.CEEB TOOM RAU SIV:
Ua tib zoo saib kom tsis txhob dhau qhov ntau ntawm cov dej ntws zoo.Vuam nrog ntau dhau tam sim no tsis tsuas yog txo qis X-ray soundness, tab sis kuj ua rau muaj kev sib tsoo, hauv qab-txiav thiab tsis txaus slag npog.
Qhuav cov electrodes ntawm 70-100 ° C rau 30-60 feeb ua ntej siv.Kev nqus dej ntau dhau txo qis kev siv tau thiab tuaj yeem ua rau qee qhov porosities.
Kev ziab ntau dhau ua ntej siv ua rau tsawg dua hauv kev nkag mus thiab overheating ntawm electrode
