AWS A5.13 ECoCr-A Hard-facing Manual electrode weld fabrication jointing
GEH-SL6 yog Cobalt-based surfacing electrode raws li AWS A5.13 ECOCRA-A tus qauv.Nws yog tsuas yog siv rau surfacing kub thiab siab siab li qub, kub shear hniav, cav li qub, turbine hniav, thiab lwm yam. Nws yuav siv tau rau ob leeg AC thiab DC.Nws raug nquahu kom siv DC thim rov qab txuas thiab electrode zoo txuas.Ruaj khov arc, zoo slag npog, zoo zoo nkauj.Cov txheej txheej saum npoo muaj cov khoom siv zoo heev hauv qhov kub thiab txias hauv qab 800 ℃, thiab muaj kev tiv thaiv corrosion zoo, oxidation tsis kam thiab tsis kam hnav intermetallic.Cov txheej txheej saum npoo tuaj yeem raug machined.
Daim ntawv thov & Standard
GEH-SL6 yog ib hom surfacing vuam rau lub cav valve, turbine hniav, siab kub thiab siab siab valve, kub forging tuag thiab lwm yam kub hnav tsis kam thiab corrosion kuj qhov chaw.Nyob rau hauv cov txheej txheem welding, thiaj li yuav tsum tau ruaj khov ua ke nrog lub substrate, nws yog ib qho tsim nyog yuav tsum tau weld tob tob.Yog li ntawd, tsuas yog luv luv arc vuam txoj kev tuaj yeem txais yuav.Thib ob, txhawm rau daws qhov teeb meem ntawm lub pas dej sib sib zog nqus thiab cov khoom siv ntau dhau melting rau hauv qhov vuam thaum lub sij hawm luv luv arc vuam, tus nqi dilution yog siab.Qhov tsis muaj cov khoom siv hauv cov txheej txheem vuam txo cov teeb meem hnav tsis kam.Yuav tsum siv txoj kev ntawm ntau yam, multi-layer surfacing.Nyob rau hauv txoj kev no, tsis tsuas yog cov khoom siv tau zoo thiab hnav tsis kam nyob rau hauv backsurfacing txheej nce txheej los ntawm txheej.Ntxiv mus, thawj ob peb txheej ntawm surfacing kuj ua lub luag haujlwm ntawm cov txheej txheem hloov pauv, txo qhov tawg los ntawm qhov sib txawv ntawm thermal expansion coefficient ntawm ob txheej uas nyob ib sab.Meanwhile, txoj kev ncaj txoj kev txav, ntses nplai txav txoj kev, herringbone txav txoj kev los yog luv arc agitation txav txoj kev yuav tsum tau saws.
Nta
Qhov no yog titanium calcium txheej cobalt puag surfacing electrode, haum rau DC thim rov qab kev twb kev txuas, cov surfacing hlau tseem tuaj yeem tuav tau zoo hnav tsis kam thiab corrosion kuj ntawm 650 ℃, cuam tshuam tsis kam thiab txias thiab kub qaug zog.Yuav siv tau nyob rau hauv qhov yuav tsum tau ntawm ib ncig ntawm 650 ℃ ua hauj lwm tseem tuaj yeem tuav tau zoo hnav tsis kam thiab qee yam corrosion kuj, nrog rau qhov cuam tshuam thiab txias thiab kub staggered qhov chaw, tuaj yeem ua haujlwm zoo.
