Flux Core core yog qhov tsis muaj nuj nqis tsis yog rau nws cov versatility thiab kev ua tau zoo, tab sis kuj rau nws lub peev xwm los ua cov khoom siv muaj zog, ruaj khov. Lub zog ntawm flux tseem ceeb weld nyob ntawm ntau yam, suav nrog hom kev siv hlau flux, vuam cov txheej txheem, thiab kev yoog raws rau cov qauv zoo. Thaum tua tau zoo, Flux Core Vuam tuaj yeem tsim cov pob qij txha uas muaj zog dua li) lub hauv paus pib dua) lub hauv paus pib, kev lag luam, thiab hnyav {2} lub luag haujlwm thov.
Qhov tseem ceeb uas txiav txim siab flux core weld lub zog
1. Lub zog xaim hlau
Flux corek hlau nws tus kheej yog tus tsav tsheb hauv Weld lub zog. Manufacturers Tsim cov xov hlau kom phim lossis tshaj lub tensile zog ntawm cov khoom siv ua haujlwm sib xws:
Cov hlau me me hlau (piv txwv li, e71t {4 4}} 8}}} {}} Qhov no txhais tau tias cov weld feem ntau yuav ua tsis tau nyob rau hauv lub hauv paus hlau (tsis yog weld) nyob rau hauv lub zog weld) nyob rau hauv lub zog loj-muaj kev sib koom ua ke ntawm lub zog sib koom tes.
Siab - lub zog siv xov hlau (piv txwv li, e81t1 {}}}}}}}}} pasis muaj zog ntawm 80,000 psi lossis siab dua. Cov hlau no suav nrog Alloys zoo li npib tsib xee los txhim kho txoj kev nruj, ua rau lawv zoo tshaj plaws rau cov ntawv thov zoo li cov choj girders lossis crane sib xyaw.
Stainless hlau xaim (piv txwv li, e308LT1-1) phim rau corrosion tsis kam thiab lub zog ntawm stainless hlau lub hauv paus hlau (ncig ntawm 80,000 psi) thiab ib puag ncig hnav.
Xaiv lub xaim nrog lub zog ua kom muaj zog sib npaug lossis ntau dua ntawm cov hlau hauv weld yuav tsis yog qhov txuas "tsis muaj zog" hauv cov qauv.
2. Weld nkag
Flux tseem ceeb vuam ua rau muaj kev tsom xam, siab {{}} kub arc uas ua kom sov ntau dua li lwm cov txheej txheem xws li cov khoom sib tw sib txuas. Qhov tob tob ua rau muaj kev sib zog ua ke loj dua Fusion cheeb tsam, qhov twg Weld hlau thiab lub hauv paus hlau intermix ntawm theem molecular. Ib tus weld nrog tag nrho nkag (txuas ntxiv los ntawm tag nrho cov tuab ntawm lub hauv paus hlau) faib kev ntxhov siab, tiv thaiv tsis ua haujlwm ntawm Weld kab.
Piv txwv li, thaum vuam ¼ - nti me me steel coreker hlau (0.045 nti inch) thiab yog weld yuav nkag rau 100% ntawm lub phaj tuab. Qhov no ua kom cov sib koom ua ke no tuaj yeem ris tau tib yam li cov hlau ib puag ncig yam tsis muaj kev tawg lossis tawg ntawm Weld.
3. Kev ywj pheej los ntawm kev tsis xws luag
Lub zog yog undermined los ntawm weld tsis xws luag, thiab flux core vuam yuav pab txo ntau yam teeb meem:
Cov tub ntxhais hluas flux ua raws li tus deoxidizer, txo qhov porosity (roj npuas) uas tsis muaj zog ntawm Weld.
Welded kom zoo flux tseem ceeb masters (txawm hais tias tus kheej {{0} {{
Lub ntsej muag txhaws ntxiab ntxiab ntxiab, tiv thaiv lawv kom tsis txhob muaj kev suav nrog weld.
Txawm li cas los xij, tsis xws luag zoo li tsis tiav Fusion (yog tias ARC tsis tau yaj lub hauv paus pib txaus) lossis tawg (los ntawm kev ua kom txias) yuav txo lub zog. Cov tshuaj welders tsom rau kev tswj hwm ruaj khov ntawm arc ntev, kev mus ncig ua si nrawm, thiab cov lus qhia kom sov kom tsis txhob muaj qhov tsis txaus ntseeg.
4. Puag hlau sib xyaw
Flux Core Venty Corerd lub zog kuj yog nyob ntawm txuam nrog cov hlau rau cov hlau hauv paus. Vuam siab - lub zog steel nrog lub qes- lub xaim hluav taws xob yuav ua rau muaj lub zog weld, txawm tias cov hlau yog cov khoom lag luam zoo. Piv txwv li:
Siv 70,000 psi hlau rau 100,000 psi siab {{}} lub zog steel yuav ua rau lub weld kom ua tsis tiav.
Vuam aluminium nrog tus hlau xaim tsim ib lub ntsej muag me me, sib koom ua ke tsis muaj zog vim yog xim hlau tsis sib haum.
Xaiv cov hlau tsim rau cov hlau hlau (piv txwv li, txhuas-} Cov hlau stainless muaj txiaj ntsig zoo thiab qhia txog cov hlau lub zog ua rau muaj zog.
Lub Zog Pivcus: Flux Core Vs. Lwm qhov chaw vuam
Flux core vuam tuav nws tus kheej tawm tsam lwm txoj kev nrov thaum nws los dag zog:
Piv rau Mig vuam: Ob qho txheej txheem tsim cov welds muaj zog thaum siv cov hlau ua chaw ua haujlwm. Flux tseem ceeb tshaj plaws feem ntau muaj kev nkag mus tob, muab lawv me ntsis hauv cov khoom tuab. MIG tej zaum yuav muaj qhov zoo me ntsis hauv cov hlau nplaum me me, tab sis flux tseem ceeb lub zog yog sib piv rau cov kev ua haujlwm zoo tshaj plaws.
Piv rau lo lo lus vuam vuam: Flux tseem muaj zog rau cov khoom siv tuab, raws li cov hlau txuas ntxiv ua rau muaj kev tawm tshiab sib xws thiab tob dua. Pas vuam tuaj yeem tsim cov khoom siv muaj zog tab sis muaj ntau dua siab rau cov tes tsis muaj txiaj ntsig.
Piv rau lub vuam vuam: Tig welds yog meej meej tab sis muaj qis qis tus nqi. Flux tseem ceeb mab, thaum tsis tshua muaj kev zoo nkauj, muaj zog nyob rau hauv hnyav {{1} Lub luag haujlwm} kev nkag mus thiab cov fusion fusion zones.
Hauv kev sim cov txheej txheem, kom zoo tua flux tseem ceeb ntawm cov hlau me me uas feem ntau swb hauv lub zog ntawm lub zog "Niam Txiv Tsis Ua Haujlwm."
Tiag - Lub ntiaj teb lub zog ua tau zoo
Flux Core Vuam lub zog yog pov thawj hauv kev thov cov ntawv thov uas tsis ua haujlwm tsis yog ib qho kev xaiv:
Cov hlau txheem txheem txheem: choj, lub tsev ua ke, thiab crane booms cia siab rau cov khoom lag luam flux kom tiv taus cov khoom siv zoo, kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig, thiab kev ntxhov siab ib puag ncig. Flux Core Core Verse ntawm ib qho steel i {{nqaj yuav tsum tau txhawb ntau xyoo lawm, thiab cov qauv kev lag luam (xws li cov ntaub ntawv kev lag luam kom tau txais cov txheej txheem nruj.
Pipeline Vuam: Tus kheej {- shield flux tseem ceeb Wyrs koom nrog cov khoom lag luam hauv nroog Cov ntawv Welds no yuav tsum tiv thaiv bursting thiab corrosion, feem ntau kav 50+} xyoo nrog kev saib xyuas kom zoo.
Cov cuab yeej hnyav: Bulldozer hniav, thiab cov tshuab sib law ua ke yog nyob ntawm tus lej flux kom dhau kev cuam tshuam, puas tsuaj, thiab cov khoom hnyav. Welds nyob rau hauv cov cheebtsam no raug sim kom wallstand khoov, sib ntswg, thiab shear rog yam tsis tau tawg.
Automotive thiab cov tsheb thauj khoom: Cov tsheb thauj khoom thiab cov kev sib tw tsheb ciav hlau welded nrog flux tseem ceeb yuav tsum txhawb nqa payloads ntawm 10, {} phaus. Kev soj ntsuam kev sib tsoo qhia cov cuab yeej hauv Welds feem ntau tuav tau zoo dua li cov pob qij txha hauv kev sib tsoo.
Maximizing Flux Core Weld Lub Zog
Txhawm rau kom Flux tseem ceeb Wulls ncav cuag lawv lub zog tag nrho, ua raws li cov kev coj ua zoo tshaj plaws:
Xaiv cov xaim xaim zoo: phim cov hlau lub tensile lub zog thiab alloy rau lub hauv paus hlau.
Tswj tshav kub tawm: dhau cua sov weakens cov cua sov -} bein cuam tshuam thaj chaw (Haz); Tsawg heev ua tsis tiav fusion. Kho voltage thiab hlau pub ceev rau cov hlau tuab.
Ntxuav lub hauv paus hlau: Tshem cov xeb, roj, lossis pleev xim (txawm hais tias flux zam lub teeb ua kom tsis txhob muaj qhov dav.
Preheat tuab cov hlau: rau cov hlau dhau ½ nti, preheating rau 250-400℃f txo cov nqi cua txias, tiv thaiv cov kab nrib pleb hauv lub taub hau.
Soj ntsuam rau tej yam tsis xws luag: Kos rau porosity, kab nrib pleb, lossis hauv qab ntoo tom qab vuam. Zom tawm cov tsis xws luag me me thiab re - Weld yog tias xav tau.
Tag
Flux tseem ceeb vuam yog muaj peev xwm ua tau los ntawm kev ua tau muaj zog heev wels {} {} Lub luag hauj lwm {}} Thaum ua kom raug. Nrog tus xaim xaim xis, cov txheej txheem kom tsim nyog, thiab saib xyuas zoo, ua kom muaj zog ntawm lub hauv paus, faib tsis tau kev poob siab hauv lub nra.
Nws lub zog, ua ke nrog nws cov kev yoog raws li cov kev xaiv sab nraum zoov thiab cov txiaj ntsig zoo, ua rau muaj kev ntseeg siab rau cov haujlwm uas ntseeg tau thiab lub siab yog qhov tseem ceeb. Txawm hais tias koom nrog cov dej pheebseline, lossis kho cov tshuab ua haujlwm hnyav, flux tseem ceeb ntawm lub zog yuav tsum tau ua kom tau txoj haujlwm tiav.
