Vuam cov kev sib tw txhuas presents vim nws cov siab thermal conductivity, qis melting point (1,221℃txheej uas ua rau nws nto. Tsis zoo li cov hlau, uas tuaj yeem muab welded nrog ntau cov electrodes, txhuas yuav tsum muaj cov electrodes tshwj xeeb thiab kev puas tsuaj-} welds dawb welds. Kev xaiv ntawm electrode nyob ntawm lub vuam txoj kev vuam, tab sis tungsten electrodes (rau Mig Vuam) yog thawj txoj kev xaiv, txhua tus txiav rau cov ntawv thov tshwj xeeb.
TUNGTEN Electrodes: Lub Pob Txheem ntawm Tig Vuam rau Aluminium
Tungsten inert roj (tsov) vuam yog ib qho ntawm feem ntau cov qauv rau kev siv vuam aluminium, thiab nws tso cai rau tsis yog}}} Consumable tungsten elecsten electst electst electst electst electst electst electst electst electst electst electst electst electst electst electst electst elecstodes los tsim lub arc. Tungsten yog qhov zoo tshaj vim tias nws muaj qhov siab heev li qub (6,492 degree), cia nws los tswj nws cov duab thaum tsim kom muaj cua sov kom yaj.
Hom Tungsten Electrodes rau Aluminium:
Ntshiab tungsten (WP): Qhov no yog qhov kev xaiv pib nrog 99.5% Tungsten Cov Ntsiab Lus. Nws ua haujlwm tau zoo rau AC Tig vuam (tus qauv rau txhuas) vim tias nws ua ib qho ruaj khov nyob rau hauv lwm qhov tam sim no, uas pab ua txhaum txhuas lub oxide txheej. Txawm li cas los xij, ntshiab tungsten muaj qis dua tam sim no- nqa tau cov peev xwm thiab ntau dua li 1/8 nti) thiab lub teeb {6 {
Zirconiated Tungsten (WZR): Sib txuam nrog 0.15-0.4% Lub Zirconium, Qhov No Electrode, lub neej zoo dua li cov ntshiab tungsten. Nws tswj tau cov lus qhia ntse, uas yog qhov muaj txiaj ntsig zoo rau cov vuam vuam ntawm cov hlau nyias nyias zoo li cov hlua tsheb lossis ib qho kev ua lag luam. Nws kuj tiv taus kev paug los ntawm txhuas, txo qhov xav tau rau cov lus qhia nquag tu.
Thia tungsten (wt): ib zaug nrov, siab tungsten muaj 1-2% thorium (lub caij xov tooj cua). Nws muab AR zoo heev thiab muaj peev xwm tam sim no, ua rau nws haum rau tuab txhuas. Txawm li cas los xij, vim muaj kev pheej hmoo txaus ntshai los ntawm cov plua plav hauv cov plua av
LanThanous Tungsten (WL): Niaj hnub nimno: Tsis yog - Txoj Cai Lwm Tiam, nws yog txuam nrog 1-2% Lanthhant. Nws muaj cov arc zoo tshaj plaws, muaj peev xwm tam sim no, thiab lub neej ntev, ua haujlwm zoo rau ob qho tib si Ac thiab DC Tig Vuam ntawm Aluminium. Nws yog veratile txaus rau nyias thiab tuab txhuas, ua nws txoj kev xaiv zoo rau cov kws tshaj lij.
Cov kev txiav txim siab tseem ceeb rau tungsten electrodes hauv txhuas vuam:
Cov ncauj lus taub: Rau AC Tig vuam, ib daim taub ntses (tsim los ntawm melting qhov kawg ntawm lub electrode) yog nyiam. Cov ncauj lus zais faib faib cov txheej txheem oxide, thiab txo lub ntsej muag.
Qhov loj me: cov diam me me (1 / 16-3 / 32 nti) yog siv rau cov nyias nyias, thaum lub taub loj dua (1-3 / 16 nti) lis cov khoom siv tuab thiab nce ntxiv.
Polarity: Txhuas Tig Vuam yuav tsum AC Tam sim no los ntxuav cov txheej oxide (ntawm "kev tu vajtse" ntawm kev hloov pauv tam sim no) thiab yaj cov hlau. Tungsten Electrodes tsim rau AC siv (zoo li WP, WL, thiab WL) ua tau zoo tshaj plaws hauv kev teeb tsa no.
Cov thawv ntim cov hluav taws xob: Cov kev xaiv muaj kev siv tau rau MIG thiab STAT VUAM
Rau MIG (hlau inert roj) thiab lo vuam vuam (tab sis tsis muaj zog vuam Cov hluav taws xob no yog tsim los ntawm alloys alloys kom phim lub hauv paus hlau qhov muaj pes tsawg leeg, ua kom muaj kev sib xyaw thiab lub zog.
Mig welding electrodes rau txhuas:
Mig vuam ntawm txhuas siv tas mus li, consumable electrode (ib lig xaim xaim) uas tau pub los ntawm kev sib tsoo phom. Lub hauv hluav taws xob melts los ua tus weld hlaws, yog li nws cov lus yuav tsum phim lub hauv paus txhuas kom tsis txhob tawg lossis tsis muaj zog.
1100 Aluminium Electrode: LAWV 99% Aluminium, Qhov no yog cov neeg ua haujlwm muab tub lim. Nws yog mos thiab ua kom haum rau vuam 1100 thiab 3003 alloys alloys (siv nyob rau hauv cov ntawv hlau thiab khoom dai kom zoo nkauj). Txawm li cas los xij, nws muaj lub zog tsawg thiab tsis zoo corrosion tsis kam, txwv nws siv los tsis {}} cov qauv kev siv.
4043 aluminium electrode: qhov no yog ib qho ntawm cov nyiam tshaj plaws mig electrodes rau txhuas. Nws yog txuam nrog silicon (5-6%), uas txo nws lub taw tes melting, txhim kho fundity, thiab txo kev tawg. Nws ua haujlwm tau zoo nrog 6061, 6063, thiab 3003 aluminium-}}} cov khoom siv, thav duab, thiab tsheb kho tsheb. Cov sillicon tseem pab rau cov khoob, ua kom nws zam txim rau cov pib tshiab.
5356 txhuas electrode: txuam nrog magnesium (4.5-5.5%), cov electrode no tsim muaj zog, corrosion {{} {reawant welds. Nws yog qhov zoo tagnrho rau vuam 5052, 5083, thiab 6061 txhuas, uas tau siv rau hauv cov ntawv thov marine, cov hlab ntsha, thiab cov qauv txheej txheem. Nws muaj ntau dua tensile muaj zog tshaj 4043 tab sis yog ntau dua nquag tawg yog tias tsis welded zoo, yuav tsum ceev faj kom ceev faj.
Pas welding cov electrodes rau txhuas:
Pas vuam (smws) yog qhov tsis tshua muaj rau txhuas vim flux txheej tuaj yeem ntxiab hydrogen, ua rau muaj ntau yam dej hiav txwv. Txawm li cas los xij, nws yog siv nyob rau hauv kev kho cov teb uas mews lossis cov khoom siv tawv tsis muaj. Aluminium Muab cov hluav taws xob muaj cov txheej txheej flux uas tiv thaiv cov weld pas dej ua ke.
E 4043 - 16}: flux - Cov tub muab tub lim rau cov 4061 thiab 3003 Aluminium. Lub flux tshem tawm cov oxides thiab ua cov nplais tiv thaiv, tab sis nws yuav tsum tau tu tom qab vuam los tiv thaiv corrosion.
E 5356 - 16: flux - Lub zog yog siv rau high {{} {tsis tshua muaj welds rau 5052 thiab 6061 txhuas. Nws yog rhiab heev rau noo noo dua e 4043 - 16, yog li nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav kom tsis txhob muaj qhov porosity.
Vim li cas txhuas yuav tsum muaj cov electrodes tshwj xeeb
Aluminium lub zog tshwj xeeb ua rau Generic Steel Electrodes Inceptive:
Oxide txheej: Aluminium sai sai cov qauv oxide txheej (alumina) uas melts ntawm 3,700℃{{4} kub ntau dua aluminium. Tungsten Electrodes nyob rau hauv Tig vuam, Paired nrog AC tam sim no, zoo li 4043) muaj silicon kom yaj oxides thaum vuam.
Thermal conductivity: Txhuas ua cua sov 5 zaug sai dua li cov hluav taws xob uas muaj cov hlau me me (zoo li 4043) kom tsis txhob noj mov txias lossis tsis tiav fusion.
Kev muag muag: Txhuas yog mos, yog li cov hluav taws xob ua haujlwm yuav tsum sib phim nws qhov kev sib txuas los tiv thaiv kev cuam tshuam welds los ua. Aluminium -} raws li fille (es tsis yog hlau) kom lub weld tuaj yeem feld tuaj yeem feld tuaj yeem flex nrog cov hlau hauv paus.
Yuav ua li cas xaiv cov khoom siv tau rau koj cov phiaj xwm Aluminium Alines
Txoj Kev Vuam: Tig Vuam yuav tsum tsis txhob -} Consumable Tungsten Electrodes (WL lossis WZR rau feem ntau cov ntawv thov). Mig vuam siv cov kev siv Aluminium sau cov hluav taws xob (4043 rau kev siv dav dav, 5356 rau lub zog). Lo vuam siv flux -}}}} coated txhuas electrodes (e {} rau kev kho).
Puag txhuas alloy: phim cov electrode rau lub hauv paus kav hlau. Piv txwv li, siv 4043 nrog 6061 Aluminium, thiab 5356 nrog 5052 txhuas, kom paub tseeb tias muaj peev xwm thiab lub zog.
Cov Khoom Thickness: Rau nyias txhuas (<1/8 inch), use pure tungsten or WZr (TIG) or 4043 (MIG). For thick aluminum (>1/4 nti), siv lanbthhanated tungsten (Tig) lossis 5356 (MIG) rau lub zog siab dua.
Daim Ntawv Thov: Cov haujlwm ua haujlwm lossis sab nraum zoov cov haujlwm xav tau corrosion {} {} {} Cov txheej txheem tsis tuaj yeem siv 1100 lossis 4043.
Cov lus qhia rau kev siv Altrodes
Ntxuav cov nplaim dej: tshem tawm cov txheej oxide nrog lub stainless - kub txhuam (tshwj tseg rau cov electrode ib qho muaj zog arc thiab tiv thaiv porosity.
Siv cov khoom tiv thaiv kom zoo: rau Tig thiab mig vuam, siv siab {{}}}}}}}}}}% ua pas dej ua ke los tiv thaiv cov weld pas dej sib tsoo. Argon pab tswj lub arc thiab txhim kho cov kev ntxuav tu ntawm txhuas.
Zam txhob overheating: Aluminium qis melting taw tes txhais tau tias nws tuaj yeem warp yooj yim. Siv cov electrode me me thiab qis tshaj plaws amperage xav tau kom yaj cov hlau, thiab txav mus sai rau txo cov lus qhia sov.
Tswj cov mob electrode, kom lub tig vuam, kom lub tungsten taub huv -}} yuav ua rau muaj kev tsis txaus. Rau mig vuam, xyuas kom cov hlau pub dawb yog teeb kom tsis txhob noog {{}} zes (Tangling) hlau.
