Koj puas tuaj yeem Weld Aluminoy Alloy

Txhuas alloys, ua kev zoo siab rau lawv lub zog tshwj xeeb {{}} qhov hnyav tsis kam, thiab ntau yam kev tsim kho, thiab cov neeg siv khoom siv hluav taws xob. Cov lus nug tseem ceeb hauv kev tsim khoom thiab kho cov voj voog yog: Koj puas tuaj yeem Weld Aluminium Alloy? Cov lus teb yog lees paub, tab sis nrog kev txiav txim tshwj xeeb. Tsis zoo li cov hlau, aluminium alloys nthuav qhia cov kev sib tw tshwj xeeb thaum lawv muaj cov txheej txheem zoo, tseem muaj cov kev paub zoo, thiab cov khoom siv zoo me ntsis tuaj yeem ua tiav. Cov ntawv no tshawb txog qhov weldability ntawm txhuas alloys, cov nyom tseem ceeb, thiab kev sib tw vuam cov kev daws teeb meem.
Txhuas alloys sib txawv hauv cov ntawv qhia hauv qab los ntawm ferrous hlau nyob rau hauv txoj kev uas cuam tshuam vuam. Lawv lub ntsiab lus qis qis (kwv yees li 580-660 degree, piv rau 1538℃rau cov hlau) yuav tsum tau kho kom sov. Txheej Oxide Oxide (alumina, al₂o₃) cov ntaub ntawv tam sim ntawd rau saum npoo thaum raug huab cua; Cov oxide no tau muaj qhov taw tes melting ntawm 2072 degree- deb dua li txhuas nws tus kheej}}} posing ib qho laj thawj yog tias tsis muab tshem tawm kom raug. Tsis tas li ntawd, txhuas lub siab thermal conductivity ua rau kub kub kom tsis txaus siab sai ntawm weld cheeb tsam, xav kom muaj cua sov siab dua los tswj cov pas dej ruaj khov. Cov xwm txheej no, sib xyaw ua ke nrog Alloy-, cov ntsiab lus tooj liab hauv 2000-series alloys), yuav tsum tau siv vuam vuam vuam.
Weldability ntawm cov txhuas alloy series
Aluminium alloys tau categorized los ntawm lawv cov ntsiab lus tseem ceeb, thiab lawv cov veDability sib txawv:
1000 series (kev lag luam ntshiab txhuas)
Cov alloys (piv txwv li, 1100, 1050, 1050) muaj 99% nrog kev siv tsawg tsawg. Lawv tau ua tau zoo rau Weldability vim lawv lub zog qis thiab tsis muaj cua sov-}} Cov khoom siv kho tau:
• Kev vuam txoj kev vuam GTAW los tswj kev nyias seem, thaum GMAW yog qhov ua tau zoo rau cov khoom siv thicker.
• Cov kev txiav txim siab tseem ceeb: txheej oxide yooj yim tswj tau yooj yim tu thiab muab tub lim hlau xaiv (piv txwv li, 1100 lossis 4043 muab tub lim). Tsis muaj tus xa ntawv - Weld Kev Kho Cua sov yog xav tau, raws li cov alloys tsis yog {}}}} nrhiav tau.
• Cov ntawv thov: Welded hauv kev hloov hluav taws kub, cov khoom siv hniav zoo nkauj, thiab cov hluav taws xob.
3000 series (txhuas - manganese)

• Cov kev sib tw uas: Magnesium tuaj yeem cais tawm hauv pas dej Weld, nce kev phom sij ntau. Cov tub lim hlau ua haujlwm zoo li 5356 (magnesium- nplua nuj) lossis 4043 (silicon- nplua nuj) yog siv los sib npaug.
• Tswj: Zam kev ua kom sov ntau dhau; tswj txoj kev taug kev ncig uas txwv tsis pub ntev yaj. Tshaj tawm -} Weld tu tshem tawm cov kab mob blux kom txuag tau corrosion tsis kam.
6000 series (txhuas -} silicon - Magnesium)
Thaum tshav kub kub -} Cov khoom siv kho tau yooj yim (piv txwv li, 6061, 6063) Ua ke, kev sibntsuam mg₂si precipitates rau lub zog. Lawv muaj cov heldability me me:
• Kev vuam Txoj Kev: GTAW thiab GMAW nrog 4043 muab tub lim (silicon pab tiv thaiv kom tsis txhob tawg).
• Cov kev sib tw nyuaj: Vuam tuaj yeem soften cov cua sov -}}: vim yog nag lossis daus. Tshaj tawm - Weld Temper Kev Kho Mob (T6 Tempering Kev Kho Mob (Kev daws Annealing + Laus) tuaj yeem tsim lub zog hauv cov ntawv thov tseem ceeb.
• Cov kev thov: welded hauv cov xwm txheej tsheb, cov tsheb kauj vab, thiab cov qauv nkhaus, qhov twg muaj txiaj ntsig ntawm lub zog thiab weldability xav tau.
2000 thiab 7000 Series (tshav kub kub (kub- kev kho kom haum siab {}} muaj zog alloys)
Cov alloys (piv txwv li, 2024, 7075) tau ntxiv dag zog los ntawm tooj liab (2000 series) lossis zinc (7000 series) thiab muab rau ultra} Lub zog siab, ua rau lawv tseem ceeb hauv aerospace. Txawm li cas los xij, lawv weldability yog neeg pluag:
• Cov kev sib tw: nquag thab cov tawg thiab khaus embrittlement. Tooj liab hauv 2024 txhawb kev txhim kho kev txhim kho, thaum zinc hauv 7075 nce cov nyom tawg.
• Txwv cov vuam siv tsawg tsawg: VUAM TSIS TAU siv rau cov kev sib koom ua ke. Hloov chaw, tshuab nrawm nrawm (rivets, bolts) lossis cov nplaum sib txuas lus yog qhov xav tau. Thaum vuam yog qhov tsim nyog (piv txwv li, kev kho), cov txuj ci tshwj xeeb xws li kev sib txhuam (FSW) {}}
Cov Txheej Txheem Kev Siv Rau Txhuas Alloys
Ua tiav qhov siab - Zoo aluminium Welloy yuav tsum tau paub cov hauv qab no:
Npaj Npaj Ntev
• Kev tshem tawm oxide: Lub alumina txheej yuav tsum tau muab tshem tawm ua ntej vuam siv stainless hlau txhuam) lossis tshuaj lom neeg etchants (piv txwv li, nitric acid daws).

Kev Cuam Tshuam Cov Cuam ntawm Txhuas Alloy Vuam
Vuam enables enables ua rau cov fabrication ntawm cov txheej txheem txhuas uas yuav ua tsis tau nrog cov tshuab ua kom yooj yim. Hauv Aerospace, Welded 6061 thiab 2219 aluminium alloys alloys alllots roj tso tsheb hlau luam yeeb thiab airframum Cheebtsam. Hauv kev tsim cov lag luam, gmaw - welded 5000-series alloys alloys txo lub tsheb hnyav, txhim kho roj efficiency. Lub zog txuas ntxiv hluav taws xob cia siab rau Welded Aluminium rau cov vaj huam sib luag solar thiab cua lub zog, siv tus corrosion tsis kam thiab kev txij nkawm tsawg.
Advances zoo li kev sib txhuam ua kom muaj kev sib ntaus sib tua (FSW) tau hloov kho lub zog txhuas, puas muaj qhov tsis muaj zog, tsis muaj zog} dawb welloys (piv txwv li, 7075). Laser Beaj vuam (LBW) muaj precision rau cov khoom siv hluav taws xob, koom nrog cov ntawv nplaum nyias nyias nrog cov lus tawm ua kom sov me me.
Hauv kev xaus, alloys alloys tuaj yeem welded ua tiav nrog txoj kev txawj ntse thiab cov txheej txheem. Thaum cov kev sib tw zoo li cov txheej oxide, kev tswj hwm kub, thiab tswj hwm los ntawm kev xaiv cov khoom sib txawv, thiab tswj cov kev tawm suab sov. Raws li kev lag luam thov sib dua, ntau dua cov ntaub ntawv muaj sia, txhuas alloy walding yuav nyob twj ywm hauv kev tsim kho niaj hnub no hauv txhua lub tsheb kev tshawb nrhiav kev tshawb nrhiav.
