Cov khoom siv twg yog qhov zoo rau vuam aluminium alloys? Puas yog oxidation nquag tshwm sim?

Aluminium alloy yog lub teeb ci ntsa iab thiab muaj zog, ua rau nws dav siv hauv kev lag luam, cov khoom siv hauv tsev, thiab ntu aviation. Txawm li cas los xij, ntau tus neeg tawm tsam thaum vuam aluminium alloy: cov cuab yeej twg yuav tsum xaiv, thiab yuav ua li cas lawv tuaj yeem zam kev oxidation teeb meem? Niaj hnub no, kuv yuav piav nws ncaj qha rau kev pab koj xaiv cov cuab yeej txoj cai thiab zam cov teeb meem oxidation hauv txhuas alloy vuam.

 I. Xaiv cov khoom zoo rau txhuas alloy vuam

Muaj ntau cov khoom siv cov cuab yeej siv vuam rau txhuas alloy. Raws li cov chaw tsim khoom ntawm cov chaw welders, laser vuam tshuab, thiab cov nyom laser laser vuam tshuab, peb to taub qhov ua tau zoo ntawm txhua hom. Koj tuaj yeem xaiv raws li koj cov khoom ntim ntau thiab cov kev xav tau:

1. Khoom Welder: Qhov kev xaiv zoo tshaj plaws rau nyias phab ntsa alsoy batch vuam

  - Aluminium Alloy Whot Welders siv cov elecodes siv cov hluav taws xob thiab tsim kom muaj cua sov los ntawm kev sib chwv thiab ua rau weld point. Qhov zoo dua yog nrawm; Txhua Weld Taw Qhia siv tsuas yog 0.1-1 thib ob. Qhov no zoo tagnrho rau nyias-phab ntsa alloy alloy (0.1-3 hli) hauv pob qij txha vuam, xws li txhuas ntxas cov khoom siv hauv tsev thiab cov khoom me me txhuas.

  - Txawm li cas los xij, txhuas alloy yog kev coj ua thiab dissipates kub sai sai. Koj xav tau cov chaw pov thawj tshwj xeeb nrog cov vuam siab tam sim no thiab luv luv vuam kom tsis txhob ua tiav vuam vuam. Cov hluav taws xob tuaj yeem oxidize thiab hnav vim yog kub, yog li kev sib tsoo los sis sib tsoo tas li yog tsim nyog los tswj kev siv vuam ruaj khov.

2. Laser Vuam Tshuab: Qhov tseem ceeb rau High-precision Txhuas Alloy Vuam

  - Laser vuam tshuab Siv Lub Zog Loj Laser Laser Laser Laser Laser Larle Alloy. Thaj chaw cua sov-cuam tshuam yog qhov me me heev, cia kev tswj hwm ntawm Weld Seam. Lub resulting Weld leeg yog tus thiab yuav tsum tau tsawg lossis tsis muaj kev kho tom qab weld. Nws tuaj yeem Weld Aluminoy Alloy los ntawm 0.05-8 mm tuab thiab haum rau high-tseem ceeb thov, xws li txhuas alloy thav duab thiab cov ntsuas ntsuas ntsuas qhov chaw.

  - Thaum vuam aluminium alloy, xaiv ib liaser vuam tshuab nrog mem tes ua haujlwm kom txo cov tswv yim tshav kub thiab tiv thaiv deformation. Tsis tas li, siv cov roj txheem sib cav kom tiv thaiv oxidation thaum lub sij hawm vuam, kom meej weld lub zog thiab tsos.

3. Rober Laser Laser Tshuab: Qhov kev xaiv uas nyiam tshaj plaws rau cov qauv loj

  - Vuam laser vuam vuam vuam tshuab sib txuas ua ke nrog kev siv npab ua ke kom ua tiav kev siv hluav taws xob, muaj peev xwm ua haujlwm tau ntev 24 teev. Vuam qhov tseeb yog ruaj khov thiab tsis cuam tshuam los ntawm tib neeg kev ua haujlwm sib txawv, xws li batch ntau lawm cov cuab yeej loj thiab chassis Cheebtsam hauv kev lag luam automotive.

  - Nws tuaj yeem coj ntau yam ntawm txhuas alloy thicknesses thiab complex vuam vrajectories, ua kom zoo tshaj rau cov tuam txhab uas nrhiav ntsuas thiab txo cov nqi ua haujlwm.

4. Cov khoom siv ib txwm: Lub rooj sib tham cov kev siv vuam

  - Tig welder: siv lub tungsten electrode los tsim ARC, nrog Argon roj tiv thaiv Molten pas dej. Nws yuav tsum tau nyeem cov hlau. Nws muab cov ntsuas kub kho kom sov thiab kev ua kom zoo nkauj ntxiv, haum rau nyias-phab ntsa alloy alloy (0.5-5 mm) hauv txhuas cov hniav nyiaj hniav kub thiab qhov chaw me me. Txawm li cas los xij, nws tau muaj kev ua tau zoo nkauj tsawg thiab yog qhov zoo tshaj rau kev tsim me-batch.

  - Mig Welder: Ntaw Tsis Siv Neeg Hlau Pub Noj, Nrog Vuam Ceev Pib 3-5 zaus sai dua li Tig Vuam. Nws yog qhov haum rau nruab nrab-tuab alloy alloy (3-20 mm) hauv batch vuam, xws li txhuas cov kav dej thiab cov khoom siv. Txawm li cas los xij, nws yuav tsum muaj siab dawb huv (99.99% +) Cov pa roj Argon los tiv thaiv Porosity.

 

Ii. Oxidation teeb meem hauv txhuas alloy vuam thiab yuav ua li cas kom zam lawv

Coob tus neeg txhawj txog oxidation thaum vuam aluminium alloy. Qhov no yog vim qhov xwm txheej ntawm txhuas alloy, tab sis nrog kev nkag siab zoo thiab kev tiv thaiv, nws tuaj yeem zam tau cov txiaj ntsig zoo:

1. Lub hauv paus ua rau oxidation

  - Cov saum npoo ntawm txhuas alloy tau yooj yim nrog cua los ua ib txheej oxide (feem ntau yog alloy tus kheej melting point (nyob ib ncig ntawm 660 ° C). Yog tias cov roj oxide no tsis meej kom muab tshem tawm ntawm cov pas dej Molten, ua rau cov nplais uas tsis sib haum thiab khav theeb hauv Weld Seam. Nws kuj tseem tsis tseem ceeb ntawm cov alloy, cuam tshuam rau Weld lub zog. Ntxiv mus, thaum vuam, yog tias lub pas dej Molten tsis muaj kev tiv thaiv kom raug, oxygen nyob hauv huab cua yuav txuas ntxiv nrog nws, exacerbating oxidation.

2. Kev ntsuas qhov tseem ceeb kom tiv thaiv oxidation

  - Ua kom huv si oxide txheej ua ntej vuam muag: mechanically txhuam cov hlau sib dhos lossis tsau rau hauv ib qho tshwj xeeb txhuas kom yaj cov oxide txheej. Tom qab tu, ua kom tiav cov vuam hauv 4 teev los tiv thaiv cov oxidation theem nrab.
