Yuav Ua Li Cas Tiv Thaiv Distortion Thiab Hlawv-Ntawm Thaum Vuam Cov Ntawv Txhuas Txhuas

Nyias aluminium ntawv yog dav siv nyob rau hauv hluav taws xob enclosures, automotive Cheebtsam, tshiab zog khoom, khoom siv hluav taws xob, thiab precision sheet hlau fabrication. Txawm li cas los xij, welding nyias aluminium feem ntau nthuav tawm ob qhov teeb meem loj: distortion thiab hlawv-los ntawm.

Tom qab vuam, workpieces yuav ua warped, dented, los yog dimensionally tsis raug. Hauv qhov xwm txheej hnyav dua, cov cua sov ntau dhau tuaj yeem ua rau cov khoom tawg los ntawm, tawm hauv qhov los yog cov npoo tawg.

Cov teeb meem no cuam tshuam rau cov khoom zoo li, cov qauv zoo, kev tsim khoom, thiab cov nqi tsim khoom.

Vim li cas cov ntawv txhuas nyias nyias thiaj li ua rau distortion thiab hlawv-los ntawm? Cov neeg tsim khoom tuaj yeem txhim kho cov txiaj ntsig vuam li cas? Thiab cov khoom siv vuam twg tsim nyog rau kev siv nyias nyias?

Kev daws cov teeb meem no yuav tsum tau ntau dua li tsuas yog txo cov vuam fais fab. Cov khoom siv, daim ntawv thickness, kev sib koom tsim, vuam tsis, qhov chaw ua haujlwm, thiab cov cuab yeej cuab tam yuav tsum raug txiav txim siab.

1. Vim li cas cov ntawv nyias nyias nyias tuaj yeem cuam tshuam thiab hlawv-dhau?

Aluminium muaj cov thermal conductivity siab, qhov qis melting point, thiab tseem ceeb thermal expansion. Cov nplooj nyias nyias kuj muaj qhov txwv nruj thiab tsis tshua muaj cua sov, ua rau lawv tshwj xeeb rau cov cua sov nkag thaum vuam.

1.1 High Thermal Conductivity Ua rau kub ceev Dissipation

Aluminium ua kom muaj cua sov zoo, tso cai rau vuam cua sov kom kis tau sai ntawm qhov sib koom ua ke rau hauv cov khoom nyob ib puag ncig.

Yog hais tias cov cua sov input tsis txaus, qhov sib koom ua ke yuav tsis ua kom zoo fusion. Txawm li cas los xij, ua kom cov cua kub nkag ntau dhau tuaj yeem ua rau muaj kev kub ntxhov hauv cheeb tsam.

Vim tias cov ntawv txhuas nyias nyias muaj qhov txwv thermal, kev hloov pauv kub tuaj yeem cuam tshuam sai sai rau lawv cov duab, ua rau muaj kev sib hloov lossis kev sib hloov.

1.2 Aluminium qhov qis Melting Point ua rau muaj kev pheej hmoo ntawm kev kub hnyiab

Aluminium melts ntawm kwv yees li 660 ° C, thaum nws nto oxide muaj ntau dua melting point.

Thaum vuam cua sov ua kom muaj zog hauv thaj chaw me me, cov khoom siv hauv paus tuaj yeem yaj sai. Yog tias vuam fais fab, kev ceev ceev, lossis lwm yam txheej txheem tsis zoo sib xws, cov hlau molten yuav vau, ua rau muaj kev nkag mus ntau dhau, hlawv-los ntawm qhov.

Cov npoo nyias nyias, qhov sib txawv ntawm cov khoom ua haujlwm, thiab cov chaw raug cov cua sov rov qab yog qhov tshwj xeeb.

1.3 Thermal Expansion and Contraction Ua Distortion

Thaum lub sij hawm vuam, cov khoom nthuav tawm thaum nws sov thiab cog lus thaum nws txias.

Yog hais tias cov cua sov yog concentrated ntawm ib sab ntawm lub workpiece los yog cov vuam ib ntus yog tsim tsis zoo, shrinkage tsis sib xws tuaj yeem tsim kev ntxhov siab.

Rau cov ntawv nyias nyias, txawm tias me me ntawm qhov tsis sib xws tuaj yeem ua rau pom kev tsis sib haum, kev deformation hauv zos, lossis teeb meem flatness.

1.4 Nto Oxide thiab paug cuam tshuam rau vuam ruaj khov

Aluminium ib txwm tsim txheej txheej oxide thaum raug huab cua. Roj, noo noo, plua plav, thiab lwm yam khoom paug tuaj yeem cuam tshuam rau vuam zoo.

Ib qho kev tsis sib haum xeeb ntawm qhov chaw yuav ua rau tsis muaj kev sib cuag lossis tus cwj pwm molten-pool, uas tuaj yeem ua rau tsis tiav fusion, porosity, thiab tsis zoo weld zoo.

Kev tu kom zoo thiab kev npaj yog li qhov tseem ceeb ntawm nyias aluminium vuam.

2. Yuav ua li cas los tiv thaiv Distortion thiab hlawv-Nyob rau hauv thaum Vuam nyias Aluminium

Txhawm rau txhim kho vuam zoo, cov tuam txhab tsim khoom yuav tsum tswj cov khoom siv hluav taws xob, ua kom zoo dua cov txheej txheem, txhim kho qhov chaw ua haujlwm, thiab xaiv qhov tsim nyog vuam ib ntus.

2.1 Tswj cov cua kub nkag los tiv thaiv ib cheeb tsam overheating

Thaum tshav kub kub input yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau nyias aluminium vuam zoo.

Cov cua kub ntau dhau tuaj yeem ua rau nkag mus tob, ntug tawg, thiab hlawv-dhau. Tsis txaus cua sov, ntawm qhov tod tes, yuav ua rau tsis tiav fusion thiab tsis muaj zog sib koom ua ke.

Cov kev ntsuas pom zoo suav nrog:

• Xaiv lub zog vuam tsim nyog lossis tam sim no raws li cov khoom tuab.

• Match vuam lub sij hawm nrog kev mus los ceev thiab cov txheej txheem yuav tsum tau.
