Pre-Weld Workpiece Ntxuav rau Flash Butt Vuam Tshuab

Flash taub qab vuam yog cov txheej txheem siv dav hauv kev lag luam vuam rau koom nrog cov hlau ua haujlwm.Txhawm rau kom muaj zog thiab txhim khu kev qha welds, nws yog ib qho tseem ceeb los npaj cov khoom ua haujlwm kom zoo los ntawm kev ntxuav lawv ua ntej txheej txheem vuam.Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog qhov tseem ceeb ntawm pre-weld workpiece tu rau flash taub qab vuam tshuab.

Flash taub qab vuam, tseem hu ua kev tiv thaiv pob tw vuam, koom nrog ob lub hlau ua haujlwm los ntawm kev tsim cov cua sov los ntawm kev ua haujlwm, ua rau cov khoom siv vuam zoo.Qhov kev vam meej ntawm cov txheej txheem vuam no zoo heev nyob ntawm qhov huv ntawm cov khoom ua haujlwm tau koom nrog.Nov yog qee qhov laj thawj tseem ceeb vim li cas kev ntxuav ua ntej weld workpiece yog qhov tseem ceeb:

1. Kev tshem tawm cov kab mob: Cov khoom ua haujlwm feem ntau muaj cov kab mob xws li xeb, xim, roj, thiab av ntawm lawv qhov chaw.Cov kab mob no tuaj yeem cuam tshuam cov txheej txheem vuam los ntawm kev tiv thaiv kev sib cuag hluav taws xob thiab kev ua kom sov.Kev ntxuav cov khoom ua haujlwm kom ntseeg tau tias cov kab mob no raug tshem tawm, tso cai rau kev sib txuas zoo dua.
2. Txhim kho hluav taws xob Conductivity: Cov workpieces huv si muaj cov khoom siv hluav taws xob zoo dua, uas yog qhov tseem ceeb rau cov txheej txheem vuam pob tw.Thaum cov workpieces nyob rau hauv kev sib cuag, ib tug tam sim no dhau los ntawm lawv, ua kom sov ntawm qhov chaw sib cuag.Cov chaw huv si ua kom muaj txiaj ntsig zoo tam sim no, ua rau muaj kev ua haujlwm zoo dua thiab tswj kev vuam.
3. Tsawg qhov tsis xws luag: Vuam tsis xws luag, xws li voids, cracks, thiab inclusions, feem ntau yuav tshwm sim thaum workpieces tsis zoo huv si.Cov chaw huv si txhawb kev sib koom ua ke sib koom ua ke, txo qhov muaj feem ntawm cov teeb meem no thiab ua kom cov weld qhov kev ncaj ncees.
4. Txhim kho Weld tsos: Cov workpieces huv si ua rau kom huv thiab zoo nkauj dua weld zoo li.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov pom kev zoo ntawm cov vuam yog ib qho kev txhawj xeeb, xws li hauv kev lag luam tsheb lossis aerospace.

Cov txheej txheem ntawm pre-weld workpiece tu feem ntau suav nrog kev siv ntau txoj hauv kev, xws li kev ntxuav abrasive, tshuaj ntxuav, lossis kev tu txhua yam, nyob ntawm seb hom thiab qhov xwm txheej ntawm cov khoom ua haujlwm.Kev xaiv ntawm txoj kev ntxuav yuav tsum tau txiav txim siab txog cov kev cai tshwj xeeb ntawm txoj haujlwm vuam.

Nyob rau hauv xaus, pre-weld workpiece tu yog ib qho tseem ceeb kauj ruam nyob rau hauv lub flash taub qab vuam txheej txheem.Nws ua kom muaj kev tshem tawm cov kab mob, txhim kho hluav taws xob conductivity, txo qhov tsis xws luag, thiab txhim kho tag nrho cov khoom zoo ntawm vuam.Los ntawm kev nqis peev hauv kev ua haujlwm kom zoo, cov welds tuaj yeem ua tiav cov khoom muaj zog, txhim khu kev qha, thiab ua kom zoo nkauj zoo nkauj, ua tau raws li cov qauv kev lag luam siab tshaj plaws.
