Nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws lub zog hluav taws xob, qhov yuav tsum tau ua rau tooj liab-aluminium pob qij txha tau dhau los ua ntau thiab siv ntau dua thiab cov kev xav tau nce siab dua. Feem ntau cov txheej txheem tooj liab-aluminium welding nyob rau hauv kev ua lag luam niaj hnub no muaj xws li: flash butt welding, dov kev sib txhuam vuam thiab brazing. Cov editor hauv qab no yuav qhia cov yam ntxwv ntawm cov txheej txheem no rau koj.
Kev sib txhuam dov welding tam sim no tsuas yog txwv rau vuam tuav, thiab welded tuav kuj tuaj yeem ua rau hauv daim hlau, tab sis nws yog ib qho yooj yim ua rau tawg ntawm interlayers thiab welds.
Brazing yog siv dav, thiab nws feem ntau yog siv rau thaj tsam loj thiab tsis xwm yeem tooj liab-aluminium pob tw pob qij txha, tab sis muaj cov yam ntxwv xws li kev ceev ceev, tsis tshua muaj kev ua haujlwm, thiab tsis ruaj khov.
Flash taub qab vuam tam sim no yog txoj hauv kev zoo tshaj plaws rau vuam tooj liab thiab txhuas. Flash taub qab vuam muaj qhov xav tau siab ntawm daim phiaj hluav taws xob, thiab tseem muaj qhov kub hnyiab. Txawm li cas los xij, welded workpiece tsis muaj pores thiab dross nyob rau hauv weld seam thiab lub zog ntawm weld seam yog siab heev. Nws tuaj yeem pom tias nws qhov tsis zoo yog qhov pom tseeb, tab sis nws qhov zoo tau cuam tshuam nws qhov tsis zoo.
Cov tooj liab-aluminium flash vuam pob tw vuam txheej txheem yog complex, thiab parameter qhov tseem ceeb muaj ntau yam thiab intricately txwv ib leeg, txhua yam uas yuav cuam tshuam rau nws vuam zoo. Tam sim no, tsis muaj txoj hauv kev tshawb pom zoo rau qhov zoo ntawm tooj liab-aluminium vuam, thiab feem ntau ntawm lawv siv kev puas tsuaj los xyuas kom nws lub zog (txog lub zog ntawm cov khoom siv txhuas), kom nws tuaj yeem ua haujlwm tau zoo hauv daim phiaj hluav taws xob.
Kev xav tau rau cov khoom siv vuam ntawm tooj liab-aluminium taub qab vuam tshuab
1. Cov khoom yuav tsum muaj ntawm lub taub qab vuam tshuab;
Qib ntawm vuam consumables yuav tsum tsis txhob qis dua tus qauv
2. Hloov mus rau flash pob tw welding tshuab cov ntaub ntawv saum npoo yuav tsum:
Yuav tsum tsis txhob muaj roj stains thiab lwm yam khoom uas cuam tshuam rau conductivity thaum welding ntawm qhov chaw, thiab yuav tsum tsis txhob muaj xim ntawm vuam kawg nto thiab ob sab.
3. Hloov mus rau lub taub qab vuam tshuab cov khoom siv ua ntej kev npaj:
Thaum lub zog ntawm cov khoom yog siab dhau lawm, nws yuav tsum tau annealed ua ntej kom ntseeg tau tias tsis tshua muaj hardness thiab siab plasticity ntawm weldment, uas yog conducive rau extrusion ntawm kua hlau slag thaum upsetting.
4. Hloov mus rau cov khoom loj ntawm lub taub qab vuam tshuab;
Thaum xaiv qhov tuab ntawm vuam workpiece raws li qhov loj me me ntawm lub vuam tshuab, xaiv tus nqi tsis zoo rau tooj liab thiab tus nqi zoo rau txhuas (feem ntau 0.3 ~ 0.4). Lub thickness sib txawv ntawm tooj liab thiab txhuas yuav tsum tsis txhob tshaj tus nqi no, txwv tsis pub nws yuav ua rau tsis txaus los yog oversetting txaus, uas yuav cuam tshuam rau lub vuam zoo.
5. Yuav tsum muaj rau cov khoom seem ntawm lub taub qab vuam tshuab:
Lub ntsej muag kawg ntawm lub vuam yuav tsum tiaj tus, thiab qhov kev txiav tawm yuav tsum tsis txhob loj dhau, uas yuav ua rau cov cua sov tsis sib xws ntawm ob qhov kawg ntawm qhov vuam thiab ua rau cov vuam tsis sib xws.
6. Flash taub qab vuam tshuab workpiece blanking loj:
Thaum blanking lub weldment, tus nqi ntawm flash burning thiab chim siab yuav tsum tau ntxiv rau daim duab raws li cov txheej txheem vuam.
