Vim Li Cas Laser Welding Machines Xav Tau Roj Thaum Vuam

Lub tshuab laser vuam yog ib hom khoom siv vuam uas siv ntau hauv kev tsim khoom lag luam, thiab nws kuj yog lub tshuab tseem ceeb rau kev ua cov khoom siv laser. Txij li thaum pib tsim lub tshuab laser vuam mus txog rau tam sim no thev naus laus zis tau maj mam loj hlob, ntau hom tshuab vuam tau tsim, suav nrog lub tshuab laser vuam siv tes dav dav, uas yog tus pabcuam muaj zog rau kev ua haujlwm vuam.

Vim li cas ho siv cov roj tiv thaiv thaum vuam nrog lub tshuab vuam laser tes? Lub tshuab vuam laser tes yog ib hom kev vuam tshiab, feem ntau yog rau kev vuam cov khoom siv nyias-phab ntsa thiab cov khoom ua kom raug, uas tuaj yeem ua tiav qhov chaw vuam, vuam taub qab vuam, vuam ceg, sealing vuam, thiab lwm yam, nrog qhov sib piv tob, qhov dav vuam me me, thiab cua sov Thaj chaw cuam tshuam me me, deformation me me, vuam ceev ceev, du thiab zoo nkauj vuam seam, tsis tas yuav daws lossis tsuas yog xav tau kev kho yooj yim tom qab vuam, zoo weld seam, tsis muaj porosity, kev tswj hwm meej, qhov chaw tsom me me, qhov tseeb qhov chaw siab, yooj yim kom paub txog automation.

1. Nws tuaj yeem tiv thaiv lub lens tsom xam los ntawm cov pa phem ntawm cov hlau thiab cov dej ntws tawm ntawm cov kua dej

Cov roj tiv thaiv tuaj yeem tiv thaiv lub lens tsom ntawm lub tshuab laser vuam los ntawm cov pa phem ntawm cov hlau thiab cov dej ntws tawm, tshwj xeeb tshaj yog nyob rau hauv kev vuam fais fab siab, vim tias qhov kev tawm mus ua lub zog heev, thiab nws yog qhov tsim nyog dua los tiv thaiv lub lens lub sijhawm no.

2. Cov roj tiv thaiv zoo rau kev tshem tawm cov plasma shielding los ntawm kev siv laser vuam fais fab loj

Cov pa hlau nqus cov teeb laser thiab ionizes rau hauv cov huab plasma, thiab cov pa tiv thaiv nyob ib puag ncig cov pa hlau kuj ionized vim yog cua sov. Yog tias muaj plasma ntau dhau, cov teeb laser raug plasma noj me ntsis. Plasma muaj nyob rau ntawm qhov chaw ua haujlwm ua lub zog thib ob, uas ua rau qhov nkag mus tob thiab qhov chaw ntawm lub pas dej weld dav dua.

Qhov kev sib sau ua ke ntawm cov electrons yog nce ntxiv los ntawm kev nce qhov kev sib tsoo ntawm peb lub cev ntawm cov electrons nrog cov ions thiab cov atoms nruab nrab kom txo qhov ceev ntawm cov electron hauv plasma. Qhov sib dua cov atoms nruab nrab, qhov siab dua qhov kev sib tsoo zaus thiab qhov siab dua qhov kev sib sau ua ke; ntawm qhov tod tes, tsuas yog cov roj tiv thaiv nrog lub zog ionization siab yuav tsis ua rau qhov ceev ntawm cov electron nce ntxiv vim yog qhov ionization ntawm cov roj nws tus kheej.

 

3. Cov roj tiv thaiv tuaj yeem tiv thaiv cov khoom ua haujlwm los ntawm oxidation thaum lub sijhawm vuam

Lub tshuab laser welding yuav tsum siv ib hom roj rau kev tiv thaiv, thiab qhov kev pab cuam yuav tsum tau teeb tsa rau hauv txoj kev uas cov roj tiv thaiv tau tso tawm ua ntej thiab tom qab ntawd lub laser raug tso tawm, yog li tiv thaiv kev oxidation ntawm lub laser pulsed thaum lub sijhawm ua haujlwm tas mus li. Cov roj inert tuaj yeem tiv thaiv lub pas dej molten. Thaum qee cov ntaub ntawv raug welded tsis hais txog qhov oxidation ntawm qhov chaw, kev tiv thaiv yuav tsis raug txiav txim siab, tab sis rau feem ntau daim ntawv thov, helium, argon, nitrogen thiab lwm yam roj feem ntau siv los ua kev tiv thaiv los tiv thaiv cov khoom ua haujlwm los ntawm kev raug oxidation thaum lub sijhawm vuam.

4. Kev tsim cov qhov nozzle

Cov roj tiv thaiv raug txhaj rau ntawm qee qhov siab los ntawm lub nozzle kom mus txog qhov chaw ntawm cov khoom ua haujlwm. Lub hydrodynamic duab ntawm lub nozzle thiab lub cheeb ntawm qhov hluav taws xob yog qhov tseem ceeb heev. Nws yuav tsum loj txaus los tsav cov roj tiv thaiv txau kom npog qhov chaw vuam, tab sis txhawm rau tiv thaiv lub lens zoo thiab tiv thaiv cov pa hlau los ntawm kev ua qias tuaj lossis cov hlau splashing los ntawm kev ua puas lub lens, qhov loj ntawm lub nozzle kuj yuav tsum raug txwv. Tus nqi ntws kuj yuav tsum tau tswj, txwv tsis pub cov laminar ntws ntawm cov roj tiv thaiv yuav dhau los ua turbulent, thiab huab cua yuav koom nrog hauv lub pas dej molten, thaum kawg tsim cov pores.

Hauv kev vuam laser, cov pa roj tiv thaiv yuav cuam tshuam rau cov duab vuam, qhov zoo ntawm vuam, qhov nkag mus rau hauv vuam thiab qhov dav ntawm qhov nkag mus. Feem ntau, cov pa roj tiv thaiv yuav muaj qhov zoo rau vuam, tab sis nws kuj tseem yuav ua rau muaj qhov tsis zoo.

 

Lub Luag Haujlwm Zoo:

1) Kev siv cov pa roj shielding kom raug yuav tiv thaiv tau lub pas dej weld kom txo lossis tiv thaiv kev oxidation;

2) Qhov cua tshuab kom raug ntawm cov roj tiv thaiv tuaj yeem txo qhov spatter tsim thaum lub sijhawm vuam;

3) Kev tshuab kom raug ntawm cov roj tiv thaiv tuaj yeem txhawb nqa kev sib kis ntawm lub pas dej vuam thaum nws khov, ua rau cov duab vuam zoo ib yam thiab zoo nkauj;

4) Kev siv cov pa roj tiv thaiv kom raug tuaj yeem txo qhov cuam tshuam ntawm cov hlau vapor plume lossis plasma huab ntawm laser, thiab ua rau kom siv tau zoo ntawm laser;

5) Kev tshuab cov pa roj shielding kom raug tuaj yeem txo qhov weld porosity.

Tsuav yog hom roj, tus nqi ntws roj, thiab hom tshuab cua xaiv raug, ces yuav tau txais qhov zoo tagnrho. Txawm li cas los xij, kev siv roj tiv thaiv tsis raug kuj tseem yuav ua rau muaj kev cuam tshuam tsis zoo rau kev vuam.

Cov Teeb Meem Tsis Zoo:

1) Kev tso pa roj tsis raug yuav ua rau cov vuam tsis zoo:

2) Xaiv hom roj tsis raug yuav ua rau muaj kab nrib pleb hauv qhov vuam, thiab kuj tseem yuav ua rau cov khoom siv kho tshuab ntawm qhov vuam txo qis;

3) Kev xaiv qhov nrawm ntawm cov pa roj tsis raug yuav ua rau muaj kev oxidation ntau dua ntawm qhov vuam (txawm tias qhov nrawm ntawm cov pa roj loj dhau lossis me dhau), thiab kuj tseem yuav ua rau cov hlau vuam raug cuam tshuam los ntawm cov zog sab nraud, ua rau qhov vuam tawg lossis tsis sib xws;

4) Xaiv txoj kev txhaj roj tsis raug yuav ua rau lub vuam tsis ua tiav qhov kev tiv thaiv lossis txawm tias tsis muaj kev tiv thaiv lossis muaj kev cuam tshuam tsis zoo rau kev tsim vuam;

5) Kev ua pa ntawm cov roj tiv thaiv yuav muaj qee qhov cuam tshuam rau qhov nkag mus ntawm weld, tshwj xeeb tshaj yog thaum vuam cov phaj nyias, nws yuav txo qhov nkag mus ntawm weld.

 

Feem ntau, helium yog siv ua cov roj tiv thaiv, uas tuaj yeem tswj cov plasma kom zoo tshaj plaws, yog li ua rau qhov tob nkag mus thiab ua rau qhov vuam ceev dua; thiab nws yog lub teeb hauv qhov hnyav thiab tuaj yeem khiav tawm, thiab nws tsis yooj yim ua rau muaj qhov hws. Tau kawg, los ntawm peb qhov kev cuam tshuam vuam tiag tiag, qhov cuam tshuam ntawm kev siv argon tiv thaiv tsis yog qhov phem.
