Common Laser Welding Parameter yuam kev: Tshiab Rau Laser Vuam? Zam kev teeb tsa yuam kev no

Rau cov pib tshiab, kev khiav hauj lwm lub tshuab laser vuam feem ntau yog ncaj nraim. Txawm li cas los xij, kev ua tiav cov welds zoo nyob ntawm kev xaiv qhov tseeb vuam tsis zoo. Kev teeb tsa tsis raug tuaj yeem ua rau muaj teeb meem xws li kev nkag mus tsis tiav, hlawv-dhau, porosity, ntau dhau spatter, thiab workpiece deformation, tag nrho cov no nce nqi ntau lawm thiab rov ua haujlwm dua.

Ntau tus neeg ua haujlwm ntseeg tias kev ua kom lub zog laser yuav cia li tsim cov welds zoo dua. Nyob rau hauv kev muaj tiag, laser vuam kev ua tau zoo nyob ntawm seb qhov kev sib npaug ntawm lub zog laser, vuam ceev, focal txoj hauj lwm, shielding roj, thiab cov khoom siv welded.

Qhov yuam kev 1: Siv lub zog laser siab tshaj plaws

Ib qho yuam kev feem ntau yog teeb tsa lub zog laser siab dhau los ua kom muaj zog vuam.

Lub hwj chim ntau dhau tuaj yeem ua rau kub hnyiab tau yooj yim, qhov dav ntawm weld seams, spatter ntau dua, thiab qhov loj dua qhov cuam tshuam los ntawm tshav kub, uas tuaj yeem txo qhov pom thiab qhov tseeb ntawm cov khoom tiav.

Hloov chaw, xaiv lub zog laser raws li cov khoom siv thiab tuab. Cov ntawv hlau nyias feem ntau xav tau lub zog qis, thaum cov ntaub ntawv tuab xav tau lub zog siab dua ua ke nrog qhov tsim nyog vuam ceev.

Qhov yuam kev 2: Ua kom qhov vuam ceev tsis tu ncua

Lub zog laser thiab vuam ceev yuav tsum ua haujlwm ua ke ib txwm.

Yog tias qhov vuam ceev nrawm dhau, lub zog laser tsis nyob ntawm cov khoom siv ntev txaus, ua rau muaj kev nkag mus tsis txaus lossis tsis txuas ntxiv welds. Yog tias qhov nrawm nrawm dhau, cov cua kub ntau dhau tuaj yeem ua rau kub hnyiab, cuam tshuam, lossis oxidation.

Tsis yog kho ib qho kev ntsuas xwb, ua kom zoo zog thiab nrawm ua ke kom ua tiav qhov zoo tshaj plaws vuam cov txiaj ntsig.

Qhov yuam kev 3: Tsis quav ntsej qhov Focal Position

Lub focal txoj hauj lwm ncaj qha cuam tshuam rau laser zog ceev thiab feem ntau overlooked los ntawm inexperienced tswv.

Yog tias qhov tsom xam siab dhau lawm, lub zog laser yuav tsis tshua muaj siab, ua rau muaj kev nkag mus rau hauv ntiav. Yog tias qhov tsom xam qis dhau lawm, cov cua kub ntau dhau yuav ua rau kub hnyiab los yog tsis ruaj tsis khov weld tsim.

Qhov zoo tshaj plaws focal txoj hauj lwm txawv nyob ntawm seb cov khoom thiab thickness. Kev sim welds ua ntej ntau lawm yog txoj hauv kev zoo tshaj plaws los kho qhov teeb tsa no.

Qhov yuam kev 4: Tsis raug Shielding Gas Chaw

Shielding gas plays lub luag haujlwm tseem ceeb hauv laser vuam los ntawm kev txo oxidation thiab txhim kho vuam zoo.

Yog tias cov roj ntws tsawg dhau, oxidation thiab discoloration yuav tshwm sim. Yog tias cov dej ntws siab dhau lawm, nws tuaj yeem cuam tshuam lub pas dej molten thiab nce spatter.

Cov ntaub ntawv sib txawv yuav xav tau cov roj sib txawv, xws li nitrogen lossis argon. Xaiv qhov tsim nyog cov pa roj thiab ntws tus nqi pab txhim kho weld zoo ib yam thiab nto zoo.

Qhov yuam kev 5: Siv tib qhov tsis sib xws rau txhua yam khoom siv

Cov hlau sib txawv yuav tsum muaj qhov sib txawv ntawm qhov sib txawv.

Piv txwv li:

• Stainless hlau yog ib qho yooj yim rau welding thiab muab cov txheej txheem dav dua.

• Cov pa roj carbon steel yuav tsum muaj qhov sib npaug zoo ntawm kev nkag mus thiab qhov zoo li vuam.

• Aluminium alloys muaj siab thermal conductivity thiab reflectivity, yuav tsum tau hloov ntau yam parameter.

• Tooj liab muaj lub siab laser reflectivity thiab thermal conductivity, xav tau ntau zog tswv yim thiab ruaj khov txheej txheem tswj.

Kev siv cov khoom tsis sib xws rau cov khoom sib txawv feem ntau ua rau cov vuam tsis zoo.

yuam kev 6: Pib tsim ntau yam tsis muaj kev sim

Qee lub tuam txhab pib tsim khoom tam sim ntawd tom qab kev txhim kho lub tshuab laser welding tshiab yam tsis muaj kev sim welds.

Txawm hais tias siv cov khoom siv tib yam, qhov sib txawv ntawm cov khoom siv, cov khoom tuab, thiab cov qauv tsim tuaj yeem cuam tshuam rau qhov zoo tshaj plaws vuam tsis.

Ua ntej pawg ntau lawm, ua qhov kev sim welds thiab optimize laser zog, vuam ceev, oscillation dav, focal txoj hauj lwm, thiab shielding roj ntws. Kev ruaj ntseg tsis zoo pab txo qhov tsis xws luag, txhim kho qhov sib xws, thiab txo cov khoom pov tseg kom tsawg.

Yuav Ua Li Cas Nrhiav Txoj Cai Laser Welding Parameters

Beginners tuaj yeem ua kom zoo dua qhov ntsuas vuam los ntawm kev ua raws li cov kauj ruam yooj yim no:

• Xaiv lub zog laser raws li cov khoom siv thiab thickness.

• Kho vuam ceev kom ua tiav qhov xav tau nkag mus thiab weld tsos.

• Fine-tune txoj hauj lwm focal kom zoo zog concentration.

• Teem kom tsim nyog shielding gas hom thiab txaus tus nqi.

• Ua qhov kev sim welds thiab txuag qhov optimized tsis rau yav tom ntej ntau lawm.

Tsim cov ntaub ntawv parameter rau cov khoom sib txawv thiab cov ntaub ntawv tuaj yeem txhim kho kev tsim khoom thiab kev sib txuas ntawm vuam sib xws.

Xaus

Kev vam meej laser vuam tsis yog hais txog kev siv qhov chaw siab tshaj plaws. Nws yog hais txog kev xaiv txoj cai ua ke ntawm laser fais fab, vuam ceev, focal txoj hauj lwm, shielding gas, thiab lwm yam txheej txheem tsis raws li cov khoom thiab daim ntawv thov.

Nrog rau kev ua kom zoo dua qub thiab kev sim, cov tuam ntxhab tuaj yeem ua tiav qhov zoo ntawm cov vuam zoo, txo qis kev ua haujlwm, txhim kho cov khoom tsim tau, thiab txo cov nqi tsim khoom.

Raws li cov kws tshaj lij laser vuam tshuab chaw tsim khoom, PDKJ muab cov khoom siv laser vuam txhim khu kev qha nrog rau kev txhawb nqa thiab cov lus pom zoo raws li cov ntaub ntawv sib txawv thiab kev siv. Txawm hais tias koj tab tom txhim kho koj cov kab ntau lawm lossis tab tom nrhiav kev siv vuam zoo dua, PDKJ tuaj yeem pab koj txhim kho vuam zoo thiab kev ua haujlwm zoo.
