Tag nrho cov khoom siv laser zoo li laser npav tshuab, laser vuam tshuab, laser txiav tshuab, thiab lwm yam muaj ib yam ua ke, uas yog kev ua haujlwm siab thiab raug. Vim tias qhov no, nws hloov ntau cov khoom siv ua ua qub. Txawm li cas los xij, yog tias cov khoom siv fiber ntau laser vuam tau nruab rau hauv ib qho chaw ua haujlwm uas muaj qhov xwm txheej hnyav thiab cov kev txwv ntawm cov cuab yeej siv tau zoo yuav ua rau lub tshuab ua haujlwm laser tsis ua haujlwm tsis zoo, qhov ua tau zoo tshaj plaws tsis tuaj yeem ua tiav. Yuav ua li cas hais txog cov ntsiab lus tseem ceeb uas tsis quav ntsej thaum siv cov tshuab laser ua lub vuam tshuab?
Nyob rau hauv dav dav, cov ntsiab lus uas yooj yim pom rau hauv kev siv cov tshuab ua lub ntsej muag laser vuam siv tau muab faib ua sab nraud thiab sab hauv:
Thawj yog qhov ua rau sab nraud: lub handheld laser vuam tshuab muaj qhov ntsuas siab. Yog tias qhov tseeb ntawm lub workpiece yuav tsum tau welded yog qhov siab dhau, yuav tsum muaj qhov tsis txaus ntseeg ntawm txoj kev vuam; qhov tsis huv ntawm lub workpiece saum npoo thiab qhov tsis sib thooj ntawm cov khoom siv workpiece yuav cuam tshuam ncaj qha rau ntawm lub qhov txuas. Lub sib xws ntawm workpiece; thiab cov khoom siv kho uas kho tau cov haujlwm ua haujlwm, uas tuaj yeem kho qhov chaw thiab tuaj yeem ruaj khov ntawm lub vuam workpiece, uas yooj yim rau kev sib dhos thiab cov hlau ntawm lub vuam workpiece. Yog hais tias qhov zoo ntawm cov xov tooj ntawm tes lub laser vuam tshuab lub tshuab ua kom tsis txaus, thiab qhov tseeb qhov yuam kev yog qhov loj heev, nws yuav cuam tshuam ntau heev rau qhov chaw vuam raug.
Ua raws li kev ua haujlwm sab hauv: laser welding txheej txheem tsis. Cov kev txiav txim suav nrog: laser lub zog, laser waveform thiab vuam ceev chaw, teeb focal ntev, thiab lwm yam. Lub zog thiab ceev cov cuam tshuam tau ntxim nyiam tshaj. Feem ntau hais lus, lub zog laser txiav txim siab qhov tuab ntawm vuam, thiab vuam nrawm cuam tshuam rau kev nkag mus ntawm vuam nto; tom qab ntawd qhov zoo ntawm qhov kho qhov muag. Raws li qhov kev ua ntawm lub tshuab fais fab siab, qhov ua tau zoo ntawm cov khoom kho qhov muag no yuav tsis zoo, lub transmittance yuav raug txo kom tsawg, thiab lub thermal lens cuam tshuam yuav tshwm sim. Yog tias muaj txheej txheem saum npoo, nws yuav ua rau kom qhov kis poob thiab cuam tshuam rau qhov tsis zoo vuam.
