Laser welding tshuab yog cov khoom siv vuam siv heev. Nws tsuas yog siv high-energy laser pulse kom sov cov khoom siv. Lub zog hluav taws xob tawg los ntawm laser kis mus rau sab hauv ntawm cov ntaub ntawv raw mus raws cua sov hloov. Tom qab cov ntaub ntawv raw yaj, cov yam ntxwv ntawm pas dej ua ke yog tsim kom ua tiav txoj ntsiab cai ntawm hlau.
Laser vuam tshuab tau txais txiaj ntsig los ntawm qhov zoo ntawm kev siv vuam vuam ceev, siab qhov siab, ua haujlwm siab, du thiab zoo nkauj txuas, thiab dhau los ua cov cuab yeej tshiab hauv kev lag luam vuam kev lag luam. Laser vuam tshuab yog siv dav tam sim no, tab sis ntau tus neeg ua ntsuas' t paub tias yam khoom siv twg tuaj yeem txuas los ntawm lub tshuab laser welding. Nov yog cov lus qhia ntxaws ntxaws rau koj.
Rau laser vuam ntawm tsawg lub zog thiab siab zog alloy steel, tsuas yog thaum vuam kev tsim nyog, kev sib koom ua ke nrog tib cov khoom zoo xws li lub hauv paus hlau tuaj yeem tau txais.
Laser welding tshuab siv los weld carbon hlau nrog zoo ua tau zoo. Qhov zoo ntawm vuam yog nyob ntawm cov ntsiab lus ntawm impurities. Txhawm rau kom tau txais cov vuam zoo ua ntej, kev muab tso tawm yog qhov tsim nyog thaum cov pa roj carbon siab tshaj li 0. 25%. Nrog rau qhov nce ntawm carbon cov ntsiab lus, lub weld tawg thiab nqis siab tshaj yuav tsum nce ntxiv. Cov pa roj carbon nruab nrab thiab siab thiab cov hlau tsis xeb hlau tuaj yeem ua tiav cov hlau zoo, tab sis kev kho ua ntej thiab tom qab kev kho vuam yuav tsum pom tseeb kom tshem tawm kev ntxhov siab thiab tiv thaiv kom tsis txhob tawg.
Aluminium thiab aluminium alloy yog siab cuam tshuam cov khoom siv raw. Thaum aluminium thiab alloy yog welded, qhov kub tau nce nrog nws. Lub solubility ntawm hydrogen nyob rau hauv txhuas dheev nce. Tus siab hydrogen dhau los ua tus xa cov khoom ntawm weld. Muaj ntau lub qhov hws hauv lub weld. Thaum sib sib zog nqus nqus vuam, tej zaum yuav muaj kab noj hniav ntawm lub hauv paus thiab lub weld hlaws yog me ntsis tsim tsis zoo. Lub vuam ntawm aluminium thiab aluminium alloy muaj qhov yuav tsum muaj ntau dua rau cov khoom siv laser.
Nyob rau hauv dav dav, lub vuam ntawm stainless hlau yog ntau yooj yim kom tau txais lub pob qij txha zoo dua li ntawm cov pa vuam. Vim tias lub vuam kev kub ceev thiab kub cuam tshuam cheeb tsam ntawm laser vuam tsis loj, qhov tshwm sim ntawm kub dhau heev thiab qhov cuam tshuam tsis zoo ntawm kev sib tshooj loj ntawm cov kab sib txuas hauv stainless hlau vuam raug daws, thiab lub weld tsis muaj qhov tsis xws li porosity thiab impurity. Los ntawm kev siv lub zog tsis muaj zog laser los weld nyias daim hlau, cov pob qij txha nrog cov tsos zoo thiab du thiab zoo nkauj welds tuaj yeem tau txais.
Yas yooj yim ib qho thermoplastic thiab thermoplastic elastomer tuaj yeem txais laser vuam tshuab. Txawm li cas los xij, qee qhov ntawm lwm yam kev tsim kho tshuab, xws li PPS thiab kua siv lead ua kua polymer, tsis tuaj yeem siv cov khoom siv laser vuam siv vim yog lawv lub teeb hloov laser. Cov pa roj carbon dub feem ntau ntxiv rau hauv qab raw cov khoom, kom cov khoom siv raw tuaj yeem nqus lub zog txaus thiab ua tau raws li cov cai ntawm laser kis tau tus hlau txuas.
Tooj liab thiab tooj liab tooj hlau vuam tooj liab thiab tooj liab yog feem ntau rau cov teeb meem ntawm qhov tsis tiav fusion thiab nkag mus tsis tiav, yog li cov tshav kub nrog lub zog cov hluav taws xob thiab lub zog siab yuav tsum tau xaiv thiab ntsuas qhov ntsuas yuav tsum coj los sib; thaum lub thickness ntawm workpiece yog nyias los yog cov qauv kev txhav yog me me, thiab tsis muaj kev tiv thaiv kom tsis txhob deformation, nws yooj yim heev kom muaj deformation loj tom qab vuam, thiab thaum sib koom tes welded yog qhov zoo rau kev txwv qhov nruj, nws yooj yim rau muaj vuam kev nyuaj siab; Thaum welding tooj liab thiab tooj liab alloy, nws yog qhov yooj yim kom muaj cov kab nrib pleev kub; porosity yog qhov muaj teeb meem feem ntau hauv cov vuam tooj liab thiab tooj liab tooj hlau.
