Raws li cov txheeb cais muaj feem xyuam, nyob hauv cov teb chaws vam meej tsim, 50% rau 70% ntawm laser ua yog pib ntu. Feem ntau laser vuam thiab laser txiav, laser vuam tshuab tau dhau los ua cov txheej txheem nyob hauv kev lag luam tsheb. Kev vuam ntawm lub cev vaj huam sib luag tuaj yeem txuas cov hlau ua haujlwm ntawm cov thicknesses sib txawv thiab txheej nrog ntau qhov chaw sib xyaw ua ke, thiab tom qab ntawd ntaus cim, kom cov txiaj ntsig vaj huam sib luag tuaj yeem ua tiav cov hlau tsim nyog tshaj plaws.
Laser welding ua kom nrawm txheej txheem ntawm kev hloov cov forged seem nrog lub cev stamping. Kev siv laser vuam tuaj yeem txo qis ntawm ncej puab dav thiab qee qhov ntxiv dag zog, thiab tseem tuaj yeem nyem qhov ntim ntawm cov qauv ntawm lub cev. Tsuas yog cov khoom no thiaj tuaj yeem txo qhov hnyav ntawm lub cev tsheb los ntawm txog 50 kg. Ntxiv mus, laser vuam thev naus laus zis tuaj yeem ua kom qhov chaw txuas vuam txuas mus txog qib molecular ntawm qhov sib koom tes, uas ua kom zoo dua qhov kev nruj thiab kev sib tsoo ntawm lub tsheb lub cev, thiab ua tau zoo txo lub suab nrov hauv tsheb.
Qhov zoo ntawm cov tshuab ua lub ntsej muag nqa laser:
Piv nrog rau kev vuam vias ib txwm siv thiab fusion welding txheej txheem, kev ua kom raug tseeb ntawm lub cav tsheb laser vuam yog ob npaug. Vim tias qhov nqaim ntawm qhov dav ntawm lub vuam laser txuas, cov chaw kub no me me tseem ua rau cov thermal deformation me me. Lub zog thiab loj ntawm lub teeb tsom laser raug hloov kho raws li kev ua tiav, thiab laser txiav vuam tshuab cov khoom hloov sib hloov tib lub sijhawm, kev soj ntsuam tiag tiag ntawm cov txheej txheem ua tiav, kom ua tiav ntau yam ntawm kev thov muaj peev xwm. Thaum lub zog-xeev laser siv, lub laser tuaj yeem hloov pauv mus rau qhov kev ua haujlwm, kom lub zog ntawm cov khoom siv thiab kev ua khoom siv tuaj yeem ua rau sib nrug tsis muaj teeb meem. Lub vov nqaj tsis ua rau tsis muaj hnav, thiab tuaj yeem ua haujlwm stably ntev ntev.
Qhov tsis zoo ntawm lub cav tsheb laser welding:
Kev sib dhos qhov tseeb ntawm qhov weldment yog qhov yuav tsum tau ua, thiab txoj haujlwm ntawm lub nqaj ntawm lub chaw ua haujlwm yuav tsum tsis txhob txav deb. Qhov no vim tias qhov chaw me me tom qab laser tsom xam yog qhov me me thiab lub weld nqaim. Yog tias qhov ua haujlwm qhov sib dhos qhov tseeb lossis qhov teeb tsa cov chaw tau ua haujlwm tsis raug raws li qhov yuav tsum tau ua, nws yog ib qho yooj yim ua rau vuam tsis xws luag.
