Lua ikeelectron beam vuam(EBW), laser beam welding muaj zog ceev (ntawm qhov kev txiav txim ntawm 1 MW / cm2) ua rau me methaj chaw muaj kev kub ntxhovthiab cov cua kub thiab cua txias siab. Qhov chaw loj ntawm lub laser tuaj yeem sib txawv ntawm 0.2 hli thiab 13 hli, txawm tias tsuas yog qhov me me yog siv rau vuam. Qhov tob ntawm kev nkag mus yog proportional rau tus nqi ntawm lub zog muab, tab sis kuj yog nyob ntawm qhov chaw ntawm qhov chaw.focal point: Kev nkag mus tau zoo tshaj plaws thaum lub focal point yog me ntsis hauv qab ntawm qhov chaw ua haujlwm
Ib qho txuas txuas lossis lub teeb ci laser tuaj yeem siv nyob ntawm daim ntawv thov. Millisecond-ntev pulses yog siv los vuam cov ntaub ntawv nyias xws li rab chais hniav thaum lub tshuab laser txuas ntxiv yog ua haujlwm rau qhov sib sib zog nqus welds.
LBW yog txheej txheem ntau yam, muaj peev xwm vuamcarbon hlau, HSLA hlau, stainless hlau, aluminium, thiabtitanium. Vim muaj cov cua txias siab, kev tawg yog ib qho kev txhawj xeeb thaum vuam high-carbon steels. Weld zoo yog siab, zoo ib yam li ntawmelectron beam vuam. Qhov ceev ntawm vuam yog proportional rau tus nqi ntawm lub hwj chim muab, tab sis kuj nyob ntawm seb hom thiab thickness ntawm lub workpieces. Lub zog muaj peev xwm ntawmgas lasersua rau lawv tshwj xeeb tshaj yog haum rau cov ntawv thov ntim siab. LBW tshwj xeeb tshaj yog nyob rau hauv kev lag luam automotive.
Qee qhov zoo ntawm LBW piv rau EBW yog raws li hauv qab no:
- lub teeb laser tuaj yeem kis tau los ntawm huab cua es tsis xav tau lub tshuab nqus tsev
- cov txheej txheem yog yooj yim automated nrogrobotic tshuab
- x-rays tsis tsim
- LBW ua rau cov welds zoo dua
A derivative of LWB,laser-hybrid vuam, sib txuas cov laser ntawm LBW nrog rau arc vuam txoj kev xws ligas hlau arc vuam. Qhov kev sib xyaw ua ke no tso cai rau kev ua haujlwm yooj yim dua, txij li GMAW muab cov hlau molten los sau cov kev sib koom ua ke, thiab vim yog siv lub laser, ua rau cov vuam nrawm dua li qhov uas ib txwm ua tau nrog GMAW. Weld zoo zoo li yuav siab dua ib yam nkaus, vim qhov muaj peev xwm rau undercutting raug txo.
