Los ntawm Beam Shaping, peb feem ntau txhais tau hais tias kev siv beam shaping lo ntsiab muag, lo ntsiab muag, microlenses los yog sib txawv zoo li tus fibers kom ua tau ib homogenizing nyhuv ntawm lub teeb. Ntawm no peb qhia txog ib txoj kev tshiab: BrightLine vuam thev naus laus zis los ntawm TRUMP, siv 2-hauv-1 fiber ntau (Daim duab 1), uas yog tsim los ntawm cov tub ntxhais fiber ntau sab hauv thiab lub nplhaib fiber ntau sab nraud. Ob lub beams yog superimposed los ua rau ntawm qhov chaw ua haujlwm.

Nyob rau hauv cov txheej txheem sib sib zog nqus, cov hlau nyob rau hauv qhov chaw me me yog yaj thiab vaporized los ntawm laser cua sov, ua kom muaj zog siab nyob rau hauv qab ntawm lub qhov me me. Cov chav yog ejected los ntawm hauv qab uas ua rau cov khoom poob, kuj hu ua spatter. Tag nrho cov txheej txheem zoo ib yam li cov dej kub hauv tsev uas tsis tu ncua ua npuas. Thaum siv lub 2-hauv-1 shaping beam, lub nplhaib sab nrauv fiber ntau muab thaj tsam loj ntawm "buffer" nyob ib ncig ntawm micro-aperture, tso cai rau lub siab vapor kom dim. Lub nplhaib sab nraud pab tsim cov txheej txheem vuam ruaj khov dua nrog kev sib sib zog nqus.
Nyob rau tib lub sijhawm, lub nplhaib sab nraud hloov pauv cov kev taw qhia ntawm lub pas dej molten hlau ua kua (Daim duab 2). Lub nrawm nrawm ntawm molten hlau mus rau saum npoo yog deflected rau sab hauv qab ntawm lub nplhaib beam mem tes. Yog li ntawd, nyob rau hauv kev sib xyaw ua ke ntawm ob qho kev hloov pauv saum toj no, nws tau sim ua pov thawj tias cov txheej txheem sab hauv thiab sab nrauv fiber ntau tuaj yeem txo qhov tawg ntawm 90 feem pua.

Lub beam oscillation trajectory yog qhia hauv daim duab hauv qab no. Rau qee qhov txheej txheem vuam pob tw thiab ceg tawv, qhov twg muaj qhov sib txawv ntawm qhov chaw thiab tsis muaj cov khoom siv muab tub lim, thiab cov khoom siv laser vuam ua raws li txoj kab ncaj nraim ntawm qhov sib txawv, nws tsis tuaj yeem vuam zoo. Yog li ntawd, beam oscillation (Oscillation los yog Wobble) yog coj los rau hauv, qhov twg cov kab ncaj thiab nce thiab nqis txav yog superimposed los tsim ib tug kauv (Daim duab 3), ua rau lub pas dej ua ke molten qhov twg cov hlau ua kua nyob rau hauv qhov sib txawv rau welding. Kev siv cov nqaj oscillation muaj qhov txiaj ntsig ntxiv ntawm kev them nyiaj rau qhov tsis raug ntawm qhov seem, txo qhov porosity thiab ua kom zoo nkauj ntawm cov vuam thiab kev ruaj ntseg ntawm cov txheej txheem vuam.

Kev siv cov beam shaping thiab beam oscillation tuaj yeem txhim kho kev ruaj ntseg ntawm kev sib sib zog nqus vuam txheej txheem, weldability ntawm aluminium alloys thiab high-strength steels, thiab tsis txhob microcracking zoo. Txawm li cas los xij, rau qee cov ntaub ntawv, random micro-cracking tseem muaj. Cov duab 4-6 hauv qab no qhia qhov kev ua tau zoo ntawm 6XXX series aluminium alloy nyob rau hauv peb cov xwm txheej ntawm beam shaping, beam oscillation, thiab beam shaping and oscillation.
