Yog vim li cas vim li cas laser -arc hybrid vuam tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau kev tsim khoom hauv aerospace yog tias nws daws tau qhov teeb meem ntawm kev sib tsoo ntawm cov khoom siv loj thiab cov khoom sib txawv. Thaum tsim cov fuselage panels lossis foob pob hluav taws roj tso tsheb hlau luam, cov thev naus laus zis no siv lub peev xwm ntawm cov khoom siv hluav taws xob kom them nyiaj rau cov khoom sib dhos uas tsis muaj kev cuam tshuam nrog ntev weld seams, txo cov kev cai nruj rau cov cuab yeej raug. Lub caij no, laser- taw qhia arcs ua tiav kev nkag mus tob, ua kom muaj qhov nruab nrab- cov phaj tuab los ntawm ib qho kev sib txuas ntawm ib sab mus rau ob sab - sab duab nrog cov cua kub qis heev, txo qis deformation nyob rau hauv nyias - cov khoom siv phab ntsa thiab ua kom cov duab aerodynamic precision. Tsis tas li ntawd, kev sib koom ua ke ntawm cov khoom siv hluav taws xob ua kom zoo dua lub voj voog thermal ntawm lub pas dej molten, ua kom cov pa khiav tawm, ua kom cov porosity thiab cracking defects ntau nyob rau hauv siab - zog alloys, thiab ua tiav ib tug zoo meej ua ke ntawm high efficiency thiab high quality.
Laser -arc hybrid vuam, nrog nws qhov zoo ntawm kev nkag mus tob thiab kev hloov pauv siab, tau dhau los ua cov cuab yeej tseem ceeb hauv kev tsim khoom siv dav hlau niaj hnub no. Los ntawm cov txheej txheem ntawm daim tawv nqaij thiab foob pob hluav taws tso tsheb hlau luam mus rau cov khoom siv cav, cov txheej txheem no tau siv dav rau cov ntaub ntawv tseem ceeb xws li txhuas, titanium thiab siab - kub alloys, txhawb kev dhia mus rau kev sib xyaw ua ke, sib sib zog nqus thiab siab - ua haujlwm tom ntej - tiam aircraft. Hauv kev tsim dav hlau loj, cov thev naus laus zis no hloov cov tsoos riveting rau ob npaug -sab synchronous vuam ntawm cov qauv fuselage thiab tawv. Los ntawm kev ua haujlwm siab - vuam ceev kom sib npaug ntawm cov khoom siv hluav taws xob, nws txo cov vaj huam sib luag deformation; lub sijhawm no, los ntawm kev siv arc hlau pub rau kev them nyiaj rau kev sib dhos tsis raug, nws ua kom qhov zoo ntawm ultra- ntev welds, ua tiav cov qauv kev sib koom ua ke thiab qhov hnyav hnyav heev.
Rau kev vuam ntawm siab -lub zog aluminium alloy cylindrical seem ntawm cryogenic roj tso tsheb hlau luam (kua hydrogen / kua oxygen) nyob rau hauv lub tsheb pib, laser-arc hybrid welding feem ntau yog siv los daws qhov teeb meem ntawm ib leeg -sab vuam nrog ob npaug -sided daim hlau.} ntawm qhov nruab nrab Hauv qhov xwm txheej no, cov khoom siv hluav taws xob sib xyaw nkag mus rau lub phaj los ntawm cov txiaj ntsig keyhole, thaum lub arc kis mus rau saum npoo thiab ntxiv cov ntsiab lus alloying. Qhov kev sib xyaw ua ke no tsis tsuas yog ua kom cov vuam ua tau zoo los ntawm 3-5 zaug tab sis, qhov tseem ceeb tshaj, los ntawm kev tswj qhov kub thiab txias ntawm lub pas dej molten, ua kom cov porosity thiab kev sib koom ua ke softening uas yuav tshwm sim nyob rau hauv aluminium-lithium alloys, ho txhim kho qhov qis -tej qhov kub thiab txias reweld tank. Nyob rau hauv aerospace cav sector, laser{13}} arc hybrid vuam yog tsuas yog siv rau kev koom tes thiab kho cov titanium alloy casings, stator hniav, thiab combustion chamber Cheebtsam. Vim tias titanium alloys tsis tshua muaj siab rau cov pa oxygen, hydrogen, thiab nitrogen ntawm qhov kub thiab txias thiab muaj cov thermal conductivity tsis zoo, cov tsoos arc vuam tau yooj yim ua rau cov nplej ntxhib thiab cov cua sov ntau dhau - thaj chaw cuam tshuam. Hybrid welding siv lub zog muaj zog ntawm lub laser kom muaj kev nkag mus tob thaum txo qis tag nrho cov khoom siv hluav taws xob, txo qhov kub ntawm qhov cuam tshuam thiab txo qhov cuam tshuam lub sij hawm rau qhov kub thiab txias. Tsis tas li ntawd, qhov kev pab cuam ntawm lub arc txhim kho qhov zoo ntawm qhov vuam, txo qhov tsis xws luag xws li undercutting, muab kev ruaj ntseg zoo heev rau cov khoom siv cav uas ua rau siab kub, siab siab, thiab lub voj voog siab.
Txawm hais tias laser- arc hybrid vuam qhia tau hais tias muaj peev xwm zoo hauv kev lag luam aerospace, nws txoj kev siv dav dav tseem ntsib ob qho tib si kev thiab cov nqi txwv. Ua ntej, kev sib txuas ntawm cov txheej txheem tsis sib xws yog qhov nyuaj heev, nrog ntau tshaj kaum qhov tsis xws li lub zog laser, qhov chaw txoj kab uas hla, arc tam sim no, qhov hluav taws xob, qhov sib txawv ntawm cov xov hlau, thiab qhov defocusing tus nqi sib cuam tshuam nrog ib leeg, uas ua rau lub qhov rais nqaim uas txawm tias qhov hloov pauv me me tuaj yeem ua rau vuam tsis ruaj khov. Qhov thib ob, tus nqi ntawm cov khoom siv sib xyaw ua ke thiab kev saib xyuas yog qhov siab, vim tias kev sib xyaw ua ke ntawm siab - lub zog lasers thiab precision vuam robots yuav tsum tau nqis peev tseem ceeb thiab xav tau qib siab ntawm cov neeg siv kev txawj ntse. Saib tom ntej, thev naus laus zis yuav tsum tsim kho raws li hauv qab no: (1) kev koom ua ke AI thiab ntau-sensor fusion technologies (visual, spectral, acoustic) kom ua tiav "kaw- voj tswj" ntawm cov txheej txheem vuam. Lub kaw lus tuaj yeem hnov qhov sib txawv ntawm kev sib txawv los yog lub pas dej molten hauv lub sijhawm tiag tiag thiab tuaj yeem kho laser lossis arc tsis nyob hauv milliseconds, daws cov teeb meem kev ruaj ntseg.
(2) Nrog rau kev nce hauv lub zog ntawm xiav thiab ntsuab lasers, kev sib xyaw vuam ntawm cov ntaub ntawv zoo heev rau aerospace aluminium thiab tooj liab alloys yuav ua tiav los ntawm 'short wavelength + arc' txoj kev, ntxiv kev txhim kho lub zog nqus thiab vuam stability. (3) Qhov kev thov rau cov qauv- kev ua haujlwm sib koom ua ke hauv aerospace tau loj hlob, thiab yav tom ntej kev sib txuas vuam yuav nce siab rau kev sib koom ua ke ntawm cov hlau tsis sib xws xws li steel-aluminium thiab titanium-aluminium, tawg los ntawm metallurgical incompatibility bottlenecks los ntawm cov khoom siv hluav taws xob, lub teeb pom kev zoo thiab kev tswj xyuas qhov tseeb. tiam tom ntej ntawm aircraft.
