Tsib Lub Tshuab Laser Welding Tseem Ceeb hauv Kev Tsim Tsheb
Cov thev naus laus zis laser vuam muaj cov txheej txheem ua haujlwm tau zoo thiab muaj kev ywj pheej zoo heev. Hauv cov txheej txheem tsim tsheb, nws siv tau rau kev vuam lub cev tsheb thiab ntau yam khoom siv hauv tsheb. Nws txo qhov hnyav tag nrho ntawm lub cev tsheb, txhim kho qhov tseeb ntawm kev sib dhos lub cev, thiab ua tau raws li kev xav tau ntawm kev lag luam tsheb rau kev tsim qauv sib dua thiab kev ua haujlwm zoo dua. Lub caij no, nws txo cov nqi sib dhos thiab stamping hauv kev tsim tsheb thiab txhawb qib kev sib koom ua ke ntawm lub cev tsheb.
1. Laser Autogenous Vuam
Hauv kev siv tshuab laser vuam, laser autogenous welding yog hais txog cov txheej txheem uas ob lossis ntau qhov workpieces raug sib xyaw ua ke rau hauv ib daim khoom khov los ntawm kev yaj thiab tom qab ntawd khov, ua tiav qhov vuam zoo. Txoj kev vuam no tsis tas yuav tsum muaj cov dej vuam, yog li txuag cov nqi vuam. Thaum ua haujlwm tiag tiag, lub teeb laser ua rau qhov kub ntawm qhov chaw vuam nce mus rau nws qhov kub npau npau; cov hlau ua pa ces tsim lub qhov tseem ceeb. Lub qhov tseem ceeb tsis tob zuj zus thaum lub zog rov qab ntawm cov hlau vapor sib npaug rau qhov nro ntawm qhov chaw thiab lub ntiajteb txawj nqus ntawm cov hlau yaj. Laser tob tob vuam tiav thaum lub qhov tseem ceeb ruaj khov thiab kaw. Tam sim no, laser autogenous welding yog siv dav hauv kev tsim tsheb, feem ntau yog rau kev vuam tailor, kev sib dhos vuam ntawm lub cev tsheb thiab kev vuam ntawm ntau yam khoom.
2. Kev Vuam Hlau Uas Muaj Laser
Lub hauv paus ntsiab lus ntawm kev vuam hlau laser-filled hauv laser vuam thev naus laus zis yog ntxiv cov hlau vuam tshwj xeeb rau hauv qhov sib koom ua ke, uas yog yaj los ntawm lub teeb laser los tsim ib qho sib koom ua ke. Piv nrog rau cov txheej txheem vuam uas tsis yog hlau-filled, laser-filled welding muaj qhov zoo sib xws: nws nthuav dav qhov kev siv ntawm laser vuam, ua rau kev vuam ntawm cov phaj tuab nrog lub zog qis, thiab xa cov txiaj ntsig vuam zoo dua. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum siv laser-filled welding, ob qho tib si hlau filler thiab cov hlau hauv paus yuav tsum tau yaj. Qhov no tsim ib lub qhov tseem ceeb hauv cov hlau hauv paus, tso cai rau cov hlau filler thiab cov hlau hauv paus kom sib xyaw tag nrho thiab tsim cov pas dej sib xyaw ua ke tshiab. Cov pas dej sib xyaw ua ke sib txawv ntawm cov hlau filler thawj thiab cov hlau hauv paus, uas tuaj yeem kho qee qhov tsis zoo ntawm cov hlau hauv paus nws tus kheej. Kev siv cov hlau filler nrog cov khoom sib xyaw ua ke ua kom ntseeg tau tias qhov sib koom ua ke muaj kev hnav siab thiab kev tiv thaiv corrosion.
3. Kev Siv Laser-Arc Hybrid Vuam
Kev siv laser-arc hybrid welding hauv laser welding technology sib xyaw ua ke lub laser cua sov nrog lub electric arc, uas ua haujlwm ua ke ntawm ib lub pas dej molten kom ua tiav kev vuam. Hauv kev tsim cov tsheb Audi hauv lub teb chaws Yelemees, cov txheej txheem laser-arc hybrid welding yog siv rau kev vuam ntawm lub cev txhuas-ib qho ntawm cov khoom tseem ceeb tshaj plaws. Lub cev txhuas-aluminium yog rau lub tsheb Audi A8 series thib ob, tsim los ua kom muaj kev nyab xeeb thiab tiv taus torsional deformation. Cov pob qij txha vuam tsim los ntawm laser-arc hybrid welding ua tau raws li tag nrho cov kev xav tau tsim no, qhia txog kev tawv siab, lub zog zoo dua thiab kev nkag mus tob. Txhawm rau kom tau raws li cov neeg siv khoom xav tau siab rau tus qauv no, txhua qhov kev tsim khoom tau ua kom zoo kom ntseeg tau tias lub tsheb zoo tshaj plaws. Cov pob qij txha vuam nqaim ntawm laser hybrid welding yog qhov tsim nyog rau cov khoom siv nrog cov kev xav tau zoo nkauj, tshem tawm qhov xav tau los sau cov pob qij txha ces kaum ntawm sab saum toj ntawm lub cev nrog cov yas strips. Hauv kev tsim tsheb sib dua, txhua qhov kev xav tau thiab cov xwm txheej tshwj xeeb yuav tsum tau ua tiav, thiab kev tsim cov lub cev txhuas-aluminium ua rau cov qauv nruj dua rau cov kev xav tau no.
4. Laser Chaw Taws Teeb Vuam
Kev pab los ntawm lub taub hau galvanometer scanning ceev ceev, laser remote welding hauv laser welding technology ua rau kev ua tiav thiab vuam ntawm cov khoom nrog laser beams ntawm ntau lub zog. Ua tsaug rau nws cov txiaj ntsig tshwj xeeb, nws tam sim no siv dav hauv kev vuam ntawm panoramic sunroofs rau Mercedes-Benz thiab sab panels rau Volkswagen thiab Audi. Daim ntawv thov ntawm laser remote welding hauv kev tsim tsheb tam sim no muaj cov txiaj ntsig hauv qab no:
(1) Qhov tseeb ntawm qhov chaw siab thiab qhov ceev ntawm kev vuam, ua tau raws li qhov xav tau ntawm cov tuam txhab tsheb.
(2) Kev vuam hloov tau rau ntau yam kev xav tau ntawm cov qauv sib txawv thiab cov duab sib koom ua ke uas hloov kho tau.
Txawm li cas los xij, kev siv laser vuam deb muaj qhov yuav tsum tau siv cov ntaub ntawv thiab cov khoom siv ntau heev. Nws tsis tuaj yeem txo qhov nkag mus ntawm qhov vuam thaum vuam cov khoom tuab, ua rau lub zog shear qis ntawm qhov sib koom ua ke.
5. Kev Siv Laser Brazing
Cov thev naus laus zis laser brazing hauv cov thev naus laus zis laser vuam muaj qhov zoo ntawm qhov tiav zoo nkauj, hermeticity zoo heev thiab lub zog sib koom ua ke siab. Cov khoom siv laser brazing feem ntau koom ua ke lub taub hau ua brazing rau hauv caj npab robotic. Lub teeb laser yog tsom mus rau qhov sib koom ua ke ntawm cov hlau ntawv, yaj cov hlau brazing (piv txwv li, tooj liab-silicon brazing hlau) los koom ua ke cov khoom ua ke. Kev vam meej ntawm txoj kev ua tiav no nyob rau hauv nws lub zog sib koom ua ke ze rau ntawm cov pob qij txha welded, nrog rau qhov zoo nkauj ntawm nws cov welds. Cov pob qij txha vuam tsim los ntawm laser brazing yog nto moo rau lawv qhov siab hermeticity thiab du, huv si tiav, txhais tau tias cov khoom brazed yuav luag tsis tas yuav rov ua dua. Piv txwv li, lub cev tsheb tuaj yeem pleev xim ncaj qha tom qab ntxuav.
Rau kev lag luam tsim khoom tsheb, txhua yam ntawm cov nocov txheej txheem vuam lasermuaj nws tus nqi siv tshwj xeeb. Kev xaiv txoj kev vuam tsim nyog rau ntau qhov chaw ntawm lub tsheb pab txhim kho qhov zoo ntawm kev tsim khoom, thaum tseem ua tau raws li cov kev xav tau ntawm cov tuam txhab tsheb rau kev vuam tus nqi thiab kev ua haujlwm zoo.
