Tam sim no, nyob rau hauv lub tshav pob ntawm hlau welding, handheld laser vuam tshuab yog dav siv. Yeej, cov hlau uas tuaj yeem welded los ntawm cov tsoos vuam yuav raug welded los ntawm laser, thiab cov nyhuv vuam thiab ceev yuav zoo dua li tsoos vuam tshuab. Kev siv vuam ib txwm yog qhov nyuaj rau kev vuam cov ntaub ntawv tsis-ferrous xws li aluminium alloy, tab sis laser vuam muaj qhov dav dua, thiab aluminium alloy thiab lwm yam ntaub ntawv kuj tuaj yeem yooj yim welded. Nyob rau hauv cov nqe lus ntawm welding hlau cov ntaub ntawv, tes tuav laser vuam tshuab kuj muaj ib co ntsiab lus yuav tsum xyuam xim rau.
Ua ntej tshaj plaws, ua tib zoo saib xyuas seb lub teeb pom kev zoo ntawm lub qhov rooj kaw puas huv si, lub lens tsis huv yuav tawg sai sai thaum siv. Nyob rau ntawm lub sijhawm no, kev hloov kho ntawm lub laser feem ua tiav. Laser Nrog txoj kev loj hlob ntawm laser vuam tshuab, thev naus laus zis ntawm laser vuam tshuab tau loj hlob ib hnub dhau ib hnub, thiab daim ntawv thov kev lag luam tau txuas ntxiv mus. Txawm li cas los xij, hauv cov txheej txheem vuam tiag tiag, ntau yam teeb meem tseem yuav tshwm sim vim muaj ntau yam laj thawj. Yog li ntawd, yuav ua li cas tswj cov tsos ntawm cov teeb meem no thiab yuav ua li cas los daws cov teeb meem zoo no tau dhau los ua qhov tseem ceeb tshaj plaws ntawm kev tsim khoom thiab kev ua haujlwm. Rau cov khoom uas tuaj yeem ua tiav, peb txheeb xyuas qhov ua tau raws li qhov tshwm sim ntawm vuam. Feem ntau hais lus, muaj ob qho laj thawj rau kev ua haujlwm tsis zoo, ua cov khoom siv teeb meem, siv laser vuam tshuab los hloov cov khoom siv rau kev sau, tuaj yeem daws qhov teeb meem zoo li no. Hom thib ob, kev teeb tsa ntawm cov kev tsis sib xws, yuav tsum muaj kev ntsuam xyuas tas li ntawm tib yam raws li cov khoom yuav tsum tau welded, thiab kev sib tham raws li cov txiaj ntsig vuam uas tshwm sim tsis tu ncua.
Kev nyab xeeb siab, qhov vuam taub tsuas yog siv tau thaum qhov hloov pauv tau kov thaum nws kov cov hlau, thiab qhov kov hloov pauv muaj lub cev ntsuas kub.
Nws tuaj yeem paub qhov vuam ntawm txhua lub kaum ntse ntse, thiab tuaj yeem vuam ntau yam welded workpieces thiab cov duab tsis sib xws ntawm cov khoom loj dua. Paub welding ntawm txhua lub kaum ntse ntse.
Nws tseem tuaj yeem tswj xyuas qhov chaw ua haujlwm huv thiab huv hauv cov nroj tsuag. Siv tus phooj ywg tsim tsim rau laser welding kom optimize cov txheej txheem hlau ntau lawm. Piv nrog cov tsoos welding, laser welding muaj qhov zoo, tab sis laser vuam kuj muaj cov kev xav tau siab dua ntawm kev ua haujlwm ua ntej ntawm cov khoom ua haujlwm thiab cov khoom siv. Txhawm rau kom siv tau qhov zoo ntawm laser vuam, txo cov nqi tsim khoom thiab muab kev ua haujlwm ntau lawm, nws yog ib qho tsim nyog yuav tsum ua kom zoo rau tag nrho cov ntawv hlau ntau lawm xws li cov khoom tsim, laser txiav, stamping, dabtsi yog khoov thiab laser vuam. Peb pom nyob rau hauv qhov tseeb ntau lawm hais tias tus nqi ntawm cov ntawv hlau cov khoom siv laser vuam tshuab, cov txheej txheem laser vuam tsis yog lub ntsiab determinant. Kev tsim khoom tiag tiag ua pov thawj tias 70% ntawm tus nqi ntawm cov khoom siv hlau yog txiav txim los ntawm cov khoom tsim. Txhawm rau txo cov nqi tsim khoom thiab txhim kho vuam efficiency, peb yuav tsum xub pib nrog cov khoom tsim. Nyob rau hauv thawj cov khoom tsim, xav txog qhov yuav tsum tau ntawm laser vuam ntawm lub workpiece, xws li txo cov txheej txheem dabtsi yog khoov nyob rau hauv ntau lawm, siv laser txiav kom ntau li ntau tau, adopting tus kheej- positioning tsim thiab thiaj li nyob.
Qhov nyuaj ntawm laser vuam tshuab vuam aluminium alloy
Aluminium alloy muaj cov yam ntxwv hauv qab no: lub teeb yuag, tsis muaj hlau nplaum, kev ua haujlwm kub tsis zoo, zoo corrosion kuj, zoo formability, thiab lwm yam, yog li nws yog dav siv nyob rau hauv ntau yam welded qauv khoom. Siv aluminium alloy es tsis txhob steel phaj cov khoom siv rau vuam, cov qauv hnyav tuaj yeem raug txo los ntawm ntau tshaj ib nrab.
Aluminium alloy vuam yog yooj yim rau pores;
Lub expansion coefficient ntawm weld kab yog loj, uas yog ib qho yooj yim mus ua welding deformation;
Aluminium alloy welding yog feem ntau ua rau kub tawg;
Aluminium alloy welded pob qij txha yog hnyav heev thiab muaj lub zog qis coefficient, uas tseem yog qhov teeb meem loj tshaj plaws uas cuam tshuam rau daim ntawv thov ntawm aluminium alloy;
Qhov saum npoo ntawm aluminium alloy yog qhov yooj yim los tsim cov yeeb yaj kiab oxide refractory (A12O3 muaj qhov melting point ntawm 2060 ° C), uas yuav tsum tau muaj cov txheej txheem vuam muaj zog;
Aluminium alloy muaj thermal conductivity loj (kwv yees li 4 npaug ntawm cov hlau), thiab nyob rau tib lub vuam ceev, cov khoom siv hluav taws xob yog 2 mus rau 4 npaug ntau dua li cov hlau welded. Yog li ntawd, vuam ntawm aluminoy xuaj zis yuav tsum tau siv cov kev ua kom zoo vuam cov qauv nrog lub zog kub, thiab cov vuam tshav kub kub, thiab ua hluav taws xob kub.
Lub zog laser tsis zoo tawm tswv yim fiber ntau laser vuam tshuab yog kev lag luam' thawj-chav kawm" lub zog tsis zoo tawm tswv yim tshuab". Nws siv lub zog fiber ntau los xa cov 1064nm laser tsim los ntawm cov khoom siv-xeev laser mus rau fiber ntau los ntawm laser coupling tshuab, thiab tom qab ntawd xa cov teeb laser hauv fiber ntau los ntawm daim iav tso zis. Ua rau ntawm qhov chaw ntawm lub workpiece kom ua tiav lub hom phiaj ntawm vuam. Kev siv cov fiber ntau kho qhov muag xa mus rau lub teeb laser tuaj yeem ua rau kev siv qhov hloov pauv ntawm cov khoom siv kho qhov muag, kom lub laser tuaj yeem ua cov haujlwm ntawm txhua lub kaum ntse ntse, paub txog kev ua haujlwm ntau yam. Cov fiber ntau optical kuj muaj homogenization ntawm lub zog laser, uas tuaj yeem tso tawm lub zog ntawm lub laser raws li cov duab ntawm lub raj, thiab homogenize lub laser, kom qhov zoo ntawm lub laser beam zoo dua thiab vuam zoo dua. Haum rau vuam ntawm ntau yam hlau thiab aluminium alloy cov ntaub ntawv.
