Lub laser xiav, raws li cov kev taw qhia tshiab hauv kev lag luam ntawm semiconductor lasers, tau txhim kho qhov nqus ntawm cov ntaub ntawv hlau xim xws li tooj liab, kub, thiab txhuas los ntawm ob peb mus rau kaum zaus piv rau ze-infrared wavelength lasers. Nrog rau qhov kev thov ntau ntxiv rau cov khoom siv laser zoo hauv kev lag luam, kev ua haujlwm siab xiav lub teeb tau maj mam siv rau hauv cov khoom tsim xws li vuam, kev kho cua sov, thiab kev tsim khoom ntxiv nrog rau kev lag luam dav dav. Tsab ntawv xov xwm no txheeb xyuas qhov zoo ntawm lub zog siab thiab lub teeb ci xiav lasers hauv kev ua cov khoom siv, sau cov keeb kwm kev loj hlob ntawm xiav semiconductor lasers thiab lawv cov kev siv tam sim no hauv cov hlau ua teb, thiab tso rau pem hauv ntej qee qhov kev xav ntawm kev txhim kho yav tom ntej ntawm high-power xiav lasers.
Semiconductor laser yog ib hom khoom siv hluav taws xob hloov kho qhov muag, uas tau ua tiav kev loj hlob sai thiab cov txiaj ntsig tau zoo hauv 50 xyoo dhau los, thiab muaj kev nkag mus dav dav thiab siv hauv kev tshawb fawb tshawb fawb thiab engineering technology. Nws siv cov khoom siv semiconductor raws li qhov nce nruab nrab, los ntawm lub hauv paus ntsiab lus ntawm electrons nyob rau hauv kev hloov ntawm lub zog theem ntawm lub teeb, kev siv lub resonant kab noj hniav muaj li ntawm semiconductor crystals thiab parallel tsom iav, nyob rau hauv cov hluav taws xob txhaj tshuaj mus cuag lub teeb oscillation, tawm tswv yim, thiab thaum kawg tsim lub teeb hluav taws xob amplification, thiaj li ua tiav cov zis laser.
Raws li kev taw qhia tshiab hauv semiconductor laser teb, xiav laser tau tsim ntau daim ntawv thov sai hauv xyoo tas los no. Ntawm lawv, ua tsaug rau qhov tshwj xeeb zoo ntawm 450nm luv-yoj ntu, piv nrog ze-infrared wavelength lasers, tus nqi nqus rau cov ntaub ntawv tsis-ferrous (tshwj xeeb yog tooj liab thiab kub) tau nce los ntawm ntau zaus mus rau kaum tawm zaus. Kev ua haujlwm siab xiav lub teeb pom kev zoo muab cov thev naus laus zis tshiab rau kev ua haujlwm laser zoo ntawm cov khoom siv hlau tsis muaj hlau xws li tooj liab thiab kub, thiab tseem ua rau cov cuab yeej no tuaj yeem siv dav hauv kev lag luam hauv teb chaws thiab kev tiv thaiv tub rog xws li cov khoom siv, Cov neeg siv khoom siv hluav taws xob, tsheb thiab lub zog tshiab, thiab muaj kev lag luam dav dav, thiab tau dhau los ua qhov siab tshaj plaws ntawm kev sib tw thoob ntiaj teb hauv laser teb. Ib tug xov tooj ntawm domestic kev tshawb fawb units thiab cov lag luam ua hauj lwm rau lub hwj chim GaN raws li xiav ray semiconductor laser chips.
Vuam yam ntxwv ntawm xiav laser rau non-ferrous teb
Copper laser welding tshuab yog qhov zoo tshaj plaws xav txog qhov zoo ntawm xiav laser nyob rau hauv vuam teb. Vim hais tias qhov nqus ntawm tooj liab mus rau ze-infrared laser yog tsawg heev, tus nqi nqus fluctuates zoo heev, thiab cov tooj liab nws tus kheej muaj thermal conductivity zoo, nws yog ib qho yooj yim los tshwm tsis zoo weld tsim, yooj yim deformation, kub tawg, spatter, porosity thiab lwm yam vuam tsis xws luag thaum laser vuam. Ib qho kev ua tiav hauv laser vuam tshuab ntawm tooj liab liab tau ua tiav los ntawm kev siv lub siab nqus tus nqi ntawm liab tooj liab rau xiav laser. Nyob rau hauv cov txheej txheem vuam, lub zog tuaj yeem hloov pauv sai sai rau hauv lub zog hluav taws xob, ua rau lub melting ntawm tooj liab nto thiab tsim ib lub pas dej molten, thiab tom qab ntawd cov cua sov tau hloov mus rau sab hauv ntawm lub workpiece los ntawm kev kub nyhiab, thiaj li. ua tiav cov nyhuv vuam yam tsis muaj txaws thiab porosity.
Lub xiav laser vuam siv lub Kaplin xiav laser ua lub teeb qhov chaw, nruab nrog collimated tsom vuam lub taub hau, fiber-xiav puas welding taub hau thiab rooj, uas muaj peev xwm paub ntau yam kev nruam thiab mem tes vuam txoj kev. Lub kaw lus ua tau zoo nyob rau hauv lub puab tsaig thiab lub taub qab vuam, tshwj xeeb tshaj yog rau vuam ntawm cov ntaub ntawv zoo heev xws li tooj liab, kub, stainless hlau thiab alloys.
Kev siv nws (los yog Ar) roj los ua ib qho chaw tiv thaiv hauv cov txheej txheem vuam xyuas cov txheej txheem vuam nyob rau hauv cov nqi sib txawv, vuam ceev, lub zog thiab defocus. Lub laser xiav tuaj yeem tsis tsuas yog ua ntau txheej vuam ntawm cov ntawv ci tooj liab nrog lub thickness ntawm 20μm, tab sis kuj ua tiav 0.3mm, 0.6mm thiab lwm yam thickness ntawm tooj liab taub qab vuam. Thaum lub sij hawm vuam txheej txheem, qhov saum npoo ntawm lub vuam yog ruaj khov, tsis muaj txaws, thiab nto yog du; Nyob rau hauv 40X microscope, tsis muaj pores tau pom nyob rau hauv lub vuam. Ntxiv rau laminated tooj liab thiab pob tw vuam, nyob rau hauv lub zog tshiab electrode hairpin, hluav taws xob nti beryllium bronze tus pin vuam, xiav laser muaj kev ua haujlwm zoo heev. Xav tias lub teeb xiav tsis tuaj yeem ua tiav qhov sib sib zog nqus nqus vuam thiab lub teeb pom kev loj, peb tshawb xyuas cov ntawv thov sib xyaw ntawm lub teeb xiav thiab lub teeb liab. Lub teeb liab tuaj yeem ua tiav lub taub me me thiab lub zog siab los txhim kho qhov tob ntawm kev nkag mus, thaum lub teeb xiav siv lub siab nqus ntawm tooj liab kom yaj cov khoom sai sai thaum txhim kho qhov nqus ntawm lub teeb liab. Tsis tas li ntawd, qhov chaw loj ntawm lub teeb xiav kuj tseem tuaj yeem nthuav dav lub pas dej molten thiab ncua lub solidification ntawm lub pas dej molten, yog li ua tiav tsis tshua muaj spatter, tsis tshua muaj porosity thiab zoo welding rau ib qho twg.
Blue laser kuj muaj qee qhov zoo hauv vuam stainless hlau. Vim lub siab nqus ntawm lub teeb xiav hauv cov hlau tsis muaj steel, lub laser xiav tuaj yeem hloov lub zog mus rau hauv tshav kub, sai yaj lub stainless hlau nto, thiab ua tiav vuam zoo. Nyob rau tib lub sijhawm, lub xiav laser muaj lub zog hluav taws xob ntau dua thiab thaj chaw kub, uas yog kho qhov chaw vuam, yog li kev txhim kho lub vuam zoo.
Rau kev vuam ntawm txhuas thiab tooj liab-aluminium cov ntaub ntawv sib xyaw, xiav laser kuj muaj qee qhov kev siv tau. Cov ntaub ntawv txhuas muaj qhov nqus tsawg tsawg ntawm lub teeb xiav, tab sis nrog lub zog ceev thiab qhov chaw zoo, xiav laser kuj tuaj yeem ua tiav vuam zoo ntawm cov ntaub ntawv txhuas. Tsis tas li ntawd, kev sib xyaw ua ke ntawm lub teeb xiav thiab lub teeb liab laser tuaj yeem suav tias yog daim ntawv thov sib xyaw los txhim kho cov nyhuv vuam ntawm cov ntaub ntawv txhuas kom kov yeej qhov kev txwv ntawm lub teeb xiav xiav nqus ntawm cov ntaub ntawv txhuas [3]. Xav txog cov yam ntxwv ntawm cov khoom siv thiab cov yam ntxwv laser, lub teeb xiav laser haum rau txhuas vuam tuaj yeem tsim los ua kom tau raws li qhov xav tau ntawm cov ntawv thov sib txawv.
Tsis tas li ntawd, lub teeb xiav kuj muab qhov muaj peev xwm tshiab rau tooj liab-aluminium composite welding, vim qhov kub ntawm infrared laser vuam, ua rau muaj ntau cov nkig intermetallic compounds thaum tooj liab-aluminium composite, composite daim ntawv thov ntawm lub teeb xiav thiab lub teeb liab. laser kuj tseem tuaj yeem ua lub luag haujlwm hauv kev vuam ntawm tooj liab-aluminium cov ntaub ntawv los txhim kho vuam zoo thiab ua haujlwm zoo.
