Ntau ntxiv txog kev siv tshuab laser welding

Kev siv tshuab laser sib koom ua ke, lossis kev siv tshuab laser vuam, siv lub zog laser siab los tsom thiab tswj kev cuam tshuam ntawm qhov chaw ntawm cov khoom siv, thiab qhov chaw ntawm cov khoom siv nqus lub zog laser thiab hloov nws mus rau hauv lub zog cua sov, ua rau cov khoom siv hauv zos sov thiab yaj, ua raws li kev txias thiab khov kom ua tiav kev sib koom ua ke ntawm cov khoom sib xws lossis sib txawv. Cov txheej txheem vuam laser xav tau lub zog laser ceev ntawm 10⁴mus txog 10⁸W/cm2²Piv rau cov txheej txheem vuam ib txwm muaj, laser vuam muaj cov txiaj ntsig hauv qab no.

Cov txheej txheem vuam laser xav tau lub zog laser ceev ntawm 10⁴mus txog 10⁸W/cm2²Piv rau cov txheej txheem vuam ib txwm muaj, laser vuam muaj cov txiaj ntsig hauv qab no.

1-plasma huab, 2-cov khoom yaj, 3-qhov tseem ceeb, 4-qhov tob ntawm kev sib xyaw
 
Vim muaj lub qhov tseem ceeb, lub teeb laser, tom qab irradiating sab hauv ntawm lub qhov tseem ceeb, yuav ua rau kom lub laser nqus tau los ntawm cov khoom siv thiab txhawb kev tsim cov pas dej molten tom qab tawg thiab lwm yam teebmeem, ob txoj kev vuam tau muab piv rau hauv qab no.
 


Daim duab saum toj no qhia txog cov txheej txheem laser vuam ntawm tib yam khoom siv thiab tib lub teeb ci, lub tshuab hloov pauv lub zog tsuas yog ua tiav los ntawm lub qhov tseem ceeb, lub qhov tseem ceeb thiab cov hlau molten ze ntawm phab ntsa ntawm lub qhov txav mus nrog kev nce qib ntawm lub teeb laser, cov hlau molten txav lub qhov tseem ceeb tawm ntawm cov huab cua tshuav tom qab kom sau thiab tom qab condensation, tsim ib qho weld seam.
 
Yog tias cov khoom siv uas yuav tsum tau vuam yog cov hlau sib txawv, qhov muaj qhov sib txawv ntawm cov khoom thermal yuav muaj kev cuam tshuam loj heev rau cov txheej txheem vuam, xws li qhov sib txawv ntawm cov ntsiab lus melting, thermal conductivity, lub peev xwm kub tshwj xeeb, thiab cov coefficients nthuav dav ntawm cov khoom sib txawv, ua rau muaj kev ntxhov siab vuam, vuam deformation, thiab kev hloov pauv ntawm cov xwm txheej crystallization ntawm cov hlau sib koom ua ke, ua rau txo qis cov khoom siv kho tshuab ntawm qhov vuam.
 
Yog li ntawd, raws li cov yam ntxwv sib txawv ntawm qhov chaw vuam, cov txheej txheem vuam tau tsim laser filler welding, laser brazing, dual-beam laser welding, laser composite welding, thiab lwm yam.

Laser Hlau Filling Vuam
Hauv cov txheej txheem laser vuam ntawm txhuas, titanium thiab tooj liab alloys, vim yog qhov nqus tsawg ntawm lub teeb laser (<10%) hauv cov ntaub ntawv no, cov duab tsim plasma muaj qee qhov kev tiv thaiv ntawm lub teeb laser, yog li nws yooj yim los tsim cov spatter thiab ua rau muaj qhov tsis zoo xws li porosity thiab tawg. Tsis tas li ntawd, qhov zoo ntawm kev vuam kuj raug cuam tshuam thaum qhov sib txawv ntawm cov workpieces loj dua qhov chaw diameter thaum lub phaj nyias sputtering.
 
Thaum daws cov teeb meem saum toj no, qhov txiaj ntsig zoo dua ntawm kev vuam tuaj yeem tau txais los ntawm kev siv txoj kev ntawm cov khoom siv filler. Cov khoom siv filler tuaj yeem yog hlau lossis hmoov, lossis siv cov txheej txheem filler uas tau teeb tsa ua ntej. Vim yog qhov chaw me me, qhov vuam yuav nqaim dua thiab muaj cov duab me ntsis convex ntawm qhov chaw tom qab cov khoom siv filler tau thov.

Laser Brazing
Tsis zoo li kev vuam fusion, uas yaj ob qhov chaw vuam tib lub sijhawm, brazing ntxiv cov khoom siv filler nrog qhov melting point qis dua li cov khoom siv hauv paus rau ntawm qhov chaw vuam, yaj cov khoom siv filler kom puv qhov sib txawv ntawm qhov kub qis dua qhov melting point ntawm cov khoom siv hauv paus thiab siab dua qhov melting point ntawm cov khoom siv filler, thiab tom qab ntawd condenses los ua ib qho weld khov kho.
 
Kev sib txhuam yog qhov tsim nyog rau cov khoom siv hluav taws xob uas rhiab heev rau cua sov, cov phaj nyias nyias, thiab cov ntaub ntawv hlau uas hloov pauv tau.
 
Ntxiv mus, nws tuaj yeem raug cais ntxiv ua brazing mos (<450 °C) thiab brazing nyuaj (>450 °C) nyob ntawm qhov kub uas cov khoom siv brazing raug cua sov.

Dual Beam Laser Vuam
Kev vuam ob txoj kab hluav taws xob tso cai rau kev tswj hwm lub sijhawm thiab qhov chaw ntawm laser irradiation yooj yim thiab yooj yim, yog li kho qhov kev faib hluav taws xob.
 
Nws yog siv rau laser vuam ntawm txhuas thiab magnesium alloys, splice thiab lap phaj vuam rau tsheb, laser brazing thiab sib sib zog nqus fusion vuam.
 
Lub teeb ob chav tuaj yeem tau txais los ntawm ob lub lasers ywj pheej lossis los ntawm kev faib lub teeb nrog lub teeb splitter.
 
Ob lub teeb tuaj yeem yog kev sib xyaw ua ke ntawm cov lasers nrog cov yam ntxwv sib txawv ntawm lub sijhawm (pulsed vs. continuous), cov wavelengths sib txawv (mid-infrared vs. visible wavelengths) thiab lub zog sib txawv, uas tuaj yeem xaiv raws li cov khoom siv ua tiav tiag tiag.

4. Kev Siv Laser Composite Vuam
Vim yog siv lub teeb laser ua qhov chaw cua sov nkaus xwb, ib qho chaw cua sov laser vuam muaj qhov hloov pauv hluav taws xob tsawg thiab tus nqi siv, qhov chaw sib txuas ntawm cov khoom siv weld yooj yim los tsim cov misalignment, yooj yim los tsim cov qhov hws thiab cov kab nrib pleb thiab lwm yam tsis zoo, txhawm rau daws qhov teeb meem no, koj tuaj yeem siv cov yam ntxwv cua sov ntawm lwm qhov chaw cua sov los txhim kho qhov cua sov ntawm lub laser ntawm qhov workpiece, feem ntau hu ua laser composite welding.
 
Daim ntawv tseem ceeb ntawm laser composite welding yog kev sib xyaw ua ke ntawm laser thiab hluav taws xob arc, 1 + 1 > 2 cov nyhuv yog raws li nram no.
 
tom qab lub teeb laser ze ntawm qhov arc siv,qhov ceev ntawm cov electron raug txo qis heev, cov plasma huab uas tsim los ntawm laser vuam yog diluted, uastuaj yeem ua rau lub laser nqus tau zoo dua qub, thaum lub arc ntawm lub hauv paus khoom preheating yuav ntxiv nce qhov nqus ntawm lub laser.
 
2. kev siv zog siab ntawm lub arc thiab tag nrhokev siv zog yuav nce ntxiv.
 
3, thaj chaw ua haujlwm ntawm laser welding yog me me, yooj yim ua rau tsis sib haum ntawm qhov chaw vuam, thaum lub zog thermal ntawm arc loj, uas tuaj yeem ua tautxo qhov tsis sib haum ntawm qhov chaw vuam. Tib lub sijhawm, tusqhov zoo thiab kev ua haujlwm ntawm lub arc vuam tau zoo duavim yog qhov kev tsom mus rau thiab kev coj ua ntawm lub teeb laser rau ntawm lub arc.
 
4, laser vuam nrog qhov kub siab tshaj plaws, thaj chaw kub loj, txias sai thiab khov sai, yooj yim tsim cov kab nrib pleb thiab qhov hws; thaum thaj chaw kub ntawm arc me me, uas tuaj yeem txo qhov kub thiab txias, txias, khov sai,tuaj yeem txo thiab tshem tawm qhov tsim ntawm cov qhov hws thiab cov kab nrib pleb.
 
Muaj ob hom kev vuam laser-arc composite: laser-TIG composite welding (raws li qhia hauv qab no) thiab laser-MIG composite welding.

Tseem muaj lwm hom kev vuam xws li laser thiab plasma arc, laser thiab inductive heat source compound welding.
