Nrog rau kev loj hlob tawg ntawm cov tsheb tshiab lub zog, kev nthuav dav ntawm cov roj teeb hluav taws xob ntau lawm tau tsav kev loj hlob ntawm laser vuam.Txij li thaum lub thib ob ib nrab ntawm 2018, handheld laser welding tau maj mam nce, thiab tau dhau los ua ib qho chaw ci ntsa iab hauv kev lag luam laser vuam hauv thawj ib nrab ntawm lub xyoo no.Nrog rau tam sim no technical theem thiab daim ntawv thov scenarios ntawmhandheld laser vuam, nws muaj peev xwm hloov cov tsoos TIG vuam tshuab (argon arc vuam) ua lag luam.

Nyob rau hauv xyoo tas los no,fiber ntau laserstau ua tiav zoo, thiab lawv cov txiaj ntsig feem ntau suav nrog: siab photoelectric hloov pauv tus nqi, ceev cov cua sov dissipation, zoo yoog raws, muaj zog tiv thaiv kev cuam tshuam muaj peev xwm, tsis tshua muaj nqi, lub neej ntev, hloov kho-dawb, txij nkawm-dawb, siab stability, me me, tes - tuav laser vuam khoom siv fiber ntau lasers kuj maj mam tsim.

Laser vuamyuav tsum muaj kev sib dhos siab precision ntawm lub workpiece, thiab weld seam yog qhov tsis xws luag.Txhawm rau daws qhov teeb meem no, tus tsim qauv hais txog cov khoom siv laser vuam ntawm lub dav hlau tshwj xeeb los tsim cov khoom siv tes tuav laser vuam nrog lub viav vias qhov chaw.Lub laser yog nyob rau hauv cov duab ntawm "8" los yog "0" hom viav vias tuaj yeem txo qhov kev sib dhos ntawm cov khoom ua haujlwm thiab ua kom cov vuam nkag mus. -1.5KW, thiab qhov loj thiab qhov hnyav ntawm cov khoom siv sib npaug rau argon arc vuam tshuab, uas tuaj yeem vuam hlau phaj ntawm 3 hli lossis tsawg dua. Cov chaw tsim khoom tau koom ua ke tsis siv neeg hlau pub khoom siv los ntawm lub hauv paus ntawm laser welding, thiab tsim cov khoom siv tes tuav laser xaim-filling vuam cov cuab yeej uas tuaj yeem tau txais cov xov hlau, uas ua tau raws li qhov xav tau ntawm cov hlau nyias hauv qab 4m. argon arc vuam, paub kev kub ceev, tsis tshua muaj cua sov input, me me deformation, tsis tshua muaj nqi ib puag ncig tiv thaiv vuam, thiab cov nqi raug qis dua li ntawm argon arc vuam.nd rau tib yam mob.

Thaum ua hauj lwm, lub tes tuav lub taub hau ntawm lub vuam tshuab muaj ib tug scanning dav, thiab nws qhov chaw txoj kab uas hla yog me me, yog li thaum welding, nws scans los ntawm ib tug taw tes mus rau lwm qhov taw tes kab los ntawm kab, yog li tsim ib tug weld hlaws.Piv nrog rau cov txheej txheem txias txias, qhov vuam ceev ntawm tes tuav laser vuam yuav nrawm dua, thiab cov txheej txheem vuam ib zaug txiav txim siab tias nws yog qhov tsim nyog rau huab hwm coj vuam ntawm qhov ntev ncaj seams.

Thiab lub tes tuav laser vuam tshuab siv qhov chaw me me, thiab feem ntau yog nruab nrog ntau yam ntawm tes tuav taub hau.Raws li cov kev xav tau sib txawv ntawm cov khoom siv hlau xws li kev sib txuas sab nraud, vuam sab hauv, txoj cai-lub kaum vuam, nqaim ntug vuam, thiab qhov chaw loj vuam, qhov sib txawv ntawm tes vuam taub hau tuaj yeem xaiv.Cov khoom uas tuaj yeem welded muaj ntau haiv neeg, thiab cov khoom zoo li hloov tau yooj yim dua.Rau kev cob qhia ntau lawm koom nrog hauv kev ua haujlwm me me thiab tsis yog-loj vuam, cov khoom siv tes tuav laser vuam yog qhov kev xaiv zoo tshaj plaws.

Cov khoom siv hlau sib txawv muaj cov ntsiab lus sib txawv: qhov kev teeb tsa ntawm vuam tsis sib txawv ntawm cov khoom siv vuam sib txawv yog qhov nyuaj, thiab cov khoom siv thermophysical ntawm cov khoom siv vuam yuav qhia qhov sib txawv ntawm qhov kub thiab txias;qhov nqus ntawm cov khoom sib txawv ntawm cov khoom siv rau laser kuj yuav sib txawv nrog Qhov kub thiab txias hloov qhia qhov sib txawv;solder sib koom ua ke melting thiab cov txheej txheem evolution ntawm lub tshav kub-cuam tshuam cheeb tsam thaum lub sij hawm solidification ntawm weldment;kev sib koom ua ke ntawm lub tes tuav laser vuam tshuab, vuam kev koom tes kev ntxhov siab thiab thermal deformation, thiab lwm yam. Tab sis qhov tseem ceeb tshaj plaws yog qhov cuam tshuam ntawm qhov sib txawv ntawm cov khoom ntawm cov khoom siv vuam ntawm macro thiab micro zog ntawm vuam.

Cov ntaub ntawv twg tuaj yeem ua tautes tuav laser welding tshuabvuam?

1. Stainless hlau

Stainless hlau muaj ib tug siab coefficient ntawm thermal expansion, thiab nws yog nquag overheating thaum vuam.Thaum tshav kub-tshuaj tiv thaiv yog me ntsis loj, nws yuav ua rau muaj teeb meem loj deformation.Txawm li cas los xij, cov cua sov tsim los ntawm lub tshuab nqa laser vuam thaum lub sij hawm tag nrho cov txheej txheem vuam yog tsawg.Ua ke nrog cov thermal conductivity tsawg, siab zog nqus tus nqi thiab melting efficiency ntawm stainless hlau, zoo tsim, du thiab zoo nkauj welds tuaj yeem tau tom qab vuam.

2. Carbon hlau

Cov pa roj carbon zoo tib yam tuaj yeem raug welded ncaj qha los ntawm tes tuav laser vuam, cov nyhuv yog piv rau stainless hlau vuam, thiab qhov kub-cuam tshuam cheeb tsam me me, tab sis thaum vuam nruab nrab thiab siab carbon steel, qhov seem kub yog qhov siab, yog li nws tseem yuav tsum tau vuam ua ntej vuam.Preheating thiab kub preservation tom qab vuam kom txo tau kev ntxhov siab thiab tsis txhob tawg.Ntawm no peb tuaj yeem tham txog lub tshuab welding txias.Nruab nrab thiab siab carbon steel tuaj yeem welded lossis kho ntawm qhov qeeb qeeb nrog cov vuam txias thiab cam khwb cia hlau vuam hlau.Nyob rau hauv cov nqe lus ntawm kev tswj qhov kub thiab txias, tswj qhov kub thiab txias, lub tshuab txias welding tuaj yeem qhia kev tuav tes laser welding ntau npaum li cas ntawm cov khoom cua sov tom qab vuam.

3. Tuag hlau

Nws yog tsim rau vuam ntau hom hlau tuag, thiab cov nyhuv vuam zoo heev.

4. Aluminium thiab aluminium alloy

Aluminium thiab aluminium alloys yog cov ntaub ntawv zoo heev, thiab porosity yuav tshwm sim hauv lub pas dej ua ke los yog hauv paus thaum lub sij hawm vuam.Piv nrog rau yav dhau los cov ntaub ntawv hlau, txhuas thiab txhuas alloys muaj ntau dua qhov yuav tsum tau rau cov tsis, tab sis ntev li ntev raws li cov kev xaiv welding tsis tsim nyog, weld seam nrog tib yam txhua yam khoom raws li lub hauv paus hlau yuav tau.

5. Copper thiab tooj liab alloy

Lub thermal conductivity ntawm tooj liab muaj zog heev, thiab nws yog ib qho yooj yim los ua kom tiav kev nkag mus thiab ib nrab fusion thaum vuam.Feem ntau, cov khoom siv tooj liab yog rhuab thaum lub sij hawm vuam txheej txheem los pab vuam.Ntawm no peb tab tom tham txog cov khoom siv tooj liab nyias.Tes tuav laser vuam tuaj yeem ncaj qha Vuam, vim tias nws lub zog muaj zog thiab vuam ceev ceev, tsis tshua muaj kev cuam tshuam los ntawm cov thermal conductivity ntawm tooj liab.

6. Vuam ntawm cov khoom sib txawv

Lub tes tuav laser vuam tshuab tuaj yeem nqa tawm ntawm ntau yam hlau tsis sib xws, xws li tooj liab-nickel, nickel-titanium, tooj liab-titanium, titanium-molybdenum, tooj dag-tooj ​​liab, qis carbon steel-tooj ​​liab thiab lwm yam hlau tsis sib xws.Laser welding tuaj yeem ua tau raws li txhua yam kev mob (gas lossis kub).
