Nrog nce precision thiab zoo yuav tsum tau nyob rau hauv manufacturing, automotive, electronics, biomedical, thiab hmoov metallurgy industries, tsoos koom txoj kev yog sai tau hloov los ntawm high -precision laser vuam tshuab.
Thaum ntsuas cov khoom siv laser vuam, kev nkag siab txog cov txheej txheem tseem ceeb yog qhov tseem ceeb rau kev xaiv txoj cai rau koj daim ntawv thov tshwj xeeb. Hauv qab no yog cov kev ntsuas kev ua haujlwm tseem ceeb uas koj yuav tsum tsom mus rau thaum lub sijhawm yuav khoom.
Laser Pulse Zog
Laser Pulse Zog yog hais txog lub siab tshaj plaws tso zis zog xa los ntawm ib tug mem tes, ntsuas hauv Joules (J).
- Kev cuam tshuam tseem ceeb:Pulse zog txiav txim siab qhov ua tau zoo tshaj plaws thiab qhov tob tob ntawm lub laser.
- Xaiv Tswv Yim:Ntawm qhov nruab nrab lub zog tsis tu ncua, siab dua ib zaug -pulse zog feem ntau ua rau qis dua qhov siab tshaj plaws mem tes. Nws yog ib qho tseem ceeb kom phim lub zog mem tes rau cov khoom thickness thiab thermal rhiab heev ntawm koj daim ntawv thov.
Focal Spot Diameter & Optical Precision
The Focal Spot Diameter (measured in mm) directly dictates the laser's power density and effective heat-affected zone.
- Vim Li Cas Nws Tseem Ceeb:High -zoo optical designs compress laser zog rau hauv ib tug meej focal point (feem ntau ntawm 0.2 mm thiab 1.5 mm). Kev tswj qhov chaw focal mus txog 0.2 hli los yog me dua yuav tsum muaj cov khoom siv kho qhov muag thiab kev sib raug zoo.
- Common Pitfalls:Tsawg- nqi laser tshuab nrog subpar optical tsim feem ntau tsis ua kom pom tseeb. Qhov ntau qhov chaw loj heev ua rau thermal hlawv, seam widening, thiab deg ablation, uas tuaj yeem ua rau puas tsuaj rau qhov chaw lossis pwm.
Pulse Frequency (Repetition Rate)
Pulse zaus( ntsuas hauv Hertz, Hz) qhia txog pes tsawg lub laser pulses raug tso tawm ib ob.
- Kev cuam tshuam tseem ceeb:Zaus ncaj qha cuam tshuam rau kev ua haujlwm ceev thiab cov khoom siv cua sov hauv ib cheeb tsam. Thaum tag nrho lub zog laser raug kho, qhov rov ua dua siab dua faib lub zog rau hauv cov pulses me me.
- Xaiv Tswv Yim:Rau kev kho pwm precision lossis micro- vuam, kho cov mem tes zaus (piv txwv li, 1-100 Hz) tso cai rau kev tswj xyuas zoo tshaj qhov vuam zoo nkauj, seam flatness, thiab sib koom ua ke lub zog- xyuas kom du, porosity- dawb welds uas sib npaug lossis tshaj lub hauv paus hlau hauv cov khoom siv tshuab.
Waveform Shaping & Kaw -Loop Power Feedback
Xaiv qhov raug Laser Fais fab Waveform thiab tswj mechanism yog qhov tseem ceeb rau txoj kev sib txuas ntawm metallurgical:
- Pulse Width vs. Peak Power:Qhov dav pulse dav nce qhov dav ntawm lub pas dej ua ke, thaum lub zog siab dua siab tshaj tawm qhov tob tob.
- Tiag -Lub sij hawm tawm tswv yim:Cov txheej txheem siab tshaj siv tiag tiag - lub sij hawm lub hwj chim tawm tswv yim tswj kom tswj tau cov mem tes - rau - mem tes sib xws, txo cov kev hloov pauv ntawm lub zog thiab ua kom muaj kev sib txuam ntawm weld seam zoo thoob plaws kev ua haujlwm tas mus li.
Tus neeg yuav khoom pom zoo Summary
Txhawm rau pab koj ntsuas cov kev qhia tshwj xeeb no thaum koj xaiv cov txheej txheem, cov ntsiab lus tseem ceeb hauv qab no sib tw rau txhua qhov kev ntsuas ncaj qha rau nws qhov kev siv vuam cuam tshuam:
| Parameter | Cov nyhuv tseem ceeb | Kev txiav txim siab thov |
| Pulse Zog (J) | Qhov tob tob & ib zaug - taw tes melting | Cov ntaub ntawv tuab dua yuav tsum muaj zog pulse ntau dua |
| Txoj kab uas hla (mm) | Lub zog ceev & cua sov- thaj tsam cuam tshuam | Cov me me (0.2 hli) tiv thaiv cov khoom ablation |
| Pulse zaus (Hz) | Vuam ceev & cua sov faib | High zaus rau du, nruam cosmetic seams |
| Waveform & Tawm tswv yim | Weld profile & txheej txheem stability | Ua kom muaj kev sib koom ua ke ntawm lub zog ntawm cov hlau reflective |
Thaum xaiv iblaser vuam tshuab, xyuas kom cov chaw tsim khoom muab cov peev xwm hloov kho qhov tseeb, cov kab hluav taws xob zoo, thiab muaj zog kaw - voj tswj kom phim koj cov kev xav tau tshwj xeeb.
