CEEV FAWPS THIAB COV DAIM NTAWV NTAWM LASER VUAM TSHUAB rau Aluminium Cov Khoom Siv Vuam
{{0 {} kev sib tw tseem ceeb hauv Aluminium Laser Vuam
Txhuas vuam vuam nrog lasers ntsej muag peb thawj cov teeb meem:
High Reflectivity: Aluminum reflects >90% ntawm cov ntug lasers ze-infrared (1μm wavelength), drastically txo lub zog nqus nqus nqus lub zog.
Tsawg BLATE taw tes & siab thermal conductivity: nrog lub boiling taw tes ntawm 2467 degree), ua rau cov neeg thermal tau yooj yim (237)
Oxide txheej thiab porosity: txheej txheej al₂o₃ oxide txheej (thaum hydrogen solubility sib txawv ntawm cov kua thiab tawv rau porosity thaum sandosation.

Laser Qhov Chaw Xaiv
Blue Lasers (450nm): Ideal for thin sheets (0.2–3mm), offering >60% nqus .
High-Power Fiber Lasers (1μm): Suitable for medium-thickness plates (3–8mm) with peak power >6kW to suppress Reflection Instability .
Ntsuab lasers (532nm): Siv tau zoo rau high-refendity alloys (e {}}}}}} {.
Nco tseg: xiav / ntsuab lasers muaj siab dua cov nqi; Smes tuaj yeem xaiv rau cov xaim xaim lasers nrog saum npoo pretreatment .
Cov txheej txheem tseem ceeb
Kev Tswj Xyuas Fais Fab: Siv 1-3kw pulsed hom rau cov ntawv nyias nyias kom tiv thaiv kev hlawv-los ntawm; thov ntau dua lossis sib npaug rau 4kW tas luav yoj tes nrog cov nqaj hlau (e}} g}
Mem tes shaping: Square-yoj pulses nrog qeeb txoj kev sib tw ua ntej sol-olide txheej ua ntej melting .
Kev thaiv cov roj: Helium-messtures (ntau dua los yog sib npaug rau 70 l / min Flowle Benpogen {}} txoj hauj lwm nozzles<5mm from the workpiece.
Nto Pretreatment
Mechanical Cleaning: Scrub with stainless steel wire brushes followed by acetone wiping to remove oxides, boosting absorption by >30%.
Tshuaj lom neeg: Riam rau hauv 10% NOOH rau 2 feeb, yaug nrog dej, tom qab ntawd passivate nrog nitric acid kom yaj al₂o₃.
Absos tsho tiv no: siv cov pa roj teeb dub lossis tshuaj phosphate (<10μm thick) to enhance initial energy coupling.
3. Cov Lus Qhia Zoo
Porosity Mitigation
Txo kev mus ncig ua si nrawm hauv qab 3m / min los txuas ntxiv cov pas dej ua ke nyob hauv hydrogen khiav tawm .
Qaij lub laser nqaj 15℃-20℃kom txo vapor recoil siab.
Siv post-weld kev kho cua sov (150-200℃rau 2 teev) kom diffuse cuab ntxaij .
TIAV NYEEM
Siv cov xaim hluav taws xob qis
Txwv tsis pub cua sov tawm mus rau tsawg dua lossis sib npaug rau 80 j / hli kom tsis txhob ua qoob loo ntxhib.
Kev tshuaj xyuas lub sijhawm tiag tiag
Lub Voj Muag Lub Tshuab Pom Kev Sib Nraus
Ntshav Sensors ntes Ntes Keyhole Insability, nrhiav kev them nyiaj yog .
4.} Kev Lag Luam Kev Thov Cov Piv Txwv
Ev roj teeb allosures (6061 alloy, 2.5mm tuab):
Txheej Txheem: 4Kw Fiber Laser + Nws / Ar Roj Sib tov+ 0.8 mm-inch-diamas {}}
Qhov tshwm sim: 1.2: 1 qhov tob-rau-dav piv, porosity<0.5%, passes IP67 leak test.
Aerospace roj tso tsheb hlau luam (2219 almoy, 8mm tuab):
Txheej Txheem: 2Kw Xiav Laser + Dual-Pulse tshem tawm, lub mem tes tseem ceeb rau vuam).
Qhov tshwm sim: tensile lub zog ntau dua los yog sib npaug rau 85% ntawm lub hauv paus hlau, xoom kub tawg.
{{05. kev nyab xeeb thiab kho cov txheej txheem
Kev Nyab Xeeb: Cov neeg ua haujlwm yuav tsum hnav laser kev nyab xeeb goggles (od {} Kev ntaus ntawv yuav tsum tau reexic al₂o₃ particulates.
Txhua tus neeg ua haujlwm yuav tsum muaj qib 4 daim ntawv pov thawj kev nyab xeeb, uas tau npog cov ntsiab lus hauv qab no:
Kev twv ua ntej ntawm txhuas lub teeb txoj kev (kom tsis txhob raug mob los ntawm cov nqaj tsis ncaj qha)
Cov txheej txheem xwm txheej ceev
Kev Txij Nkawm: huv si lenses txhua hnub nrog ethanol thiab cov ntaub nplej pub dawb kom tiv thaiv txhuas
Kev Nyab Xeeb Roj: Helium Rank tso tsheb hlau luam yog nruab nrog oxygen concenors (tswb cav los ntawm asseflectes tshwm sim los ntawm cov kua qaub.
6. tawm cov thev naus laus zis
Hybrid Vuam: Laser-Mig Synergic Vuam Siv Mig Arcs kom tso cov ntsaws hlau, them nyiaj rau txhuas lub enrinkage {}}
Ai-Tsav Qhov Kev Zoo: Tshuab Kawm Kev Kawm Pas Dej Pas Dej Ua Ntej Cov Duab Liab Qab los soj ntsuam Porosity thiab Auto-Kho Cov Lus Tshaj Tawm {2}
Txo Nqi Them Nyiaj: Cov xiav Laser Laser Laser tam sim no tshaj 2kW nrog 40% qis tus nqi, kev nkag siab me ntsis.
