Laser Vuam thiab Electron Beam Vuam: "High-Tech" rau High-End Manufacturing

Nyob rau hauv high-end teb xws li aerospace thiab microelectronics, tsoos fusion vuam yog nyuaj rau ua tau raws li qhov yuav tsum tau ntawm precision thiab tob tob. Laser vuam thiab electron beam vuam sawv tawm nrog lawv qhov zoo ntawm "siab zog ceev, siab precision, thiab tsawg deformation."

Laser vuam:Nws siv lub zog loj laser beam (wavelength 1064nm lossis 10.6μm) tsom rau ntawm qhov chaw ua haujlwm. Qhov ntsuas kub tam sim no tuaj yeem ncav cuag tshaj 10,000 ° C, paub txog kev yaj sai sai thiab koom nrog cov hlau. Nws nta nqaim welds thiab me me tshav kub-tshem cov cheeb tsam, ua rau nws haum rau vuam nyias-walled Cheebtsam thiab micro-qhov chaw, xws li smartphone koob yees duab brackets thiab aero-engine hniav.

Electron Beam Vuam:Nyob rau hauv ib puag ncig lub tshuab nqus tsev, lub teeb hluav taws xob tau nrawm dua thiab tsom mus rau foob pob ua haujlwm. Nrog lub zog ceev kom siab li 10^6-10^8 W / cm², nws tuaj yeem ua tiav qhov sib sib zog nqus nqus vuam nrog qhov sib piv txog li 10: 1. Nws yog tsim rau tuab-walled precision Cheebtsam xws li nuclear reactor qhov chaw thiab lub zog loj. Txawm li cas los xij, nws muaj cov cuab yeej siv siab thiab xav tau ib puag ncig lub tshuab nqus tsev, ua rau muaj kev txwv tsis pub siv cov xwm txheej.

Cov khoom sib xyaw & Laser hom

Ib tug txheej txheem laser welding system muaj peb yam tseem ceeb:

Laser Generator: Hloov hluav taws xob hluav taws xob mus rau hauv lub teeb laser coherent.

Optical Transmission System: Qhia thiab tsom rau cov nqaj (piv txwv li, fiber ntau optics, tsom iav).

Workstation: Integrated fixtures, motion controls (robots/linear stages), thiab kev tiv thaiv roj xa.

Cov txheej txheem tseem ceeb Parameter & Cov Txheej Txheem Kev Ua Haujlwm

Parameter tswj ncaj qha txiav txim siab qhov zoo ntawm vuam-txawm tias qhov sib txawv me me tuaj yeem ua rau muaj qhov tsis xws li porosity lossis tawg:

(1) Kev npaj ua ntej vuam

Kev Tu Cov Khoom Siv: Tshem cov roj, cov nplais oxide, lossis cov txheej txheem siv ethanol lossis sandblasting. Rau cov khoom siv hluav taws xob siab (Al, Cu), ua ntej kho qhov chaw kom txo cov kev cuam tshuam laser.

Focal Positioning: Siv qhov tsis zoo defocus (tseem ceeb hauv qab ntawm qhov chaw ua haujlwm) rau kev nkag mus tob; zoo defocus (focus saum toj no) rau nyias cov ntawv kom tsis txhob hlawv-los ntawm.

Daim Ntawv Thov Kev Lag Luam & Case Studies

Laser welding's versatility drives innovation nyob rau hauv cov sectors:

(1) Kev tsim kho & Kev lag luam hnyav

Steel Structures: Ob chav taub hau laser-arc hybrid vuam tshuab vuam 20mm + T-beams ntawm 1.2m / min, txo deformation los ntawm 50%.

Shipbuilding: Robot-guided systems with 7th-axis rails weld 115mm-thick hull plates in single passes, daws qhov "sib-sab vuam, ob-sab tsim" kev sib tw.

(2) Automotive Manufacturing

Precision vuam ntawm cov khoom sib kis siv "keyhole stability control technology" kom ua tiav qhov tsis xws luag-dawb ncig welds.

Laser tailor-welding ntawm lub tsheb lub cev panels txo ib feem suav los ntawm 30% thiab hnyav los ntawm 15%.

(3) Advanced Zog & Aerospace

Nuclear Zog: Fiber laser vuam ntawm Ni-28W-6Cr alloy (rau 850 ° C molten ntsev reactors) nrog tawg ntho ntawm parameter optimization.

Aerospace: Vuam ntawm titanium alloy cav hniav nrog tsawg heev tshav kub-tshem tawm tsam (HAZ) kom khaws cov khoom siv zog.
