Laser vuam: hauv paus ntsiab lus ntawm kev txiav txim thiab cov kev pab

Koom co muaj peev xwm yuav txawv. Qhov tseem txhim khu kev qha txoj kev uas yuav muab tau ib tug hnyav thiab tas mus li kev sib txuas ntawm txawv cov khoom yog laser welding. Nrog rau qhov no technology nws yog ua tau tsis tsuas mus cuag siab precision thiab cov neeg, tab sis kuj yuav muab cov ntaub ntawv muaj ib tug siab melting point los yog siab warmwater. Luv, tswj melting lub sij hawm thiab ib tug me me npaum li cas ntawm qhuav twb tso cai rau weld txawm tias cov neeg qhov chaw uas cov pa txoj kev tsis haum.

technology nta

Laser vuam yog yus nyob rau hauv uas lub laser beam muab ib tug high concentration ntawm lub zog ntawm tus taw tes uas txoj kab uas hla tsis pub tshaj ib tug ob peb micrometers. Lub hwj chim theem nce mus txog 10 ~ 8 W / cm2, uas yog ntev npaum li cas tshaj nws, piv txwv li, ib tug arc. Zog concentration ntawm laser vuam yuav muab piv xwb los hais tias ntawm lub electron nqaj (nws muaj peev xwm yog hais txog 10 ^ ib tug b W / cm2). Tab sis yog hais tias tus tom kawg yuav tau tsuas yog siv nyob rau hauv ib lub tshuab nqus chamber, lub laser vuam tej zaum yuav nqa tawm nrog rau tej kev inert roj puag ncig (CO _2, Nws, Ar) los yog tsuas yog cua. Nyob rau hauv cov nqe lus ntawm kev tswj, nws yog nqa tawm los ntawm ib tug optical system. Laser vuam yog ua nyob rau hauv ib tug ncaj ntau yam ntawm tej yam kev mob, thiab qhov no muaj ib tug high-kev ua tau zoo txheej txheem ntawm txuas tag nrho cov hom ntawm cov khoom, lub thickness ntawm cov uas pib los ntawm ib tug ob peb micrometers thiab mus txog rau ob peb kaum tawm ntawm millimeters. Txawm tias muaj tseeb hais tias tus txheej txheem no yog heev tham thiab twb tsis muaj universal theoretical qauv uas yuav piav txog nws nyob rau hauv tag nrho cov fullness, nws yog siv lug nyob rau hauv kev xyaum, thiab hais tias yog ib tug zoo yog vim li cas.

Qhov zoo laser vuam ntawm co

Ntawm cov undoubted zoo ntawm cov qauv no muaj xws li cov nram qab no:

1. High kev kawm ntawm no technology raws li muab piv nrog lwm txoj kev.
2. Me cheeb tsam ntawm thermal teebmeem, uas yog tsuas yog siv rau tsuas yog ib txoj kab uas hla ntawm laser. Qhov no tso cai rau koj mus tau lub feem ntau hauj zog thiab ductility ntawm kev twb kev txuas.
3. Tejzaum ntawm kev tswj thiab lub peev xwm los mus daws kev pab cuam kev hloov.
4. Tus phooj ywg environmentally. Niaj hnub nimno laser vuam installation eliminates qhov xav tau rau koom haum pab vuam ntaub ntawv thiab fluxes.
5. Muaj peev xwm zoo pub ntxiv tshaj txawv hlau.
6. Nws yog feem ntau yuav ua tau kom tsis txhob muaj cov kev siv ntawm muab tub lim cov ntaub ntawv.
7. Muaj peev xwm Vuam nyob rau hauv tsis yooj yim rau kev nkag tau mus qhov chaw.

Vuam ntawm hlau qhov chaw siv roj thiab khoom hauv lub xeev lasers li tus nruam thiab periodic tswv yim. Daim ntawv thov ntawm no technology yog ncaj qha nyob rau lub hwj chim chaw. Piv txwv li, lasers, uas nws lub hwj chim yog nyob rau hauv lub chav 100-500 W, tau ntev tau siv rau welding ntawm me me-sized Cheebtsam, xws li hluav taws xob Cheebtsam lossis kev kho mob kiag li lawm. Ib tsob nroj uas muaj peev xwm ntawm ywm ib tug ntau dua lub zog theem (nyob rau hauv kilomatt ntau) feem ntau siv nrog robots thiab fiber optics. Lawv yog cov zoo indispensable nyob rau hauv lub tsheb lag luam, mechanical engineering, shipbuilding thiab lwm yam industries.
