Nrog kev nce qib ntawm kev siv tshuab hauv tshuab hluav taws xob, tsheb, tsheb nqaj hlau, tubrog nkoj, aerospace thiab lwm yam kev lag luam, laser vuam tshuab tau thov ntau thiab ntau dua. Cov cuab yeej siv laser lub tshuab txuas kuj tseem yuav tsim kom muaj ntau qhov qauv, siv tau ntau lub zog.
Tam sim no, muaj peb hom lasers siv hauv khw: fiber ntau, pulsed Nd: YAG thiab CO2 lub hauv paus laser. Peb hom khoom siv welder tau txais chav txaus tsim kho thiab tau rov siv dua rau hauv cov tshuab ua haujlwm siab. Tab sis qee cov ntawv thov tsis zoo li qhov no, xws li ultra-nyias cov ntaub ntawv.
Lub vuam ntawm ultra-nyias cov ntaub ntawv yog ultra-zoo technical kev ua haujlwm, uas yuav tsum muaj qhov siab xav tau rau cov kab teeb laser: lub zog lub zog, me me deformation thiab yooj ntawm vuam, txwv tsis pub nws yuav ua rau virtual vuam lossis hlawv-dhau. Thiab cov zoo no, fiber ntau lasers muaj.
Cov chaw ntawm cov kab hluavtaws laser tom qab tsom pom muaj tsawg li 10 microns, yog li cov leeg pob qij txha me me heev. Thiab vim tias nws yog qhov txuas nthwv dej laser, nws ua tau raws li lub zog siab yuav tsum tau siv rau pob thiab txuas mus txuas ntxiv. Hauv tshav dav hlau aerospace uas muaj qhov yuav tsum tau rau lub teeb yuag, fiber ntau laser vuam ntawm cov ntaub ntawv nyias rau cov khoom siv nyias muaj ntau qhov zoo dua thiab tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb hauv kev lag luam aviation. Nrog rau kev paub tab ntawm cov haujlwm thiab cov thev naus laus zis, fiber ntau lasers yuav dhau los ua ntau dua thiab siv dav hauv cov ntawv thov soldering.
Cua txias yuav tsum rau fiber ntau laser welded nplooj ntawv
Tsis txhob saib ntawm kev ua zoo ntawm hom fiber ntau. Qhov tseeb, nws tsis yog "yoog" thiab yog tswj zoo. Tsuav nws tau ua haujlwm zoo thiab siv tau, nws lub neej ua haujlwm ntev. Ntawm lawv, kev xaiv ntawm laser chiller yog tus yuam sij. Ua ntej, lub tshuab ua hluav taws xob laser yuav tsum muaj lub zog txias txaus thiab tom qab ntawd ruaj khov. Tsis tas li ntawd, cov dej tsis zoo kuj tseem yuav cuam tshuam rau lub laser (yeem ion lim kua).
