Laser vuam muaj qhov zoo ntawm lub zog siab ceev, vuam me me deformation, me me tshav kub-tshem tawm tsam, thiab vuam loj nkag mus, thiab tau dav siv nyob rau hauv lub teb ntawm precision vuam ntau lawm. Nyob rau hauv xyoo tas los no, kev tshawb fawb ntawm titanium alloy laser welding tau txais ntau thiab ntau dua los ntawm ntau lub teb chaws, thiab ntau yam kev tshawb fawb tau ua tiav. Qhov tsab xov xwm no yuav tsom mus rau cov yam ntxwv ntawm titanium alloy nyias phaj laser vuam, tuab phaj laser vuam, laser hybrid vuam, nquag laser vuam, laser vuam ntawm cov khoom sib txawv, thiab lwm yam.
1. Laser vuam ntawm titanium alloy nplooj ntawv
Titanium alloys siv nyob rau hauv aerospace teb feem ntau yog nyias daim hlau nrog ib tug tuab ntawm 1 mus rau 2 hli. Yog li ntawd, ntau tus kws tshawb fawb tam sim no kev tshawb fawb ntawm laser vuam ntawm titanium alloy nyias daim hlau tsuas yog tsom rau kev kub ceev vuam ntawm daim hlau nrog lub thickness ntawm 1 mus rau 2 hli. Thaum ua tau raws li cov txheej txheem ntawm vuam ib leeg thiab ob sab sib sau, qhov siab tshaj plaws vuam ceev tuaj yeem ncav cuag 3.6m / min. Feem ntau ntawm cov ntaub ntawv hauv paus tsom rau hauv kev tshawb fawb yog TC4 titanium alloys, thiab lub hom phiaj ntawm kev tshawb fawb yog nyob ntawm qhov cuam tshuam ntawm ntau yam txheej txheem vuam (xws li lub zog laser, vuam ceev, defocus, thiab lwm yam) ntawm kev tsim cov vuam thiab cov khoom siv. . Rau 0.5 hli tuab phaj, kev cuam tshuam ntawm ntau yam txheej txheem tsis nyob rau hauv vuam seam tsim tau kawm. Qhov loj ntawm cov txheej txheem qhov rais nyob rau hauv cov xwm txheej ntawm nyias phaj qis-ceev vuam (vuam ceev: 1.5m / min) thiab nyias phaj siab ceev vuam (vuam ceev: 3m / min) yog piv. Cov txiaj ntsig tau pom tias cov txheej txheem qhov rais ntawm nyias phaj high-speed vuam yog loj dua, ua rau vuam seam ntau tsim. Yooj yim tswj.
2. Laser vuam ntawm titanium alloy nruab nrab thiab tuab daim hlau
Medium-tick titanium alloy daim hlau yog dav siv nyob rau hauv petrochemical thiab shipbuilding industries. Rau kev vuam ntawm titanium alloy nruab nrab thiab tuab daim hlau, TIG vuam thiab electron beam vuam yog tam sim no txoj kev tseem ceeb. Kev tshawb fawb hauv tsev thiab txawv teb chaws ntawm laser vuam ntawm nruab nrab-tuab titanium alloy daim hlau tseem nyob rau theem tsis paub qab hau. Cov khoom siv hauv paus tsom rau hauv kev tshawb fawb yog TC4, thiab lub thickness ntawm daim hlau feem ntau yog qis dua 10 hli. Thaum lub sij hawm kev tshawb fawb txheej txheem, nws tau pom tias nruab nrab-tuab titanium alloy daim hlau Thaum lub sij hawm laser vuam, muaj cov teeb meem tseem ceeb xws li plume, nto oxidation, pores, thiab cov kab nrib pleb uas yuav tsum tau kho sai sai.
3. Titanium alloy laser hybrid vuam
Tungsten arc vuam (TIG vuam luv luv) yog ib txoj kev vuam zoo nrog qhov zoo ntawm cov txheej txheem vuam ruaj khov thiab tsis tshua muaj vuam sib dhos. Txawm li cas los xij, nws kuj raug kev txom nyem los ntawm arc zog divergence, tsis muaj zog arc nkag mus, thiab ntiav welding nkag mus. ua tsis tau. Laser welding muaj qhov zoo ntawm qhov muaj peev xwm nkag mus tau zoo, tab sis nws muaj kev sib dhos siab.
