Titanium Alloy Laser Kho Vuam: Tshuab thiab kev siv

Taw qhia

Titanium alloys sib xyaw ua ke muaj zog tshwj xeeb thiab kev tiv thaiv corrosion, uas ua rau lawv kim heev los tsim thiab tsim nyog kho thaum lawv puas. Cheebtsam xws li aero- cav hniav, casings, pwm, thiab shafts tuaj yeem tsim cov kab nrib pleb, hnav, lossis qhov loj me hauv kev pabcuam. Laser kho vuam tau dhau los ua thev naus laus zis zoo tshaj plaws rau cov khoom no vim tias nws xa cov cua sov siab, cov cua sov me me- cuam tshuam thaj chaw, thiab kev tswj xyuas meej ntawm cov khoom tso cia, rov ua kom cov khoom tsis sib haum xeeb dua li cov pa vuam.

Yuav Ua Li Cas Laser Kho Vuam Ua Haujlwm

Laser kho vuam siv lub tsom teeb laser, feem ntau yog fiber ntau lossis diode laser, kom yaj qhov chaw ntawm qhov chaw puas thaum muab tub lim hlau los yog cov hmoov txhuas yog pub rau hauv lub pas dej. Nyob rau hauv lub keyhole tsoom fwv lub beam vaporizes ib channel nyob rau hauv cov khoom, ua kom tob, nqaim nkag; nyob rau hauv conduction hom lub pas dej ua ke yog ntiav thiab dav. Rau kev txhim kho kev ua haujlwm, cov kev txwv raug xaiv kom haum rau qhov xav tau qhov tob thiab qhov geometry ntawm qhov tsis xws luag. Vim hais tias lub beam yog precisely positioned thiab lub zog yog xa nyob rau hauv ib feem ntawm ib tug thib ob, lub tshav kub input ib chav tsev ntev yog deb tshaj li nrog arc txheej txheem, thiab cov khoom nyob ib puag ncig nyob ze rau ambient kub.

Vim li cas Shielding yog qhov tseem ceeb rau Titanium

Titanium yog chemically txhoj puab heev tshaj li 250 degree: nws absorbs oxygen, nitrogen, thiab hydrogen, uas harden thiab embrittle cheeb tsam weld. Cov kab mob kis tau tshwm sim raws li kev hloov xim, los ntawm nyiaj mus rau straw, xiav, grey, thiab thaum kawg hmoov dawb. Laser kho vuam yuav tsum yog li ntawd yuav tsum tau ua nyob rau hauv inert gas shielding, feem ntau argon los yog helium, npog tsis tau tsuas yog lub yaj pas dej ua ke tab sis tag nrho cov cua sov cheeb tsam kom txog rau thaum cov hlau txias hauv qab no 250 degree. Trailing shields thiab purge chambers yog cov qauv kev coj ua, thiab cov xim ntawm cov xim tom qab txias yog qhov qhia tau zoo.

Laser Cladding: Txhim kho cov tawv nqaij

Rau kev hnav thiab corrosion puas, laser cladding deposits alloy hmoov txheej los ntawm txheej los txhim kho qhov qub qhov ntev. Hmoov yog txhaj rau hauv lub pas dej ua ke los ntawm lub coaxial nozzle, thiab lub teeb txav mus rau saum npoo, tsim kom muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Dilution nrog lub substrate yog tswj los ntawm ob peb feem pua, uas khaws cov khoom ntawm qhov tso nyiaj. Laser cladding tuaj yeem tsim kho cov kabmob, cov lus qhia hniav, thiab cov av sib khi ntawm cov khoom siv titanium, thiab cov khoom siv tib yam tuaj yeem ntxiv hnav- tiv taus cladding rau qhov tshiab rau kev pab cuam lub neej ntev.

Qhov zoo tshaj li Kev Kho Kho Vuam

Tsawg cua sov input thiab distortion:nyias-phab ntsa thiab cov geometries complex nyob rau hauv kam rau siab tom qab kho.

Cov cua sov me me- thaj tsam cuam tshuam:hauv paus-cov khoom hlau yog khaws cia ze rau qhov vuam.

Precision:Cov yam ntxwv me me thiab cov kab noj hniav sab hauv tuaj yeem siv tau nrog cov kab teeb pom kev zoo thiab xa cov fiber ntau.

Shorter cycles:automated parameter tswj txo cov teeb tsa- nce thiab rov ua dua piv nrog kev kho TIG.

Khoom siv kev lag luam:tsuas yog qhov chaw puas tsuaj tau tsim, txo qis kev siv cov khoom siv thiab tom qab-machining.

Cov txiaj ntsig zoo no ua rau kev kho laser kev lag luam rau siab - cov khoom muaj nqis xws li compressor blades, turbine disks, thiab cov khoom siv sib txuas, qhov twg cov nqi hloov pauv siab thiab lub sij hawm txhuas ntev.

Daim ntawv thov

Aerospace coj mus rau qhov chaw: cov hniav thiab blisks nrog lub ntsej muag coj los yog txawv teb chaws - khoom puas tsuaj, casings nrog cov kab nrib pleb, thiab cov khoom siv nrog machining defects raug kho thiab rov qab mus rau qhov kev pab cuam tom qab tsim nyog. Sab nraum aerospace, thev naus laus zis ua haujlwm pwm thiab tuag, twj tso kua mis thiab lub valve, cov khoom siv hauv hiav txwv, thiab cov khoom siv tshuaj lom neeg, qhov twg titanium alloys tau teev tseg rau kev xeb thiab cov khoom siv nyiaj ntau dhau los pov tseg. Kev kho ntawm qhov chaw uas tsis tuaj yeem welded los ntawm cov txheej txheem ib txwm siv, suav nrog cov kab noj hniav thiab cov ntu nyias, yog qhov loj hlob niche.

Kev Tswj Xyuas Zoo thiab Cov Qauv

Kho welds ntawm titanium yog tsim nyog zoo li cov welds ntau lawm. Cov txheej txheem thiab welder tsim nyog ua raws li cov qauv hauv aerospace xws li AWS D17.1 rau fusion vuam, thiab txhua qhov kho tau raug tshuaj xyuas los ntawm kev tshuaj ntsuam dye penetrant, kuaj ultrasonic, lossis radiography nyob ntawm chav kawm tsis raug. Cov kev kuaj hlau muaj xws li weld-zone hardness, microstructure, thiab porosity ntsuam xyuas, thiab tom qab- kho cua sov kho tej zaum yuav tsum tau los kho cov khoom hauv tshav kub- kho tau cov alloys. Dimensional checks paub meej tias ib feem raws li kos duab txwv tom qab machining zaum kawg. Kev kuaj xim xim tseem yog thawj - kab qhia ntawm kev tiv thaiv kev txaus.

Kev txwv thiab kev txiav txim siab

Kev kho laser xav tau cov cuab yeej peev, kev npaj ntog meej, thiab cov txheej txheem kev txawj ntse. Cov kev tsis xws luag yuav tsum tau muab tshem tawm tag nrho ua ntej tso, kev sib kis yuav tsum raug cais tawm ntawm txhua theem, thiab kev nkag mus rau thaj tsam puas tsuaj yuav tsum tso cai rau kev xa khoom thiab kev tiv thaiv. Rau qhov loj heev lossis ua tsis taus pa, tus nqi ntawm kev tuav yuav dhau qhov txiaj ntsig. Txhua txoj haujlwm kho yuav tsum raug ntsuas raws li tus nqi hloov pauv, kev tsim nyog, thiab muaj cov txheej txheem pom zoo.

Cov lus nug nquag

titanium puas tuaj yeem kho los ntawm laser vuam?

Yog lawm. Laser kho vuam yog tsim los xyaum rau titanium Cheebtsam, tshwj xeeb tshaj yog nyob rau hauv aerospace, thiab yog nyiam qhov uas tsis muaj cua sov input thiab precision yuav tsum tau.

Vim li cas kev tiv thaiv tseem ceeb heev thaum vuam titanium?

Dab tsi yog qhov txawv ntawm laser vuam thiab laser cladding?

Laser welding koom nrog los yog ua kom muaj qhov tsis xws luag nrog lub pas dej ua ke thiab muab tub lim; laser cladding deposits txheej txheej los yog rebuilds qhov ntev nrog alloy hmoov. Ob leeg siv tib chav kawm ntawm cov khoom siv thiab kev tiv thaiv zoo sib xws.

Puas yog kho laser muaj zog dua TIG kho rau titanium?

Tsis tas li, tab sis kho laser ua kom muaj kev cuam tshuam tsawg dua thiab cov cua sov me me- thaj chaw cuam tshuam, uas khaws cov hauv paus- cov khoom hlau zoo dua ntawm qhov nyias thiab qhov tseeb. Cov txheej txheem tsim nyog thiab kev tshuaj xyuas txiav txim siab qhov zoo kawg nkaus.

Qhov twg feem ntau yog laser- kho?

Aero- cav hniav thiab blisks, casings, pwm, shafts, twj tso kua mis Cheebtsam, thiab ib tug siab - nqi titanium ib feem nrog rau hauv zos hnav, tawg, los yog seem poob.

Cov qauv twg tswj hwm kev kho titanium vuam?

AWS D17.1 npog fusion vuam ntawm aerospace hardware; Cheebtsam- cov kev kho tshwj xeeb thiab NDT cov kev cai siv nyob ntawm tus neeg siv khoom thiab cov chav kawm.
