01 Kev vuam siv laser-arc hybrid phaj tuab
Cov phaj tuab (tuab ≥ 20mm) vuam ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv loj hauv cov teb tseem ceeb xws li aerospace, navigation thiab shipbuilding, kev thauj mus los ntawm tsheb ciav hlau, thiab lwm yam. Cov khoom no feem ntau yog tus cwj pwm los ntawm qhov tuab loj, cov qauv sib koom ua ke nyuaj, thiab cov chaw pabcuam nyuaj. Qhov zoo ntawm kev vuam muaj kev cuam tshuam ncaj qha rau kev ua haujlwm thiab lub neej ntawm cov khoom siv. Vim yog qhov ceev ntawm kev vuam qeeb thiab cov teeb meem loj heev, txoj kev vuam roj tiv thaiv ib txwm ntsib cov teeb meem xws li kev ua haujlwm vuam qis, kev siv hluav taws xob ntau, thiab kev ntxhov siab ntau, ua rau nws nyuaj rau ua kom tau raws li qhov xav tau ntawm kev tsim khoom. Txawm li cas los xij, laser-arc hybrid vuam thev naus laus zis txawv ntawm cov thev naus laus zis vuam ib txwm muaj. Nws ua tiav ua ke cov txiaj ntsig ntawmlaser vuamthiab arc vuam, thiab muaj cov yam ntxwv ntawm qhov tob tob, qhov ceev vuam ceev, kev ua haujlwm siab thiab qhov zoo dua ntawm kev vuam, raws li pom hauv Daim Duab 1 Qhia. Yog li ntawd, cov thev naus laus zis no tau nyiam kev saib xyuas dav dav thiab tau pib siv rau hauv qee qhov chaw tseem ceeb.
Daim Duab 1 Lub Ntsiab Cai ntawm laser-arc hybrid welding
02 Kev tshawb fawb txog kev vuam laser-arc hybrid ntawm cov phaj tuab
Lub koom haum Norwegian Institute of Industrial Technology thiab Lule University of Technology hauv Sweden tau kawm txog kev sib xws ntawm cov pob qij txha sib xyaw ua ke hauv qab 15kW rau 45mm tuab micro-alloyed high-strength low-alloy steel. Osaka University thiab Egypt's Central Metallurgical Research Institute siv 20kW fiber laser los ua kev tshawb fawb txog cov txheej txheem vuam ib zaug ntawm cov phaj tuab (25mm), siv lub liner hauv qab los daws qhov teeb meem hauv qab hump. Lub tuam txhab Danish Force Technology siv ob lub 16 kW disk lasers hauv series los ua kev tshawb fawb txog kev vuam sib xyaw ntawm 40mm tuab hlau phaj ntawm 32 kW, qhia tias kev vuam laser-arc siab zog yuav tsum tau siv rau hauv kev vuam cua fais fab hauv hiav txwv, raws li pom hauv Daim Duab 2. Harbin Welding Co., Ltd. yog thawj zaug hauv lub tebchaws los tswj cov thev naus laus zis tseem ceeb thiab cov cuab yeej siv sib xyaw ua ke ntawm cov khoom siv laser-melting electrode arc hybrid heat source vuam. Nws yog thawj zaug los ua tiav kev siv cov khoom siv laser-dual-wire melting electrode arc hybrid vuam thiab cov khoom siv rau cov khoom siv siab hauv kuv lub tebchaws. kev tsim khoom.
Daim Duab 2. Daim duab qhia txog kev teeb tsa laser
Raws li qhov kev tshawb fawb tam sim no ntawm laser-arc hybrid welding ntawm cov phaj tuab hauv tsev thiab txawv teb chaws, nws tuaj yeem pom tias kev sib xyaw ua ke ntawm laser-arc hybrid welding txoj kev thiab qhov nqaim qhov sib txawv tuaj yeem ua tiav kev vuam ntawm cov phaj tuab. Thaum lub zog laser nce mus txog ntau dua 10,000 watts, nyob rau hauv qhov irradiation ntawm lub zog siab laser, tus cwj pwm vaporization ntawm cov khoom siv, cov txheej txheem sib cuam tshuam ntawm laser thiab plasma, lub xeev ruaj khov ntawm cov dej ntws molten, lub tshuab hloov pauv cua sov, thiab tus cwj pwm metallurgical ntawm qhov vuam Kev hloov pauv yuav tshwm sim rau ntau qib. Thaum lub zog nce mus txog ntau dua 10,000 watts, qhov nce ntawm lub zog ceev yuav ua rau qib ntawm vaporization hauv thaj chaw ze ntawm lub qhov me me, thiab lub zog recoil yuav ncaj qha cuam tshuam rau qhov ruaj khov ntawm lub qhov me me thiab cov dej ntws ntawm lub pas dej molten, yog li cuam tshuam rau cov txheej txheem vuam. Cov kev hloov pauv muaj qhov cuam tshuam tsis tseem ceeb rau kev siv laser thiab nws cov txheej txheem vuam sib xyaw. Cov yam ntxwv no hauv cov txheej txheem vuam ncaj qha lossis tsis ncaj qha cuam tshuam qhov ruaj khov ntawm cov txheej txheem vuam rau qee qhov, thiab tuaj yeem txiav txim siab qhov zoo ntawm qhov vuam. Qhov kev sib txuas ntawm ob qhov chaw cua sov ntawm laser thiab arc tuaj yeem ua rau ob qhov chaw cua sov muab kev ua si tag nrho rau lawv tus kheej cov yam ntxwv thiab tau txais cov txiaj ntsig vuam zoo dua li ib qho laser vuam thiab arc vuam. Piv nrog rau txoj kev vuam laser autogenous, txoj kev vuam no muaj qhov zoo ntawm qhov sib txawv muaj zog thiab qhov tuab weldable loj. Piv nrog rau qhov sib txawv nqaim laser hlau sau vuam txoj kev ntawm cov phaj tuab, nws muaj qhov zoo ntawm cov hlau yaj siab thiab cov nyhuv fusion zoo. . Tsis tas li ntawd, qhov kev nyiam ntawm laser rau arc txhim kho kev ruaj khov ntawm arc, ua rau laser-arc hybrid vuam sai dua li cov tsoos arc vuam thiablaser filler hlau vuam, nrog rau kev ua haujlwm vuam zoo heev.
03 Daim ntawv thov vuam siv laser-arc hybrid muaj zog heev
Cov thev naus laus zis vuam laser-arc hybrid muaj zog heev yog siv dav hauv kev lag luam tsim nkoj. Meyer Shipyard hauv lub tebchaws Yelemees tau tsim ib txoj kab ntau lawm 12kW CO2 laser-arc hybrid vuam rau vuam lub hull tiaj tiaj thiab cov khoom siv tawv kom ua tiav kev tsim cov fillet welds ntev 20m hauv ib zaug thiab txo qhov degree ntawm deformation los ntawm 2/3. GE tau tsim ib lub fiber laser-arc hybrid vuam system nrog lub zog tso zis siab tshaj plaws ntawm 20kW los vuam lub USS Saratoga aircraft carrier, txuag tau 800 tons ntawm cov hlau vuam thiab txo cov neeg ua haujlwm teev sijhawm los ntawm 80%, raws li pom hauv Daim Duab 3. CSSC 725 siv 20kW fiber laser high-power laser-arc hybrid vuam system, uas tuaj yeem txo qhov deformation vuam los ntawm 60% thiab nce kev vuam efficiency los ntawm 300%. Shanghai Waigaoqiao Shipyard siv 16kW fiber laser high-power laser-arc hybrid vuam system. Cov kab ntau lawm siv cov txheej txheem tshiab ntawm laser hybrid welding + MAG welding kom ua tiav ib sab ib zaug welding thiab ob sab tsim ntawm 4-25mm tuab hlau phaj. High-power laser-arc hybrid welding technology yog siv dav hauv cov tsheb armored. Nws cov yam ntxwv vuam yog: welding ntawm cov qauv hlau loj-tuab, tus nqi qis, thiab kev tsim khoom zoo.
