Cov khoom no feem ntau yog cov tuab tuab, cov ntaub ntawv sib koom ua ke, thiab cov kev pabcuam nyuaj. ib puag ncig. Vuam zoo muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm thiab lub neej ntawm cov khoom siv. Vim qhov kev sib tsoo qeeb qeeb thiab cov teeb meem loj heev, cov roj siv hluav taws xob tiv thaiv vuam txoj kev ntsib cov teeb meem xws li kev siv vuam qis, kev siv hluav taws xob siab, thiab kev ntxhov siab loj, ua rau nws nyuaj rau kev ua kom tau raws li qhov yuav tsum tau ua ntau ntxiv. Txawm li cas los xij, laser-arc hybrid vuam thev naus laus zis yog qhov sib txawv ntawm cov tshuab vuam tsoos. Nws ntse combines qhov zoo ntawmlaser vuamthiab arc vuam, thiab muaj cov yam ntxwv ntawm qhov tob tob tob, vuam ceev, kev ua haujlwm siab thiab zoo dua vuam zoo, raws li qhia hauv daim duab 1 Qhia. Yog li ntawd, cov cuab yeej no tau nyiam cov neeg tuaj saib thiab tau pib siv hauv qee qhov chaw tseem ceeb.
Daim duab 1 Txoj Cai ntawm laser-arc hybrid vuam
02 Tshawb nrhiav ntawm laser-arc hybrid vuam ntawm daim hlau tuab
Lub Norwegian Institute of Industrial Technology thiab Lule University of Technology hauv Sweden tau kawm txog cov qauv kev sib xws ntawm cov pob qij txha sib txuas hauv qab 15kW rau 45mm tuab micro-alloyed high-strength low-alloy steel. Osaka University thiab Egypt lub koom haum Central Metallurgical Research Institute tau siv 20kW fiber ntau laser los ua kev tshawb fawb ntawm ib leeg-pass laser-arc hybrid vuam txheej txheem ntawm tuab daim hlau (25 hli), siv lub hauv qab liner los daws qhov teeb meem hauv qab hump. Lub tuam txhab Danish Force Technology siv ob lub 16 kW disk lasers nyob rau hauv series los ua kev tshawb fawb ntawm hybrid vuam ntawm 40mm tuab steel daim hlau ntawm 32 kW, qhia tias high-power laser-arc vuam yuav tsum tau siv nyob rau hauv offshore cua zog ntauwd puag vuam. , raws li qhia nyob rau hauv daim duab 2. Harbin Welding Co., Ltd. high-power khoom laser-melting electrode arc hybrid tshav kub qhov chaw vuam. Nws yog thawj zaug kom ua tiav cov khoom siv hluav taws xob laser-dual-xaim melting electrode arc hybrid vuam tshuab thiab cov cuab yeej siv rau cov khoom siv high-end hauv kuv lub teb chaws. kev tsim khoom.
Daim duab 2. Laser installation layout daim duab
Raws li kev tshawb fawb tam sim no ntawm laser-arc hybrid vuam ntawm cov phaj tuab hauv tsev thiab txawv teb chaws, nws tuaj yeem pom tau tias kev sib xyaw ntawm laser-arc hybrid vuam txoj kev thiab nqaim qhov sib txawv tuaj yeem ua tiav cov vuam ntawm cov phaj tuab. Thaum lub zog laser nce mus rau ntau tshaj 10,000 watts, nyob rau hauv irradiation ntawm high-zog laser, vaporization tus cwj pwm ntawm cov khoom, cov txheej txheem cuam tshuam ntawm laser thiab plasma, lub xeev ruaj khov ntawm lub pas dej ua ke molten, lub tshav kub hloov mechanism, thiab tus cwj pwm metallurgical ntawm cov weld Kev hloov pauv yuav tshwm sim rau qhov sib txawv. Raws li lub zog nce mus rau ntau tshaj 10,000 watts, qhov nce ntawm lub zog ceev yuav ua kom cov qib ntawm vaporization nyob rau hauv thaj tsam ze ntawm lub qhov me me, thiab lub zog recoil yuav cuam tshuam ncaj qha rau kev ruaj ntseg ntawm lub qhov me me thiab qhov ntws ntawm lub pas dej molten, yog li no cuam tshuam rau cov txheej txheem vuam. Cov kev hloov pauv muaj qhov cuam tshuam tsis zoo rau kev siv laser thiab nws cov txheej txheem vuam sib xyaw. Cov yam ntxwv zoo li no hauv cov txheej txheem vuam ncaj qha lossis tsis ncaj qha cuam tshuam qhov kev ruaj ntseg ntawm cov txheej txheem vuam rau qee qhov, thiab tuaj yeem txiav txim siab qhov zoo ntawm cov vuam. Cov nyhuv coupling ntawm ob qhov chaw tshav kub ntawm laser thiab arc tuaj yeem ua rau ob lub tshav kub qhov chaw muab kev ua si tag nrho rau lawv tus kheej cov yam ntxwv thiab tau txais cov teebmeem vuam zoo dua li ib qho laser vuam thiab arc vuam. Piv nrog rau cov txheej txheem laser autogenous vuam, txoj kev vuam no muaj qhov zoo ntawm qhov sib txawv ntawm qhov sib txawv thiab loj weldable thickness. Piv nrog rau qhov sib txawv nqaim laser hlau filling vuam txoj kev ntawm daim hlau tuab, nws muaj qhov zoo ntawm cov hlau melting efficiency thiab zoo groove fusion nyhuv. . Tsis tas li ntawd, qhov attraction ntawm lub laser rau lub arc txhim khu kev ruaj ntseg ntawm arc, ua laser-arc hybrid vuam sai dua li ib txwm arc vuam thiablaser muab tub lim welding, nrog kuj zoo vuam efficiency.
03 High-power laser-arc hybrid vuam daim ntawv thov
High-power laser-arc hybrid vuam tshuab yog dav siv nyob rau hauv kev lag luam shipbuilding. Meyer Shipyard nyob rau hauv lub teb chaws Yelemees tau tsim ib tug 12kW CO2 laser-arc hybrid vuam ntau lawm kab rau vuam hull tiaj daim hlau thiab stiffeners kom ua tiav cov tsim ntawm 20m ntev fillet welds nyob rau hauv ib tug mus thiab txo cov degree ntawm deformation los ntawm 2/3. GE tsim lub fiber ntau laser-arc hybrid welding system nrog lub siab tshaj plaws tso zis zog ntawm 20kW rau vuam USS Saratoga aircraft carrier, txuag 800 tons ntawm weld hlau thiab txo tus txiv neej-teev teev los ntawm 80%, raws li qhia nyob rau hauv daim duab 3.
