01 Wowotcherera wosakanizidwa wa laser-arc hybrid plate
Kuwotcherera mbale (manenedwe ≥ 20mm) kuwotcherera kumagwira ntchito yofunika kwambiri popanga zida zazikulu m'magawo ofunikira monga zakuthambo, kuyenda ndi kupanga zombo, mayendedwe a njanji, etc. Zigawo izi nthawi zambiri zimadziwika ndi makulidwe akulu, mawonekedwe olumikizana ovuta, ndi ntchito zovuta. chilengedwe. Kuwotcherera khalidwe kumakhudza mwachindunji ntchito ndi moyo wa zida. Chifukwa cha liwiro lowotcherera pang'onopang'ono komanso zovuta zazikulu za spatter, njira yowotcherera yotetezedwa ndi gasi imakumana ndi zovuta monga kutsika pang'ono, kugwiritsa ntchito mphamvu zambiri, komanso kupsinjika kwakukulu kotsalira, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zomwe zikuchulukirachulukira zopangira. Komabe, ukadaulo wowotcherera wa laser-arc wosakanizidwa ndi wosiyana ndi ukadaulo wachikhalidwe. Iwo bwinobwino Chili ubwino walaser kuwotchererandi kuwotcherera arc, ndipo ali ndi mikhalidwe yakuzama kwakukulu kolowera, liwiro lowotcherera mwachangu, kuchita bwino kwambiri komanso mtundu wabwino wa weld, monga momwe tawonetsera pa Chithunzi 1 Onetsani. Chifukwa chake, ukadaulo uwu wakopa chidwi chambiri ndipo wayamba kugwiritsidwa ntchito m'malo ena ofunikira.
Chithunzi 1 Mfundo ya laser-arc hybrid kuwotcherera
02Fufuzani pa kuwotcherera kwa laser-arc hybrid yama mbale wandiweyani
Norwegian Institute of Industrial Technology ndi Lule University of Technology ku Sweden adaphunzira kufanana kwapang'onopang'ono kwa ma welds ophatikizika pansi pa 15kW kwa chitsulo chokhuthala cha 45mm champhamvu champhamvu chochepa. Yunivesite ya Osaka ndi Central Metallurgical Research Institute ya ku Egypt inagwiritsa ntchito laser ya 20kW kuti ipange kafukufuku pa njira yowotcherera ya laser-arc hybrid ya mbale zokhuthala (25mm), pogwiritsa ntchito liner kuti athetse vuto la hump. Kampani ya Danish Force Technology Company idagwiritsa ntchito ma lasers awiri a 16 kW disk motsatizana pochita kafukufuku wowotcherera wosakanizidwa wa mbale zachitsulo za 40mm wandiweyani pa 32 kW, kusonyeza kuti kuwotcherera kwamphamvu kwambiri kwa laser-arc kukuyembekezeka kugwiritsidwa ntchito powotcherera pansanja yam'mphepete mwa nyanja. , monga momwe tawonetsera pa Chithunzi 2. Harbin Welding Co., Ltd. ndi yoyamba m'dzikoli kudziwa luso lamakono lamakono ndi luso lophatikizana ndi zipangizo zamakono zamphamvu kwambiri zosungunuka laser electrode arc hybrid heat source kuwotcherera. Ndikoyamba kugwiritsa ntchito bwino luso lamphamvu kwambiri la laser-dual-wire melt electrode arc hybrid welding ukadaulo ndi zida pazida zapamwamba kwambiri mdziko langa. kupanga.
Chithunzi 2. Chithunzi cha masanjidwe a laser
Malinga ndi kafukufuku waposachedwa wa laser-arc hybrid kuwotcherera kwa mbale wandiweyani kunyumba ndi kunja, zitha kuwoneka kuti kuphatikiza kwa laser-arc hybrid njira yowotcherera ndi yopapatiza poyambira kumatha kukwaniritsa kuwotcherera kwa mbale zokhuthala. Mphamvu ya laser ikakwera mpaka ma Watts opitilira 10,000, kuyatsa kwa laser yamphamvu kwambiri, mawonekedwe a vaporization azinthuzo, kulumikizana pakati pa laser ndi plasma, kukhazikika kwamadzi osungunuka amadzimadzi, njira yosinthira kutentha, ndi khalidwe lazitsulo la weld Kusintha kudzachitika mosiyanasiyana. Pamene mphamvu ikuwonjezeka ku ma Watts oposa 10,000, kuwonjezeka kwa mphamvu zowonjezera mphamvu kudzakulitsa kuchuluka kwa vaporization m'dera pafupi ndi dzenje laling'ono, ndipo mphamvu yowonongeka idzakhudza mwachindunji kukhazikika kwa dzenje laling'ono ndi kutuluka kwa dziwe losungunuka, potero zimakhudza njira kuwotcherera. Zosinthazi zili ndi vuto losanyozeka pakukhazikitsa laser ndi njira zake zowotcherera. Zochitika zodziwika mu njira yowotcherera mwachindunji kapena mwanjira ina zikuwonetsa kukhazikika kwa njira yowotcherera kumlingo wina, ndipo zimatha kudziwanso mtundu wa weld. Kuphatikizika kwa magwero awiri otentha a laser ndi arc kungapangitse magwero awiri otenthawa kuti azisewera kwathunthu ku mawonekedwe awo ndikupeza zotsatira zabwinoko zowotcherera kuposa kuwotcherera kwa laser imodzi ndi kuwotcherera kwa arc. Poyerekeza ndi njira kuwotcherera laser autogenous, njira kuwotcherera ili ndi ubwino amphamvu kusiyana kusinthasintha ndi makulidwe lalikulu weldable. Poyerekeza ndi njira yopapatiza ya laser yodzaza waya yama mbale wandiweyani, ili ndi zabwino zake pakusungunuka kwa waya komanso kuphatikizika kwabwino kwa groove. . Kuphatikiza apo, kukopa kwa laser ku arc kumathandizira kukhazikika kwa arc, ndikupanga kuwotcherera kwa ma laser-arc hybrid mwachangu kuposa kuwotcherera kwachikhalidwe komansolaser filler waya kuwotcherera, ndi mphamvu kwambiri kuwotcherera.
03 Kugwiritsa ntchito kuwotcherera kwamphamvu kwambiri kwa laser-arc hybrid
Ukadaulo wamphamvu kwambiri wa laser-arc hybrid wowotcherera umagwiritsidwa ntchito kwambiri pantchito yomanga zombo. Meyer Shipyard ku Germany yakhazikitsa chingwe chowotcherera cha 12kW CO2 laser-arc hybrid chowotcherera mbale zathyathyathya ndi zouma kuti zitheke kupanga ma welds aatali a 20m nthawi imodzi ndikuchepetsa kupindika ndi 2/3. GE inapanga makina owotcherera a fiber laser-arc hybrid okhala ndi mphamvu yayikulu yotulutsa 20kW kuwotcherera chonyamulira chandege cha USS Saratoga, kupulumutsa matani 800 azitsulo zowotcherera ndikuchepetsa maola amunthu ndi 80%, monga momwe zikusonyezedwera pa Chithunzi 3. CSSC 725 imagwiritsa ntchito 20kW CHIKWANGWANI laser mkulu-mphamvu laser-arc wosakanizidwa kuwotcherera dongosolo, amene angathe kuchepetsa kuwotcherera mapindikidwe ndi 60% ndi kuonjezera kuwotcherera bwino ndi 300%. Shanghai Waigaoqiao Shipyard amagwiritsa 16kW CHIKWANGWANI laser mkulu-mphamvu laser-arc makina wosakanizidwa kuwotcherera. Mzere wopanga umatenga ukadaulo watsopano wa laser hybrid welding + MAG kuwotcherera kuti mukwaniritse zowotcherera zambali imodzi ndikupanga mbali ziwiri zazitsulo zazitsulo za 4-25mm. Ukadaulo wamphamvu kwambiri wa laser-arc hybrid wowotcherera umagwiritsidwa ntchito kwambiri pamagalimoto okhala ndi zida. Makhalidwe ake kuwotcherera ndi: kuwotcherera kwazitsulo zazikulu zazikulu zolimba, zotsika mtengo, komanso kupanga kochita bwino kwambiri.
Chithunzi 3. USS Sara Toga chonyamulira ndege
Ukadaulo wowotcherera wamphamvu kwambiri wa laser-arc hybrid wowotcherera wayamba kugwiritsidwa ntchito m'mafakitale ena ndipo udzakhala njira yofunikira popanga zida zazikulu zokhala ndi makulidwe apakatikati ndi akulu. Pakalipano, pali kusowa kwa kafukufuku pa makina opangira magetsi osakanikirana a laser-arc, omwe amafunika kulimbikitsidwa kwambiri, monga kugwirizana pakati pa photoplasma ndi arc ndi kugwirizana pakati pa arc ndi dziwe losungunuka. Palinso mavuto ambiri omwe sanathe kuthetsedwa mu njira yowotcherera yamphamvu kwambiri ya laser-arc hybrid, monga zenera lopapatiza, mawonekedwe osagwirizana ndi makina a weld, komanso kuwongolera kowotcherera kwakanthawi. Pamene mphamvu yotulutsa ma lasers amakampani akuchulukirachulukira pang'onopang'ono, ukadaulo wapamwamba kwambiri wa laser-arc hybrid wowotcherera udzakula mwachangu, ndipo umisiri watsopano wowotcherera wa laser wosakanizidwa upitilira kuwonekera. Localization, lalikulu ndi luntha adzakhala zinthu zofunika pa chitukuko cha mkulu-mphamvu laser kuwotcherera zida m'tsogolo.
