Buku Lofotokozera Njira ndi Makhalidwe Othandizira Kuwotcherera ndi Laser

1. Kuwotcherera kwa Laser Fusion

    

   Laser ndi mtundu wa kuwala komwe kumakhala ndi mphamvu zambiri komanso mphamvu zambiri, komwe kumatha kusungunula ndi kutentha zinthu mkati mwa mtunda wochepa. Chifukwa chake, zimathandiza kulumikizana bwino kwa chinthu chilichonse.

    
2. Kuwotcherera kwa Laser-Arc Hybrid

    

   Mtambo wa laser wotulutsidwa ndi jenereta ya laser umapanga dziwe losungunuka pa workpiece kuti lilumikizidwe kudzera mu waya wothira. Kenako arc imagwiritsidwa ntchito kusungunula workpiece kapena kuyika ma weldments pamodzi kuti amalize ntchito yowotcherera.

    
3. Kupaka Laser

    

   Jenereta yapadera ya laser ndi mutu wapadera wa nozzle kapena brazing zimagwiritsidwa ntchito kutentha chogwirira ntchitocho mu mawonekedwe a arc kapena kuwala kwa kuwala, potero zimapangitsa kuti chiwongolerocho chikhale cholimba.

    
4. Kuwotcherera kwa Laser Sungunulani

    

   Jenereta ya laser imatulutsa kuwala kwa laser kuti itenthe chitsulocho mpaka chitasungunuka, kenako chitsulo chosungunukacho chimapopera pa chogwirira ntchito kudzera mu nozzle kuti chigwire ntchito yowotcherera.

    

Makhalidwe a Kuwotcherera kwa Laser

1. Kuwotcherera pamwamba kosakhudzana

    

   Kuwotcherera kumachitika pamwamba pa chinthucho popanda kukhudza pamwamba pa chinthucho, zomwe zimapangitsa kuti chikhale choyenera kugwiritsa ntchito chitsulo kapena alloy iliyonse—makamaka zipangizo zomwe sizingawotchedzeredwe ndi njira zachikhalidwe.

    
   Pa nthawi yowotcherera ndi laser, laser imasamutsa mphamvu kupita ku chinthucho kudzera mu reflector, ndipo laser imabwereranso ku jenereta. Pamene kuwala kwa laser kumadutsa mu chinthucho kuti chiwotcheredwe, dziwe losungunuka limapangidwa pamwamba pa chinthucho. Izi zimathandiza kuti kuwotcherera ndi laser kulumikizane molondola kwambiri, komanso ngakhale zogwirira ntchito zowotcherera zikhale zokhuthala kuposa zomwe zimagwirizana ndi zipangizo zachikhalidwe zowotcherera.
    
   Ubwino: Wokhoza kulumikiza zinthu zosiyanasiyana (kuphatikizapo zinthu zophatikizika).

    

   Zoyipa: Imafuna majenereta amphamvu a laser komanso zida zothandizira kuwotcherera.

    
2. Kusinthasintha kwa Maonekedwe Ovuta

    

   Poyerekeza ndi argon arc welding, laser welding imatha kugwira ziwalo zokhala ndi mawonekedwe osiyanasiyana ovuta.

    
   Mwachitsanzo, imatha kulumikiza zitsulo monga chitsulo, mkuwa ndi aluminiyamu pamene ikutsimikizira kuti kulumikiza kwapamwamba kwambiri. Imagwira ntchito polumikiza mawonekedwe ang'onoang'ono pa mainchesi ang'onoang'ono, ndipo imatha kulumikiza zigawo zokhala ndi mainchesi osakwana 1 mm koma zolemera zoposa magalamu 200. Kuphatikiza apo, chifukwa cha kugwiritsa ntchito majenereta amphamvu kwambiri a laser, ntchito zolumikiza laser zitha kuchitika popanda zida zina zowonjezera. Chifukwa chake, kulumikiza laser fusion kumagwiritsidwa ntchito kwambiri popanga mafakitale.
    
3. Palibe Kutentha Kofunikira (Nthawi zambiri)

    

   Kutenthetsa sikofunikira nthawi zambiri (kutengera zomwe zimachitika; zipangizo zina zingafunike kutenthetsa). Njira yowotcherera sikutanthauza kutentha, kuonetsetsa kuti dziwe losungunuka limakhala lokhazikika. Njira yapadera yowotcherera iyi imapeza ubwino wake m'malo omwe njira zambiri zopangira zinthu zachikhalidwe sizili bwino kapena zokwera mtengo. Popeza palibe kutentha komwe kumachitika panthawi yowotcherera, kuwotcherera kwa laser kumachotsa kufunikira kwa njira zotenthetsera ndi kuziziritsa. Ikhoza kuwonetsetsa kuti chitsulo chowotcherera chili ndi mawonekedwe abwino kwambiri, malo omwe amakhudzidwa ndi kutentha komanso anisotropy. Ma weld ali ndi mawonekedwe abwino kwambiri amakanika, zomwe zimapangitsa kuti kuwotcherera kwa laser kugwiritsidwe ntchito kwambiri m'magawo osiyanasiyana amafakitale—makamaka m'mafakitale opanga magalimoto, makina ndi ntchito zachitsulo.

    
4. Kukonzekera Kosavuta kwa Ntchito Yopangira Ntchito

    

   Malo ogwirira ntchito safuna chisamaliro chapadera monga kupukuta kapena kupukuta. Ntchito yake ndi yosavuta komanso yosavuta, chifukwa zida zowotcherera za laser zimatha kuwotcherera mwachindunji malo ogwirira ntchito.

    
   Ntchito Yogwiritsidwa Ntchito: Kuwotcherera matupi a magalimoto, zida zamakanika, nkhungu, zolumikizira mapaipi, ndi zina zotero. Ndi yoyenera zipangizo zonse zachitsulo, monga mkuwa, aluminiyamu, chitsulo chosapanga dzimbiri ndi zitsulo zina zapadera za alloy, ndipo ingagwiritsidwe ntchito kwambiri popanga matupi a magalimoto, kupanga zida zamafakitale ndi madera ena.
    
5. Waya Wowotcherera Wochepa Kapena Wosafunikira

    

   Kuwotcherera kumatha kuchitika ndi waya wowotcherera wochepa kapena wopanda, motero kuchepetsa ndalama ndi nthawi yogwiritsidwa ntchito. (Muzochitika zapadera, kugwiritsa ntchito waya wowotcherera kumadalira zofunikira pa ndondomekoyi.)

    
   Chifukwa chake, nthawi zambiri,kuwotcherera kwapamwamba kwambiriZotsatira zake zitha kupezeka pogwiritsa ntchito waya wowotcherera pang'ono kapena mphamvu yochepa ya laser.
