Laser Welding Principles and Process Applications

Mfundo Zowotcherera Laser

Kuwotcherera kwa laserimagwiritsa ntchito mayendedwe abwino kwambiri komanso mawonekedwe amphamvu kwambiri amtengo wa laser kuti agwire ntchito.Kupyolera mu dongosolo la kuwala, mtengo wa laser umayang'ana pa malo ang'onoang'ono kwambiri, kupanga gwero la kutentha kwambiri kwa nthawi yochepa kwambiri.Izi zimasungunula zinthuzo pamalo owotcherera, ndikupanga malo olimba a weld ndi msoko.

·Kuwotcherera kwa laser kumagawika kukhala kuwotcherera kwa conduction ndi kuwotcherera kozama.

·Kuchuluka kwamphamvu kwa laser kwa 10⁵~10⁶w/cm²kumabweretsa kuwotcherera laser conduction.

·Kuchuluka kwamphamvu kwa laser kwa 10⁵~10⁶w/cm²kumabweretsa kuwotcherera kwa laser deep.

Makhalidwe a Laser Welding

Poyerekeza ndi njira zina kuwotcherera, laser kuwotcherera ali ndi makhalidwe awa:

·Mphamvu zokhazikika, mphamvu zowotcherera kwambiri, kulondola kwapamwamba kwambiri, komanso kuchuluka kwakuya mpaka m'lifupi kwa msoko wowotcherera.

·Kuyika kwa kutentha pang'ono, chigawo chaching'ono chokhudzidwa ndi kutentha, kupanikizika kochepa kotsalira, ndi kusinthika kochepa kwa workpiece.

·Kuwotcherera osalumikizana, kutumiza kwa fiber optic, kupezeka kwabwino, komanso makina apamwamba kwambiri.

·flexible olowa kapangidwe, kupulumutsa zopangira.

·Mphamvu zowotcherera zimatha kuyendetsedwa bwino, kuwonetsetsa kuti zowotcherera zizikhala zokhazikika komanso mawonekedwe abwino.

Njira Yowotchera Laser ya Zida Zachitsulo

Kuwotcherera kwa Zitsulo ndi Aloyi ake

·Chitsulo chosapanga dzimbiri chikhoza kupeza zotsatira zabwino zowotcherera pogwiritsa ntchito mafunde amtundu wa square.

·Popanga zida zowotcherera, yesetsani kuti ma weld atalikirane ndi zinthu zopanda zitsulo momwe mungathere.

·Kuti mukwaniritse zofunikira zamphamvu ndi mawonekedwe, ndikofunikira kusunga malo okwanira kuwotcherera ndi makulidwe a workpiece.

·Pa kuwotcherera, ndikofunika kuonetsetsa ukhondo wa workpiece ndi kuuma kwa chilengedwe.

Kuwotcherera Aluminium ndi Aloyi ake

MFUNDO ZA LASER WEDING NDI NTCHITO NTCHITO.3

·Aluminiyamu aloyi zipangizo ndi mkulu reflectivity;Choncho, mkulu laser nsonga mphamvu chofunika pa kuwotcherera.

·Ming'alu sachedwa kuchitika pa kugunda malo kuwotcherera, zimakhudza kuwotcherera mphamvu.

·Zomwe zimapangidwira zimakhala zosavuta kusankhana, zomwe zimatsogolera ku splattering.Ndikoyenera kusankha zipangizo zapamwamba kwambiri.

·Nthawi zambiri, kugwiritsa ntchito malo akulu kukula ndi kugunda kwakutali kumatha kukwaniritsa zotsatira zabwino zowotcherera.

Kuwotcherera kwa Copper ndi Aloyi ake

·Zipangizo zamkuwa zimakhala ndi mawonekedwe apamwamba poyerekeza ndi ma aloyi a aluminiyamu, zomwe zimafunikira mphamvu yapamwamba kwambiri ya laser pakuwotcherera.Mutu wa laser uyenera kupendekeka pamakona ena.

·Kwa ma aloyi ena amkuwa, monga mkuwa ndi mkuwa, zovuta zowotcherera zimachulukitsidwa chifukwa cha mphamvu ya zinthu za alloy.Chisamaliro chiyenera kuperekedwa pakusankha magawo a ndondomeko yowotcherera.

Zowotcherera Zosiyanasiyana za Metal

MFUNDO ZA LASER WEDING NDI NTCHITO NTCHITO.5

·Kodi njira yolimba ingapangidwe.

·Kodi pali kusiyana kwakukulu mu electronegativity pakati pa zitsulo zosiyana?

·Zinthu zina zokopa.

Kaya zitsulo zosiyana zimatha kupanga zolumikizira zapamwamba kwambiri zimatengera momwe zitsulo zimapangidwira, mankhwala, kapangidwe kake, komanso miyeso yazitsulo zomwe zimayenera kuwotcherera.Izi kawirikawiri zimaganiziridwa kuchokera kuzinthu zotsatirazi:

·Kaya yankho lolimba likhoza kupangidwa zimadalira ngati zitsulo zosiyana zingathe kusungunuka mumadzimadzi ndi zolimba.Pokhapokha atasungunuka wina ndi mzake kwamuyaya, mgwirizano wamphamvu ndi wolimba weld ungapangidwe.Nthawi zambiri, kusungunuka kwakukulu, kapena kusungunuka kopanda malire, kumatheka pokhapokha kusiyana kwa ma atomiki pakati pa zitsulo ziwirizi ndi zosakwana 14% mpaka 15%.

·Kaya pali kusiyana kwakukulu mu electronegativity pakati pa zitsulo zosiyana ndizofunikanso.Kusiyanitsa kwakukulu, kumalimbitsa mgwirizano wawo wamankhwala, womwe umayambitsa kupanga mapangidwe m'malo mwa njira zolimba.Zotsatira zake, kusungunuka kwa njira yolimba yomwe imapangidwira kumachepetsedwa, ndipo mphamvu ya weld joint imakhalanso yotsika.

·Kuphatikiza apo, kuwotcherera kwa zitsulo zosiyana kumakhudzidwa kwambiri ndi zinthu monga malo osungunuka, ma coefficients a kukulitsa kwamafuta, ma conductivity amafuta, kutentha kwapadera, oxidizability, ndi kuwunikira kwazinthu zomwe zikukhudzidwa.Kusiyana kwakukulu kwa zinthu zakuthupi izi, kumakhala kovuta kwambiri kuwotcherera, ndipo mphamvu yowotcherera imachepa mphamvu.

·Nthawi zambiri, kuwotcherera kwa laser kwa zida zachitsulo zofananira monga chitsulo chokhala ndi mkuwa, aluminiyamu, ndi faifi tambala, komanso mkuwa wokhala ndi faifi tambala, kumawonetsa kuwotcherera kwabwino, zomwe zimapangitsa kuti pakhale kuwotcherera kokwanira.

Minda Yogwiritsira Ntchito Laser Welding

Kuwotcherera kwa laser kumapeza ntchito zambiri m'magawo osiyanasiyana, kuphatikiza koma osati kumadera awa:

1: Kuwotcherera Kwachitsulo Kosiyana

Kuwotcherera kwa laser kumagwiritsidwa ntchito kwambiri m'mafakitale opanga monga magalimoto, ndege, zamagetsi, ndi uinjiniya wamakina.Amagwiritsidwa ntchito popangira zida zowotcherera ndi kusonkhanitsa zida, kukulitsa luso lazopanga komanso mtundu wazinthu.

2: Zida Zachipatala

Popanga zida zachipatala, kuwotcherera kwa laser kumagwiritsidwa ntchito polumikiza ndi kusonkhanitsa tinthu tating'onoting'ono, zolondola, kuonetsetsa kuti zinthu zili bwino kwambiri ndikupewa kutentha kwambiri kwa zinthu.

3: Zamagetsi

Chifukwa cha kulondola kwake komanso kutentha pang'ono, kuwotcherera kwa laser kumagwiritsidwa ntchito kwambiri popanga zida zamagetsi, kuphatikiza kuwotcherera kwa board board ndi ma microelectronic components.

4: Zamlengalenga

Kuwotcherera kwa laser kumagwiritsidwa ntchito m'gawo lazamlengalenga popanga ndege ndi zida zam'mlengalenga, kupangitsa mapangidwe opepuka komanso kulumikizana kwamphamvu kwambiri.

5: Gawo la Mphamvu

M'makampani amagetsi, kuwotcherera kwa laser kumagwiritsidwa ntchito popanga ma solar, zida zamagetsi za nyukiliya, ndi zida zina zokhudzana ndi kupanga mphamvu.

6: Zodzikongoletsera ndi Kupanga Mawotchi

Potengera kusinthika kwake kuzinthu zabwino komanso zovuta, kuwotcherera kwa laser nthawi zambiri kumagwiritsidwa ntchito popanga zodzikongoletsera ndi mawotchi polumikiza ndi kukonza zida zofooka.

7: Makampani Oyendetsa Magalimoto

Popanga magalimoto, kuwotcherera kwa laser kumagwiritsidwa ntchito kulumikiza zida zamagalimoto, kukonza bwino kuwotcherera, komanso kukulitsa mtundu wazinthu.

Ponseponse, kulondola kwambiri, kuthamanga, komanso kusinthasintha kwa kuwotcherera kwa laser kumapangitsa kuti izigwiritsidwa ntchito kwambiri m'magawo opanga ndi kupanga.
