Ukadaulo wolumikizira laser, kapena ukadaulo wowotcherera laser, umagwiritsa ntchito kuwala kwa laser kwamphamvu kwambiri kuti uyang'ane ndikulamulira kuwala kwa pamwamba pa zinthuzo, ndipo pamwamba pake pamatenga mphamvu ya laser ndikuisintha kukhala mphamvu yotentha, zomwe zimapangitsa kuti zinthuzo zitenthe ndikusungunuka, kutsatiridwa ndi kuzizira ndi kuuma kuti zinthu zofanana kapena zosiyana zigwirizane. Njira yowotcherera laser imafuna mphamvu ya laser ya 104mpaka 108W/cm2Poyerekeza ndi njira zachikhalidwe zowotcherera, kuwotcherera pogwiritsa ntchito laser kuli ndi ubwino wotsatirawu.

Mtambo wa plasma umodzi, zinthu zosungunuka ziwiri, dzenje la makiyi atatu, kuzama kwa kusakanikirana kwa madzi ndi kuya kwa madzi ndi 4
Chifukwa cha kukhalapo kwa chitseko cha kiyi, kuwala kwa laser, pambuyo powunikira mkati mwa chitseko cha kiyi, kudzawonjezera kuyamwa kwa laser ndi zinthuzo ndikulimbikitsa kupangika kwa dziwe losungunuka pambuyo pobalalika ndi zotsatira zina, njira ziwiri zowotcherera zikuyerekezeredwa motere.
Chithunzi chomwe chili pamwambapa chikupereka njira yowotcherera ya laser ya chinthu chomwecho ndi gwero lomwelo la kuwala, njira yosinthira mphamvu imachitika kudzera mu dzenje la keyboo, dzenje la keyboo ...
Ngati zinthu zomwe zikulumikizidwa ndi chitsulo chosiyana, kukhalapo kwa kusiyana kwa mphamvu ya kutentha kudzakhudza kwambiri njira yolumikizira, monga kusiyana kwa malo osungunuka, kutentha koyendetsedwa, mphamvu yeniyeni ya kutentha, ndi ma coefficients okulitsa a zipangizo zosiyanasiyana, zomwe zimapangitsa kuti kupsinjika kwa kulumikiza, kusintha kwa kulumikiza, ndi kusintha kwa momwe chitsulo cholumikizirana chimagwirira ntchito, zomwe zimapangitsa kuti mphamvu ya makina ya kulumikiza ichepe.
Chifukwa chake, malinga ndi makhalidwe osiyanasiyana a malo owetera, njira yowetera yapanga kuwotcherera kwa laser filler, laser brazing, dual-beam laser welding, laser composite welding, ndi zina zotero.
Kuwotcherera kwa Laser Waya
Mu njira yowotcherera ya laser ya aluminiyamu, titaniyamu ndi aloyi amkuwa, chifukwa cha kuyamwa kochepa kwa kuwala kwa laser (<10%) m'zinthuzi, plasma yopangidwa ndi chithunzi imakhala ndi chitetezo cha kuwala kwa laser, kotero zimakhala zosavuta kupanga madontho ndikupangitsa kuti pakhale zolakwika monga ma porosity ndi ming'alu. Kuphatikiza apo, khalidwe la kuwotcherera limakhudzidwanso pamene kusiyana pakati pa zinthu zogwirira ntchito kuli kwakukulu kuposa kukula kwa malo panthawi yopopera mbale yopyapyala.
Pothetsa mavuto omwe ali pamwambapa, zotsatira zabwino zowotcherera zitha kupezeka pogwiritsa ntchito njira yodzaza. Chodzazacho chingakhale waya kapena ufa, kapena njira yodzaza yomwe idakhazikitsidwa kale ingagwiritsidwe ntchito. Chifukwa cha malo ochepa omwe ali olunjika, chowunjikiracho chimakhala chopapatiza ndipo chimakhala ndi mawonekedwe ozungulira pang'ono pamwamba pake chikagwiritsidwa ntchito chodzazacho.
Kupaka Laser
Mosiyana ndi fusion welding, yomwe imasungunula magawo awiri olumikizidwa nthawi imodzi, brazing imawonjezera filler tool yokhala ndi melting point yotsika kuposa ground tool pamwamba pa weld, imasungunula filler tool kuti idzaze mpata pa kutentha kotsika kuposa melting point ya ground tool komanso pamwamba kuposa melting point ya filler tool, kenako imaundana kuti ipange solid weld.
Kukonza zitsulo zopyapyala n'koyenera zipangizo zamagetsi zomwe zimakhudzidwa ndi kutentha, mbale zopyapyala, ndi zinthu zachitsulo zosasinthasintha.
Kuphatikiza apo, ikhoza kugawidwanso m'magulu monga soft brazing (<450 °C) ndi hard brazing (>450 °C) kutengera kutentha komwe brazing imatenthetsera.
Kuwotcherera kwa Laser kwa Mtanda Wawiri
Kuwotcherera kwa mipiringidzo iwiri kumalola kuwongolera nthawi ndi malo owunikira ndi laser mosavuta, motero kusintha kugawa kwa mphamvu.
Amagwiritsidwa ntchito makamaka polumikiza aluminiyamu ndi magnesium alloys ndi laser, kulumikiza splice ndi lap plate pamagalimoto, laser brazing ndi deep fusion welding.
Mzere wowirikiza ungapezeke ndi ma laser awiri odziyimira pawokha kapena mwa kugawa mzera ndi chogawa mzera.
Miyendo iwiriyi ikhoza kukhala kuphatikiza kwa ma laser okhala ndi mawonekedwe osiyanasiyana a nthawi (pulsed vs. continuous), ma wavelength osiyanasiyana (mid-infrared vs. visible wavelengths) ndi mphamvu zosiyanasiyana, zomwe zingasankhidwe malinga ndi zinthu zenizeni zomwe zakonzedwa.
4. Kuwotcherera kwa Laser Composite
Chifukwa chogwiritsa ntchito kuwala kwa laser ngati gwero lokhalo lotenthetsera, kuwotcherera kwa laser komwe kumachokera ku gwero limodzi lotenthetsera kuli ndi mphamvu yochepa yosinthira komanso kuchuluka kwa kagwiritsidwe ntchito, mawonekedwe a doko la zinthu zosungunulira ndi osavuta kupanga zolakwika, osavuta kupanga ma pores ndi ming'alu ndi zofooka zina, kuti muthetse vutoli, mutha kugwiritsa ntchito mawonekedwe a kutentha kwa magwero ena otenthetsera kuti muwongolere kutentha kwa laser pa workpiece, yomwe nthawi zambiri imatchedwa kuwotcherera kwa laser.
Mtundu waukulu wa laser composite welding ndi composite welding ya laser ndi electric arc, 1 + 1 > 2 effect ndi motere.
pambuyo pa kuwala kwa laser pafupi ndi arc yogwiritsidwa ntchito,kuchuluka kwa ma elekitironi kumachepa kwambiri, mtambo wa plasma wopangidwa ndi laser welding umachepetsedwa, zomwekungathandize kuti kuchuluka kwa kuyamwa kwa laser kukhale kokwera kwambiri, pomwe kutentha kwa arc pa maziko a zinthu kudzawonjezera kuchuluka kwa kuyamwa kwa laser.
2. Kugwiritsa ntchito mphamvu zambiri kwa arc ndi kuchuluka kwa mphamvu zonsekugwiritsa ntchito mphamvu kudzawonjezeka.
3, dera logwirira ntchito la laser ndi laling'ono, losavuta kuyambitsa kusalingana kwa doko lolowetsamo, pomwe kutentha kwa arc ndi kwakukulu, komwe kumathakuchepetsa kusalingana kwa doko lolumikiziraNthawi yomweyo,Ubwino wa kuwotcherera ndi kugwira ntchito bwino kwa arc kumawonjezekachifukwa cha mphamvu ya kuwala kwa laser pa arc yomwe imayang'ana kwambiri komanso kutsogolera.
4, kuwotcherera kwa laser ndi kutentha kwakukulu, malo akuluakulu okhudzidwa ndi kutentha, kuzizira mwachangu komanso liwiro lolimba, zosavuta kupanga ming'alu ndi ma pores; pomwe malo okhudzidwa ndi kutentha kwa arc ndi ang'onoang'ono, zomwe zingachepetse kutentha, kuzizira, liwiro lolimba,imatha kuchepetsa ndikuchotsa kupanga kwa ma pores ndi ming'alu.
Pali mitundu iwiri yodziwika bwino ya laser-arc composite welding: laser-TIG composite welding (monga momwe tawonetsera pansipa) ndi laser-MIG composite welding.
Palinso mitundu ina ya kuwotcherera monga laser ndi plasma arc, laser ndi inductive heat source compound welding.
Zokhudza MavenLaser
Maven Laser ndi mtsogoleri wa ntchito zopanga laser ku China komanso wopereka njira zodziwika bwino zokonzera laser padziko lonse lapansi. Timamvetsetsa bwino momwe makampani opanga zinthu amagwirira ntchito, nthawi zonse timawonjezera zinthu zathu ndi mayankho athu, timalimbikira kufufuza kuphatikiza kwa automation, infoization ndi luntha ndi makampani opanga zinthu, timapereka zida zowotcherera laser, zida zolembera laser, zida zoyeretsera laser ndi zida zodulira zodzikongoletsera zagolide ndi siliva za laser m'mafakitale osiyanasiyana kuphatikiza mndandanda wamagetsi, ndikukulitsa mphamvu zathu nthawi zonse pazida za laser.
