Kuwotcherera kwa laser kungakhale msika womwe ukukula mwachangu kwambiri wogwiritsa ntchito laser

M'zaka zingapo zapitazi, zida zodulira zitsulo pogwiritsa ntchito ma fiber laser zinakula mofulumira, ndipo zinachepa mu 2019. Masiku ano, makampani ambiri akuyembekeza kuti zida za 6KW kapena kupitirira 10KW zidzagwiritsanso ntchito njira yatsopano yodulira laser.

M'zaka zingapo zapitazi, kuwotcherera kwa laser sikunakope chidwi chachikulu. Chimodzi mwa zifukwa zake ndichakuti kukula kwa msika wa makina owotcherera a laser sikunakwere, ndipo n'kovuta kuti makampani ena omwe akuchita nawo kuwotcherera kwa laser akule. Komabe, m'zaka zaposachedwa, chifukwa cha kuchuluka kwa kufunikira kwa kuwotcherera kwa laser m'magawo angapo akuluakulu monga magalimoto, mabatire, kulumikizana kwa kuwala, kupanga zamagetsi, ndi chitsulo, kukula kwa msika wowotcherera wa laser kwawonjezeka pang'onopang'ono. Zikumveka kuti kukula kwa msika wowotcherera wa laser mdziko lonse ndi pafupifupi 11 biliyoni RMB pofika chaka cha 2020, ndipo gawo lake pakugwiritsa ntchito laser lawonjezeka pang'onopang'ono.

Kugwiritsa ntchito kwakukulu kwa laser welding

Laser imagwiritsidwa ntchito powotcherera osati mochedwa kuposa kudula, ndipo mphamvu yaikulu ya makampani akale a laser m'dziko langa ndi kuwotcherera laser. Palinso makampani omwe amagwira ntchito yowotcherera laser m'dziko langa. Kale, laser yopompedwa ndi nyali ndi YAG laser welding zinkagwiritsidwa ntchito kwambiri. Zonse zinali zowotcherera laser zachikhalidwe zomwe sizinkagwiritsidwa ntchito kwambiri. Zinkagwiritsidwa ntchito m'magawo angapo monga nkhungu, zilembo zotsatsa, magalasi, zodzikongoletsera, ndi zina zotero. Kukula kwake kuli kochepa kwambiri. M'zaka zaposachedwa, chifukwa cha kusintha kosalekeza kwa mphamvu ya laser, chofunika kwambiri, ma semiconductor lasers ndi ma fiber lasers pang'onopang'ono apanga zochitika zogwiritsira ntchito laser welding, zomwe zaswa malire oyamba aukadaulo wowotcherera laser ndikutsegula malo atsopano pamsika.

Malo owunikira a fiber laser ndi ochepa, omwe si oyenera kuwotcherera. Komabe, opanga amagwiritsa ntchito mfundo ya galvanometer swing beam ndi ukadaulo monga swing welding head, kuti fiber laser ikwanitse kuwotcherera bwino. Kuwotcherera kwa laser kwalowa pang'onopang'ono m'mafakitale apamwamba am'nyumba monga magalimoto, sitima zapamtunda, ndege, mphamvu ya nyukiliya, magalimoto atsopano amphamvu, ndi kulumikizana kwa kuwala. Mwachitsanzo, FAW, Chery, ndi Guangzhou Honda aku CHINA agwiritsa ntchito mizere yopanga yowotcherera ya laser yokha; CRRC Tangshan Locomotives, CRRC Qingdao Sifang locomotive imagwiritsanso ntchito ukadaulo wowotcherera wa kilowatt-level; mabatire ambiri amphamvu amagwiritsidwa ntchito, ndipo makampani otsogola monga CATL, AVIC Lithium Battery, BYD, ndi Guoxuan agwiritsa ntchito zida zowotcherera za laser zambiri.

Kuwotcherera mabatire amagetsi pogwiritsa ntchito laser kuyenera kukhala chinthu chofunikira kwambiri pa ntchito yowotcherera m'zaka zaposachedwa, ndipo kwalimbikitsa kwambiri makampani monga Lianying Laser, ndi Han's New Energy. Kachiwiri, kuyenera kukhala kuwotcherera matupi ndi ziwalo zamagalimoto. China ndiye msika waukulu kwambiri wamagalimoto padziko lonse lapansi. Pali makampani ambiri akale amagalimoto, makampani atsopano amagalimoto akutuluka nthawi zonse, okhala ndi mitundu pafupifupi 100 yamagalimoto, ndipo kuchuluka kwa kugwiritsa ntchito laser pakuwotcherera popanga magalimoto kudakali kochepa kwambiri. Pali malo ambiri amtsogolo. Chachitatu ndi kugwiritsa ntchito laser pakuwotcherera zamagetsi. Pakati pawo, malo ogwirira ntchito okhudzana ndi kupanga mafoni am'manja ndi kulumikizana kwa kuwala ndi akulu.

Ndikoyeneranso kunena kuti kuwotcherera kwa laser yogwira ntchito ndi manja kwafika pamlingo wovuta kwambiri. Kufunika kwa zida zowotcherera zogwira ntchito ndi manja zochokera ku ma watts 1000 mpaka ma watts 2000 a fiber lasers kwawonjezeka kwambiri m'zaka ziwiri zapitazi. Zitha kulowa m'malo mwa njira yachikhalidwe yowotcherera arc komanso njira yochepetsera mphamvu ya malo. Imagwiritsidwa ntchito kwambiri powotcherera mafakitale a hardware, zida zachitsulo, mapaipi achitsulo chosapanga dzimbiri, zitsulo zotayidwa, zitseko ndi mawindo, njanji, ndi zida za m'bafa. Kuchuluka kwa katundu chaka chatha kunali mayunitsi opitilira 10,000, zomwe sizikufika pachimake, ndipo pakadalibe kuthekera kwakukulu kopanga.

Kuthekera kwa kuwotcherera kwa laser

Kuyambira mu 2018, kukula kwa msika wa laser welding application kwakula mofulumira, ndi avareji ya pachaka yoposa 30%, yomwe yapitirira kukula kwa laser cutting applications. Ndemanga kuchokera ku makampani ena a laser ndi zomwezo. Mwachitsanzo, chifukwa cha mliriwu mu 2020, malonda a Raycus Laser a lasers for welding applications adakwera ndi 152% chaka ndi chaka; RECI Laser idayang'ana kwambiri ma lasers opangidwa ndi manja, ndipo idatenga gawo lalikulu kwambiri m'munda uno.

Malo olumikizira magetsi amphamvu kwambiri ayambanso kugwiritsa ntchito pang'onopang'ono magetsi apakhomo, ndipo chiyembekezo cha kukula n'chokulirapo. M'mafakitale monga kupanga mabatire a lithiamu, kupanga magalimoto, mayendedwe a sitima, ndi kupanga zombo, kuwotcherera kwa laser, monga cholumikizira chofunikira pakupanga, kwabweretsanso mwayi wabwino wopititsa patsogolo chitukuko. Ndi kusintha kosalekeza kwa magwiridwe antchito a laser apakhomo komanso kufunikira kwa kupanga kwakukulu kuti achepetse ndalama, mwayi wa laser wapakhomo wolowa m'malo mwa zinthu zotumizidwa kunja wabwera.

Malinga ndi ntchito zowotcherera, kufunikira kwa mphamvu kuyambira ma watts 1,000 mpaka ma watts 4,000 ndiko kwakukulu kwambiri, ndipo kudzalamulira pakuwotcherera kwa laser mtsogolo. Kuwotcherera kwa laser kochuluka komwe kumagwiridwa ndi manja kumagwiritsidwa ntchito powotcherera zigawo zachitsulo ndi zitsulo zosapanga dzimbiri zokhala ndi makulidwe osakwana 1.5mm, ndipo mphamvu ya 1000W ndi yokwanira. Powotcherera ma casing a aluminiyamu a mabatire amphamvu, mabatire a mota, zida zamlengalenga, matupi agalimoto, ndi zina zotero, 4000W ikhoza kukwaniritsa zosowa zambiri. Kuwotcherera kwa laser kudzakhala gawo logwiritsira ntchito laser lomwe likukula mwachangu mtsogolo, ndipo kuthekera kwakukulu kwa chitukuko kungakhale kwakukulu kuposa kudula kwa laser.
