Gukomeza Umuhengeri
CW, impfunyapfunyo ya "Gukomeza Umuhengeri," bivuga sisitemu ya laser ishoboye gutanga umusaruro wa laser udahagarara mugihe cyo gukora. Kurangwa nubushobozi bwabo bwo gusohora lazeri ubudahwema kugeza ibikorwa birangiye, laseri ya CW itandukanijwe nimbaraga zabo zo hasi nimbaraga zo hejuru ugereranije nubundi bwoko bwa lazeri.
Byagutse-Porogaramu
Bitewe nuburyo bukomeza bwo gusohora ibintu, laseri ya CW isanga ikoreshwa cyane mumirima nko gukata ibyuma no gusudira umuringa na aluminium, bigatuma uboneka mubwoko busanzwe kandi bukoreshwa cyane. Ubushobozi bwabo bwo gutanga ingufu zihamye kandi zihamye zitanga agaciro ntangarugero haba mugutunganya neza no kubyara umusaruro.
Ibikorwa byo Guhindura Ibikorwa
Guhindura laser ya CW kugirango ikore neza inzira ikubiyemo kwibanda kubintu byinshi byingenzi, harimo imbaraga zumurongo wamashanyarazi, umubare wa defocus, diameter ya beam, hamwe n umuvuduko wo gutunganya. Kuringaniza neza ibyo bipimo nibyingenzi kugirango tugere ku musaruro mwiza wo gutunganya, kwemeza imikorere nubuziranenge mubikorwa byo gutunganya laser.
Igishushanyo Cyimbaraga cya Laser Igishushanyo
Ikwirakwizwa ry'ingufu Ibiranga
Ikiranga ikintu cyihariye cya CW ni ukwirakwiza ingufu za Gaussiya, aho gukwirakwiza ingufu za lazeri yambukiranya igice bigabanuka kuva hagati ugana hanze muburyo bwa Gaussiya (gukwirakwiza bisanzwe). Ikwirakwizwa riranga CW laseri kugera kumurongo wo hejuru wibanda kumurongo no gutunganya neza, cyane cyane mubisabwa bisaba kohereza ingufu.
Igishushanyo cyo gukwirakwiza ingufu za CW Laser
Ibyiza bya Wave ikomeza (CW) Laser Welding
Icyerekezo cya Microstructural
Gusuzuma microstructure yibyuma byerekana ibyiza bitandukanye bya lazeri ikomeza ya Wave (CW) yo gusudira hejuru ya Quasi-Continuous Wave (QCW) pulse yo gusudira. QCW isudira yo gusudira, igabanywa ninshuro zayo, mubisanzwe hafi 500Hz, ihura nubucuruzi hagati yikigereranyo cyimbitse hamwe nubujyakuzimu. Igipimo gito cyo guhuzagurika gitera ubujyakuzimu budahagije, mugihe igipimo kinini cyo hejuru kigabanya umuvuduko wo gusudira, kugabanya imikorere. Ibinyuranyo, CW laser yo gusudira, binyuze muguhitamo diameter ikwiye ya diametre hamwe no gusudira imitwe, igera kubudozi bwiza kandi buhoraho. Ubu buryo bugaragaza ko bwizewe cyane mubisabwa bisaba kashe yo hejuru.
Ibitekerezo byubushyuhe
Urebye ingaruka ziterwa nubushyuhe, QCW pulse laser yo gusudira ifite ikibazo cyo guhuzagurika, biganisha ku gushyushya inshuro nyinshi. Ibi birashobora kwerekana itandukaniro riri hagati ya microstructure yicyuma nibikoresho byababyeyi, harimo gutandukana mubunini bwa dislocation hamwe nigipimo cyo gukonjesha, bityo bikongera ibyago byo guturika. Ku rundi ruhande, gusudira CW laser, birinda iki kibazo mugutanga uburyo bumwe bwo gukomeza gushyuha.
Kuborohereza Guhindura
Kubijyanye no gukora no guhinduranya, QCW laser yo gusudira isaba guhuza neza ibipimo byinshi, harimo inshuro zisubiramo inshuro nyinshi, imbaraga zimpanuka, ubugari bwimisemburo, inzinguzingo, nibindi byinshi. CW laser yo gusudira yoroshya inzira yo guhindura, yibanda cyane cyane kumiterere yumurongo, umuvuduko, imbaraga, hamwe na defocus, byoroshe cyane ingorane zikorwa.
Iterambere ry'ikoranabuhanga muri CW Laser Welding
Mugihe QCW laser yo gusudira izwiho imbaraga nyinshi zo hejuru no kwinjiza ubushyuhe buke, bigira akamaro mu gusudira ibice byangiza ubushyuhe nibikoresho bikikijwe cyane, gutera imbere mu buhanga bwo gusudira CW laser, cyane cyane kubukoresha ingufu nyinshi (mubisanzwe hejuru ya watt 500) kandi gusudira byimbitse gusudira bishingiye ku ngaruka zifunguzo, byaguye cyane uburyo bwo gukoresha no gukora neza. Ubu bwoko bwa lazeri burakwiriye cyane cyane kubikoresho bifite uburebure burenze 1mm, bigera ku kigereranyo cyo hejuru (hejuru ya 8: 1) nubwo hashyizwemo ubushyuhe bwinshi.
Quasi-Ikomeza Umuhengeri (QCW) Gusudira Laser
Ikwirakwizwa ryingufu
QCW, ihagaze kuri "Quasi-Ikomeza Umuhengeri," yerekana ikoranabuhanga rya laser aho laser itanga urumuri muburyo budahagarara, nkuko bigaragara mumashusho a. Bitandukanye nogukwirakwiza ingufu zingana zuburyo bumwe bukomeza laseri, laseri ya QCW yibanda kumbaraga zabo cyane. Ibiranga biha QCW laseri yingufu zisumba izindi, bisobanura mubushobozi bukomeye bwo kwinjira. Ingaruka za metallurgical zisa nishusho ya "umusumari" ifite igipimo kinini cyimbitse-y'ubugari, ituma lazeri ya QCW iba indashyikirwa mubikorwa birimo ibibyimba byerekana cyane, ibikoresho byangiza ubushyuhe, hamwe na micro-gusudira neza.
Kongera imbaraga no kugabanya Plume Kwivanga
Kimwe mu byiza bigaragara byo gusudira QCW laser ni ubushobozi bwayo bwo kugabanya ingaruka ziterwa nicyuma ku gipimo cyo kwinjiza ibintu, biganisha ku nzira ihamye. Mugihe cyo gukorana kwa laser-material, guhumeka cyane birashobora gukora uruvange rwumuyaga wibyuma na plasma hejuru yicyuzi gishonga, bakunze kwita icyuma. Iyi plume irashobora gukingira ubuso bwibikoresho kuri lazeri, bigatera amashanyarazi adahungabana hamwe nudusembwa nka spatter, ahantu haturika, nibyobo. Nyamara, imyuka isohoka rimwe na rimwe ya lazeri ya QCW (urugero, 5m yaturitse ikurikirwa no guhagarara 10ms) iremeza ko buri musemburo wa lazeri ugera hejuru yibikoresho bitagize ingaruka ku cyuma, bikavamo uburyo bwo gusudira butajegajega, cyane cyane bufite akamaro ko gusudira.
Ikidendezi gihamye
Imbaraga za pisine yashonga, cyane cyane mubijyanye nimbaraga zikora kuri urufunguzo, ni ngombwa muguhitamo ubwiza bwa weld. Lazeri ikomeza, bitewe nigihe kirekire imara hamwe na zone nini yibasiwe nubushyuhe, ikunda gukora ibidendezi binini byuzuyemo ibyuma byamazi. Ibi birashobora kuganisha ku nenge zijyanye n'ibidendezi binini bishonga, nk'isenyuka. Ibinyuranye, ingufu zibanze hamwe nigihe gito cyo gukorana kwa QCW laser yo gusudira yibanda kuri pisine yashonga ikikije urufunguzo, bikavamo gukwirakwiza imbaraga imwe hamwe no kugabanuka gukabije, guturika, no gutatana.
Agace kagabanutse Ubushyuhe (HAZ)
Gukomeza laser yo gusudira ibikoresho kubushyuhe burambye, biganisha kumashanyarazi akomeye mubintu. Ibi birashobora gutera ihindagurika ryubushyuhe hamwe nubusembwa buterwa no guhangayika mubikoresho bito. Lazeri ya QCW, hamwe nibikorwa byayo rimwe na rimwe, yemerera ibikoresho igihe cyo gukonja, bityo bikagabanya zone yibasiwe nubushyuhe hamwe nubushyuhe bwinjiza. Ibi bituma QCW laser yo gusudira ikwiranye cyane nibikoresho bito hamwe nibice byangiza ubushyuhe.
Imbaraga Zisumbuye
Nubwo ifite imbaraga zingana nkizikomeza, lazeri ya QCW igera kumurengera mwinshi hamwe nubucucike bwingufu, bikavamo kwinjira cyane hamwe nubushobozi bukomeye bwo gusudira. Iyi nyungu igaragara cyane cyane mu gusudira umuringa na aluminium alloys. Ibinyuranyo, lazeri zihoraho zifite imbaraga zingana zishobora kunanirwa gukora ikimenyetso hejuru yibikoresho bitewe nubucucike buke, biganisha ku gutekereza. Imbaraga nyinshi zikomeza lazeri, nubwo zishobora gushonga ibikoresho, zirashobora kwiyongera cyane mubipimo byo kwinjiza nyuma yo gushonga, bigatera ubujyakuzimu budashobora kugenzurwa no kwinjiza ubushyuhe, bidakwiriye gusudira amashuka mato kandi bishobora kuvamo nta kimenyetso cyangwa gutwika -kugenda, kunanirwa kuzuza ibisabwa mubikorwa.
