Ukushisela kuyinqubo yokuhlanganisa izinsimbi ezimbili noma ngaphezulu ndawonye ngokusebenzisa ukushisa. Ukushisela ngokuvamile kuhilela ukufudumeza into kuze kube yilapho incibilika khona ukuze insimbi eyisisekelo incibilike ukuze kugcwaliswe izikhala phakathi kwamalunga, kwakhiwe uxhumano oluqinile. Ukushisela nge-laser kuyindlela yokuxhuma esebenzisa i-laser njengomthombo wokushisa.
Thatha ibhethri lamandla ekheyisi lesikwele njengesibonelo: umongo webhethri uxhunywe yi-laser ngezingxenye eziningi. Phakathi nenqubo yonke yokushisela i-laser, amandla okuxhumeka kwezinto, ukusebenza kahle kokukhiqiza, kanye nezinga elingalungile yizinkinga ezintathu imboni ekhathazeke kakhulu ngazo. Amandla okuxhumeka kwezinto angabonakala ngokujula nobubanzi bokungena kwe-metallographic (okuhlobene eduze nomthombo wokukhanya kwe-laser); ukusebenza kahle kokukhiqiza kuhlobene kakhulu nekhono lokucubungula lomthombo wokukhanya we-laser; izinga lokungalungi lihlobene kakhulu nokukhethwa komthombo wokukhanya we-laser; ngakho-ke, lesi sihloko sixoxa ngezinto ezivamile emakethe. Kuqhathaniswa okulula kwemithombo yokukhanya ye-laser eminingana, ngethemba lokusiza abathuthukisi bezinqubo abakanye nabo.
Ngobaukushisela nge-laserEmpeleni inqubo yokuguqula ukukhanya kube ukushisa, amapharamitha amaningana abalulekile ahilelekile yile: ikhwalithi ye-beam (BBP, M2, i-divergence angle), ubuningi bamandla, ububanzi obuyinhloko, ifomu lokusabalalisa amandla, ikhanda lokushisela eliguquguqukayo, ukucubungula amafasitela enqubo kanye nezinto ezicutshungulwayo zisetshenziswa kakhulu ukuhlaziya nokuqhathanisa imithombo yokukhanya kwe-laser kusuka kulezi zinkomba.
Ukuqhathaniswa kwe-Laser ye-Singlemode-Multimode
Incazelo yemodi eningi yemodi eyodwa:
Imodi eyodwa ibhekisela kuphethini eyodwa yokusabalalisa amandla e-laser endizeni enezinhlangothi ezimbili, kuyilapho imodi eminingi ibhekisela kuphethini yokusabalalisa amandla endawo eyakhiwe ukufakwa kwamaphethini amaningi okusabalalisa. Ngokuvamile, ubukhulu bekhwalithi ye-beam M2 factor bungasetshenziswa ukwahlulela ukuthi umkhiqizo we-fiber laser uyimodi eyodwa noma imodi eminingi: I-M2 engaphansi kuka-1.3 iyi-laser emsulwa yemodi eyodwa, i-M2 ephakathi kuka-1.3 no-2.0 iyi-laser yemodi eyodwa (imodi embalwa), kanti i-M2 inkulu kuno-2.0. Kuma-laser emodi eminingi.

Imodi eyodwa ibhekisela kuphethini eyodwa yokusabalalisa amandla e-laser endizeni enezinhlangothi ezimbili, kuyilapho imodi eminingi ibhekisela kuphethini yokusabalalisa amandla endawo eyakhiwe ukufakwa kwamaphethini amaningi okusabalalisa. Ngokuvamile, ubukhulu bekhwalithi ye-beam M2 factor bungasetshenziswa ukwahlulela ukuthi umkhiqizo we-fiber laser uyimodi eyodwa noma imodi eminingi: I-M2 engaphansi kuka-1.3 iyi-laser emsulwa yemodi eyodwa, i-M2 ephakathi kuka-1.3 no-2.0 iyi-laser yemodi eyodwa (imodi embalwa), kanti i-M2 inkulu kuno-2.0. Kuma-laser emodi eminingi.
Njengoba kuboniswe esithombeni: Isithombe b sibonisa ukusatshalaliswa kwamandla kwemodi eyodwa eyisisekelo, kanti ukusatshalaliswa kwamandla kunoma iyiphi indlela edlula phakathi nendawo yendilinga kusesimweni sejika laseGaussian. Isithombe a sibonisa ukusatshalaliswa kwamandla emodi eminingi, okuwukusatshalaliswa kwamandla endawo okwakhiwa yi-superposition yamamodi amaningi e-laser eyodwa. Umphumela we-superposition yamamodi amaningi uyijika eliyisicaba.
Ama-laser avamile emodi eyodwa: IPG YLR-2000-SM, i-SM yisifinyezo se-Single Mode. Izibalo zisebenzisa i-collimated focus 150-250 ukuze kubalwe usayizi wendawo yokugxila, ubuningi bamandla bungu-2000W, kanti ubuningi bamandla okugxila busetshenziselwa ukuqhathanisa.
Ukuqhathaniswa kwemodi eyodwa kanye nemodi eminingiukushisela nge-laserimiphumela
I-laser yemodi eyodwa: ububanzi obuncane bomgogodla, ukuminyana kwamandla aphezulu, ikhono lokungena eliqinile, indawo encane ethintekile ekushiseni, efana nommese obukhali, ofaneleka kakhulu ekushiseni amapuleti amancane kanye nokushisisa ngesivinini esikhulu, futhi ingasetshenziswa ngama-galvanometer ukucubungula izingxenye ezincane kanye nezingxenye ezikhanyayo kakhulu (izingxenye ezikhanyayo kakhulu) izindlebe, izingcezu ezixhumanisayo, njll.), njengoba kuboniswe esithombeni esingenhla, imodi eyodwa inesikhiye esincane kanye nomthamo olinganiselwe womusi wensimbi wangaphakathi ocindezelwe kakhulu, ngakho ngokuvamile ayinazo iziphambeko ezifana nama-pores angaphakathi. Ngesivinini esiphansi, ukubukeka kuba nzima ngaphandle kokushaya umoya ovikelayo. Ngesivinini esiphezulu, ukuvikelwa kuyangezwa. Ikhwalithi yokucubungula igesi ilungile, ukusebenza kahle kuphezulu, ama-weld abushelelezi futhi ayisicaba, futhi izinga lokukhiqiza liphezulu. Ifaneleka ekushiseni ama-stack kanye nokushisisa ama-penetration.
I-laser yemodi eminingi: Ububanzi obukhulu bomgogodla, ubuningi bamandla obuphansi kancane kune-laser yemodi eyodwa, ummese ongenalutho, imbobo enkulu yokhiye, isakhiwo sensimbi esijiyile, isilinganiso esincane sokujula nobubanzi, futhi ngamandla afanayo, ukujula kokungena kuphansi ngo-30% kunokwe-laser yemodi eyodwa, ngakho-ke kufanelekile ukusetshenziswa. Ifanele ukucutshungulwa kwe-butt weld kanye nokucutshungulwa kwepuleti elijiyile elinezikhala ezinkulu zokuhlangana.
Umehluko we-Laser we-Composite-Ring
Ukushisela okuhlanganisiwe: Ugongolo lwelaser lwe-semiconductor olunobude be-wavelength obungu-915nm kanye nogongolo lwelaser lwe-fiber olunobude be-wavelength obungu-1070nm kuhlanganiswe ekhanda elifanayo lokushisela. Imishayo emibili ye-laser isatshalaliswa ngokulinganayo futhi izindiza ezigxile zemishayo emibili ye-laser zingalungiswa kalula, ukuze umkhiqizo ube ne-semiconductor zombili.ukushisela nge-laseramakhono ngemva kokushisela. Umphumela ukhanya futhi unobubanzi befayibhaukushisela nge-laser.
Ama-semiconductor avame ukusebenzisa indawo enkulu yokukhanya engaphezu kuka-400um, okuyiyona ebangela kakhulu ukushisa izinto kusengaphambili, ukuncibilikisa ubuso bezinto, kanye nokwandisa izinga lokumuncwa kwezinto ze-fiber laser (izinga lokumuncwa kwezinto ze-laser liyakhula njengoba izinga lokushisa likhuphuka)
I-laser yendandatho: Amamojula amabili e-laser yentambo akhipha ukukhanya kwe-laser, okudluliselwa ebusweni bezinto ezibonakalayo ngentambo ye-optical ehlanganisiwe (intambo ye-optical yendandatho ngaphakathi kwentambo ye-optical eyindilinga).
Imisebe emibili ye-laser ene-annular spot: indandatho yangaphandle inesibopho sokwandisa ukuvulwa kwe-keyhole nokuncibilikisa izinto, kanti i-laser yendandatho yangaphakathi inesibopho sokujula kokungena, okuvumela ukushibilika kwe-spatter okuphansi kakhulu. Ububanzi be-core power laser yendandatho yangaphakathi neyangaphandle bungalinganiswa ngokukhululekile, futhi ububanzi be-core bungalinganiswa ngokukhululekile. Iwindi lenqubo liguquguquka kakhulu kunele-laser beam eyodwa.
Ukuqhathaniswa kwemiphumela yokushisela eyindilinga ehlanganisiwe
Njengoba ukushisela okuxubile kuyinhlanganisela yokushisela kokushisa kwe-semiconductor kanye nokushisela kokungena okujulile kwe-fiber optic, ukungena kwendandatho yangaphandle akujulile, isakhiwo se-metallographic sibukhali futhi sincane; ngesikhathi esifanayo, ukubukeka kuwukushisela kokushisa, ichibi elincibilikisiwe linokuguquguquka okuncane, ububanzi obukhulu, futhi ichibi elincibilikisiwe lizinzile kakhudlwana, libonakala libushelelezi.
Njengoba i-laser yendandatho iyinhlanganisela yokushisela okujulile kanye nokushisela okujulile, indandatho yangaphandle ingakhiqiza nokujula kokungena, okungakhulisa ngempumelelo ukuvuleka kwe-keyhole. Amandla afanayo anokujula okukhulu kokungena kanye ne-metallography ejiyile, kodwa ngesikhathi esifanayo, ukuzinza kwechibi elincibilikisiwe kuncane kancane kunokushintshashintsha kwe-optical fiber semiconductor kukhulu kancane kunokwe-composite welding, futhi ubulukhuni bukhulu kakhulu.
