Kafushane, i-laser welding inikezela ngesivinini esikhulu, imiphumela yekhwalithi ephezulu ngokuhlanekezela okuncane.
Ivumelana nezimo kunhlobonhlobo yezinto zokwakha futhi ingalungiswa ukuze ihlangabezane nezidingo ezithile zohlelo ngalunye.
Enye yezinzuzo ezinkulu ze-laser welding ukuguquguquka kwayo.
Ingasetshenziselwa ukushisela hhayi kuphela izinsimbi ezifana ne-aluminium, ithusi, nensimbi engagqwali kodwa nohlu lwezinye izinto.
Kubandakanya ama-thermoplastics athile, izibuko, nezinhlanganisela.
Lokhu kuyenza ibe wusizo ezimbonini ezihlukahlukene, kusukela ekukhiqizeni izimoto kuya kwezobuchwepheshe kanye nokukhiqizwa kwemishini yezokwelapha.
Iyini i-Laser Welding? [Ingxenye 2]
Ukumelwa Kwekusasa Eliphambili
I-laser welding ubuchwepheshe obusezingeni eliphezulu obusebenzisa i-laser enamandla amakhulu ukuze kuhlanganiswe ngokunembile izinto, ngokuvamile izinsimbi, ngokuzincibilikisa lapho kuxhunywana khona.
Le nqubo idala isibopho esiqinile, esiqinile esinokuguqulwa okuncane uma kuqhathaniswa nezindlela zendabuko zokushisela.
Iyashesha, iyasebenza, futhi iyakwazi ukukhiqiza imiphumela yekhwalithi ephezulu.
Inhliziyo ye-Laser Welding
Enhliziyweni ye-laser welding kukhona i-laser beam ngokwayo, ekhiqiza ukushisa okukhulu.
Lapho i-laser igxile endaweni yensimbi, incibilikisa impahla, yakhe ichibi elincane elincibilikisiwe.
Leli chibi liqina ngokushesha, ngokuvamile phakathi kwama-millisecond, uma i-laser isuka, okuholela ekuxhumekeni okuqinile phakathi kwezingxenye.
Inqubo ilawulwa kakhulu, okusho ukuthi izindawo ezishiselwe kuphela ezithintekayo, okushiya konke okunye okungathinteki kakhulu.
Ukuqonda Laser Welding
Indlela elula yokuqonda ukushisela nge-laser ukucabanga ngengilazi ekhulisayo egxilisa imisebe yelanga endaweni encane.
Njengoba nje ukukhanya okugxilile kungancibilikisa ucezu lwephepha, i-laser beam igxilisa amandla amakhulu endaweni yensimbi.
Ukuyibangela ukuba incibilike futhi, kwezinye izimo, ize ihwamuke.
Amandla Density of Laser Beam Welding
Amandla e-laser akalwa ngokuya ngokuminyana kwamandla.
Okuphakeme ngendlela emangalisayo—ukufinyelela izigidi zamawathi ngesentimitha yesikwele.
Lapho amandla e-laser ekhudlwana, inqubo yokushisela ingaba ngokushesha, futhi lapho ukushisa kungangena kuzinto ezibonakalayo.
Kodwa-ke, amandla aphezulu e-laser nawo anyusa izindleko zemishini.
Ukwenza kube yisici esibalulekile uma ucubungula izindleko zizonke zomshini.

Ukubenza baphumelele kakhulu ezinhlobonhlobo zemisebenzi yokushisela.
Enye yezinzuzo ezinkulu zama-fiber lasers yikhono lawo lokukhiqiza nokuqondisa i-laser beam ngentambo ye-fiber optic.
Lokhu kuvumela ikhwalithi ephezulu ye-beam, ukunemba okukhuphukile, kanye nokuminyana kwamandla okuphezulu, okuholela ekujuleni kokungena okuhle lapho kushiselwa.
Ukwengeza, ama-laser e-fiber anokusetshenziswa okuncane kwezinto ezisetshenziswayo, ehlisa izindleko zokuyilungisa nokuba yinkimbinkimbi.
Angabuye ahlanganiswe kalula namarobhothi noma imishini ye-CNC, ayenze ibe nezinto ezihlukahlukene kakhulu kuzilungiselelo zezimboni.
Enye inzuzo ukuthi akukho mkhawulo emandleni we-fiber lasers, okwenza i-welding esebenza kahle kakhulu ngisho nasezintweni eziwugqinsi.
I-CO2 Laser: Ilungele Izicelo Ezithile
Amalaser e-CO2 awuhlobo lokuqala lwelaser olusetshenziselwa ukushisela i-laser yezimboni futhi asasetshenziswa kwezinye izinhlelo zokusebenza.
Lawa ma-laser akhipha i-laser esekelwe kugesi engakwazi ukuqondiswa nge-fiber optics.
Okuholela kukhwalithi ephansi ye-beam uma kuqhathaniswa nama-fiber lasers.
Lokhu kubenza bangaqondile kangako kwezinye izinhlelo zokusebenza zokushisela.
Amalaser e-CO2 ngokuvamile asetshenziselwa ukushisela izingcezu zokusebenza eziyindilinga ngoba i-laser ingamiswa endaweni kuyilapho ucezu lokusebenza luzungeza.
Kodwa-ke, zidinga ukunakekelwa okwengeziwe ngenxa yesidingo esivamile sezinto ezisetshenziswayo njengezibuko namagesi.
Ngokusebenza kahle kwamandla okumaphakathi okungama-20%, amalaser e-CO2 awawongi amandla njengamalaser efiber.
Okuholela ezindlekweni zokusebenza eziphezulu.
I-Nd:I-YAG Laser: Ifakazelwe Ngemikhawulo
I-Nd:YAG (i-Neodymium-doped Yttrium Aluminium Garnet) amalaser angubuchwepheshe obufakazelwe ekushiseleni nge-laser.
Kodwa beza nokulinganiselwa okuthile.
Basebenzisa amandla aphansi, ngokuvamile acishe abe ngu-5%.
Okuholela ezinkingeni zokuphatha ezishisayo kanye nezindleko zokusebenza eziphezulu.
Enye yamandla e-Nd:YAG lasers yikhono lawo lokuqondisa i-laser beam isebenzisa i-fiber optics, ethuthukisa ikhwalithi ye-beam.
Kodwa-ke, kusenzima ukugxilisa i-laser beam endaweni encane, ukukhawulela ukunemba kwayo ezinhlelweni ezithile.
Nd:Amalaser e-YAG avame ukusetshenziselwa imisebenzi ethile efana nokulungisa isikhunta, lapho ukugxila okukhulu kwamukelekile.
Futhi banezindleko eziphezulu zokunakekela, njengoba izinto ezisetshenziswayo njengezibuko namalambu zidinga ukushintshwa njalo.
I-Diode Laser: Kunzima Ukugxila Ngenxa Yekhwalithi Ebi Ye-Beam
Amalaser e-Diode avame kakhulu ezinhlelweni ezidinga ukusebenza kahle kwamandla (cishe u-40%).
Lokhu kusebenza kahle okuphezulu kuholela ekuphathweni okungcono kwe-thermal kanye nezindleko eziphansi zokusebenza uma kuqhathaniswa nezinye izinhlobo ze-laser.
Kodwa-ke, enye yezinkinga ezinkulu zama-lasers e-diode ukuthi ikhwalithi yawo ye-boam iphansi kakhulu.
Okwenza kube nzima ukugxilisa i-laser kusayizi wendawo encane.
Lokhu kunciphisa ukunemba kwazo kwezinye izinhlelo zokusebenza zokushisela.
Ngaphandle kwalokhu, ama-laser e-diode asawusizo ezintweni ezithile, ikakhulukazi amapulasitiki, futhi angasetshenziswa ngempumelelo kulezo zinhlelo zokusebenza.
Ufuna Ukuqalisa Ngomshini Welding Ophathwayo We-Fiber Laser?
I-Conduction & Keyhole Laser Welding
Ukuqonda I-Common Welding Technique
I-laser welding ingahlukaniswa ngezinhlobo ezimbili eziyinhloko: i-welding conduction kanye ne-keyhole welding.
Lezi zinqubo ezimbili ziyehluka endleleni i-laser esebenzisana ngayo nezinto kanye nemiphumela ezikhiqizayo.
Umehluko Obalulekile
Ikhwalithi yokushisela
I-Conduction welding ngokuvamile ikhiqiza imiphumela ehlanzekile ene-spatter encane kanye nokukhubazeka okumbalwa, kuyilapho ukushisela kwe-keyhole kungase kubangele isipatter esiningi, i-porosity, kanye nendawo enkulu ethinteke ekushiseni.
Ukusabalalisa Ukushisa Kwe-Welding
I-Conduction welding isakaza ukushisa ngokulinganayo kuzo zonke izinhlangothi, kuyilapho ukushisela kwe-keyhole kugxilisa ukushisa endaweni encane, eqondile, okuholela ekungeneni okujulile.
Isivinini sokushisela
I-Keyhole welding iyashesha, iyenza ifanelekele ukukhiqizwa kwevolumu ephezulu, kuyilapho i-conduction welding ihamba kancane kodwa inikeza ukunemba okwengeziwe.
I-Welding yokuqhuba
I-Conduction welding iyinqubo ethambile futhi ehamba kancane. Ngale ndlela, ugongolo lwe-laser luncibilikisa ingaphezulu lensimbi.
Ukubangela ukuthi insimbi ifinyelele izinga lokushisa layo lokuhlangana (iphuzu lapho iphenduka ibe uketshezi).
Kodwa ungadluleli ngalé kwalokho kumazinga okushisa okuhwamuka (lapho insimbi ingaphenduka igesi).
Ukushisa kusakazwa ngokulinganayo kuyo yonke into, okusho ukuthi ukudluliswa kokushisa kwenzeka kuzo zonke izinhlangothi ngaphakathi kwensimbi.
Ngoba i-conduction welding iyancibilika kancane kancane, ikhiqiza imiphumela yekhwalithi ephezulu.
Lokhu kufaka i-spatter encane (amaconsi amancane ezinto ezincibilikisiwe ezingaphuma ngesikhathi sokushisela) kanye nentuthu ephansi, okwenza inqubo ihlanzeke.
Kodwa-ke, ngenxa yokuthi ihamba kancane, i-conduction welding ijwayele ukusetshenziselwa izinhlelo zokusebenza ezidinga ukunemba kanye namajoyinti ekhwalithi ephezulu kunejubane.
I-Keyhole Welding
I-Keyhole welding, ngakolunye uhlangothi, inqubo esheshayo futhi enolaka.
Ngale ndlela, i-laser beam iyancibilika futhi ihwamulise insimbi, idale imbobo encane, ejulile noma imbobo kakhiye endabeni.
Ukushisa okukhulu kwe-laser kubangela ukuthi insimbi ifinyelele kokubili izinga lokushisa layo lokuhlanganisa kanye nezinga lokushisa lokuhwamuka.
Ngelinye lamachibi ancibilikisiwe aphenduka igesi.
Ngenxa yokuthi i-material is vaporized, ukushisa kudluliselwa ngaphezulu kwe-perpendicular ku-laser beam, okuholela echibini lokushisela elijulile, elincane.
Le nqubo ishesha kakhulu kune-welding conduction, iyenza ibe ilungele imigqa yokukhiqiza enevolumu ephezulu.
Kodwa-ke, ukushisa okusheshayo nokushubile kungabangela i-spatter, futhi ukuncibilika okusheshayo kungaholela e-porosity (amabhamuza amancane egesi avaleleke ngaphakathi kwe-weld).
Kanye nendawo enkulu ethinteke ekushiseni (HAZ) (indawo ezungeze i-weld eshintshwa ukushisa).
