Ukushisela kuyinqubo yokuhlanganisa izinsimbi ezimbili noma ngaphezulu ndawonye ngokusebenzisa ukushisa. Ukushisela ngokuvamile kuhilela ukushisa into endaweni yayo yokuncibilika ukuze isisekelo sensimbi sincibilike ukuze kugcwaliswe izikhala phakathi kwamalunga, kwakhe ukuxhumana okuqinile. I-laser welding iyindlela yokuxhumana esebenzisa i-laser njengomthombo wokushisa.
Thatha ikesi eliyisikwele lebhethri lamandla njengesibonelo: umgogodla webhethri uxhunywe nge-laser ngokusebenzisa izingxenye eziningi. Phakathi nayo yonke inqubo yokushisela nge-laser, amandla okuxhuma izinto ezibonakalayo, ukusebenza kahle kokukhiqiza, kanye nezinga elingasebenzi kahle yizindaba ezintathu imboni ekhathazeke kakhulu ngazo. Amandla okuxhumana okubalulekile angaboniswa ukujula nobubanzi bokungena kwe-metallographic (okuhlobene eduze nomthombo wokukhanya we-laser); ukusebenza kahle kokukhiqiza kuhlobene kakhulu namandla okucubungula omthombo wokukhanya we-laser; izinga lesici lihlobene ikakhulukazi nokukhethwa komthombo wokukhanya we-laser; ngakho-ke, lesi sihloko sixoxa ngezinto ezivamile emakethe. Ukuqhathanisa okulula kwemithombo yokukhanya ye-laser eminingana kwenziwa, ngethemba lokusiza abanye abathuthukisi bezinqubo.
Ngobalaser weldingempeleni kuyinqubo yokuguqula ukukhanya kuya ekushiseni, imingcele eminingana ebalulekile ehilelekile ilandelayo: ikhwalithi ye-beam (i-BBP, i-M2, i-angle yokuhlukana), ubukhulu bamandla, ububanzi obuyisisekelo, ifomu lokusabalalisa amandla, ikhanda lokushisela eliguquguqukayo, ukucubungula amafasitela wenqubo nezinto ezilungisekayo. zisetshenziselwa kakhulu ukuhlaziya nokuqhathanisa imithombo yokukhanya ye-laser kusuka kulezi zikhombisi-ndlela.
I-Singlemode-Multimode Laser Comparison
Incazelo yemodi eyodwa yemodi eyodwa:
Imodi eyodwa isho iphethini yokusabalalisa eyodwa yamandla e-laser endizeni enezinhlangothi ezimbili, kuyilapho imodi eminingi isho iphethini yokusabalalisa amandla yendawo eyakhiwe ukuphakama okuphezulu kwamaphethini wokusabalalisa amaningi. Ngokuvamile, usayizi wekhwalithi ye-M2 factor ungasetshenziswa ukwahlulela ukuthi ukuphuma kwe-fiber laser kuyimodi eyodwa noma imodi eminingi: I-M2 engaphansi kuka-1.3 iyilaser yemodi eyodwa ehlanzekile, i-M2 ephakathi kuka-1.3 no-2.0 iyi-quasi- I-laser yemodi eyodwa (imodi embalwa), futhi i-M2 inkulu kuno-2.0. Okwe-laser ye-multimode.

Okwe-laser ye-multimode.
Njengoba kuboniswe emfanekisweni: Umfanekiso b ubonisa ukusatshalaliswa kwamandla kwemodi eyodwa eyisisekelo, futhi ukusatshalaliswa kwamandla kunoma iyiphi indlela edlula phakathi nendawo yendilinga kusesimweni sejika le-Gaussian. Isithombe a sibonisa ukusatshalaliswa kwamandla ezinhlobo eziningi, okuwukusatshalaliswa kwamandla kwendawo okwakhiwa ukugxumela phezulu kwamamodi e-laser eyodwa. Umphumela we-multi-mode superposition ijika eliyisicaba.
Amalaser ajwayelekile emodi eyodwa: IPG YLR-2000-SM, SM isifinyezo seModi Eyodwa. Izibalo zisebenzisa i-collimated focus 150-250 ukuze kubalwe usayizi wendawo okugxilwe kuyo, ukuminyana kwamandla ngu-2000W, futhi ukuminyana kwamandla okugxilile kusetshenziselwa ukuqhathanisa.
Ukuqhathaniswa kwemodi eyodwa kanye nemodi eminingilaser weldingimiphumela
I-laser yemodi eyodwa: ububanzi obuncane bomgogodla, ukuminyana kwamandla aphezulu, amandla okungena aqinile, indawo encane ethinteke ukushisa, efana nommese obukhali, ofaneleka ikakhulukazi ukushisela amapuleti amancane kanye nokushisela ngesivinini esikhulu, futhi ingasetshenziswa nama-galvanometers ukucubungula amancane. izingxenye nezingxenye ezikhanya kakhulu (izingxenye ezibonisa kakhulu) izindlebe, izingcezu ezixhumayo, njll.), njengoba kuboniswe emfanekisweni ongenhla, imodi eyodwa inembobo kakhiye encane kanye nevolumu elinganiselwe yomhwamuko wensimbi wangaphakathi wokucindezela okuphezulu, ngakho ngokuvamile ayinawo. babe nezici ezifana nezimbotshana zangaphakathi. Ngesivinini esiphansi, ukubukeka kuba nzima ngaphandle kokuvunguza umoya ovikelayo. Ngezivinini eziphezulu, ukuvikeleka kuyengezwa. Izinga lokucubungula igesi lihle, ukusebenza kahle kuphezulu, ama-welds abushelelezi futhi ayisicaba, futhi izinga lokukhiqiza liphezulu. Ilungele ukushisela isitaki kanye ne-welding yokungena.
I-laser enemodi eminingi: Ububanzi obukhulu obuyingqikithi, ukuminyana kwamandla okuphansi kancane kune-laser yemodi eyodwa, ummese ongacacile, imbobo kakhiye enkulu, isakhiwo sensimbi esishubile, isilinganiso esincane sokujula kuya kobubanzi, futhi ngamandla afanayo, ukujula kokungena kungaphansi ngo-30%. kunaleyo ye-laser yemodi eyodwa, ngakho ifanele ukusetshenziswa Ifanele ukucutshungulwa kwe-butt weld kanye nokucutshungulwa kwepuleti eliwugqinsi elinezikhala ezinkulu zomhlangano.
Inhlanganisela-yendandatho Laser Contrast
I-Hybrid welding: I-semiconductor laser beam ene-wavelength engu-915nm kanye ne-fiber laser beam enobude obungu-1070nm ihlanganiswe ekhanda elifanayo lokushisela. Imishayo emibili ye-laser isatshalaliswa ngokuhlangene futhi izindiza ezigxilile zemishayo emibili ye-laser zingalungiswa kalula, ukuze umkhiqizo ube nakho kokubili i-semiconductor.laser weldingamakhono emva Welding. Umphumela uyagqama futhi unokujula kwefiberlaser welding.
Ama-semiconductors avame ukusebenzisa indawo enkulu yokukhanya engaphezu kuka-400um, okuyiyona enesibopho esikhulu sokushisisa izinto, ukuncibilikisa indawo engaphezulu, kanye nokukhulisa izinga lokumuncwa kwe-fiber laser (izinga lokumuncwa kwe-laser likhuphuka njengoba izinga lokushisa likhuphuka)
I-laser eyindandatho: Amamojula amabili we-fiber laser akhipha ukukhanya kwe-laser, okudluliselwa endaweni ebonakalayo nge-fiber optical eyinhlanganisela (i-fiber optical eyindandatho ngaphakathi kwe-cylindrical optical fiber).
Imishayo ye-laser emibili enendawo yonyaka: iringi yangaphandle inesibopho sokunweba ukuvuleka kwembobo kakhiye nokuncibilikisa impahla, futhi i-laser iringi yangaphakathi inesibopho sokujula kokungena, okuvumela ukushisela kwe-spatter okuphansi kakhulu. Ingaphakathi nengaphandle le-laser power core diameters lingafaniswa ngokukhululekile, futhi ububanzi obuyisisekelo bungafaniswa ngokukhululekile. Iwindi lenqubo liguquguquka kakhulu kunalelo le-laser beam eyodwa.
Ukuqhathaniswa kwemiphumela ye-welding-circular welding
Njengoba i-hybrid welding iyinhlanganisela ye-semiconductor conductivity welding kanye ne-fiber optic deep penetration welding, ukungena kwendandatho yangaphandle akujulile, isakhiwo se-metallographic sibukhali futhi sincane; ngasikhathi sinye, ukubukeka kuyi-conductivity eshisayo, ichibi elincibilikisiwe linokushintshashintsha okuncane, ububanzi obukhulu, futhi ichibi elincibilikisiwe lizinzile, likhombisa ukubukeka okushelelayo.
Njengoba i-laser yendandatho iyinhlanganisela ye-welding yokungena ejulile kanye ne-welding yokungena ejulile, indandatho yangaphandle ingabuye ikhiqize ukujula kokungena, okungakhulisa ngempumelelo ukuvulwa kwembobo yokhiye. Amandla afanayo anokujula okukhulu kokungena kanye ne-metallography eshubile, kodwa ngesikhathi esifanayo, ukuzinza kwechibi elincibilikisiwe kungaphansi kancane kunokuguquguquka kwe-fiber optical semiconductor kukhulu kancane kunokwe-welding eyinhlanganisela, futhi ukugoqa kukhulu uma kuqhathaniswa.
