Laser Welding of Copper Materials: Blue Laser VS Green Laser

I-laser welding iyindlela yokucubungula esebenza kahle kakhulu. Inqubo ye-laser machining ingumphumela wokuxhumana phakathi kwe-beam ethile yamandla kanye nempahla. Izinto ezisetshenziswayo ngokuvamile zihlukaniswa ngokwezinsimbi nezingezona izinsimbi. Izinto zensimbi zihlanganisa insimbi, insimbi, ithusi, i-aluminium, nama-alloys ahlobene nayo, kuyilapho izinto ezingezona ezensimbi zifaka ingilazi, ukhuni, ipulasitiki, indwangu, nezinto eziphukayo. Ukukhiqizwa kwe-laser kusetshenziswa ezimbonini eziningi, kodwa kuze kube manje, ukusetshenziswa kwayo ngokuyinhloko kungaphakathi kwalezi zigaba zezinto ezibonakalayo.

Imboni Ye-Laser Idinga Ukuqinisa Ucwaningo Ngempahla Ebalulekile

E-China, ukuthuthuka okusheshayo kwemboni ye-laser kuqhutshwa isidingo esikhulu sokufakwa kwezicelo. Kodwa-ke, abakhiqizi abaningi bemishini ye-laser bagxila kakhulu ekusebenzelaneni phakathi kwe-laser beam nezingxenye zemishini, abanye becabangela ukuzenzekelayo kwemishini. Kunokuntuleka kocwaningo ngezinto ezisetshenziswayo, njengokunquma ukuthi yimiphi imingcele ye-beam elungele izinto ezahlukahlukene. Leli gebe ocwaningweni lisho ukuthi ezinye izinkampani zenza imishini emisha kodwa azikwazi ukuhlola izinhlelo zayo ezintsha. Izinkampani eziningi ze-laser zinonjiniyela be-optical and mechanical kodwa bambalwa onjiniyela besayensi yezinto ezibonakalayo, okugqamisa isidingo esiphuthumayo socwaningo olwengeziwe lwezakhiwo ezibonakalayo.

I-High Reflectivity Yethusi Ikhuthaza Ukuthuthukiswa Kobuchwepheshe BeLaser Eluhlaza Neluhlaza

Ezintweni zensimbi, ukucutshungulwa kwe-laser kwensimbi nensimbi kuye kwahlolisiswa kahle. Kodwa-ke, ukucubungula izinto ezibonisa ukukhanya okuphezulu, ikakhulukazi ithusi ne-aluminium, kusacutshungulwa. I-Copper isetshenziswa kakhulu kumakhebula, izinto zikagesi zasendlini, izinto zikagesi ezithengwayo, izinto zikagesi, izakhi ze-elekthronikhi, namabhethri ngenxa yokuguquguquka kwayo okuhle kakhulu kokushisa nogesi. Naphezu kweminyaka eminingi yomzamo, ubuchwepheshe be-laser buye badonsa kanzima ukucubungula ithusi ngenxa yezakhiwo zayo.

Okokuqala, ithusi linokubonakala okuphezulu, ngezinga lokubonisa elingu-90% lelaser evamile engu-1064 nm infrared. Okwesibili, i-copper conductivity enhle kakhulu yokushisa ibangela ukushisa kuphele ngokushesha, okwenza kube nzima ukufeza umphumela wokucubungula oyifunayo. Okwesithathu, ama-lasers anamandla aphezulu ayadingeka ukuze kucutshungulwe, okungaholela ekulimaleni kwethusi. Ngisho noma ukushisela kuqediwe, amaphutha kanye nokushisela okungaphelele kuvamile.

Ngemuva kweminyaka yokuhlola, kutholakale ukuthi ama-laser anamaza amafushane amafushane, njengama-lasers aluhlaza naluhlaza, afaneleka kakhulu ukushisela ithusi. Lokhu kuqhubekisele phambili ukuthuthukiswa kobuchwepheshe be-laser eluhlaza nokuluhlaza.

Ukushintsha ukusuka kuma-laser e-infrared ukuya kuma-laser aluhlaza anobude beza beza obungu-532 nm kunciphisa kakhulu ukubonakala. I-532 nm wavelength laser ivumela ukuhlangana okuqhubekayo kwe-laser beam ezintweni zethusi, kuzinzisa inqubo yokushisela. Umthelela wokushisela ethusi ngelaser engu-532 nm uqhathaniswa nalowo welaser engu-1064 nm ensimbi.

E-China, amandla okuhweba ama-laser aluhlaza afinyelele kuma-watts angu-500, kanti emazweni ngamazwe afinyelele kuma-watts angu-3000. Umthelela we-welding ubaluleke kakhulu ezingxenyeni zebhethri ye-lithium. Eminyakeni yamuva nje, ukushiswa kwe-laser eluhlaza kwethusi, ikakhulukazi embonini entsha yamandla, sekuyinto evelele.

Njengamanje, inkampani yaseShayina ithuthukise ngempumelelo i-laser eluhlaza ehlanganiswe ngokuphelele ne-fiber enamandla okukhipha amandla angama-watts ayi-1000, eyandisa kakhulu izinhlelo zokusebenza ezingaba khona zokushisela ithusi. Umkhiqizo wamukelwa kahle emakethe.

Eminyakeni emithathu edlule, ubuchwepheshe obusha be-laser eluhlaza buye bathola ukunakwa kwemboni. Amalaser aluhlaza, anobude obungafinyelela ku-450 nm, awela phakathi kwama-laser e-ultraviolet namalaser aluhlaza. Ukumuncwa kwe-laser eluhlaza okwesibhakabhaka ku-copper kungcono kune-laser eluhlaza, kunciphisa ukukhanya kube ngaphansi kwama-35%.

I-laser welding eluhlaza okwesibhakabhaka ingasetshenziselwa kokubili i-thermal conduction welding kanye ne-deep penetration welding, ukufeza "i-spatter-free welding" kanye nokunciphisa i-weld porosity. Ngaphandle kokuthuthukisa ikhwalithi, i-laser eluhlaza okwesibhakabhaka yokushisela ithusi iphinde inikeze izinzuzo ezibalulekile zejubane, ishesha okungenani izikhathi ezinhlanu kune-infrared laser welding. Umphumela ozuzwe nge-laser ye-infrared engu-3000-watt ungafezeka ngelaser eluhlaza okwesibhakabhaka engu-500-watt, okonga kakhulu amandla nogesi.

Abakhiqizi beLaser Abathuthukisa I-Blue Lasers

Abakhiqizi abahamba phambili bamalaser aluhlaza bahlanganisa i-Laserline, Nuburu, United Winners, BWT, kanye ne-Han's Laser. Njengamanje, ama-laser aluhlaza amukela umzila wobuchwepheshe be-fiber-coupled semiconductor, obambezeleka kancane ekuminyana kwamandla. Ngakho-ke, ezinye izinkampani zenze i-dual-beam composite welding ukuze kuzuzwe imiphumela engcono yokushisela yethusi. Ukushisela i-dual-beam kuhilela kanyekanye ukusebenzisa imishayo ye-laser eluhlaza okwesibhakabhaka kanye nemishayo ye-laser ye-infrared yokushisela ithusi, ngokuma okuhlobene okulungiswe ngokucophelela kwamachashazi amabili emishayo ukuze kuxazululwe izinkinga zokubonakala okuphezulu ngenkathi kuqinisekiswa ukuminyana kwamandla okwanele.

Ukuqonda izakhiwo zezinto ezibalulekile kubalulekile uma usebenzisa noma uthuthukisa ubuchwepheshe be-laser. Kungakhathaliseki ukuthi kusetshenziswa ama-laser aluhlaza noma aluhlaza, womabili angathuthukisa ukumuncwa kwe-lases kwe-copper, nakuba ama-lases anamandla amakhulu aluhlaza okwesibhakabhaka nokuhlaza ebiza okwamanje. Kukholakala ukuthi njengoba amasu okucubungula ekhula kanye nezindleko zokusebenza zamalaser aluhlaza noma aluhlaza zehla ngokufanelekile, isidingo semakethe sizokhuphuka ngempela.

Ukupholisa Okuphumelelayo kwamaLaza Aluhlaza Nakuhlaza

Amalaser aluhlaza naluhlaza akhiqiza ukushisa okukhulu ngesikhathi sokusebenza, okudinga izixazululo eziqinile zokupholisa. U-TEYU Chiller, oholayo umkhiqizi we-chiller oneminyaka engu-22 yokuhlangenwe nakho, inikeza izixazululo zokupholisa ezifanelana nezinhlobonhlobo zezinhlelo zokusebenza zezimboni neze-laser. Uchungechunge lwethu lwe-CWFL ama-chillers amanzi aklanyelwe ngokukhethekile ukunikeza ukupholisa okunembayo nangempumelelo kwamasistimu e-fiber laser, okuhlanganisa lawo aqashwe ezinqubweni ze-laser eluhlaza okwesibhakabhaka nokuhlaza. Ngokuqonda izimfuno ezihlukile zokupholisa zemishini ye-laser, siletha ama-chiller anamandla futhi athembekile ukuze sithuthukise ukukhiqiza nokuvikela okokusebenza. 

U-TEYU Chiller usazibophezele ngokuhlala ephambili kubuchwepheshe bokupholisa nge-laser. Sihlala siqapha amathrendi embonini kanye nokuqanjwa okusha kwama-laser aluhlaza naluhlaza, siqhubekisela phambili intuthuko yezobuchwepheshe ukuze sikhuthaze ukukhiqiza okusha futhi sisheshise ukukhiqizwa kwama-chiller asungulayo ukuze ahlangabezane nezidingo zokupholisa eziguqukayo zemboni ye-laser.
