I-laser welding inqubo
Yaziswa kakhulu futhi isetshenziswa kabanzi embonini yezimoto, lapho amaphaneli ezimoto engenye yezigaba ezinhlanu ezinkulu ze-laser welding.
Isetshenziswa ezimotweni, inganciphisa isisindo somzimba wemoto, ithuthukise ukunemba komhlangano womzimba wemoto, ikhulise ukuqina komzimba wemoto, futhi yehlise izindleko zokugxiviza nezokuhlanganisa ohlelweni lokukhiqiza lomzimba wemoto.
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nezokusika - Imboni Yokushisela Nokusika YaseChina Nabahlinzeki (xinfatools.com)
Inqubo yokushisela isitaki se-laser yezingxenye zephaneli yezimoto
Lapho i-laser beam enamandla amakhulu afinyelela kububanzi obuthile (106~107 W/cm2) ikhipha imisebe ebusweni, okokusebenza kudonsa amandla okukhanya futhi kuguqule kube amandla okushisa. Impahla iyashisisa, iyancibilika, bese ihwamuka, ikhiqize umhwamuko wensimbi omningi, ophuma phezulu. Ngaphansi kwamandla okusabela akhiqizwe i-laser, uketshezi lwensimbi oluncibilikisiwe lududulwa ukuze lwakhe imigodi. Njengoba i-laser iqhubeka nokushiswa, imigodi ingena ijule. Lapho i-laser iyeka ukukhipha imisebe, uketshezi oluncibilikisiwe oluzungeze imigodi lugeleza lubuye luphinde luphole luqine. Hlanganisa ama-workpieces amabili ndawonye.
Izinto ezithinta i-laser welding
1. Amandla e-laser
Kukhona i-laser energy density threshold ku-laser welding. Ngaphansi kwaleli xabiso, ukuncibilika kwendawo yokusebenza kuphela, futhi ukujula kokungena akujulile kakhulu, okungukuthi, i-welding yenziwa ngohlobo oluzinzile lokuqhuba ukushisa; uma leli nani selifinyelelwe noma leqiwe, i-plasma izokhiqizwa, okuwuphawu Ngokuqhubeka kwe-welding yokungena okujulile okuzinzile, ukujula kokungena kuzokwanda kakhulu. Uma amandla e-laser engaphansi kwalo mngcele futhi ukuminyana kwamandla e-laser kuncane, ukungena okwanele kuzokwenzeka futhi ngisho nenqubo yokushisela ngeke izinze.
2. Isivinini sokushisela
Ijubane lokushisela linethonya elikhulu ekujuleni kokungena. Ukwandisa isivinini kuzokwenza ukungena kungabi mnyama, kodwa uma ijubane liphansi kakhulu, kuzodala ukuncibilika ngokweqile kwezinto kanye nokushisela kwe-workpiece. Ngakho-ke, kukhona uhla lwejubane lokushisela olufanele lwento ethile enamandla athile e-laser nogqinsi oluthile, futhi ukungena okuphezulu kungatholwa ngenani elihambisanayo lejubane.
3. Defocus inani
Ukugcina ukuminyana kwamandla okwanele, indawo yokugxila ibalulekile. Endizeni ngayinye kude nalapho kugxilwe khona i-laser, ukusatshalaliswa kokuminyana kwamandla kuyafana. Kunezindlela ezimbili ze-defocus: i-defocus enhle kanye ne-negative defocus. Uma indiza egxilile ingaphezu kocezu lokusebenza, i-positive defocus, futhi uma ingaphezulu kwendawo yokusebenza, i-negative defocus. Izinguquko ku-defocus zithinta ngqo ububanzi nokujula kwe-weld.
4. Igesi evikelayo
Ngesikhathi senqubo yokushisela i-laser, amagesi angenayo avame ukusetshenziselwa ukuvikela ichibi elincibilikisiwe, kepha ezisetshenziswa eziningi, amagesi anjenge-argon, i-nitrogen, ne-helium avame ukusetshenziselwa ukuvikela ukuvikela ucwecwe lokusebenza ku-oxidation ngesikhathi senqubo yokushisela nokuphephetha. i-plasma.
