Ngesikhathi senqubo yokushisela, ukukhanya kwephuzu eliphakathi okunamandla aphezulu kwakha imbobo yokhiye yokushisela okujulile ukuze kutholakale ukungena okwanele kokushisela (okufana nokukhishwa kwe-laser yefayibha esixazululweni sokushisela esihlanganisiwe), futhi ukukhanya kwendandatho kunikeza ukufakwa okukhulu kokushisa, kwandisa imbobo yokhiye, kunciphisa umthelela womusi wensimbi kanye ne-plasma ensimbini ewuketshezi emaphethelweni embobo yokhiye, kunciphisa ukuchitheka kwensimbi okubangelwayo, futhi kwandise isikhathi somjikelezo wokushisa wokushisela, kusiza igesi echibini elincibilikisiwe ukuba iphume isikhathi eside, kuthuthukisa ukuzinza kwezinqubo zokushisela ezisheshayo (okufana nokukhishwa kwama-laser e-semiconductor ezixazululweni zokushisela ezihlanganisiwe).
Ekuhlolweni, sihlanganise amabhethri egobolondo aqinile futhi sathola ukuthi ukulingana kosayizi we-weld kwakukuhle kanye nekhono lenqubo ye-CPK lalilihle, njengoba kuboniswe kuMfanekiso 18.
Ukubukeka kokushisela kwesembozo sebhethri esiphezulu okunobukhulu bodonga obungu-0.8mm (isivinini sokushisela esingu-300mm/s)
Ngokuphathelene nehadiwe, ngokungafani nesixazululo sokushisela esihlanganisiwe, lesi sixazululo silula futhi asidingi ama-laser amabili noma ikhanda elikhethekile lokushisela elihlanganisiwe. Sidinga kuphela ikhanda elivamile elivamile lokushisela elinamandla aphezulu (njengoba i-fiber eyodwa kuphela ekhipha i-laser eyodwa ye-wavelength, isakhiwo selensi silula, akukho ukulungiswa okudingekayo, futhi ukulahleka kwamandla kuphansi), okwenza kube lula ukulungisa nokugcina, futhi ukuzinza kwemishini kuthuthuke kakhulu.
Ngaphezu kohlelo olulula lwesisombululo sehadiwe kanye nokuhlangabezana nezidingo zenqubo yokushisela esheshayo yesembozo sangaphezulu seseli yebhethri, lesi sixazululo sinezinye izinzuzo ekusetshenzisweni kwenqubo.
Esivivinyweni, sihlanganise isembozo sebhethri esiphezulu ngesivinini esiphezulu esingu-300mm/s, futhi sathola imiphumela emihle yokwenza umthungo wokushisela. Ngaphezu kwalokho, kumagobolondo anobukhulu obuhlukene bodonga obungu-0.4, 0.6, no-0.8mm, kuphela Ngokulungisa imodi yokuphuma kwe-laser, ukushisela okuhle kungenziwa. Kodwa-ke, ngezixazululo zokushisela ze-laser hybrid ze-dual-wave length, kuyadingeka ukushintsha ukucushwa kwe-optical kwekhanda lokushisela noma i-laser, okuzoletha izindleko ezinkulu zemishini kanye nezindleko zesikhathi sokulungisa amaphutha.
Ngakho-ke, indawo yendandatho ekhombayoukushisela nge-laserIsixazululo asikwazi nje kuphela ukufeza ukushisela kwesembozo esiphezulu ngesivinini esiphezulu ku-300mm/s futhi sithuthukise ukusebenza kahle kokukhiqizwa kwamabhethri kagesi. Ezinkampanini zokukhiqiza amabhethri ezidinga izinguquko zemodeli njalo, lesi sixazululo singathuthukisa kakhulu ikhwalithi yemishini nemikhiqizo, sinciphise ushintsho lwemodeli kanye nesikhathi sokulungisa amaphutha.
Ukubukeka kokushisela kwesembozo sebhethri esiphezulu ngobukhulu bodonga obungu-0.4mm (isivinini sokushisela esingu-300mm/s)
Ukubukeka kokushisela kwesembozo sebhethri esiphezulu okunobukhulu bodonga obungu-0.6mm (isivinini sokushisela esingu-300mm/s)
Ukungena kwe-Corona Laser Weld kokushisela amaseli amancane – Amakhono enqubo
Ngaphezu kwe-laser ye-Corona okukhulunywe ngayo ngenhla, ama-laser e-AMB nama-laser e-ARM anezici ezifanayo zokukhipha ukukhanya futhi angasetshenziswa ukuxazulula izinkinga ezifana nokuthuthukisa i-laser weld spatter, ukuthuthukisa ikhwalithi yobuso be-weld, kanye nokuthuthukisa ukuzinza kwe-welding okusheshayo.
4. Isifinyezo
Izixazululo ezahlukahlukene okukhulunywe ngazo ngenhla zonke zisetshenziswa ekukhiqizweni kwangempela yizinkampani zokukhiqiza amabhethri e-lithium zasekhaya nezakwamanye amazwe. Ngenxa yesikhathi sokukhiqiza esihlukile kanye nezizinda zobuchwepheshe ezahlukene, izixazululo zenqubo ezahlukene zisetshenziswa kabanzi embonini, kodwa izinkampani zinezidingo eziphakeme zokusebenza kahle kanye nekhwalithi. Kuthuthuka njalo, futhi ubuchwepheshe obusha obuningi buzosetshenziswa maduze yizinkampani eziphambili kwezobuchwepheshe.
Imboni entsha yamabhethri kagesi yaseShayina iqale sekwephuzile futhi ithuthuke ngokushesha iqhutshwa yizinqubomgomo zikazwelonke. Ubuchwepheshe obuhlobene buqhubekile nokuthuthuka ngemizamo ehlangene yochungechunge lonke lwemboni, futhi bunciphise ngokuphelele igebe nezinkampani zomhlaba wonke ezivelele. Njengomkhiqizi wemishini yamabhethri e-lithium yasekhaya, iMaven iphinde ihlole njalo izindawo zayo ezizuzisayo, isiza ekuthuthukisweni okuphindaphindiwe kwemishini yamaphakethe ebhethri, futhi ihlinzeka ngezixazululo ezingcono zokukhiqizwa okuzenzakalelayo kwamaphakethe amamojula ebhethri okugcina amandla amasha.
