Yiziphi izinzuzo laser Welding umshini?

Umshini wokushisela we-laseriye yacwaningwa kusukela kwazalwa ama-lasers ngawo-1960.Sekuyiminyaka ecishe ibe ngu-40 yentuthuko kusukela ekushiseleni izingxenye ezincane ezincane noma amadivaysi kuya ekusetshenzisweni kwamanje okukhulu kwe-laser welding yamandla aphezulu ekukhiqizeni kwezimboni.Yafundwa ngokucacile ekuqaleni kwekhulu lama-20.I-laser yokuqala yathuthukiswa ngo-1960. Eminyakeni emine kamuva, i-laser yokuqala ye-YAG solid-state kanye ne-CO2 gas laser zathuthukiswa.Kusukela lapho, imishini yokushisela i-laser ibilokhu isetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zezimboni.

1.Izinzuzo zeumshini wokushisela we-laseruma kuqhathaniswa nezindlela zendabuko zokushisela

① Ngaphambi kokufika kwe-laser welding, imboni yezimboni ibisebenzisa izindlela zendabuko zokushisela.Ngenxa yokushisa kwendawo engalingani kanye nokupholisa kwe-weldment, i-post-weld deformation ivame ukwenzeka, ngaleyo ndlela ihluleke ukuhlangabezana nezidingo zokushisela, futhi ngenxa yokuthi i-welding ayinembile ngokwanele, Kuzophinde kube nokuhlangana okungaphelele phakathi kwe-workpiece kanye nensimbi yokushisela noma ungqimba lwe-weld, kanye ne-weld iqukethe i-slag engeyona eyensimbi, edonsa igesi futhi ikhiqize ama-pores nezinye iziphambeko, okuvame ukubangela ukuthi izingxenye ezishiselwe ziqhekeke futhi zithinte ukusebenza kokuvala.

② I-laser welding inezinzuzo zokuminyana kwamandla aphezulu, ukuwohloka okuncane, indawo encane ethinteke ukushisa, isivinini esikhulu sokushisela, ukulawula okulula okuzenzakalelayo, futhi akukho ukucubungula kokulandelela.Eminyakeni yamuva nje, sekuyindlela ebalulekile yokucubungula nokukhiqiza izinto zensimbi.Isetshenziswa kabanzi ezimotweni, emkhathini, embonini yezokuvikela, ekwakhiweni kwemikhumbi, kwezobunjiniyela basolwandle, ezintweni zamandla enuzi nakweminye imikhakha, izinto ezihilelekile zimboza cishe zonke izinto zensimbi.

③ Nakuba kuqhathaniswa nezindlela zendabuko zokushisela, ukushisela nge-laser kusenezinkinga zemishini ebizayo, ukutshalwa kwezimali okukhulu kwesikhathi esisodwa kanye nezidingo eziphakeme zobuchwepheshe, okwenza ukusetshenziswa kwezimboni zokushisela i-laser ezweni lami kulinganiselwe, kodwa ukushiswa kwe-laser kunokukhiqiza okuphezulu nokusebenza kahle. kulula ukubona izici ezilawulwayo ezizenzakalelayo ziyenza ilungele imigqa yokukhiqiza ngobuningi kanye nokukhiqiza okuvumelana nezimo.

④ Okwamanje, ukushisela insimbi kunezidingo eziphakeme neziphakeme zamandla okushisela nokubukeka.Indlela yendabuko yokushisela izodala izinkinga ngokungenakugwenywa njengokuhlanekezela nokuguqulwa kwendawo yokusebenza ngenxa yokufakwayo okukhulu kokushisa.Ukuze kulungiswe inkinga ye-deformation, inani elikhulu lezinyathelo zokulandelela liyadingeka, okuholela ekwenyukeni kwezindleko.Indlela yokushisela i-laser ezenzakalelayo inokufaka okuncane kakhulu kokushisa nendawo encane kakhulu ethintekile ekushiseni, ethuthukisa kakhulu ikhwalithi yesiqeshana sokusebenza esishiselwe, inciphise izindleko zomsebenzi wokulandelela, futhi ithuthukise kakhulu ukusebenza kahle nokusimama kokushisela.

2.Amamodeli ahlukene, izinketho ezihlukahlukene

Kafushane, ubuchwepheshe bamanje be-laser welding buvuthwe kakhulu.Imishini yokushisela i-laserukusetshenziswa kwamandla okuphansi, ukunemba okuphezulu, nokungcoliswa kwemvelo okuncane.Izimboni zobuchwepheshe ziya ngokuya zikhetha imishini yokushisela i-laser ukuze kuqinisekiswe ikhwalithi yomkhiqizo nokuqinisekisa izinkampani namakhasimende.
