Ubuchwepheshe be-Laser Welding

Njengobuchwepheshe bokuxhumana obusebenzayo,laser weldingiye yasetshenziswa kabanzi emikhakheni eminingi eminyakeni yamuva, ikakhulukazi kuukukhiqiza izimoto, i-aerospace, izisetshenziswa zezokwelapha nezimboni zokukhiqiza izinsimbi ezinembayo. Intuthuko yakamuva yezobuchwepheshe igxile kakhulu ekuthuthukiseni ikhwalithi yokushisela, ukuthuthukisa ukuguquguquka kwenqubo nokwandisa ububanzi bokufaka isicelo.

1. Ukusetshenziswa kwe-laser eluhlaza okwesibhakabhaka: Ngenxa yenkinga yokushisela yezinto ezibonisa ukukhanya okuphezulu njengethusi ne-aluminium, ama-laser aluhlaza angafinyelela ukushisela okuhlanzekile ngamandla aphansi ngenxa yezinga lawo eliphakeme lokumuncwa kulezi zinto kunama-lasers e-infrared.

Ama-laser semiconductor aluhlaza ayaqhubeka nokukhuthaza izinguquko ezindleleni zokucubungula zezinto ezibonisa ukukhanya okuphezulu njengethusi ne-aluminium. Uma kuqhathaniswa nokukhanya kwe-infrared, izinga eliphezulu lokumunca lokukhanya okuluhlaza okwesibhakabhaka ezinsimbi ezibonisa ukukhanya okuphezulu kuletha izinzuzo ezinkulu ezinhlelweni ezivamile zezimboni (ezifana nokusika nokushisela). Uma kuqhathaniswa nokukhanya kwe-infrared, ukukhanya okuluhlaza okwesibhakabhaka kunobude obufushane begagasi kanye nokushona okuphansi kokushona. Lesi sici sokukhanya okuluhlaza okwesibhakabhaka futhi senza kube lula ukusetshenziswa emikhakheni emisha njengokucubungula ifilimu elincanyana. Ngaphezu kokucutshungulwa kwezinto ezibonakalayo, ukusetshenziswa kokukhanya okuluhlaza kwezokwelapha, ukukhanyisa, ukupompa, izicelo zabathengi neminye imikhakha nakho kuye kwaheha ukunaka okukhulu.

2. Ubuchwepheshe be-Swing welding: I-laser-specific swing welding head inyakazisa ugongolo, olungagcini nje ukwandisa ububanzi bokucubungula, kodwa futhi kwandisa ukubekezelelana kububanzi be-weld, ngaleyo ndlela kuthuthukise izinga lokushisela.

Izinzuzo ze-swing welding

Ubukhulu bendawo yokushwiba busiza ukuvala izikhala ezinkulu

Ukubekezelelana okudingekayo kuphansi, kunciphisa izinto ezisetshenziswayo zokushisela nokunciphisa izindleko zokucubungula

Isikhathi sokushisela sincishiswa sibe ingxenye eyodwa kweshumi, okwandisa ukuphuma kwe-welding

Yehlisa noma ususe ngisho nesikhathi sokuqondisa ama-welds, uthuthukise ukukhiqiza

Yehlisa ukuguqulwa kwengxenye futhi uthuthukise ikhwalithi yesisetshenziswa

Ukushiselwa kwezinto ezingafani (insimbi nensimbi, insimbi engagqwali ne-chromium-nickel-inconel, njll.)

I-spatter ephansi, ingasetshenziselwa izinto zokushisela ezijwayele ukuqhekeka

Nciphisa kakhulu ukucubungula kwangemuva (ukuhlanza, ukugaya...)

Inkululeko enkulu ngokwengxenye yokuklama

I-3.I-Double-focus laser welding: Ucwaningo luye lwabonisa ukuthi i-double-focus laser welding izinzile futhi iyalawuleka kunezindlela zendabuko zokugxila okukodwa, ukunciphisa ukuguquguquka kwe-keyhole nokuthuthukisa ukuzinza kwenqubo yokushisela.

I-4.Ubuchwepheshe bokuqapha inqubo ye-Welding: Ngokusebenzisa ubuchwepheshe obuhambisanayo be-interferom etric imaging, uhlelo olusha lokuqapha i-welding welding luthuthukisiwe olungavumelanisa nezinguquko ze-geometry ye-keyhole ezinkambisweni ezahlukene, ukuhlinzeka ngesilinganiso esinembile sokujula kanye nezixazululo zokuqapha ezenziwe ngokwezifiso zenqubo yokushisela.

5. Ukuhlukahluka kwamakhanda we-laser welding: Ngokuthuthuka kobuchwepheshe, amakhanda we-laser welding nawo angeniswe ngezinhlobo ezahlukahlukene ngokuya ngemisebenzi nezidingo, okuhlanganisa amakhanda okushisela anamandla amakhulu, amakhanda okuskena we-laser galvanometer, amakhanda okushisela e-welding, njll., ukuhlangabezana nezidingo ezahlukene zokushisela.
