Thola izimo zokusebenza zokushisela okunembile ezimotweni, i-aerospace, nasekukhiqizeni izinto zikagesi. Izibonelo zangempela ezibonisa izinzuzo zezindleko nekhwalithi zobuchwepheshe be-laser welding.
Ukushisela nge-laser sekushintshile kusuka kubuchwepheshe obukhethekile kuya enqubweni ebalulekile yokukhiqiza emikhakheni eminingi. Ukunemba, isivinini, nokuncipha kokushisa okuncane kuyenza ifanelekele ukuhlanganiswa kwezinto ezibalulekile lapho ikhwalithi ingeke yekethiswa.
Ukuhlanganiswa Kwemoto Nokuhlanganiswa Kwebhethri
Abakhiqizi bezimoto basebenzisa i-fiber laser welding ekuhlanganiseni uhlaka lomnyango, amaphaneli ophahla, nezindawo ze-aluminium zebhethri. I-laser eyodwa engu-2kW ishiselela izinhlaka zensimbi ngokushesha okungu-40% kune-MIG welding ngenkathi inciphisa isikhathi sokugaya ngemva kokushisela ngama-60%. Izindlu zamabhethri zizuzisa endaweni encane yokushisa, ivimbela ukulimala kwezingxenye zangaphakathi. Umkhiqizo ojwayelekile: izimoto eziyi-200-300 ngoshift ngasinye esiteshini esisodwa.
Izingxenye Ezibalulekile Ze-Aerospace
Izindlu ze-titanium alloy turbine, ama-blades e-nickel superalloy, nezingxenye ze-aluminium fuselage zidinga ama-weld angena-porosity. I-laser welding ifinyelela lokhu ngokulawula ukushisa okunembile nokuvikela nge-vacuum noma i-inert-gas. Amajoyinti ezinga le-aerospace ahlolwa ngokugcwele nge-X-ray noma ukuhlolwa kwe-ultrasonic. Izikhathi zokulethwa zandiswa amasonto angu-6-8 kulezi zinhlelo ngenxa yezidingo zokulandeleka nezitifiketi.
Ukukhiqizwa Kwezinto Zikagesi Nezinzwa
Ukuhlanganiswa okuncane kwezindlu zezinzwa, ama-hermetic seals, nama-hybrid circuits kusebenzisa ama-fiber laser angu-50-100W noma amasistimu e-green wavelength. I-beam egxilile (kuze kufike ku-50 microns) ihlanganisa izintambo ezincane ngaphandle kokulimaza izingxenye ezizungezile. Abakhiqizi bemishini yezokwelapha bathembele kulokhu ekuhlanganiseni ama-implant. Amazinga okukhiqiza: ama-micro-welds angu-3000-5000 ngoshift lwamahora angu-8 kuye ngobunkimbinkimbi bengxenye.
Izindleko Nezilinganiso Zekhwalithi
Iwindi elijwayelekile le-ROI: izinyanga eziyi-18-24 emigqeni ehlanganisiwe ye-laser welding. Amazinga okulahla ehla kusuka ku-2-3% (ukushisela okujwayelekile) kuya ku-0.3-0.5% (i-laser). Ukonga kwezinto ezisetshenziswayo kusuka ekwehliseni ukusebenza kabusha kunciphisa ukuncipha kwemali yemishini. Izinto ezisetshenziswayo (igesi, amathiphu) ziphansi kunezinhlelo ze-MIG; abasebenzi bayi-15-20% yezindleko zomnyango wokushisela.
