Imibuzo Evamile Mayelana Nokwelashwa Kokushisa Nge-Laser

Ukwelashwa ngokushisa nge-laser sekuba ubuchwepheshe obubalulekile ekukhiqizeni kwesimanje, okunikeza ukunemba okuphezulu, izinzuzo zemvelo, kanye nokuzivumelanisa nezimo okuhle kakhulu nezinto ezintsha. Ngezansi, siphendula eminye yemibuzo evame kakhulu mayelana nale ndlela yokwelapha ubuso ethuthukisiwe.

Iyini isimiso esiyisisekelo sokwelashwa ngokushisa nge-laser?
Ukwelashwa ngokushisa nge-laser kusebenzisa umsebe we-laser onamandla aphezulu ukuze kushiswe futhi kupholiswe ubuso bento. Ngesikhathi esifushane kakhulu, i-laser iphakamisa izinga lokushisa lobuso ngaphezu kwendawo yokuqinisa. Njengoba ukushisa kunyamalala ngokushesha ngokusebenzisa ukushisa kwento, kwakheka isakhiwo se-martensitic esithambile kakhulu. Le nqubo ithuthukisa kakhulu ubulukhuni bobuso, ukumelana nokuguguleka, kanye namandla okukhathala.

Ukwelashwa ngokushisa nge-laser kubonisa kanjani ukunemba nokuguquguquka?
Enye yezinzuzo ezinkulu zobuchwepheshe be-laser yikhono layo lokulawula usayizi webala le-beam kuze kufike ezingeni le-micrometer. Lokhu kwenza kube lula ukuqinisa ama-geometri ayinkimbinkimbi njengemifantu yesikhunta, amazinyo egiya, nezinye izindawo eziyinkimbinkimbi. Embonini yezimoto, ukwelashwa ngokushisa nge-laser kusetshenziswa kabanzi ekuqiniseni izingxenye zenjini ngokunembile. Ekukhiqizeni isikhunta, kuthuthukisa kuphela izindawo eziguga kakhulu, kwandise impilo yesevisi ngaphandle kokuthinta lonke ithuluzi.

Kungani ukwelashwa ngokushisa nge-laser kubhekwa njengobungani nemvelo?
Ngokungafani nezindlela zokwelapha ukushisa zendabuko, ukwelashwa ngokushisa nge-laser akudingi manzi, uwoyela, noma ezinye izinto zokupholisa ngesikhathi sokusebenza. Lokhu kuqeda ukukhishwa kwamanzi amdaka futhi kunciphisa ukungcola, okuhambisana nezimiso zokukhiqiza oluhlaza. Inqubo ehlanzekile neqhubekayo yenza kube ukukhetha okuhle kwezimboni ezihlose ukunciphisa ukuthinteka kwazo kwemvelo.

Ukwelashwa ngokushisa nge-laser kuvumelana nezimo kangakanani ezintweni ezintsha?
Njengoba izinto ezilula zithola ukuthandwa, ikakhulukazi embonini entsha yezimoto zamandla, izinqubo zokwelapha ukushisa nge-laser ezizinikele ziye zaklanywa ze-alloys kanye nezinhlanganisela. Isibonelo, i-aluminium alloys iyazuza ezakhiweni zekristalu ezithuthukisiwe, okuholela ekuqineni okuphezulu kanye nokuqina. I-carbon fiber composites ingafinyelela izakhiwo ezingcono zobuso kanye nokusebenza okuqinile kokubopha, isekela isidingo esikhulayo sezinto ezilula nezihlala isikhathi eside ezinhlelweni zobunjiniyela ezithuthukisiwe.
