I-laser iwugqinsi wamandla okukhanya agxilile akhiqizwa ngobude obuthile begagasi. Emvelweni, ukukhanya kuba khona kuchungechunge lwamaza amaza, asukela kufushane kakhulu (ama-X-reyi nemisebe ye-gamma) kuya kude kakhulu (amaza omsakazo). Abantu bangabona kuphela amaza abonakalayo noma 'okukhanya okumhlophe' ukusuka cishe ku-430-690 nanometers (nm). I-laser beam iwukugxila okukhulisiwe kwamandla okukhanya kubude obuthile begagasi. Iwukukhanya okuhambisanayo, okuvumela ukugxila endaweni eqinile kanye ne-beam ewumngcingo ebangeni elide. Igama elithi laser liyisifinyezo esimelela ukukhulisa ukukhanya ngokukhipha okukhuthazwa kwemisebe.
I-Laser Welder Work Principle
I-laser beam ikhiqizwa ngaphakathi kwe-ruby crystal. I-ruby crystal yenziwe nge-aluminium oxide ene-chromium ehlakazeke kuyo yonke indawo. Okwakhiwa mayelana 1/2000 yekristalu, lokhu okungaphansi kwerubi yemvelo. Izibuko eziboshwe ngesiliva zifakwe ngaphakathi ezinhlangothini zombili zekristalu. Uhlangothi olulodwa lwesibuko lunembobo encane, ugongolo luphuma ngale mbobo.
Ishubhu elikhanyayo libekwe eduze kwekristalu ye-ruby, egcwele igesi ye-xenon inert. I-flash iklanywe ngokukhethekile njengokuthi yenziwe izinga lokukhanyisa mayelana nezinkulungwane zokukhanyisa ngesekhondi.
Amandla kagesi aguqulwa abe amandla okukhanya, lokhu kusetshenzwa nge-flash tube.
I-capacitor ihlinzekelwe ukugcina amandla kagesi futhi inikeze amandla kagesi aphezulu ku-flash tube ukuze yenziwe ngendlela efanele.
Amandla kagesi akhishwa ku-capacitor ne-xenon aguqula amandla aphezulu abe izinga lokukhanya kwe-flash elimhlophe elingu-1/1000 ngomzuzwana.
The chromium atoms of ruby crystals are excited and pumped into high energy. Due to heat generating some of this energy is lost. But some light energy reflected mirror to mirror and again chromium atoms are excited until loss of their extra energy simultaneously to form a narrow beam of coherent light. This comes out through the one end tiny hole of crystal's mirror.
Le nsimbi ewumngcingo igxiliswe ilensi yokugxilisa amehlo ukuze ikhiqize ugongolo oluncane lwelaser oluqinile endaweni yokusebenza.
Imishayo ye-laser iyashintsha lapho ihlangana nezinto ezibonakalayo
Ukumuncwa kwamandla e-laser kwento esebenzayo kuyehluka ngokuya ngenani lezici, njengobude beza, ukujiya kwempahla, ukwakheka kwekristalu, izithasiselo ezibonakalayo, ukwakheka kwamangqamuzana, nokuningi. Inqubo ithatha izinzuzo zalezi zakhiwo ezibonakalayo kanye ne-laser ukudala isibopho phakathi kwezinto ezi-2 zepulasitiki—edlulisa amandla e-laser kanye nenye ewamuncayo.
Uma i-laser beam ihlangana nanoma iyiphi into efana nepulasitiki, izodluliswa, ibonakale, noma imunce ngokusekelwe kubude begagasi nokwakheka kwezinto ehlangabezana nazo. Izinto eziningi zikhombisa izinga elithile layo yonke imiphumela emi-3, kodwa ngezilinganiso ezihlukene. Okubalulekile kungase kucace ngokusobala ukuze kukhanye ku-spectrum ebonakalayo futhi amunce kakhulu kulaser ye-infrared, noma kube opaque emehlweni ethu kodwa kubonakale ngale laser infrared.
I-Laser Welder Mechanics
Ukushisela nge-laser kuyinqubo ekhiqiza ukuhlangana kwezinto ngokushisa okutholakala ekusetshenzisweni kwe-beam yokukhanya ehambisanayo egxisha indawo okumele ihlanganiswe.
Kufezwa ngezigaba ezilandelayo:
1. Ukusebenzisana kwe-laser beam ngezinto zokusebenza.
2. Ukushisa nokukhuphuka kwezinga lokushisa.
3. Ukuncibilika kwe-vaporization nokuhlanganisa: Uma usebenzisa i-laser beam ukushisela, imisebe ye-electromagnetic icindezela phezu kwesisekelo sensimbi ngokuhlangana kwamandla kangangokuthi izinga lokushisa elingaphezulu liba umhwamuko oncibilikisiwe bese kwakheka ukuncibilika kwensimbi engezansi.
