Ndi chitukuko chofulumira cha sayansi ndiukadaulo, makina odulira fiber laser agwiritsidwa ntchito kwambiri pamsika wamafakitale. Makina opangira ma fiber laser ali ndi kudula kwakukulu komanso kuthamanga mwachangu, komwe kumatha kukonza magwiridwe antchito ndi 60% ndikupulumutsa ndalama zambiri. Chifukwa chake, amakondedwa kwambiri ndi anthu. Chikondi, tsopano lolani opanga makina opangira makina a fiber amvetsetse kugwiritsa ntchito makina a fiber laser mumsika wamafakitale.
Pafupifupi zida zonse zachitsulo zimakhala ndi chiwonetsero chazithunzi zazitali kutentha kwapakati. Mwachitsanzo, kuchuluka kwa mayesedwe a 10,6um carbon dioxide laser ndi 0,5% mpaka 10% yokha, koma pomwe mtanda wolunjika wokhala ndi mphamvu yopitilira 10 ″ W / em2 umawala pazitsulo, zitha kukhala mu dongosolo la microseconds. Malo amkati amayamba kusungunuka. Mlingo woyamwa wazitsulo zambiri zosungunuka umakwera kwambiri, makamaka mpaka 60% -80%. Chifukwa chake, lasers ya carbon dioxide agwiritsidwa ntchito bwino munjira zambiri zachitsulo.
Kutalika kwakukulu kwa mbale yazitsulo ya kaboni yomwe imadulidwa ndi makina amakono odulira laser idapitilira 20mm. Njira yodulira mpweya wothandizidwa ndi mpweya imagwiritsidwa ntchito kudula mbale zachitsulo. Chidacho chimatha kuyang'aniridwa m'lifupi mokhutiritsa, ndikudula kwa mbale zachitsulo kumakhala kopapatiza ngati 0.1 mm. za. Laser kudula ndi ogwira processing njira mbale zosapanga dzimbiri. Imatha kuwongolera malo omwe akhudzidwa ndi kutentha pang'ono pang'ono, kuti asatengeke ndi dzimbiri. Zitsulo zambiri zamagetsi zamagetsi ndi zida zamagetsi zitha kugwiritsidwa ntchito kuti mupeze njira yabwino yodulira mwa kudula kwa laser.
Aluminiyamu ndi zotengera za aluminium sizingasungunuke ndikudulidwa ndi mpweya. Njira zosungunulira ndi kudula ziyenera kugwiritsidwa ntchito. Zotayidwa laser kudula amafuna mkulu mphamvu kachulukidwe kuti athane ndi reflectivity ake ndi 10.6um timaganiza laser. Mtengo wa YAG laser wokhala ndi kutalika kwa 1,06 um umatha kusintha kwambiri kudula ndi kuthamanga kwa zotayidwa za laser chifukwa chokwera kwambiri.
Mitundu ya titaniyamu ndi titaniyamu yomwe imagwiritsidwa ntchito kwambiri m'makampani opanga ndege imagwiritsa ntchito mpweya ngati gasi wothandizira. Mankhwalawa ndi owopsa ndipo liwiro lakucheka limathamanga, koma ndizosavuta kupanga gawo la oxide pamphepete komanso ngakhale kuyambitsa kutentha. Ndi bwino kugwiritsa ntchito mpweya wa inert ngati mpweya wothandizira, womwe ungatsimikizire kuti kudula ndikofunika.
