Kukula kwa mainchesi a laser pachimake kudzakhudza kutayika kwa kufalikira komanso kugawa kwamphamvu kwa kuwala. Kusankha koyenera kwa mainchesi apakati ndikofunikira kwambiri. Kuchulukirachulukira kwapakati kumabweretsa kusokonekera komanso kubalalitsidwa pakupatsirana kwa laser, kukhudza mtundu wa mtengo komanso kulondola kwambiri. Kuchepa kwapakati pakatikati kumapangitsa Kulumikizana kwa mphamvu ya kuwala kwamtundu umodzi kumakhala koipitsitsa, komwe sikungathandize kufalitsamkulu-mphamvu laser.
1. Ubwino ndi ntchito yaing'ono pachimake awiri lasers (<100um)
Zinthu zonyezimira kwambiri: aluminium, mkuwa, chitsulo chosapanga dzimbiri, faifi tambala, molybdenum, etc.;
(1)Zida zowunikira kwambiri zimafunikira kusankha laser yaying'ono yapakati. The mkulu mphamvu kachulukidwe laser mtengo ntchito mwamsanga kutenthetsa zinthu kuti liquefied kapena vaporized boma, amene bwino laser mayamwidwe mlingo wa zinthu ndi kukwaniritsa kothandiza ndiponso mofulumira processing. Kusankha laser yokhala ndi mainchesi akulu kumatha kubweretsa kuwunikira kwambiri. , zomwe zimatsogolera ku kuwotcherera pafupifupi komanso ngakhale kuwotcha kwa laser;
Zipangizo zotha kuthyoka: nickel, nickel-plated copper, aluminium, chitsulo chosapanga dzimbiri, titaniyamu aloyi, etc.
Izi nthawi zambiri zimafunikira kuwongolera kokhazikika kwa malo omwe amakhudzidwa ndi kutentha ndi dziwe laling'ono losungunuka, kotero ndikofunikira kusankha laser yaying'ono yapakati;
(3)Kulowa kuwotcherera kwambiri kumafuna kukonza kothamanga kwambiri kwa laser, ndipo ndikofunikira kusankha laser yokhala ndi kachulukidwe kakang'ono kamphamvu kuonetsetsa kuti mphamvu ya mzere ndi yokwanira kusungunula zinthuzo pa liwiro lalikulu, makamaka pakuwotcherera lap, kuwotcherera kulowa, etc., zimafuna kuya kwapamwamba kolowera. Ndi bwino kusankha yaing'ono pachimake awiri laser oyenera.
2. Ubwino ndi kugwiritsa ntchito kwa lasers yayikulu m'mimba mwake (> 100um)
Large pachimake m'mimba mwake ndi malo lalikulu, lalikulu kutentha kuphimba dera, malo ochitirapo zambiri, ndipo kokha yaying'ono kusungunuka kwa zinthu pamwamba zimatheka, amene ali oyenera kwambiri ntchito laser cladding, laser remelting, laser annealing, laser kuumitsa, etc. minda iyi, lalikulu kuwala malo zikutanthauza mkulu kupanga dzuwa ndi zofooka m'munsi (kuwotcherera matenthedwe conductive pafupifupi alibe chilema).
Malinga ndikuwotcherera, malo aakulu amagwiritsidwa ntchito makamakakuwotcherera kompositi, yomwe imagwiritsidwa ntchito pophatikiza ndi laser yaying'ono yapakati: malo akuluwo amapangitsa kuti zinthuzo zisungunuke pang'ono, kusinthika kuchokera ku zolimba kupita kumadzimadzi, zomwe zimasintha kwambiri mayamwidwe azinthuzo ku laser, kenako amagwiritsa ntchito pachimake pang'ono. ndondomekoyi, chifukwa preheating kwa malo lalikulu, pambuyo processing, ndi lalikulu kutentha gradient woperekedwa kwa dziwe losungunuka, zinthu si sachedwa ming'alu zilema chifukwa cha kutentha mofulumira ndi kuzirala mofulumira. Itha kupangitsa mawonekedwe a weld kukhala osalala ndikukwaniritsa spatter yotsika kuposa njira imodzi ya laser.
