Chifukwa chachikulu chomwe kuwotcherera kwa makina owotcherera a laser kumakhala kwakuda kwambiri nthawi zambiri kumakhala chifukwa chamayendedwe olakwika a mpweya kapena kusakwanira kwa mpweya wotchinga, zomwe zimapangitsa kuti zinthuzo zikhale ndi oxidize pokhudzana ndi mpweya panthawi yowotcherera ndikupanga okusayidi wakuda. pa
Kuti athetse vuto la welds wakuda mu makina owotcherera laser, njira zotsatirazi zikhoza kuchitidwa:
1. Sinthani kayendedwe ka gasi wotchinga: Onetsetsani kuti kutuluka kwa mpweya wotchinga ndikokwanira kuphimba malo onse owotcherera ndikuletsa mpweya wa mpweya kulowa mu weld. Mayendedwe a mpweya wa mpweya wotchinga ayenera kukhala wotsutsana ndi momwe akugwirira ntchito kuti atsimikizire kudzipatula kwa mpweya.
2. Konzani bwino ntchito ya zinthu: Musanawotchere, gwiritsani ntchito zosungunulira monga mowa ndi acetone kuti muyeretse bwino zinthuzo kuti muchotse filimu yamafuta ndi oxide. Pazinthu zomwe zimakhala ndi okosijeni mosavuta, pickling kapena kutsuka kwa alkali zitha kugwiritsidwa ntchito pokonzekera kuti muchepetse ma oxides apamtunda.
3 . Sinthani magawo a laser: Khazikitsani mphamvu ya laser moyenera kuti mupewe kutentha kwambiri. Moyenera onjezerani liwiro la kuwotcherera, kuchepetsa kulowetsa kwa kutentha, ndi kuteteza zinthuzo kuti zisatenthe. Gwiritsani ntchito kuwotcherera kwa laser pulsed kuti mukwaniritse zowongolera zowongolera kutentha posintha kuchuluka kwa kugunda ndi ma frequency.
4. Limbikitsani malo owotchera: Yeretsani malo ogwirira ntchito pafupipafupi kuti fumbi ndi chinyezi zisalowe m'malo owotcherera. Zinthu zikalola, gwiritsani ntchito zida zowotcherera zotsekedwa kuti mulekanitse zonyansa zakunja.
Njira zomwe zili pamwambazi zimatha kuchepetsa vuto lakuda kwa zitsulo zowotcherera ndikuwongolera khalidwe la kuwotcherera ndi luso.
