Pakali pano, m'manja laser kuwotcherera makina akhala ankagwiritsa ntchito m'munda wa kuwotcherera zitsulo. M'munda wowotcherera wachikhalidwe, 90% ya kuwotcherera zitsulo yasinthidwa ndi kuwotcherera kwa laser chifukwa cha liwiro la kuwotcherera la laser kukhala loposa kasanu kuposa njira zachikhalidwe zowotcherera, ndipo mphamvu yowotcherera ili kutali kwambiri ndi kuwotcherera kwachikhalidwe kwa argon ndi kuwotcherera kotetezedwa. Kuwotcherera kwa laser pakuwotcherera zitsulo zopanda chitsulo monga aloyi ya aluminiyamu kuli ndi mwayi wanjira yowotcherera yachikhalidwe. Kumene, pankhani kuwotcherera zitsulo zipangizo, m'manja laser kuwotcherera makina amakhalanso ndi kusamala.
Chinthu choyamba ndikuwona ngati chotsekera chotsekeracho chili choyera, chifukwa magalasi osadetsedwa amatha kuwonongeka pakagwiritsidwa ntchito, zomwe pamapeto pake zimabweretsa kulephera kosatheka. Pamene laser yakonzeka kupita pambuyo pake kwathunthu. Ndi chitukuko cha luso luso kuwotcherera laser, m'manja laser kuwotcherera luso kukhwima ndipo akhala ntchito zosiyanasiyana minda mafakitale. Komabe, popanga ndikugwiritsa ntchito tsiku ndi tsiku, chifukwa cha zifukwa zosiyanasiyana, padzakhalabe nkhani zina. Chifukwa chake, kuwongolera ndi kuthetsa nkhani zomwe zimakhudza magwiridwe antchito ndizofunikira kwambiri. Nthawi zambiri, timazindikira chomwe chimayambitsa vutoli pogwiritsa ntchito zochitika ndi kuwongolera mosiyanasiyana.
Nthawi zambiri, pali zifukwa ziwiri zomwe zimapangitsa kuti munthu asagwire bwino ntchito:
1. Ngati pali vuto ndi kukonza zinthuzo, zinthu zolakwika ziyenera kusinthidwa kuti zikwaniritse zotsatira zomwe mukufuna.
2. Kukonzekera kwa magawo aukadaulo kumafuna kuyesa kosalekeza kwa zigawo zomwezo molingana ndi zomwe zidapangidwa ndi welded ndi zokambirana zochokera ku zotsatira za mayeso.
Kuphatikiza apo, kuwotcherera kwa laser kuli ndi zabwino zambiri zomwe kuwotcherera kwachikhalidwe sikungafanane:
1. Chitetezo. Mphuno ya tochi idzangoyamba kugwira ntchito ikakumana ndi zitsulo, kuchepetsa chiopsezo cha misoperation, ndi kukhudza kusinthana kwa nyali yowotcherera nthawi zambiri kumakhala ndi ntchito yozindikira kutentha, yomwe idzasiya kugwira ntchito pamene yatenthedwa kwambiri.
2. Kuwotcherera kulikonse kungatheke. Kuwotcherera kwa laser sikuti kumangogwira ntchito bwino pama welds wamba, komanso kumasinthasintha kwambiri komanso kuwotcherera bwino pama welds ovuta, zida zazikulu zogwirira ntchito, komanso zowotcherera zosawoneka bwino.
3. Kuwotcherera kwa laser kungathandize kukhalabe ndi malo ogwirira ntchito pafakitale. Kuwotcherera kwa laser kumakhala ndi spatter yochepa komanso mphamvu yowotcherera yokhazikika, yomwe ingachepetse kwambiri kuipitsa mkati mwa fakitale ndikuonetsetsa kuti malo ogwira ntchito amakhala oyera.
Komabe, kuwotcherera laser kulinso ndi zofunika zina pakugwiritsa ntchito kwenikweni, monga kutengera mawonekedwe ochezeka a zida zowotcherera za laser, ndikuwongolera ndikuwongolera njira yopanga zitsulo. Kuwotcherera kwa laser kulinso ndi zofunika kwambiri pakuwongolera kulondola komanso mtundu wamakonzedwe. Ngati mukufuna kupereka kusewera kwathunthu kwaubwino wa kuwotcherera kwa laser, kuchepetsa ndalama ndikuwongolera magwiridwe antchito, ndikofunikira kukhathamiritsa kupanga zitsulo kapena zitsulo zina popanga zenizeni. Monga kupanga mankhwala, laser kudula, kupondaponda, kupinda, kuwotcherera laser, etc., kukulitsa njira kuwotcherera kwa laser kuwotcherera, akhoza kuchepetsa mtengo kupanga fakitale ndi pafupifupi 30%, ndi kuwotcherera laser wakhala kusankha mabizinezi zambiri.
Zovuta za kuwotcherera kwa aluminium alloy laser:
1. Aluminiyamu alloy ali ndi makhalidwe opepuka, sanali maginito, otsika kutentha kukana, dzimbiri kukana, zosavuta kupanga, etc., choncho chimagwiritsidwa ntchito pa ntchito kuwotcherera. Kugwiritsa ntchito aloyi ya aluminiyamu m'malo mwa kuwotcherera mbale kungathe kuchepetsa kulemera kwa nyumbayo ndi 50%.
2. Aluminiyamu aloyi kuwotcherera n'zosavuta kubala pores.
3. Kukula kwa mzere wowonjezera wa aluminiyamu alloy weld ndi yayikulu, yomwe imatha kuyambitsa kupunduka pakuwotcherera.
4. Kuwotcherera kwa matenthedwe kumakonda kuchitika panthawi yowotcherera aluminum alloy, zomwe zimapangitsa ming'alu yamafuta.
5. Zopinga zazikulu zomwe zimalepheretsa kutchuka ndi kugwiritsa ntchito aloyi ya aluminiyamu ndi kufewetsa kwakukulu kwa zolumikizira zowotcherera komanso kutsika kwamphamvu kwamphamvu.
6. Pamwamba pa aluminiyumu alloy ndi yosavuta kupanga filimu ya refractory oxide (malo osungunuka a A12O3 ndi 2060 °C), omwe amafunikira njira yowotcherera yamphamvu kwambiri.
7. Aluminiyamu alloy ali ndi matenthedwe matenthedwe apamwamba (pafupifupi 4 nthawi ya chitsulo), ndipo pansi pa liwiro lomwelo kuwotcherera, kulowetsamo kutentha kumakhala 2 mpaka 4 kuposa chitsulo chowotcherera. Chifukwa chake, kuwotcherera kwa aluminium alloy kumafuna kachulukidwe kakang'ono kamphamvu, kuyika kwa kutentha kwapang'onopang'ono komanso kuthamanga kwambiri.
