Mafuta osawoneka komanso osawoneka ', omwe sangathe kunyalanyazidwa mu laser yotchedwa laser, amatanthauza mpweya wotchinga. Kusankhidwa kwake kumakhudza mtunduwo mwachindunji, ndi mtengo wowuma. Lero, Cangoo Tech alankhula nanu za chidziwitso chotsimikizika cha mpweya wokhudzana ndi mpweya.
1. Udindo wa malo oteteza
Mu laser yowuzidwa, mpweya wotchinga udzakhudza zokongoletsera, weld wed, ulalo wotayirira, wolondera ndi kulowa m'lifupi. Nthawi zambiri, kuwomba mpweya wotetezedwa udzakhala ndi zotsatira zabwino pa weld, koma kungabweretsenso zovuta.
Zotsatira Zabwino
1) Kusungunuka koyenera kwa mpweya wotchinga kumateteza bwino dziwe la ma weld kuti muchepetse kapena kupewa makiya;
2) Kuwomba koyenera kwa mpweya wotchinga kumatha kuchepetsa nthawi yopumira yomwe imapangidwa potentha;
3) Kusungunuka koyenera kwa mpweya woteteza kungalimbikitse kufalikira kwa dziwe lokazinga pomwe chimalimbika, kupanga yunifolomu yowonera komanso yokongola;
4) Kuwomba kwa gasi yoteteza kumatha kuchepetsa kuchita bwino kwambiri kwa zitsulo za vapor ntrase kapena plasma mtambo wa laser, ndikuwonjezera kuchuluka kwa laser;
5) Kuwomba kwa mpweya wotchinga kumatha kuchepetsa nkhawa kwambiri.
Malingana ngati mtundu wamagesi, kuchuluka kwa mpweya, komanso njira yolumikizira mipweya imasankhidwa molondola, zotsatira zabwino zitha kupezeka. Komabe, kugwiritsa ntchito pogwiritsa ntchito mpweya wotchinga kumathanso kukhala ndi zovuta zobwera.
Zotsatira zoyipa
1) Kusungunuka kosayenera kwa mpweya wotchinga kumatha kuchititsa seams yosauka;
2) Kusankha mpweya wolakwika kumatha kuyambitsa ming'alu mu udzu, ndipo kungayambitsenso kuchepa kwa makina a weld;
3) Kusankha mtengo wolakwika wa mpweya ungayambitse mafuta ochulukirapo ochulukirapo (ngakhale kuti mtengo wowuma ndi wokulirapo kapena wocheperako), ndipo angapangitsenso chitsulo cham'madzi kuti chisasokonezeke kapena kuwonongeka;
4) Kusankha njira yolakwika yamagesi kudzapangitsa kuti katundu asafikire kapena ngakhale osateteza kapena kusokoneza mapangidwe a Weldwa;
5) Kusunga mpweya woteteza kumapangitsa kuti kulowetsedwa kwa ulesi, makamaka potcheretsa mbale zowonda, kumachepetsa ulalo wa Welld.
2. Mitundu ya mpweya woteteza
Nthawi zambiri zogwiritsidwa ntchito zotchinga za laser zimaphatikizapo nayitrogeni, argon, ndi helium, ndi mapangidwe awo ndi osiyana, kotero zotsatira za zokongoletsera ndizosiyananso.
1) nayitrogeni
Mphamvu yosungunuka ya nayitrogeni imakhala yopaka, yapamwamba kuposa ya Argon, yotsika kuposa helium, ndipo imatha kuchepetsa mapangidwe a plasma, potero akuwonjezera kuchuluka kwa laser. Nitrogen amatha kuchitira ndi aluminiyamu iloy ndi chitsulo cha kaboni pamtunda wina kuti apange nitrides a aluminiyamu a aluminiyamu ndi ma carbon zitsulo zotetezedwa.
Nayitrogeni wopangidwa ndi mankhwala pakati pa nayitrogeni ndi chitsulo chosapanga dzimbiri chimatha kuwonjezera mphamvu ya zolumikizana, zomwe zimathandizira kukonza makina a zokongoletsera, kotero nayitrogeni amatha kugwiritsidwa ntchito ngati mpweya wotchinga ukamatsegula chitseko chosapanga dzimbiri.
2) Argon
Mphamvu ya mankhwala a Argon ndi yotsika kwambiri, ndipo digiri ya ionition ndi yokwera pansi pa laser, yomwe siyingakhale yothetsa kuwongolera mapangidwe a plasma ndipo idzakhala ndi vuto linalake la laser. Komabe, argon ali ndi ntchito zochepa ndipo ndizovuta kuphatikiza ndi zitsulo wamba. Mankhwala amachitika, ndipo mtengo wa Argon sunali wokwera. Kuphatikiza apo, kachulukidwe ka Argon ndiwokwera, womwe umatha kumira pamwamba pa dziwe lowotchera, lomwe limatha kuteteza dziwe lowonera, kotero itha kugwiritsidwa ntchito ngati mankhwala wamba.
3) helium
Mphamvu ya ionization ya helium ndi yapamwamba kwambiri, ndipo digiri ya ionition ndi yotsika kwambiri pansi pa laser, yomwe imatha kuwongolera mapangidwe a plasma. Laser amatha kuchita zitsulo bwino, ndipo ntchito ya helium ndi yotsika kwambiri, ndipo kwenikweni sizimachita zitsulo. , ndi msoko wabwino kwambiri wotchinga mpweya, koma mtengo wa helium ndi wokwera kwambiri, ndipo zinthu zopangidwa ndi zambiri sizimagwiritsa ntchito gasi ili. Helium imagwiritsidwa ntchito pofufuza zasayansi kapena zinthu zomwe zimakhala ndi mtengo wowonjezereka kwambiri.
Ngati muli ndi mafunso kapena zosowa za Chitoliro cha laser chowuma pa Makina Chimake chubati mphesa , chonde khalani omasuka kulumikizana nafe kuyankhana.
