Kodi mungatani kuti muthane ndi kusintha kwa laser welding?

Chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha makhalidwe ake apadera monga kukana dzimbiri komanso kupangika mosavuta. Ndi kupita patsogolo kwa ukadaulo, kuwotcherera kwa laser kwakhala njira yatsopano yowotcherera, yomwe ili ndi zabwino zambiri poyerekeza ndi njira zachikhalidwe zowotcherera. Komabe, chimodzi mwazovuta zakuwotcherera ndi laserndi kusintha kwa chitsulo chosapanga dzimbiri. M'nkhaniyi, tikambirana momwe tingapewere kusintha kwa laser welding ya chitsulo chosapanga dzimbiri ndikufufuza zinthu zokhudzana ndi izi.

Choyamba, ndikofunikira kumvetsetsa chifukwa chake kuwotcherera kwa laser kumayambitsa kusintha kwa chitsulo chosapanga dzimbiri. Kuwotcherera kwa laser kumaphatikizapo kugwiritsa ntchito kuwala kwa laser komwe kumakhala ndi mphamvu zambiri kuti kusungunuke ndikugwirizanitsa pamwamba pa zitsulo ziwiri pamodzi. Panthawiyi, kutentha ndi kuzizira mwachangu kumayambitsa kusintha kwa kutentha, komwe kumayambitsa kusintha kwa malo olumikizidwa. Ngakhale izi zikuwoneka zosapeweka, pali njira zingapo zomwe zingatengedwe kuti zichepetse kapena kuthetsa kupotoza.

Chimodzi mwa njira zoyamba zopewerakuwotcherera ndi laserKupotoza ndi kusankha mosamala magawo oyenera a laser welding. Zinthu monga mphamvu ya laser, liwiro la welding, ndi kuyang'ana kwa beam ziyenera kukonzedwa bwino kuti zikwaniritse mtundu wofunidwa wa weld. Mwa kusintha magawo awa, kutentha kumatha kuyendetsedwa ndipo kusintha kwa kutentha komwe kumayambitsa kupotoza kumatha kuchepetsedwa. Kuphatikiza apo, kugwiritsa ntchito pulsed mode m'malo mwa continuous wave mode kumathandiza kuchepetsa malo omwe kutentha kumakhudzidwa ndi kusintha komwe kumachitika.

Chinthu china chofunika kuganizira ndi kapangidwe ka cholumikizira chokha. Kapangidwe, kukula ndi kapangidwe ka cholumikiziracho zingakhudze kwambiri kuchuluka kwa kusintha komwe kumachitika panthawi yakuwotcherera ndi laserKuti muchepetse kupotoka, tikukulimbikitsani kugwiritsa ntchito ma welds otakata ndikupewa ngodya zakuthwa kapena zakuthwa. Izi zimagawa kutentha mofanana komanso zimachepetsa kutentha kwambiri. Kuphatikiza apo, kugwiritsa ntchito ma welds a fillet (ma welds okhala ndi mawonekedwe opindika kapena opindika) kumathandizanso kuchepetsa kupotoka.

Kuwonjezera pa magawo olumikizirana ndi kapangidwe ka malumikizano, kusankha makulidwe a zinthu kumathandizanso kwambiri popewa kupotoka. Mapepala okhuthala achitsulo chosapanga dzimbiri amatha kupotoka chifukwa cha kutentha kwawo kwakukulu. Pofuna kuchepetsa izi, tikukulimbikitsani kugwiritsa ntchito mapepala okhuthala achitsulo chosapanga dzimbiri kapena kugwiritsa ntchito chotenthetsera kapena makina oziziritsira panthawi yothira soldering. Njira zoziziritsira izi zimathandiza kuthetsa kutentha kochulukirapo ndikuchepetsa kutentha, kuchepetsa kupotoka.

Kuphatikiza apo, kugwiritsa ntchito njira zoyenera zomangira ndi zomangira kungathandize kwambiri kupewa kusokonekera kwa laser welding. Chomangirachi chikutanthauza malo ndi kukhazikika kwa workpiece panthawi yogwiritsa ntchito welding. Ndikofunikira kuonetsetsa kuti workpiece yathandizidwa mokwanira komanso yolumikizidwa bwino kuti isasunthike kapena kupindika panthawi yogwiritsa ntchito welding. Kumbali ina, kukanikiza kumaphatikizapo kugwira workpiece pamalo ake pogwiritsa ntchito jigs kapena zida zapadera. Kukanikiza koyenera kumathandiza kusunga mulingo woyenera wa kulinganiza ndikuchepetsa mwayi wopindika.

Pomaliza, chithandizo cha kutentha pambuyo pa weld chingagwiritsidwe ntchito kuchepetsa kupsinjika kotsala ndikuchepetsa kusokonezeka. Kuphimba, kuchepetsa kupsinjika, komanso njira zosavuta zoziziritsira mpweya zimathandiza kukhazikika kwa zomangamanga zolumikizidwa ndikuchepetsa kusokonezeka. Kugwiritsa ntchito zida zapadera zochizira kutentha kungathandize kuti kutentha kuyende bwino kuti chitsulo chosapanga dzimbiri cholumikizidwa chikhale chokhazikika komanso chopanda kusinthika.

Powombetsa mkota,kuwotcherera ndi laserimapereka zabwino zambiri kuposa njira zachikhalidwe zowotcherera malinga ndi liwiro, kulondola, ndi mtundu. Komabe, kusintha kwa chitsulo chosapanga dzimbiri kumabweretsa zovuta pa njira yowotcherera ya laser. Kusokonekera kwa kuwotcherera kwa laser yachitsulo chosapanga dzimbiri kumatha kuthetsedwa bwino posankha mosamala ndi kukonza magawo owotcherera, kupanga makonzedwe oyenera a maulumikizidwe, kuganizira makulidwe a zinthu, kukhazikitsa njira zoyenera zomangira ndi zomangira, komanso kugwiritsa ntchito mankhwala otentha pambuyo pa kuwotcherera. Njirazi, kuphatikiza ndi makhalidwe enieni a chitsulo chosapanga dzimbiri, zimathandiza kuti ma weld apamwamba azikhala ndi kusokonekera kochepa.

Ngati mukufuna kudziwa zambiri zokhudza kuwotcherera pogwiritsa ntchito laser, kapena mukufuna kugula makina abwino kwambiri owotcherera pogwiritsa ntchito laser, chonde titumizireni uthenga patsamba lathu ndipo titumizireni imelo mwachindunji!
