M'dziko lazopanga ndi uinjiniya, kuwotcherera mawanga ndi njira yofunika kwambiri yomwe imagwiritsidwa ntchito kulumikiza zidutswa ziwiri kapena zingapo zazitsulo. Chinthu chimodzi chofunika kwambiri pakuchita izi ndi kupanga dziwe la weld, lomwe limakhala lochititsa chidwi kwambiri pankhani ya makina owotcherera nut spot. M'nkhaniyi, tifufuza zamakanika momwe dziwe la weld limapangidwira pamakina apaderawa.
Kumvetsetsa Njira Yowotcherera Nut Spot
Tisanafufuze mapangidwe a dziwe la weld, tiyeni timvetsetse momwe kuwotcherera malo a mtedza. Njirayi imagwiritsidwa ntchito pophatikiza nati kapena chomangira pazitsulo zachitsulo, nthawi zambiri pamagalimoto ndi mafakitale. Ndi njira yachangu komanso yothandiza, kuonetsetsa kulumikizana kotetezeka komwe kumatha kupirira katundu wambiri.
Udindo wa Kutentha ndi Kupanikizika
Powotcherera nut spot, zinthu ziwiri zazikulu zomwe zimaseweredwa ndi kutentha ndi kupanikizika. Makinawa amagwiritsa ntchito gwero la kutentha komweko ku mtedza ndi chogwirira ntchito. Kutentha kumeneku, komwe nthawi zambiri kumapangidwa ndi mphamvu yamagetsi yomwe imadutsa muzinthuzo, kumapangitsa kuti zitsulo zomwe zili pafupi zisungunuke. Panthawi imodzimodziyo, kupanikizika kumagwiritsidwa ntchito kuti zitsimikizire kukhudzana koyenera pakati pa mtedza ndi workpiece.
Kupanga kwa Weld Pool
Dziwe la weld, chigawo chachitsulo chosungunula chomwe chimapangidwa panthawiyi, ndicho chinsinsi cha kuwotcherera kwa nati. Zimapangidwa pamene gwero la kutentha, kawirikawiri electrode, likukumana ndi mtedza ndi workpiece. Kutentha kumawonjezera kutentha kwachitsulo m'derali, zomwe zimapangitsa kuti zisungunuke.
Chitsulo chosungunuka chimasonkhanitsa pa mawonekedwe pakati pa mtedza ndi workpiece. Iyi ndi mfundo yofunika kwambiri, chifukwa ndi pamene kuphatikizika kwa zida ziwirizi kumachitika. Dziwe liyenera kukhala la kukula koyenera ndi kutentha kuti likhale lolimba komanso lolimba.
Kuwongolera ndi Kulondola
Kukula ndi mawonekedwe a weld dziwe amayendetsedwa mosamala mu nati malo kuwotcherera. Kutalika kwa nthawi ya kutentha, kugwiritsidwa ntchito kwamakono, ndi kupanikizika komwe kumagwiritsidwa ntchito zonse zimathandizira kudziwa makhalidwe a dziwe la weld. Cholinga chake ndi kupanga dziwe lomwe liri loyenera kuti likhale lolimba kuti likhale lolimba popanda splatter kapena kusokoneza kwambiri.
Solidification ndi kugwirizana
Pamene dziwe la weld limapangidwa, limaloledwa kuziziritsa ndi kulimbitsa. Pamene chitsulo chosungunuka chimalimba, chimagwirizanitsa nati ku chogwirira ntchito, kupanga mgwirizano wamphamvu wamakina. Ubale umenewu umatheka chifukwa chakuti zipangizo ziwirizi, m’malo ake osungunuka, zimasakanikirana ndi kusanganikirana pamlingo wa atomiki. Akazizira ndi kulimba, amakhala amodzi.
Mu makina owotcherera madontho a nati, kupanga dziwe la weld ndi gawo lofunikira popanga kulumikizana kolimba komanso kolimba pakati pa mtedza ndi chogwirira ntchito chachitsulo. Kupyolera mu kuwongolera kolondola kwa kutentha, kupanikizika, ndi nthawi, opanga amatha kuonetsetsa kuti dziwe la weld limapangidwa bwino, zomwe zimapangitsa kuti pakhale mgwirizano wodalirika komanso wolimba. Kumvetsetsa izi ndikofunikira kwa iwo omwe akuchita nawo ntchito zopangira zitsulo, kuwotcherera, ndi uinjiniya, chifukwa zimathandizira ntchito zambiri zamafakitale, makamaka m'magawo agalimoto ndi opanga.
