Kodi Kupanikizana Kuwotcherera Ndikofunikira Pakatikati-Frequency DC Spot Welding?

M'malo apakati-frequency DC kuwotcherera, ntchito yowotcherera yowotcherera imakhalabe mutu wofunikira kwambiri.Nkhaniyi ikufotokoza za kufunika kwa kuwotcherera mphamvu, zotsatira zake pa ntchito yowotcherera, ndi zinthu zomwe ziyenera kuganiziridwa mosamala.

Kuwotcherera ndi njira yovuta yomwe imaphatikizapo kuphatikiza zidutswa ziwiri zazitsulo pogwiritsa ntchito kutentha ndi kupanikizika.Ngakhale kufunika kwa kutentha mu njirayi kumadziwika kwambiri, ntchito ya kuwotcherera kuthamanga nthawi zambiri imakhala yochepa.Kuwotcherera kwapakati pafupipafupi kwa DC, kukakamiza komwe kumagwiritsidwa ntchito pakuwotcherera kumatha kukhudza kwambiri mtundu ndi kukhulupirika kwa cholumikizira chowotcherera.

Chimodzi mwazifukwa zazikulu zomwe kuwotcherera kuli kofunikira ndikukokera kwake pakukhudzana kwamagetsi pakati pa zida zogwirira ntchito.M'malo owotcherera apakati pafupipafupi a DC, kuthamanga kwanthawi zonse kwachindunji kumadutsa pazogwirira ntchito, kumapangitsa kukana ndikutulutsa kutentha.Ubwino wa kukhudzana kwa magetsi pakati pa zogwirira ntchito umakhudzidwa mwachindunji ndi kukakamizidwa komwe kumagwiritsidwa ntchito.Kupanikizika kosakwanira kungapangitse kuti magetsi asagwirizane bwino, zomwe zimapangitsa kutentha kosafanana ndi kuwotcherera kofooka.

Kuphatikiza apo, kukakamiza kuwotcherera kumagwira ntchito yofunika kwambiri kuti pakhale chitsulo chosasinthika, chomwe ndi dziwe lachitsulo losungunuka lomwe limapangidwa powotcherera.Kupanikizika kumathandizira kuonetsetsa kuti zogwirira ntchito zimagwiridwa molimba, zomwe zimalola kugawidwa kofanana kwa kutentha ndi kupanikizika pamtunda.Kufanana kumeneku ndikofunikira kuti mupange ma welds amphamvu, olimba omwe amakwaniritsa miyezo yamakampani ndi chitetezo.

Mphamvu ya kuwotcherera kuthamanga sikuli kokha ku khalidwe la weld olowa.Zimakhudzanso mphamvu yonse ya kuwotcherera.Kupanikizika kosakwanira kungayambitse nthawi yayitali yowotcherera ndikuwonjezera mphamvu zamagetsi, zomwe zimakhudzanso kutsika mtengo kwa ntchito yowotcherera.

Pali zinthu zingapo zomwe ziyenera kuganiziridwa pozindikira kukakamizidwa kowotcherera komwe kumagwiritsidwa ntchito.Makulidwe azinthu, mtundu wazitsulo zomwe zikuphatikizidwa, kukula kwa ma elekitirodi ndi mawonekedwe, ndi makina owotcherera onse amatenga gawo pofotokozera magawo oyenera okakamiza.Ogwiritsa ntchito kuwotcherera ayenera kuphunzitsidwa kuzindikira zizindikiro za kupanikizika kosakwanira kapena kopitilira muyeso ndikusintha zofunikira kuti akwaniritse mtundu womwe akufuna.

Pomaliza, kukakamiza kuwotcherera ndikofunikira mosakayikira pamawotchi apakati pafupipafupi a DC.Zimakhudza mwachindunji kukhudzana kwamagetsi, mapangidwe a weld nugget, ndi mphamvu yonse ya kuwotcherera.Kuti akwaniritse ma welds apamwamba kwambiri komanso odalirika, ogwira ntchito kuwotcherera ayenera kumvetsetsa udindo wa kukakamizidwa ndi kuyanjana kwake ndi magawo osiyanasiyana owotcherera.Pochita zimenezi, angathe kuonetsetsa kuti ntchito zawo zowotcherera zikugwirizana ndi miyezo yofunikira ndikupanga zolumikizira zolimba, zolimba.
