Pakupanga ndi kusonkhanitsa, kuwotcherera pamalo kumagwira ntchito yofunika kwambiri popanga kulumikizana mwamphamvu komanso kodalirika pakati pa zida zachitsulo. Chofunikira kwambiri pamakina owotcherera mawanga ndi ma elekitirodi a nati omwe amagwiritsidwa ntchito powotcherera malo apakati pafupipafupi. Nkhaniyi ikufotokoza za kamangidwe ka electrode ya nati, ndikuwunikira kufunikira kwake pakuwotcherera.
- Chidule cha Mid-Frequency Spot Welding
Mid-frequency spot welding imayima ngati njira yosunthika yolumikizira zitsulo m'mafakitale, kuyambira zamagalimoto mpaka zakuthambo. Kusiyanitsa kwake ndiko kugwiritsa ntchito mphamvu yapakati yomwe imagwera pakati pa mafunde otsika kwambiri komanso othamanga kwambiri. Njirayi imatsimikizira kuti pali mgwirizano pakati pa khalidwe la weld ndi mphamvu zamagetsi.
- Udindo wa Nut Electrode
Nati elekitirodi, gawo lofunikira la makina owotcherera apakati pafupipafupi, amathandizira kwambiri pakuwotcherera. Imagwira ntchito ngati cholumikizira, imathandizira kuyenda kwapano kupita ku workpiece. Ma electrode a nati amapangidwa kuti azigwira nati ndi chogwirira ntchito palimodzi mwamphamvu, kuwonetsetsa kuti zikugwirizana bwino panthawi yowotcherera.
- Kapangidwe Kapangidwe
Mapangidwe a nut electrode ndi dongosolo lopangidwa mwaluso lomwe limakwaniritsa magwiridwe ake. Nthawi zambiri imakhala ndi zigawo izi:
a. Electrode Cap: Ichi ndi gawo lapamwamba kwambiri la nati elekitirodi yomwe imakumana mwachindunji ndi workpiece. Nthawi zambiri amapangidwa kuchokera ku zinthu zolimba komanso zosagwira kutentha kuti zipirire kupsinjika kwa kutentha ndi makina.
b. Chosungira Mtedza: Chokhala pansi pa kapu ya elekitirodi, chosungira mtedzacho chimapangidwa kuti chigwire bwino mtedzawo. Imawonetsetsa kuti mtedzawo umakhala wosasunthika panthawi yowotcherera, kuletsa kusalumikizana kulikonse komwe kungasokoneze ubwino wa weld.
c. Shank: Shank imagwira ntchito ngati kulumikizana pakati pa electrode ya nati ndi makina owotcherera. Ndi gawo lofunikira lomwe limanyamula mphamvu zowotcherera kuchokera pamakina kupita ku kapu ya electrode. Shankyo imapangidwa kuchokera ku chinthu chowongolera chokhala ndi matenthedwe apamwamba kuti achepetse kutaya mphamvu.
- Mfundo Zazikulu Zopangira
Kupanga ma elekitirodi a mtedza kumafuna kuganizira mozama zinthu zosiyanasiyana:
a. Kusankha Zinthu: Kusankha kwa zida za kapu ya elekitirodi, chosungira nati, ndi shank zimakhudza kwambiri kulimba kwa ma elekitirodi, kukana kutentha, komanso kusinthasintha kwake. Zida zodziwika bwino zimaphatikizapo ma aloyi amkuwa ndi zitsulo zowumbidwa.
b. Kuwongolera Kutentha: Kutentha kwachangu ndikofunikira kuti tipewe kutenthedwa kwa zigawo za electrode. Njira zoziziritsira zokwanira, monga kuyendayenda kwa madzi, nthawi zambiri zimaphatikizidwa mu kapangidwe ka electrode.
c. Kuyanjanitsa: Mapangidwe a chotengera mtedza awonetsetse kulumikizana bwino pakati pa nati ndi chogwirira ntchito, kuteteza kusuntha kulikonse komwe kungapangitse kuwotcherera kosagwirizana kapena kolakwika.
Pamalo owotcherera apakati pafupipafupi, ma elekitirodi a nati amakhala ngati gawo lofunikira koma lomwe nthawi zambiri silimanyalanyazidwa. Kapangidwe kake kovutirapo komanso kapangidwe kake kolingalira bwino kumakhudza kwambiri momwe kuwotcherera kumagwirira ntchito komanso mtundu wa ma welds omaliza. Pamene mafakitale akupitilizabe kufuna kulumikizana mwamphamvu komanso kodalirika, kumvetsetsa ndikuwongolera kapangidwe ka ma elekitirodi a nati kumakhalabe kofunikira kuti akwaniritse ma welds okhazikika komanso apamwamba kwambiri.
