Momwe Mungathanirane ndi Ma Weld Osauka mu Makina Owotcherera a Nut Spot?

Pogwiritsa ntchito makina owotcherera madontho a mtedza, kukumana ndi zowotcherera zosawoneka bwino, monga ma weld spatter kapena kuphatikizika kosakwanira, kungakhale vuto wamba. M'nkhaniyi, tikambirana zomwe zimayambitsa kuwotcherera kosauka kwa nut spot kuwotcherera ndikupereka njira zothetsera vutoli moyenera. Kumvetsetsa momwe mungathanirane ndi ma welds osauka kungathandize kuonetsetsa kuti njira yowotcherera ndi yabwino komanso kukhulupirika.

1. Zomwe Zimayambitsa Ma welds Osauka: Zowotcherera molakwika mumakina owotcherera ma nati zitha kukhala chifukwa cha zinthu zosiyanasiyana, kuphatikiza:
   • Kuthamanga kosakwanira kapena mphamvu ya electrode
   • Zowotcherera zolakwika, monga kusakwanira kwapano kapena nthawi
   • Kuipitsidwa pamwamba pa workpiece kapena electrode
   • Kuyika molakwika kapena kusakwanira bwino kwa magawo omwe akuwotcherera
   • Kusakwanira kuyeretsa workpiece pamaso kuwotcherera
2. Njira Zothetsera Zowotcherera Zosauka: Kuti muthane ndi zovuta za kuwotcherera kosauka kwa nut spot kuwotcherera, njira zotsatirazi zitha kukhazikitsidwa:

   a) Sinthani Kupanikizika kapena Mphamvu ya Electrode: Onetsetsani kuti kukakamiza kapena mphamvu ya elekitirodi yomwe imagwiritsidwa ntchito pakuwotcherera ndiyokwanira kuti mukwaniritse kupsinjika koyenera ndikulumikizana pakati pa mtedza ndi chogwirira ntchito. Sinthani zoikamo zokakamiza malinga ndi malingaliro a wopanga.

   b) Konzani Zowotcherera Zowotcherera: Unikaninso ndikusintha magawo owotcherera, kuphatikiza apano, nthawi, ndi kukula kwa nsonga ya elekitirodi, kuti muwonetsetse kuti ndizoyenera zida zenizeni komanso masanjidwe olumikizana. Funsani bukhu la zida kapena funsani upangiri wa akatswiri ngati kuli kofunikira.

   c) Onetsetsani Malo Oyera: Tsukani bwino malo a workpiece ndi electrode kuchotsa dothi, mafuta, kapena zowonongeka zomwe zingasokoneze ntchito yowotcherera. Gwiritsani ntchito njira zoyenera zoyeretsera ndi zosungunulira zomwe zimalimbikitsidwa pazinthu zenizeni.

   d) Tsimikizirani Kuyanjanitsa Kwagawo: Onetsetsani kuti magawo omwe akuwotcherera, kuphatikiza nati ndi chogwirira ntchito, ndi olumikizidwa bwino komanso otetezedwa. Kusalinganiza bwino kungayambitse kuperewera kwa weld komanso kusakanikirana kosakwanira. Pangani kusintha kofunikira kapena kuyikanso zigawozo ngati mukufunikira.

   e) Limbikitsani Kutsuka kwa Zogwirira Ntchito: Musanawotchere, onetsetsani kuti malo ogwirira ntchito ayeretsedwa bwino kuti achotse masikelo, dzimbiri, kapena oxide. Gwiritsani ntchito njira zoyenera zoyeretsera monga kupukuta waya, kugaya, kapena kuyeretsa mankhwala kuti mulimbikitse kumamatira kwa weld.

3. Kusamalira ndi Kuyang'anira Nthawi Zonse: Khazikitsani pulogalamu yokonza makina owotcherera ma nati. Yang'anani ndikutsuka ma elekitirodi nthawi zonse, fufuzani ngati akutha kapena kuwonongeka, ndikusintha ngati kuli kofunikira. Onetsetsani kuti makinawo asinthidwa ndikugwira ntchito molingana ndi zomwe akulimbikitsidwa.

Kukumana ndi ma welds osowa m'makina owotcherera mtedza kumatha kuthetsedwa pothana ndi zomwe zidayambitsa ndikukhazikitsa njira zoyenera. Mwa kusintha kukakamiza kapena mphamvu ya electrode, kukhathamiritsa magawo owotcherera, kuonetsetsa kuti malo ali oyera, kutsimikizira kulondola kwa magawo, ndikuwonjezera kuyeretsa kwa ma welds, mtundu ndi kukhulupirika kwa ma welds zitha kusintha kwambiri. Kusamalira nthawi zonse ndi kuyang'anitsitsa zida kumathandizanso kuti ntchito yowotcherera ikhale yosasinthasintha komanso yodalirika. Potsatira malangizowa, ogwira ntchito amatha kuthana ndi zowotcherera bwino komanso kukhala ndi zotsatira zabwino kwambiri pakuwotcherera ma nati.
