Makina owotcherera apakati pafupipafupi amagwiritsidwa ntchito kwambiri popanga mafakitale.Mapangidwe a dziwe losungunuka panthawi yowotcherera ndi njira yofunika kwambiri yomwe imatsimikizira mtundu wa weld.M'nkhaniyi, tikambirana ndondomeko ya mapangidwe dziwe losungunuka mu sing'anga pafupipafupi malo kuwotcherera makina.
Choyamba, kuwotcherera pakali pano kumagwiritsidwa ntchito pamagetsi awiri, omwe amapanga kutentha kwakukulu pa malo okhudzana ndi ma electrode ndi workpiece.Izi zimapangitsa kutentha kwachitsulo kukwera mofulumira, zomwe zimapangitsa kuti pakhale dziwe laling'ono losungunuka.
Pamene mphamvu yowotcherera ikupitirira kuyenda, dziwe losungunukalo limakulirakulirabe, ndipo zitsulo zomwe zili pafupi ndi dziwelo zimayamba kufewa.Chitsulo chofewacho chimathamangira ku dziwe losungunuka chifukwa cha capillary action, yomwe imatsogolera kupanga nugget yolimba.
Panthawi yowotcherera, kutentha kwa dziwe losungunuka ndilofunika kwambiri kuti muthe kutenthetsa bwino.Ngati kutentha kuli kochepa kwambiri, nugget ikhoza kusapanga bwino, zomwe zimapangitsa kuti zikhale zofooka.Ngati kutentha kuli kwakukulu, chitsulocho chikhoza kutenthedwa kwambiri ndi kuyambitsa zolakwika mu weld.
Kuti mutsimikizire mtundu wa weld, ndikofunikira kuwongolera magawo azowotcherera monga kuwotcherera pano, nthawi yowotcherera, ndi mphamvu ya elekitirodi.Mwa kusintha magawowa, kutentha kwa dziwe losungunuka kumatha kuwongoleredwa, zomwe zimapangitsa kuti pakhale chowotcherera champhamvu komanso chodalirika.
Pomaliza, ndondomeko ya mapangidwe dziwe wosungunula mu sing'anga pafupipafupi malo kuwotcherera makina ndi ndondomeko zovuta zimene zimafunika kulamulira mosamala magawo kuwotcherera.Pomvetsetsa ndondomekoyi, tikhoza kuonetsetsa kuti weld ndi wabwino komanso kuti ntchito yowotcherera ikugwira ntchito bwino.
