Mfundo yogwirira ntchito ndi kapangidwe ka ndodo yowotcherera

Kufunika kwa chitsulo m'dziko lamakono kukuchulukirachulukira, ndipo zinthu zambiri zachitsulo zomwe zimagwiritsidwa ntchito tsiku ndi tsiku zimapangidwa, zomwe zimafunika kulumikizidwa ndi makina olumikizira magetsi. Gawo lofunika kwambiri pa njirayi ndi electrode kapena ndodo yolumikizira. Mu ndondomeko yolumikizira arc, electrode imachita magetsi pamalo otentha kwambiri, kenako imasungunuka, ndipo pamapeto pake imayikidwa pamalo olumikizirana a zigawo zolumikizira. Sankhani ndodo yolumikizira yogwirizana malinga ndi zinthu zomwe zili m'zigawo zolumikizira. Electrode imapangidwa ndi pakati pa chitsulo chamkati ndi chophimba chakunja. Pakati pa zolumikizira imapangidwa ndi waya wachitsulo wokhala ndi mainchesi ndi kutalika kodziwika, komwe kumatenthedwa ndikusungunuka poyambitsa magetsi, ndipo pamapeto pake kumadzazidwa.
Kusiyana pakati pa zinthu zogwirira ntchito kuti apange weld yolumikizira zinthu zogwirira ntchito. Chitsulo cha kaboni, chitsulo cha alloy ndi chitsulo chosapanga dzimbiri ndi zinthu zazikulu zogwirira ntchito zowotcherera. Kuti zikwaniritse zofunikira zowotcherera, pali zofunikira zenizeni za mtundu wa zinthu zogwirira ntchito ndi mitundu ya zinthu zachitsulo, komanso pali malamulo okhwima okhudza kuchuluka kwa zinthu zina zachitsulo. Izi zili choncho chifukwa kuchuluka kwa zinthu zachitsulo zomwe zili mu weld core kudzakhudza kwambiri mtundu wa weld.

Pamene munthu akusangalala ndi kukhazikika kwa mlatho wachitsulo, kutalika kwa ngalande, ndi kukongola kwa sitima yaikulu panyanja, ndikofunikira kuzindikira ndodo zazing'ono zosawerengeka zolumikizira zomwe zimathandizira pakupanga kwawo. Ndodo yolumikizira ikayatsidwa, imakhala ndi mphamvu zogwirizanitsa zigawo zambiri zachitsulo kuti ipange kapangidwe kogwirizana. Ndodo yolumikizira imagwirizanitsa magawo osawerengeka, imagwirizanitsa zigawo zobalalika, ndikulimbitsa zigawo zoonda. Ndi gwero la mphamvu zatsopano, zowala bwino kulikonse komwe zimayaka.
