Kodi Stick Electrodes Ndi Chiyani?

Ma elekitirodi owotcherera ndi mawaya achitsulo omwe amawotchera pa zokutira mankhwala.Ndodoyo imagwiritsidwa ntchito kuchirikiza arc yowotcherera komanso kupereka zitsulo zodzaza zomwe zimafunikira kuti olowawo athe kuwotcherera.Chophimbacho chimateteza zitsulo kuti zisawonongeke, kukhazikika kwa arc, ndikuwongolera weld.Kutalika kwa waya, kuchepera kwa zokutira, kumatsimikizira kukula kwa ndodo yowotcherera.Izi zimawonetsedwa mu tizigawo ta inchi monga 3/32″, 1/8″, kapena 5/32.Kucheperako kwake kumatanthauza kuti kumafuna kucheperako ndipo kumayika chitsulo chocheperako.

Mtundu wa zitsulo m'munsi kukhala welded, njira kuwotcherera ndi makina, ndi zina zimatsimikizira mtundu wa electrode kuwotcherera ntchito.Mwachitsanzo, carbon low kapena "mild steel" imafuna ndodo yowotcherera yachitsulo yofatsa.Kuwotcherera chitsulo, aluminiyamu kapena mkuwa kumafuna ndodo ndi zida zosiyanasiyana.

Kupaka kwa flux pa maelekitirodi kumatsimikizira momwe zingakhalire panthawi yowotcherera.Zina mwa zokutira zimayaka ndi kutentha kwamoto kumapanga utsi ndikuchita ngati chishango chozungulira "dziwe" lowotcherera, kuteteza ku mpweya wozungulira.Mbali ina ya flux imasungunuka ndikusakanikirana ndi waya ndikuyandama zonyansazo pamwamba.Zonyansa izi zimatchedwa "slag."Kuwotcherera komalizidwa kumakhala kolimba komanso kofooka ngati sichoncho.Pamene welded olowa utakhazikika, slag akhoza kuchotsedwa.Nyundo yoboola ndi burashi yawaya imagwiritsidwa ntchito kuyeretsa ndikuwunika chowotcherera.

Ma elekitirodi owotcherera zitsulo atha kugawidwa ngati maelekitirodi opanda kanthu, maelekitirodi opaka kuwala, ndi ma arc otetezedwa kapena maelekitirodi okutira olemera.Mtundu womwe umagwiritsidwa ntchito umadalira zinthu zomwe zimafunikira zomwe zikuphatikizapo: kukana kwa dzimbiri, ductility, kulimba kwamphamvu kwambiri, mtundu wazitsulo zoyambira zomwe ziyenera kuwotcherera;ndi malo a weld kukhala lathyathyathya, yopingasa, ofukula, kapena pamwamba.
