Mu chitoliro chozungulirakupanga ndi ntchito, pali anatulukira zambiri kuwotcherera kwambiri ndi njira zopangira, kwambiri anathandiza kuti azikhazikika ndi chitukuko mofulumira makampani, komanso zimapangitsa kuti makampaniwa wakhala wokometsedwa mu chitukuko.Amene kumizidwa arc kuwotcherera ndi njira kuwotcherera mu kutulukira kwatsopano mu 1940, izo ndi kutsogolo kwa malo ndi chimodzimodzi Buku kuwotcherera kapena kugwiritsa ntchito slag kuteteza izo, koma si slag elekitirodi ❖ kuyanika, lakonzedwa smelting kutuluka kunja. .Zosinthidwa pambuyo pa waya, chipangizo choperekera waya chokhala ndi mbale ndi waya, waya amatumizidwa mosalekeza, waya wowotcherera amadyetsedwa mosalekeza mu granular fusible flux yophimba waya wowotcherera wa arc, zinthu zoyambira ndi gawo la mawonekedwe osungunuka ndi evaporation. Patsekeke, arc ndi khola kuyaka mu patsekeke mkati, choncho kuitana kumizidwa arc kuwotcherera.Arc imayikidwa m'chipinda chamkati.The kuwotcherera flux hopper Mumakonda dongosolo tichipeza yobereka mankhwala kudzera chitoliro kuti welded kutsogolo kwa mtundu wachiwiri kuwotcherera ntchito, ntchito waya, popeza waya akhoza mosalekeza anatumiza;Ndodo, ndodo kuti tiyenera kutentha kuwotcherera mutu anapereka kuponya, ndi ntchito anasiya, ndiyeno kusintha elekitirodi kuwotcherera.

Ndipo njira yowotcherera yotereyi poyerekeza ndi njira zina ndi mwayi waukulu, mwayi woyamba ndi wokhazikika;Ubwino wachiwiri, womwe umakwiriridwa Pansi pa kuwotcherera kwa arc, ndiye kuwotcherera kutentha ndi chitetezo champhamvu kwambiri, kuwotcherera kwapamwamba;Ubwino wachitatu, chifukwa kumizidwa arc kuwotcherera arc m'manda mu flux, kotero angagwiritsidwe ntchito lalikulu panopa, kuwotcherera dzuwa ndi mkulu.
