Chophimba pamwamba pazitsulo chimapangidwa kuti chizizizira kapena kukongoletsa, kapena zonse ziwiri.The kuwotcherera msoko, osati kupeza zokwanira olowa mphamvu, komanso chofunika kuti ntchito ya ❖ kuyanika.Ndi zofunika mphamvu, ndondomeko kuwotcherera msoko ndi zitsulo unncoated n'zofanana, poganizira zofunika za ❖ kuyanika, kuwotcherera ndondomeko magawo adzakhala kusintha koyenera, ndiye kulabadira zotsatira za kukhudzana kukana ❖ kuyanika, kulola electrode indentation, ❖ kuyanika ndi matabwa mayi ndi zitsulo kasakaniza wazitsulo chizolowezi kupanga adhesions zimachitika ndi maelekitirodi.

Chitoliro chachitsulo chagalasindi kuonjezera kukana dzimbiri zitsulo, koma kanasonkhezereka wofatsa zitsulo ndi zovuta kuposa kanasonkhezereka zitsulo mbale kuwotcherera.Makamaka chifukwa cha otsika kusungunuka mfundo ya ❖ kuyanika nthaka (pafupifupi 419C), pa kuwotcherera kanasonkhezereka wosanjikiza choyamba anasungunuka ndi wodzigudubuza membala ndi kuwotcherera elekitirodi ndi kuwotcherera membala ndi kukhudzana pamwamba pa kuwotcherera panopa kugawa membala, kukhudzana m'dera kumawonjezera , kachulukidwe wamakono amachepetsa ndipo kukhudzana pamwamba pa elekitirodi ndi weldments kanasonkhezereka wosanjikiza wosanjikiza, ndi ma elekitirodi nkhope kugwirizana, copper electrode alloying (CuZn), madutsidwe magetsi ake, matenthedwe ntchito kuwonongeka.The kuwira mfundo nthaka 906C, pamene kutentha kuposa kutentha, ndi evaporation wa nthaka.Mapangidwe pores kapena ming'alu mu nugget, kutentha bwanji zone diffused mu cholumikizira zimayambitsa embrittlement ming'alu angakhale pansi pa mavuto.Mayeso adawonetsa kuti kuchepa kwa kuchuluka kwa malowedwe (10 - 26%), zolakwika zochepa zogoba;liwiro kuwotcherera ndi mkulu, zinthu kuzirala ndi osauka, otentha pamwamba ndi kulowa kwambiri, n'zosavuta osokoneza.Choncho, kuonetsetsa m'mimba mwake nugget ndi zinthu olowa mphamvu, ayenera kuyesa ntchito yaing'ono panopa, otsika kuwotcherera liwiro ndi amphamvu kunja kuzirala.Ma elekitirodi amayenera kugwiritsidwa ntchito polemba ng'oma yodzigudubuza, kuti asunge chubu chozungulira ndikuyeretsa kukula kwa electrode.
