1. Kuwotcherera kuyenera kukhala kolimba komanso kodalirika, ndipo solder pamtunda wakunja wa zigawozo ziyenera kudzazidwa, osasiya mipata.
2. Msoko wowotcherera uyenera kukhala waukhondo komanso wofanana, ndipo palibe zolakwika monga ming'alu, mabala, mipata, kuwotcha, ndi zina zotero.Sipayenera kukhala ndi zolakwika monga slag inclusions, pores, weld tokhala, maenje, ndi zina zotero pamtunda wakunja, ndipo mkati mwake sayenera kuwonekera.
 
3. Pamwamba pa zigawozo ziyenera kusalala ndi kupukutidwa pambuyo pa kuwotcherera, ndipo mtengo wa roughness wa pamwamba ndi 12.5.Pamalo owotcherera mu ndege yomweyo, pasakhale zotuluka zowoneka bwino ndi zonyowa pamtunda pambuyo pa chithandizo.
4 Ntchito yowotcherera iyenera kupanga njira yothetsera vuto la kuwotcherera momwe mungathere.Payenera kukhala tooling pamene kuwotcherera ndipo palibe mapindikidwe mbali chifukwa kuwotcherera amaloledwa.Ngati ndi kotheka, workpiece ayenera kukonzedwa pambuyo kuwotcherera.Sonkhanitsani molingana ndi zofunikira za zojambulazo, ndipo palibe malo osowa, olakwika, kapena olakwika omwe amaloledwa.
5. Pofuna kupewa kuoneka kwa pores kuwotcherera, zigawo zowotcherera ziyenera kutsukidwa ngati pali dzimbiri, madontho a mafuta, ndi zina zotero.

6. Kuti mpweya wa argon uteteze bwino dziwe lowotcherera ndikuthandizira ntchito yowotcherera, mzere wapakati wa tungsten electrode ndi workpiece yowotcherera iyenera kukhala ndi ngodya ya 80 ~ 85 °.Ngodya pakati pa waya wodzaza ndi pamwamba pa chogwirira ntchito iyenera kukhala yaying'ono momwe mungathere, nthawi zambiri pafupifupi 10 °.
7. Nthawi zambiri oyenera kuwotcherera mbale woonda m'munsimu 6mm, ndi makhalidwe a mawonekedwe okongola kuwotcherera msoko ndi mapindikidwe ang'onoang'ono kuwotcherera.
