Chitoliro ichi chimakwirira magiredi angapo a carbon ndi alloy steel mechanical chubing, mwina kutentha kapena kuzizira.Chitsulo chomwe chimagwiritsidwa ntchito mu chubu chamakina chimatha kuponyedwa mu ingots kapena chikhoza kuponyedwa mu strand cast.Pamene zitsulo zamagulu osiyanasiyana zimatsatiridwa motsatizana, chizindikiritso cha zinthu zosinthira zimafunikira.Tubing yopanda msoko ndi chinthu chopangidwa ndi tubular chopangidwa popanda msoko wowotcherera.Nthawi zambiri amapangidwa ndi zitsulo zotentha zogwirira ntchito, ndipo ngati kuli kofunikira, pomaliza kuzizira kozizira kotentha kopangidwa ndi tubular kuti apange mawonekedwe ofunikira, miyeso ndi katundu.

Machubu ayenera kuperekedwa m'mawonekedwe otsatirawa: ozungulira, apakati, amakona anayi ndi magawo apadera.Kuwunika kwa kutentha kudzapangidwa kuti mudziwe kuchuluka kwa zinthu zomwe zatchulidwa.Ngati njira zachiwiri zosungunula zikugwiritsidwa ntchito, kusanthula kwa kutentha kudzapezedwa kuchokera ku ingot imodzi yosungunuka kapena chinthu cha ingot imodzi yosungunula ya kusungunula koyambirira.Chitsulocho chiyenera kuphimbidwa ndi filimu ya mafuta musanapangike kuti muchepetse dzimbiri ngati mwatchulidwa
