Monga chigawo chachikulu mu zomangira, ntchito ya mtedza imagwirizana kwambiri ndi malo omwe akugwiritsidwa ntchito. Mtedza wazinthu zosiyanasiyana, mawonekedwe ake, ndi chithandizo chapamwamba amatha kutengera momwe amagwirira ntchito. Kumvetsetsa izi ndikofunikira pakusankha kwazinthu komanso kukulitsa msika wamalonda akunja.
Kuchokera kuzinthu zakuthupi, mtedza wa carbon steel, chifukwa cha mphamvu zawo zapamwamba komanso zotsika mtengo, zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga kupanga makina ndi msonkhano wamagalimoto. Mtedza wachitsulo chosapanga dzimbiri, womwe umalimbana bwino ndi dzimbiri, ndiye njira yabwino kwambiri yogwiritsira ntchito uinjiniya wamankhwala, uinjiniya wam'madzi, ndi malo achinyezi. Amayamikiridwa makamaka pokonza chakudya ndi zida zamankhwala chifukwa chaukhondo komanso kulimba kwawo. Kuphatikiza apo, mtedza wa copper alloy, chifukwa chakuwongolera kwawo kwamagetsi komanso kukana kusokoneza ma electromagnetic, amagwiritsidwa ntchito kwambiri pazida zamagetsi ndi makina amagetsi.
Zofunikira pakugwira ntchito kwa mtedza pamalo ogwirira ntchito zimakhudza mwachindunji kusankha kwawo. M'malo otentha kwambiri-pamafunika kutentha-chitsulo chosamva kutentha kapena mtedza wapadera wa alloy kuti zitsimikizire kukhazikika kwa ulusi wolumikizira. Kumalo otsika-kutentha, kulimba kwa zinthu ndikofunikira kwambiri kuti pasakhale ngozi yosweka. Kwa zinthu zowononga kwambiri, monga asidi{6}}zotha kutha kapena malo opopera mchere, njira zothira pamwamba (monga galvanizing kapena Dacromet coating) zingathandize kwambiri kuti mtedza usachite dzimbiri. M'gawo lazamalonda akunja, kusanthula malo ogwirira ntchito a mtedza ndi gawo lalikulu la kulumikizana kwamakasitomala. Ogula nthawi zambiri amatchula zofunikira potengera momwe amagwirira ntchito pamisika yomwe akufuna. Mwachitsanzo, zida zamafuta ku Middle East zimafunikira-kutentha kwambiri komanso{11}}kuthamanga kwambiri, pomwe malo akunja a m'mayiko a Nordic amatsindika za{12}}zoletsa kuzizira ndi{13}}zoletsa kuterera. Otsatsa omwe angagwirizane bwino ndi zofunikira zachilengedwezi sikuti amangowonjezera kupikisana kwazinthu komanso amalimbikitsa makasitomala kukhulupirirana ndikulimbikitsa{15}}mgwirizano wanthawi yayitali.
Mwachidule, malo omwe ali ndi mtedza amasankha zinthu zomwe amasankha, kukonza, komanso momwe alili pamsika. Ochita zamalonda akunja akuyenera kumvetsetsa mozama zinthu zomwe zikugwirizanazi ndikupatsa makasitomala upangiri waukadaulo ndi mayankho osinthika kwambiri kuti apeze mwayi wampikisano pamsika wapadziko lonse lapansi.
