Kubavelisi bensimbi, ukhetho lwale alloy alukho nje isigqibo sokuthengwa kwempahla kodwa ipharamitha yenkqubo ebalulekileyo. Ichaphazela ngokuthe ngqo iipropathi zoomatshini, i-weldability, kunye nokuxhathisa ukubola kwemveliso yokugqibela. Ukuqonda ama-nuances phakathi kweendlela zokuvelisa, ukucaciswa kweekhemikhali, kunye neemfuno zokuphatha kubalulekile ekuphuculeni ukusebenza kwevenkile enyibilikayo.

Ngubani ofanele asebenzise le mveliso? Le ngxubevange icetyiswa ngokukodwa kubenzi bentsimbi engatyiwa, amacandelo emoto, oomatshini abanzima, kunye neeprojekthi zeziseko ezingundoqo ezifuna imathiriyeli yokusebenza okuphezulu. Ukuba iithagethi zakho zemveliso zibandakanya imida engqongqo yekhabhoni kunye neempawu eziphezulu zoomatshini, esi sisongezo esiyimfuneko.

Ukuya phambili, vavanya iqhinga lakho langoku le-alloying ngokuchasene neenkcukacha zemveliso yakho. Qinisekisa ukuba amaqabane akho othungelwano lonikezelo anokuzisa rhoqo amanqanaba ekhemikhali achanekileyo afunekayo kwizicelo zakho. Beka phambili ababoneleli ababonelela ngesatifikethi somgangatho owomeleleyo kunye nenkxaso yobugcisa ukukhusela imfezeko yemveliso yakho. Ngokusebenzisa ibakala elifanelekileyo le ikhabhoni ephantsi ye-ferro manganese, ubeka imisebenzi yakho ukuze ihlangabezane neemfuno ezingqongqo zembonakalo yemizi-mveliso yanamhlanje.
