Umsebenzi oyinhloko weUkuthethelelwa kwekhwalithiukuhlolwa kanye nokuhlaziywa kwekhwalithi ukubona ikhwalithi yokwenziwa, hlaziya izimbangela zeUkuthethelelwa Kwezinkingakanye nezinyathelo zokuvimbela, hlaziya izimbangela zeUkuthethelelwa Kwezinkinga, Beka phambili izinyathelo zokuvimbela ezisebenzayo kanye nokwenza ngcono, okuyindlela ebalulekile yokwenza ngcono futhi uqinisekise ikhwalithi yokwenziwa.
UkusukaUkwakha Izicikungabonakala ukuthi izici ezithintaImfaneloBaningi, ngaphezu kwekhwalithi yezinto zokwakha eluhlaza kunomthelela obalulekile, kepha futhi kuhlobene kakhulu nenqubo yokwelashwa nokushisa. Ngakho-ke, ukuhlaziya kanye nokucwaninga kokwakha izinkinga zekhwalithi, kuwumsebenzi ocophelela futhi oyinkimbinkimbi. Inqubo ejwayelekile yokuhlaziywa kwekhwalithi yokukhokhiswa yile:

1. Phenya isimo sokuqala, kufaka phakathi uphenyo lwezinto zokwakha kanye nenqubo evumayo. Lowo owayengaphambili kufanele azi ikhwalithi yezinto zokwenziwa ezivuthiwe, kanye nobuchwepheshe bokunsunduza nokucubungula kwezinto eziluhlaza. Okokugcina kufanele aphenye ukuthi ngabe inqubo yenqubo yokwakha inengqondo nokwenziwa kwangempela kokukhiqiza.

3 Uma kunesidingo, kudingeka ukuqhathanisa amapharamitha enqubo futhi ukutadisha nokuhlaziya izimbangela zokwakha iziphambeko.
4. Izisombululo ezihlongozwayo, ngokuya ngezimbangela ezicacile zokwakha iziphambeko, ezihlanganiswe nomkhuba wokukhiqiza, kuhlongozwa izindlela zokuvimbela nezixazululo.

Izindlela zokuhlola zokukhokhiswa kwekhwalithi zifaka phakathi: Ukuhlolwa okunamandla okunamandla, i-metallographigraph Njengoba kushiwo ngenhla, ukuhlolwa kwamandla okuphansi kungadalula iziphambeko zokukholelwa kwe-macro; Ukuhlolwa kwesakhiwo kweMetallographic kuyasiza ukutadisha nokuhlaziya izici eziyi-microscopic kanye nendlela yokwakha yesici. Ukuhlolwa kokuhlaziywa kwensimbi okuguquguqukayo kwensimbi kubaluleke kakhulu ekuhlaziyweni kokuqhekeka, ukugoqa, ukwakheka okusanhlamvu nokugeleza komugqa. Ekukhokhisweni kokuhlaziywa kwekhwalithi, kuvame ukuhlanganiswa nalokhu okungenhla.
