Amacandelo akhiwe ngokwezifiso, ngenxa yeefom zabo ezizodwa kunye nobunzima besakhiwo, bajongene nemingeni emininzi ekugcineni ukuchaneka ngexesha lokuvelisa. Ukuchaneka kwala macandelo kuphenjelelwa zizinto ezininzi ezinxulumeneyo, kubandakanywa umgangatho wezinto eziphathekayo, iinkqubo zokuvelisa, ukusebenza kwezixhobo, ubuchule bokusebenza, kunye neemeko zokusingqongileyo. Ukuqonda ezi mpembelelo zingundoqo ekuveliseni amacandelo achanekileyo aphezulu ahlangabezana nemigangatho engqongqo yoshishino.
Isiseko sokuchaneka siqala ngezinto ezisemgangathweni eziphezulu. Naluphi na ulwahlulo ekubunjweni kweekhemikhali, i-microstructure, okanye i-mechanical properties ingakhokelela kwi-deformation, i-crack, okanye ezinye iziphene ngexesha lokucubungula, ukuphazamisa ngokuthe ngqo ukuchaneka kwe-dimensional. Ukukhetha izinto ezinobunzima obuhambelanayo, amandla, kunye nokuzinza kubaluleke kakhulu ekuqinisekiseni ukuchaneka kokugqibela kwecandelo.
Iinkqubo zokwenziwa kwemveliso nazo zidlala indima ebalulekileyo. Amalungu amile ngokwesiko ahlala efuna imisebenzi emininzi njengokuqengqeleka, ukolula, ukusika, ukuwelda, okanye ukuhlanganisa. Iiparamitha ezinje ngeqondo lobushushu, uxinzelelo, isantya, kunye nolandelelwano lwe-welding kufuneka zilawulwe ngononophelo, njengoko ukutenxa okuncinci kunokubangela ukugqwetheka okanye ukungahambi kakuhle komphezulu. Ukuseka isicwangciso senkqubo ephuculweyo kunye nokubambelela ngokungqongqo kuyo kuqinisekisa ukuba amacandelo afezekisa ukunyamezela kwawo okuyiliweyo kunye nokugcina umgangatho ophezulu.
Ukuchaneka kwezixhobo kunye nokuzinza kubaluleke ngokulinganayo. Oomatshini abafana nabasiki, oomatshini bokuwelda, kunye noomatshini boluleko kufuneka balinganiswe ngokufanelekileyo kwaye bagcinwe, njengoko izixhobo ezigugileyo okanye ezingazinzanga zizisa iimpazamo kwinkqubo yokuvelisa. Ukugcinwa rhoqo kunye nokutshintshwa kwangethuba kwamacandelo omatshini abalulekileyo kuyimfuneko ukugcina ukusebenza okuhambelanayo kunye nokufezekisa iziphumo ezichanekileyo.
Isakhono somqhubi kunye nokwazisa yenye into ebalulekileyo. Kwanangezona zinto zisemgangathweni kunye neenkqubo, iimpazamo ezenziwa ngabantu zisenokwenza kube lula ukuchaneka. Abaqhubi abanezakhono abaziqondayo iimfuno zomgangatho kwaye balandele iindlela ezifanelekileyo zokunciphisa umngcipheko weempazamo kwaye baqinisekise ukuba imveliso ihlangabezana nemigangatho engqongqo. Uqeqesho kunye nokukhuthaza inkcubeko yoxanduva olusemgangathweni kubalulekile ukugcina iziphumo ezingaguqukiyo.
Ekugqibeleni, iimeko zokusingqongileyo zichaphazela kakhulu ukuchaneka. Ukuguquguquka kweqondo lobushushu kunokubangela ukwanda kwemathiriyeli okanye ukucutheka, ngelixa ukufuma okuphezulu kunokukhokelela ekufunxeni kokufuma kunye nokutshintsha kwe-dimensional. Ukungcangcazela kunye nengxolo ngexesha lokucubungula kunokuphazamisana nokuchaneka. Ukulawula indawo yemveliso, kubandakanywa ubushushu obuzinzileyo, ukufuma okuphakathi, kunye nokungcangcazela okuncinci, kubalulekile ekugcineni ukuchaneka kwecandelo kuwo wonke umjikelo wokuvelisa.
Ukuqukumbela, ukuchaneka kwamacandelo akhiwe ngokwesiko kumiselwa ngokudityaniswa komgangatho wezinto eziphathekayo, ulawulo lwenkqubo, ukusebenza kwezixhobo, ubuchule bomqhubi, kunye nokuzinza kokusingqongileyo. Ukufumana ukuchaneka okuthe gqolo okuphakamileyo kufuna indlela ebanzi, apho inqanaba ngalinye lemveliso lilawulwa ngononophelo ukuze kuqinisekiswe ukuba amacandelo ahlangabezana nokunyamezelana okungqongqo kwaye asebenze ngokuthembekileyo kwizicelo ezijoliswe kuzo.
