(1) Nciphisa indawo yokugquma kangangoko unako ukuze uthintele kwaye unciphise imifantu, ngaloo ndlela uphucula ubomi besixhobo.
(2) Amandla okuwelda aqinisekiswa ngokusebenzisa izixhobo zokuwelda ezinamandla aphezulu kunye neendlela ezifanelekileyo zokuwelda.
(3) Qinisekisa ukuba izinto zokuwelda ezigqithisileyo azinamatheli entlokweni yesixhobo emva kokusila, nto leyo eyenza kube lula ukugaywa komphetho. Le migaqo yahlukile kwezo zazisetyenziswa ngaphambili kwizixhobo ze-alloy ezinzima ze-multi-blade, ezazidla ngokuba noyilo lwe-groove oluvaliweyo okanye oluvaliweyo kancinci. Oku kokugqibela akukonyusanga nje kuphela uxinzelelo lwe-brazing kunye nokuqhekeka, kodwa kwenza nokuba kube nzima ukususa i-slag ngexesha lokusila, nto leyo ekhokelela ekubanjweni kwe-slag kakhulu kwi-weld kunye nokuqhekeka okukhulu. Ngaphezu koko, ngenxa yoyilo olungafanelekanga lwe-groove, izinto zokuwelda ezigqithisileyo azikwazanga ukulawulwa kwaye ziqokeleleke entlokweni yesixhobo, nto leyo ebangela ubunzima ngexesha lokusila komphetho. Ke ngoko, kufuneka kunikwe ingqwalasela ekhethekileyo xa kuyilwa izixhobo ze-alloy ezinzima ze-multi-blade.
Izinto zokuwelda kufuneka zibe nokumanzi kakuhle xa zombini i-alloy eqinileyo ixutywe ngebrashi kunye ne-substrate yentsimbi.
Kufuneka iqinisekise amandla aneleyo e-weld kubushushu begumbi kunye nobushushu obuphezulu (njengoko izixhobo ze-alloy eqinileyo kunye nee-mold ezithile zifumana amaqondo obushushu ahlukeneyo ngexesha lokusetyenziswa).
Ngelixa kuqinisekiswa ezi meko zingasentla, izinto zokuwelda kufuneka zibe nendawo yokunyibilika ephantsi ukunciphisa uxinzelelo lwebrazing, ukuthintela ukuqhekeka, ukuphucula ukusebenza kakuhle kwebrazing, kunye nokuphucula iimeko zokusebenza zabaqhubi.
Izinto zokuwelda kufuneka zibonakalise ubushushu obuphezulu kunye nobushushu begumbi ukuze kuncitshiswe uxinzelelo lwebrazing. Kufuneka zikwazi ukuhamba kakuhle kwaye zingene kakuhle, kwaye olu phawu lubaluleke kakhulu xa kusenziwa izixhobo zokusika iiblade ezininzi ze-hard alloy kunye neendawo ezinkulu zokubumba ii-hard alloy.
Izinto zokuwelda akufuneki zibe nezinto ezineendawo zokufuma eziphantsi, ukuthintela ukufuma kwezi zinto ngexesha lokufudumeza ibrazing kunye nokuchaphazela umgangatho wokuwelda.
Izinto zokutywina akufuneki zibe neentsimbi ezixabisekileyo, ezinqabileyo, okanye izinto eziyingozi kwimpilo yabantu.
