Isakhelo kukubonelela nge-gap encinci phakathi kwee-rolls kunye nokhuseleko olongezelelweyo kwibhanti yokuhambisa.Izityibilizi zangaphandle zesakhelo ziyilelwe ukuthintela ukwakhiwa kwemathiriyeli ejikeleze isiphelo seqokobhe ezibangela ukunxitywa kwangaphambi kwexesha ukunqanda iqokobhe ngendima yokuxinana.

Isakhelo umnqamlezo amalungu isiseko amandla optimum kumlinganiselo ubunzima, ngelixa eyilelwe ukunika inkxaso eyaneleyo indima phantsi kweemeko umthwalo.Zonke iifreyimu ziyahlolwa ukuqinisekisa ukuchaneka kwemilinganiselo ephambili phambi kokuqala kwe-weld run.Imifanekiso ekhethiweyo iya kususwa kumxholo wemveliso ngamaxesha kunye nokuhlolwa okupheleleyo komgangatho kunye nokulawulwa komgangatho we-welding.
