Enye yezona nzuzo ziphambili zekubanda isakhiwo esidityanisiweyo esenziwe nge-welded intsimbi yeyona milinganiselo yayo iphezulu yamandla xa ithelekiswa nobunzima. Oku kuthetha ukuba inika amandla aphezulu ngelixa ilula, nto leyo eyenza kube lula ukuyiphatha nokuyithutha ngexesha lokwakha. Ukongeza, amandla aphezulu entsimbi eyenziwe ngokubandayo avumela uyilo lwesakhiwo oluncinci nolusebenzayo oluthi lwandise indawo kwaye lunciphise ukusetyenziswa kwezinto.

Enye inzuzo ebalulekileyo yentsimbi yokwakha edityanisiweyo eyenziwe ngokubandayo kukufana kwayo kunye nokuhambelana kwayo.
