One problem that has arisen with very low sulphur steels is a phenomenon known as 'cast to cast variation' or 'variable penetration'. The weld pool in a low sulphur steel (0.005%) tends to be wide with shallow penetration; a steel with sulphur over some 0.010% has a narrower, more deeply penetrating weld bead.
