i think ,these parameters may affect on total weld volume& total heat
input.therefore affect on impact property.
i read in a book published by HARTFORD, that says heat input can be
calculated based on weld volume( that's reasonable) other than formule
in QW409.1.
DO YOU HAVE FORMULE FOR CALCULATING OF H.I BASED ON WELD VOLUME?
