  ABSTRACT: Quadratic and linear models have been derived for predicting the heat-affected zone (HAZ) hardness of water cooled cast iron weldment in relation to the combined and respective values of the heat-affected zone hardness of aluminum and mild steel welded and cooled under the same conditions. It was found that the validity of the model is rooted on the fractional expression; γ/3.0749θ + γ/3.0749β + θ/3.0749β = 1. The respective deviations of the model-predicted heataffected zone hardness values of aluminum, cast iron and mild steel from the corresponding experimental values were less than 0.01% which is quite insignificant, indicating reliability of the model.
