Study has been carried out aimed at predicting the cooling time from 1200 to 800°C (<I>t</I><SUB>12/8</SUB>) of arc welds in stainless steel using an existing heat flow model and direct measurement of the weld thermal cycle. The properties of welds in austenitic-ferritic duplex stainless steel depended on the delta (δ) ferrite content of the weld metal (WM) and the heat effected zone (HAZ). The <I>t</I><SUB>12/8</SUB> was the major cooling parameter relating to the δ-ferrite content. It was shown that the travel speed and the distribution of the heat source had negligible effect on the value of <I>t</I><SUB>12/8</SUB> in a practical welding situation. The proposed equation predicted <I>t</I><SUB>12/8</SUB> with an error of approximately 15% relative to experimental measurement.
