This study deal with temperature destitution generated during Wire-Electrical Discharge Machining (WEDM) results in the large heat-affected zone. This large localized heat- affected zone can becreate micro-cracks, which will reduce the strength as well as surface quality of workpiece material. This paper illustrates the effect of process parameters for heat flux which is the major factor for large localized heat- affected zone on SAILMA 350 and Titanium materials with Zinc coated Brass wire material. The symmetric thermal model has been created and solved using Creo Software. A transient type thermal analysis by using a Gaussian-equation for Distributed heat source, which is dependent on material properties with respect to temperature has been carried out for heat flux. The heat flux is decreased with the increasing the value of pulse-on-time, peak-current, and servo-voltage,while it is increased with the increase of pulse-off time. The heat flux(Q) value for SAILMA350 is 37.42 W/m2 to 2045.40 W/m2 and for Titanium material 32.21 W/m2 to 2084.48 W/m2 which shows that SAILAM350 material have less heat flux range than Titanium material. Resulting improve the surface quality by localization of heating zone.
