Abstract: The study of heat flow in welding is a very important phenomena as quality of weld depends on mainly heat flow through welded plate. Heat input by welding source in a limited zone and it subsequent flow into body of work piece by conduction. A limited amount of heat loss is by a way of convection and radiation. In this paper, an attempt is taken to predict transient temperature distribution through a mathematical model and the associated numerical technique considering the heat transfer and solidification of molten weld pool when it is covered with flux and without flux. The estimated temperature distribution obtained, solidification and melting and those obtained from experimental measurements compared fairly well with variation up to 3% for the peak temperatures
