“…However, the temperature of the points away from the (a) (b) Another reason behind temperature differences may be attributed to the effect of phase transformation on carbon steel. Rate of solid state phase transformation in the different regions away from the steel's fusion absorbs a proportion of heat source energy [47]. It is also worth mentioning that the rate at which the temperature gradient becomes constant through the thickness (Fig.…”

“…In this study, it was found that the measured temperatures at interface are less than simulated results because the viscoelastic dissipation diminishes as the material heats above its glass transition temperature. Attarha and Sattari-Far [6] implemented three dimensional finite element simulations in gas tungsten arc welding to predict the temperature distribution in thin welded plates. The results provide good evidence for prediction of the Heat Affected Zone (HAZ).…”

“…This close approximation of the peak temperature was due to the Goldak heat source model used [14], which closely portrays the heat source in the experiment and because it also applied accurate values of this heat source; therefore, when the simulated heat source is at the location of where the workpiece is under analysis an error of less than 1% was obtained. Figures 9 and 10 show the temperature gradients obtained in the simulated welding when the heat source is at the center of the plate.…”

“…where qf and qr are the volumetric energy distributions before and after the torch (W/m 3 ), and ff and fr are the fractional factors of the distributions of the accumulated heat before and after the torch [14] ( Figure 1). Additionally, U, I, η are parameters directly linked to the welding procedures, while b and d are the geometric parameters of the heat source and can be determined by metallographic examination.…”
