- Abstract
In this present investigation, a numerical model is carried out to study the effect of welding parameters on the temperature variations in Submerged Arc Welding process (SAW) with moving heat source model (Gaussian distribution) by using finite difference method (FDM). The obtained results from the simulation methodology are compared with experimental results and a good agreement between the experimental and the numerical results is found, with the associate degree overall proportion of error calculable to be between 6-9%, which is confirming the capability and reliability of the proposed numerical model. The numerical model is also recognized to simulate peak temperature at different locations of weldment. Finally parametric effects on temperature profiles based on numerical results are carried out for different weld parameters including welding speed and heat input. It has been shown that all those parameters are playing an essential role in affecting the temperature distribution.
