Prediction of Weld Bead Parameters, Transient Temperature Distribution & HAZ Width of Submerged Arc Welded Structural Steel Plates

Abstract:

In submerged arc welding process, concept on temperature distribution is essential in order to control HAZ dimensions and get the required bead size and quality. In this paper, an analytical solution for moving heat source with Gaussian distribution of inside volume of central conicoidal shape is derived. Heat transfer in welded plates during welding is assumed to be conductive heat transfer of a semi infinite body. With the help of this analytical solution, transient temperature distribution, HAZ width, weld bead dimensions are estimated. Good agreements between predicted and experimental values are achieved.
