摘要：
In a submerged arc welding process, the concept of temperature distribution is essential in order to control the HAZ (heat-affected zone) 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 the conductive heat transfer of a semi infinite body. With the help of this analytical solution, the transient temperature distribution, the HAZ width, the weld bead dimensions are estimated. Good compatibility between predicted and experimental values is achieved.
