The Influence of Power and Velocity of the Heat Source on Temperature Distribution in Plate Welding Problems
Abstract
The main objective of this study is to compare results obtained from some widely used simplified analytical formulas of plate welding problem to results obtained from numerical analysis of this problem based on the solution of transient three-dimensional heat conduction equation with the heat source modeled by Gaussian function. In simplified formulas, peak temperature of the thermal cycle and cooling time from 800 to 500 degrees C are proportional to the ratio of the power and the velocity of the heat source. Therefore, special attention is paid to the variation of the solution due to change in values of these two input parameters while their ratio is kept constant.
