摘要：

In this study we have used dimensional analysis to solve the heat equation inside an experimental laser welding setup The solution for the heat equation is based on the assumption that heat energy diffuses equally on both sides of the laser beam axis and that the temperature along the axis through which the laser beam moves is constant The amount of heat energy delivered by the laser to the keyhole is analyzed using the Boubaker polynomial expansion scheme BPES (C) 2010 Elsevier Ltd All rights reserved
