Abstract
Arc length is an important variable affecting the heat flow in welding. In the present paper, a three-dimensional transient finite element analysis on heat flow in arc welding under varying arc length conditions have been presented The problem was solved by considering the important factors that influence the heat transfer in arc welding, like temperature dependent material properties, enthalpy and stirring effect in molten pool. To reduce the computational time, the finer mesh was generated where the temperature gradient was too high and gradually mesh size was increased away from the heat source. Temperature distribution in the plate and variations of temperature along the cross-section at two positions of the arc for three arc radii were plotted for comparison.
