Abstract

Analysis of heat source shape is important for comprehending Submerged Arc Welding Process. Here an attempt is made to investigate into the analytical solution of the thermal field related to a high deposition rate based process like SAW. It is assumed that a moving heat source follows Gaussian distribution. The realistic assumptions of the shape parameters are made to describe the process theoretically. It is opined that for SAW process the most appropriate heat source shape is approximately oval.

Keywords

Gaussian heat distribution; oval heat source shape; Submerged Arc Welding
