Abstract
The present paper includes the descriptions of the overlap theory and the welding mechanism, the formulation of relevant mathematical equations, and the parametric analysis of the pulsed laser seam-welding (PLSW) process. The PLSW process is simplified by strategic control of identified major process parameters, such as the mean laser power, the average peak power density, the pulse energy and the traversing speed. An experimental analysis has also been made in the study to investigate systematically the effects of the above-mentioned laser parameters on heat flow so that the controlled pulsed laser welding of materials can be carried out.
