In this study, a theoretical approach of the remote welding process has been developed and discussed. The study obtains numerically the melting boundaries of different heat source angles, based on an analytical calculation of the keyhole depth. The approach considers the dominant process parameters of the laser power, the welding speed and the inclination of the laser beam on the workpiece surface. The geometrical particularities of the beam spot, due to the different inclination of the laser beam upon the processing plane, have also been considered in a previous study of the authors. The theoretical results present good agreement when compared with experimental data obtained from a remote welding system (RWS) on lap welding of AISI 304 stainless steel, thin sheets.
