An additional experimental design was carried out to highlight the influence of the number ofthe laser beam passages on the resistance of the welded plates. It was noted that, usually, for the sameparametric conditions a certain improvement of failure force is recorded if one carries out two passages(figure 8-a) with the laser beam compared to only one passage (figure 8-b).One can appreciate that the optimal weld strength of the welded plates, for the studiedconfiguration, are obtained for the following process parameters:- laser power P = 15W;- speed of welding v [ 0.5; 0.55] m/min;- clamping pressure Pr = 0.4MPa;- a number of 2 passages of the laser beam
