The present paper is devoted to the experimental study of the mechanical behavior of high-density polyethylene structure subjected to traction andwelded by means of butt-welding process. We were based ourselves on experimental testswhich have been carried out to characterize the material studied, introducing the ductility or fragility of the beadwelded section, and understood the effect of crosshead speeds on the mechanical behavior of the weld bead. The experimental results of the welded specimens are compared with those corresponding to the base material. In this study, two crosshead speeds of 10 and 50 mm/min were applied to make the comparison.
