The aim of this experimental work is the joining of similar materials of High Density Polyethylene (HDPE) using the friction stir welding process. A Full-factorial design was used as a statistical approach to analyze the effect of processing parameters on mechanical behavior of welded joint. The welding parameters considered in this study were rotational speed in five levels and traverse speeds in three levels. The strength of welded samples was characterized by tensile test. In addition, temperature measurements were carried out to determine the peak temperature in the joining zone. The results have showed the dependence of tensile strength and peak temperature on rotational speed. A maximum tensile strength was achieved at optimum rotational speed value. Moreover, the analysis of variance (ANOVA) indicates that rotational speed is the most influenced parameter in strength of joints.
