Abstract

The present paper summarizes the experimental study of the mechanical behavior of high-density polyethylene structure welded by butt-welding process, subjected to tensile loading. In this work, we based on experimental tests in order to characterize the studied material, introducing the ductility and the fragility of the bead-welded section material, seeing the influence of the crosshead speed of 10 and 50 mm/min and taking into account the weld parameters such as the fusion temperature for a such given inner diameter. The welding parameters had a direct impact on microstructure of bead weld which itself is very heterogeneous.
