Thermal Study for Optimization of the Thermomechanical Welding Butt Fusion Process of the PEHD Tubes (PE100)

Today, high-density polyethylene (HDPE) is the frequently used polymer in the world for public water and gas distribution, and also for the disposal of wastewater. The welding butt fusion technique of polyethylene tubes (HDPE) is that most chosen in the thermoplastic industry given its efficiency and advantages over other processes and through which the mechanical behavior of the welding can approach that of the original materials. We focus our study in this document on the study of distribution and the effect of temperature at the welding juncture, modified welding parameters: heating temperature, heating time and welding force (for fixing the other welding parameters). The issue of this article is the control of the temperature and the thickness of the molten zone allows a partial improvement in a technical origin of the welding joint’s quality.
