“…[27]. Thermoplastics can be joined by processes involving heat conduction, radiation (electromagnetic radiation) [28], or laser welding, and by mechanical friction under vibration and rotation [29]. The main purpose of this work is to contribute to the advancement of the knowledge of the joining by friction stir welding of these two semi-crystalline thermoplastics.…”

This work presents the results of the Friction Stir Welding (FSW) for two dissimilar thermoplastic polymers: Polypropylene (PP) and ultra-high molecular weight polyethylene (UHMWPE), under butt welding position. The preliminary results show poor welding, consequently, bad mechanical properties; nevertheless, introducing a self-designed and constructed fixed aluminum shoulder and determination of the best FSW parameters, such as advance speed, rotation speed, preheating or no preheating, leads to an improvement on the welding results. Tensile tests for the welded dissimilar specimens PP-UHMWPE, have revealed as high as 80% of welding efficiency in regard the original base materials. Furthermore, measures of microhardness along the welded zone and around were performed; together with the analysis of fracture behavior under tensile tests, in order to deduce the generalities of effect-cause in the improvement of mechanical properties, which are related to the glassy transition temperature of both thermoplastics, the molecular diffusion in liquid state and the process parameters.

“…Mechanical friction welding is split into multiple categories which all depend on the relative motion between two parts to generate frictional heat. The arrangement of relative motion, frequency and amplitude are the differences among these processes (Bindal et al, 2021).…”

“…This study shows that RFW consumes less power, time, and cost than conventional fusion welding processes. Bindal et al (2021) studied the effects of welding pressure and rotational speed on the joint overlap distance and weld strength for polypropylene parts welded in a shear type joint configuration. Spin time, spin initiate distance and pressure are preset.…”

Rotary friction welding (RFW) is a highly efficient and sustainable process for joining both metals and plastics. The welding process parameters of RFW must be carefully selected to ensure a good quality weld with minimum energy consumption. Few studies in the literature simulate RFW of plastics and none aim to optimize the welding process parameters. This study aims to optimize the process parameters of the continuous drive rotary friction welding of high-density polyethylene (HDPE) pipes. To simulate the RFW process, a 2D axisymmetric fully coupled thermo-mechanical model was developed using DEFORM software package. The model used an elastic-plastic material behavior model that varies with temperature, strain, and strain rate, and a temperature-dependent coefficient of friction. The material behavior was modeled using a Zerilli Armstrong equation and the 2D model was validated against experimental data from the literature. The model successfully predicted the material behavior and captured the thermal and mechanical behavior of HDPE during the welding process. The model was then used to optimize the process parameters of the RFW of HDPE pipes using the Taguchi method. A linear regression model was used to estimate the response in terms of the input process parameters for a specific pipe geometry of 63 mm diameter and 5.8 mm thickness. The optimized process parameters that minimized the power consumption for the selected pipe were found to be 800 RPM rotational speed, 20mm/min feed rate and a friction time of 9 seconds. By relying upon these optimized parameters, industry professionals can produce high quality HDPE welds which would result in a reduction in welding operations cost, and a shift towards more sustainable manufacturing operations.
