Abstract A three dimensional coupled thermomechanical finite element model (FEM) is proposed. The aim is to simulate the friction stir welding (FSW) process of high density polyethylene (HDPE) materials. An optimisation study using a full factorial design has made it possible to distinguish the effects of welding parameters. The parameters taken into account are taken on two levels, the tool rotational speed, shoulder diameter, and pressure exerted by the tool. The temperature values generated by different combinations of parameters are analysed and the combination of optimal parameters is determined. Results show the dependence of maximum temperature on rotational speed. The generated temperature at the joint essentially determines the weld quality and tensile strength. Thus, a target temperature below the melting point of HDPE can be achieved through careful choice of FSW welding parameters.
