Description
Increasing global requirements regarding CO₂ emissions are forcing manufacturers in many industries to develop lighter and more environmentally friendly products and structures. The use of low-weight materials such as aluminum, magnesium, and polymers can significantly reduce greenhouse gas emissions.
Friction Stir Welding (FSW) is one of the most innovative joining methods developed in recent years. It is mainly used for aluminum alloys, but due to its advantages it is increasingly applied to thermoplastic polymer materials. The method has been successfully used for joining polyamide (PA), polyethylene (PE), polypropylene (PP), polycarbonate (PC), polyvinyl chloride (PVC), polyethyleneterephthalate (PET), and others.
Polyamide is one of the polymer materials with wide engineering applications in mechanical engineering, the automotive and food industries, shipbuilding, energy, and other sectors. However, limited information is available regarding the FSW of polyamide and the influence of welding modes and tools on the quality of the produced joints. Therefore, further research is required. The selection of an appropriate combination of process parameters and tool design is crucial for achieving high-quality joints with suitable mechanical properties.
The aim of this work is to investigate the influence of welding process parameters on the mechanical properties of polyamide (PA6) welded joints using a hot stationary shoulder tool.
