Friction stir welding (FSW) is an advanced joining technology specifically developed for welding materials that are difficult to weld (e.g. polymers). Over the last two decades, more and more research has been published on the applicability and development of the technique on polymeric materials. The aim of the present study is to investigate the applicability of the method for welding polymeric materials and to analyse the effect of the parameters of FSW. In the tests, 4 mm thick polypropylene sheets were welded by varying two welding parameters (tool speed (n) and feed rate (vf)) in four levels. Thus, a complete experimental design with 16 measurement points was created. During the welding process, the force components on the tool/workpiece were measured, from which the resultant welding force was calculated and the strength of the joints was characterized by tensile testing. The ratio of the tensile strength of the joints and the tensile strength of the material were used to characterise the process in terms of joint efficiency. During welding, the axial force component (Fz) was the dominant force value. The resultant forces (Fe) decreased with increasing n, while they increased with increasing vf. The tensile strength of the joint, and hence the bonding efficiency, improved with increasing n, while it deteriorated with increasing vf. The ratio derived from the ratio of n to vf was also analysed, with an increase in the ratio showing a decreasing trend in the resulting weld strength and an improving trend in the bonding efficiency.

“…Polyethylene sheets including HDPE and HIPS were welded with FSW, and their mechanical features were examined; consequently, an innovative procedure to produce nanocomposite polymers is recommended. The strength and weakness of PS-welded polymer materials has been investigated [16]. The tool and shoulder profile plays an essential role in the FSW process [17,18].…”

the purpose of this project was to introduce a way to improve the mechanical properties of welded dissimilar material, which gives benefits such as affordable, high speed, and suitable bond property. In this experimental project, the friction welding method has been applied, including combining parameters, such as numerical control (NC) machine including two different speeds, and three different cross-sections; including flat, cone, and step surfaces. When the welding process was done, samples were implemented and prepared via bending test of materials. the results have shown that, besides increasing the machining velocity, the surface friction increased, and so did the temperature. By considering the stated experimental facts, the melting temperature of composite materials has increased. This provides the possibility of having a better blend of nanomaterial compared to the base melted plastics. Thus, the result showed that, besides increasing the weight percentage (wt %) of Nanomaterials contents and machining velocity, the mechanical properties have increased on the welded area for all three types of samples. This enhancement is due to the better melting process on the welded area with attendance of various Nanoparticles contents. Also, the results showed that the shape of the welding area could play a significant role, and the results also change drastically where the shape changes. Optimum shape in the welding process has been dedicated to the step surface. The temperature causes the melting process, which is a significant factor in the friction welding process.

Acrylate Polymers for Advanced Applications

Due to limitations of injection molding of polymer/plastic materials, complex plastic parts are often assembled from two or more injection-molded components. Joining of polymers can be achieved by chemical-based technologies and thermal methods such as welding. Welding technique is one of the important manufacturing routes that can be used to refine product design and reduce production cost. Plastic welding processes typically involve heating the joining faces to induce localized melting and subsequently applying pressure to cause molecular diffusion at the molten interface, which produces a solid weld upon cooling. The need for an effective welding process that is fast, accurate, and with no relative part movement has fueled the development of laser-transmission welding (LTW) technology. LTW is an innovative joining process for acrylate materials. The quality of weld highly depends on correct selection of process parameters in LTW. The systematic study and analysis are required to conduct LTE process economically and efficiently. In the present chapter, current prospects of applications of acrylates and joining of them using LTW has been analyzed. The main emphasis has been given to analyze the variations of quality performance characteristics with varying input welding factors and concluding remarks has been drawn from present work. From this study, it is observed that acrylics are future innovative industrial materials, which need to be joined to create complex features on them. Welding of acrylics using LTW to achieve better and more economical weld performance is still under continuous research by scientists/industrialists.
