“…This explains why polymers are usually characterized by a melting range instead of a melting point. Some previous studies [9] concluded that a traditional FSW tool is not appropriate for welding polymers due to the low melting point, thermal conductivity and hardness of polymeric materials [10]. Thereby, since the tool plays a crucial role in the FSW process, the development of adequate FSW tools for polymers is considered a topic that must be addressed with high determination.…”

Friction stir welding (FSW) is relatively a new welding method where heat generated by friction is used to forge components together under an axial force. In this method, the generated heat does not exceed the material melting point, instead, the material is heated to its forging temperature and is stirred together by a rotating tool. Since the invention of FSW, this technique has been mainly used for welding aluminium plates together for butt and lap joint configurations.This study is focused on welding lap joint of dissimilar polymers with a new developed tool, in order to evaluate the effect of the welding parameters on the weld strength. This paper describes the process of developing a stationary FSW tool for welding thin plates of polypropylene and polyethylene. The welds produced with this tool improved the welds surface quality and strength significantly. The use of the proposed tool showed to improve the stability in the axial force magnitude during the welding procedure in comparison with a conventional FSW tool. It was also concluded that the rotational and traversing speed have the most effective role regarding the overall specimen tensile strength. Moreover, unlike lap joint of metallic materials, the defect occurred in the retreating side of the welds.

“…Shelley (2007) reported that potential applications of friction stir welding include sealing packages within the electronics and photonics industry, and welding aluminum foil for use in the aerospace industry. Scialpi et al (2009) has successfully friction stir welded plastics. A schematic illustration of the friction stir spot welding process is shown in Fig.…”

“…The Welding Institute patenting FSW modified the original process for welding polymers, using a vertically vibrating sheet instead of rotating tool for producing polymeric seams 7. Nelson, however, in his patent suggests geometrical features for the surfaces of rotating tools, to be used with polymers according to the original FSW method 8…”

The bond strength and the heat affected zone (HAZ) of friction stir welded seams made of poly(ethylene‐terephthalate‐glycol) are analyzed in the article. The seams were prepared with various settings (rotation speed and feeding rate) and with various welding tools. Using the welding parameters (rotation speed, the feed rate, and the tool diameter) a K‐factor characterizing the welding process was defined. The novel K factor is related to the welding heat input, which is in direct correlation with both the range of the HAZ and the mechanical properties of the seam. The HAZ formed was analyzed by stress optical method, the mechanical properties by flexural test. It has been demonstrated that the efficiency factor of the welded joint is closely related to the width of the HAZ and it depends on the welding parameters and the tools. © 2012 Wiley Periodicals, Inc.
