A review on friction stir welding of thermoplastic materials: Recent advances and progress

摘要: Friction stir welding (FSW) was developed initially for welding aluminium alloys which were difficult to weld using conventional welding techniques, and a remarkable success was accomplished in these alloys and other wide range of metals. Then, this technique has been applied without any modifications for welding polymeric materials. As a result, conventional FSW of polymeric materials did not achieve satisfactory joint strength due to the huge differences between the properties of metals and thermoplastic materials. As a …
