Friction Stir Welding

Friction Stir Welding (FSW) is a technique used to join metal pieces together without melting them. A specialized rotating tool, made of a solid material, is pressed into the joint area between two metal surfaces. The friction from the tool’s rotation generates heat, softening the metal without melting it. The tool then moves along the joint, stirring the softened material and creating a strong, solid weld as it cools. This process produces high-quality joints with minimal defects, making it ideal for lightweight and high-strength applications such as aerospace and automotive manufacturing.
