Friction Welding is a solid-state welding process that joins materials by generating heat through mechanical friction. In this method, one workpiece is rotated against another stationary piece under pressure. The friction creates heat, softening the materials at the interface, allowing them to bond as they are pressed together. This technique is commonly used for joining metals and thermoplastics, offering advantages like minimal distortion and no need for filler materials. Friction Welding is particularly useful in industries such as automotive and aerospace, where strong, lightweight joints are essential for performance and safety.
