In this 4.5-minute video, watch MTI’s Model RM-1 friction stir welding machine demonstrate a steel butt weld between two flat materials. You’ll see the rotating pin tool generate frictional heat, penetrate the bond line, and mechanically “stir” the steel together to form a solid-state joint with strength and consistency. This detailed demonstration highlights how FSW can join steels without melting the base metals—producing low-distortion, high-quality welds suitable for demanding production and contract environments.
