This video demonstrates the MTI Model GG-7 friction stir welding machine in action. Watch how it delivers 67 kN of welding force to produce high-quality solid-state welds across a range of part geometries. You’ll see the system weld a 15 mm-thick plate, a 2.5 mm-thick plate, and a 15 mm-thick dome, showcasing FSW’s ability to handle both thin and thick materials with exceptional consistency and mechanical performance.
These capabilities make the GG-7 ideal for rail components and production contract welding environments, where strength, repeatability, and low distortion are critical.
