This video highlights MTI’s Model LS-1 friction stir welding system in action. The 7.5-ton Model LS-1 FSW machine delivers up to 67 kN of spindle welding force at 3000 rpm. This makes it ideal for demanding production and research applications.
You’ll see coordinated motion and robust performance as the LS-1 produces long friction stir welds across various materials and geometries, demonstrating its ability to support linear welding speeds up to 5000 mm/minute and seams up to 55 feet on complex part combinations.
Ideal for laboratory research, prototyping, or full-scale production, this FSW machine demonstrates the precision, strength, and repeatability that friction stir welding brings to automated manufacturing environments.
