This video demonstrates the MTI Model RM-1 friction stir welding machine delivering 67 kN of welding force to produce high-quality solid-state welds. By using its rotating tool to generate frictional heat and mechanically “stir” the materials together across the bond line, the FSW process creates a fine-grain microstructure with mechanical properties that closely match—or even exceed—those of the original materials.
This capability makes the RM-1 an excellent choice for research and development, especially when exploring optimal bimetallic applications, material combinations, and joint geometries.
