FSW (Friction Stir Welding) technology

Friction Stir Welding (FSW) technology is applied to Mazak’s hybrid multi-tasking machines. All processes from raw material to finished workpiece can be done in one machine.

Friction Stir Welding is a joining process that uses frictional heat generated by a rotating tool to join two metal plates.
Unlike conventional welding methods, FSW does not use fusible materials, or melt the workpiece.
FSW is well-suited for joining alloys with low melting points, including aluminum, copper and brass, as well as handling high-temperature welding in steels and nickel-based alloys.
Joint strength becomes higher, and distortion becomes smaller than conventional welding methods.
FSW creates safer working environment as it does not produce gas, fume, or spatter.

Advantages of FSW

  • Creates full-penetration, defect-free welded joints with greater strength than conventional welding methods
  • Able to join not only the same base metals, but also different types of metals
  • Environmentally friendly; no fumes, dust, spatter, plasma or X-rays
