Friction Stir Welding
 - Quality in Depth

Cleaner, leaner, stronger

In contrast to conventional welding techniques, the FSW process requires no filler material, gas or other consumables - and consumes much less energy. Generating no harmful gases, no slag, no spatter and little sound, the process actively contributes to a better working environment, while simultaneously boosting productivity. Best of all, weld-strength quality is excellent.

FSW opens up whole new areas in welding technology. Rapid and high quality welds of aluminum 2xxx and 7xxx series alloys, as well as copper and magnesium - traditionally considered unweldable - are now possible. 

Key Benefits

  • No joint preparation - degreasing only
  • High quality welds
    - Increased tensile strength
    - Outstanding fatigue properties
    - Corrosion resistance
  • Environment friendly
    - No arc, fumes or spatter
  • Low operational cost
    - No consumables and low energy costs
  • No post treatment
    - Low distortion and shrinkage



The FSW process has demonstrated its capabilities and been approved for joining aluminum and other metals. ESAB FSW technology is since 1996 in use across a wide industrial spectrum of applications:

  • Aero
  • Automotive
  • Railway
  • Space
  • Transportation
  • Marine
  • Heat transfer
  • Nuclear
