FSW Tools for High Strength aluminum : Al 7xxx and Al / Li

The challenge :

For these demanding aluminiums and demanding alloys with a high mechanical resistance, our clients have encountered two major issues: 

  • Higher implementation efforts than with common aluminium.
  • Cyclique fatigue and abrasion are stronger.

STIRWELD’s answer

Our innovative design limits the use of expansive materials while guaranteeing performance and meeting the requirements of welding specifications. 

  • Reinforced quality control
  • Performance maintenue
  • Traçabilité garantie
  • Tool price optimization.

Case study : riveting versus FSW welding

  • Cheaper and faster  (one single stage of manufacture)
  • Lighter (reduction of assembly thickness)
  • High mechanical resistance, particularly mechanical fatigue
  • Anti-corrosion, thanks to the use of aluminium
  • Perfectly sealed

The replacement of riveting by FSW welding  is spreading in the aerospace sector.
