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

The challenge :

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

  • Higher welding efforts than with common aluminium alloys.
  • Cyclique fatigue and stronger abrasion wear.

STIRWELD answer

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

 

  • Reinforced quality control
  • Performance
  • Traceability
  • Tool price optimization.

Case study : riveting versus FSW welding

  • Cheaper and faster  (single manufacturing step)
  • Lighter (reduction of assembly thickness)
  • High mechanical resistance, particularly fatigue
  • Perfectly sealed

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