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.
