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.
Our innovative design limits the use of expensive materials while guaranteeing performance and meeting the requirements of welding specifications.
- Reinforced quality control
- 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.
We offer tools according to the following characteristics :
HIGH STRENGHT ALUMINIUM ALLOYS
|Thikness to weld||Welding type||Tool ref|
|1 to 2 mm||Butt, overlap, T-shape||F-HSA-1-X|
|2,1 to 4 mm||Butt, overlap, T-shape||F-HSA-2-X|
|4,1 to 6 mm||Butt, overlap, T-shape||F-HSA-3-X|
|6,1 to 8 mm||Butt, overlap, T-shape||F-HSA-4-X|
