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
-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
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
|Thickness to weld||Welding type||Tool ref|
|1 to 3 mm||Butt, overlap, T-shape||F-HSA-2-X|
|2 to 4 mm||Butt, overlap, T-shape||F-HSA-3-X|
|3 to 6 mm||Butt, overlap, T-shape||F-HSA-4-X|
|5 to 8 mm||Butt, overlap, T-shape||F-HSA-5-X|
