FSW tools for Aluminium-Copper welding
The challenge :
FSW of copper leads to a temperature of 900°C into the weld.
Classic FSW tools can not support this high temperature and results in very low lifetime.
STIRWELD answer :
We have developed FSW tools which withstand high temperatures during welding. Stirweld’s tools are made of heat resistant materials. Copper FSW tools is used in efficient water heat sink and bus bars for electrical applications.
Available in smart version (temperature recording during welding)
Case study : Liquid cold plate in copper
-Perfect seal on the first try
-Less deformation than conventional fusion welding
-High mechanical strength
-Perfect thermal conductivity in the weld
FSW is the only process today that combines perfect sealing, mechanical and thermal performance on copper liquid cold plates.
We are able to deliver tools according to the following characteristics :
|Thickness to weld||Welding type||Tool reference|
|1 to 3 mm||Butt, overlap, T-shape||F-CU-1-X|
|2 to 4 mm||Butt, overlap, T-shape||F-CU-2-X|
|3 to 6 mm||Butt, overlap, T-shape||F-CU-3-X|
Our catalogue lists our standardized tools. We also offer specific tools developed according to your application and tailor-made in “fix pin” or “retractable” version.
