1. Friction stir welding of copper canisters for nuclear waste
Sammanfattning : The Swedish model for final disposal of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. One of the methods to seal the copper canister is to use the Friction Stir Welding (FSW), a method invented by The Welding Institute (TWI). LÄS MER
2. Robotic Friction Stir Welding for Flexible Production
Sammanfattning : Friction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. LÄS MER
3. Feedback Control of Robotic Friction Stir Welding
Sammanfattning : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.

4. Robot system for flexible 3D friction stir welding
Sammanfattning : Applying Friction Stir Welding (FSW) on complex joint geometries requires not only a machine with 3-dimesional work space capacity, but also a sound definition of the part geometry as well as knowledge about the process. Having a joining process, such as FSW, with great characteristics from both seam quality and environmental perspective, but yet only a minor presence in the manufacturing industry may be related to flexibility and cost issues.

5. Investigation and modelling of friction stir welded copper canisters
Sammanfattning : This work has been focused on characterisation of FSW joints, and modelling of the process, both analytically and numerically. The Swedish model for final deposit of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. LÄS MER
