11. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design
Sammanfattning : There is a strong industrial need for developing robust and flexible manufacturing methods for future light-weight design. Better performing, environmental friendly vehicles will gain competitive strength from using light weight structures. LÄS MER
12. High speed imaging analysis of laser welding
Sammanfattning : Laser welding is often considered a new and exotic manufacturing method even though it has been used in industrial applications for nearly fifty years. In the early years only a few special applications justified the high investment cost involved, but as the price of the laser sources has reduced, industrial interest in laser welding has increased.

13. Fatigue Strength of Friction Stir Welded Joints in Aluminium
Sammanfattning : Solid state Friction stir welding (FSW) is of major interest in the welding of aluminium since it improves the joint properties. Many applications where Al-alloys are used are subject to varying load conditions, making fatigue failure a critical issue. LÄS MER
14. Multi-axial fatigue of welded details
Sammanfattning : Welds and welded joints are nowadays very common in steel structures. Since thewelded parts also are susceptible to fatigue, they can have a major influence on thetotal life of the structure. LÄS MER
15. Individualizing assembly processes for geometric quality improvement
Sammanfattning : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it usually increases production costs. LÄS MER
