2. Computational weld mechanics - Increased accuracy in fatigue assessment, distortion and residual stress analysis
Sammanfattning : This thesis work is concerned with the mechanical response of welded steel structures, which are distortions, residual stresses, and fatigue. The accuracy of fatigue assessment, distortion and residual stress analysis using Computational weld mechanics (CWM) is focused. LÄS MER
3. 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.

4. Modeling and Simulation of Weld Hot Cracking
Sammanfattning : Several alloy systems are susceptible to weld hot cracking. Weld hot cracking occurs by fracture of liquid films, normally grain boundary liquid films, at the late stage of the solidification of the weld. The cracks can be small and therefore difficult to detect by nondestructive test methods. LÄS MER
5. Signal processing and high speed imaging as monitoring tools for pulsed laser welding
Sammanfattning : In Laser Materials Processing there has always been a need for suitable methods to supervise and monitor the processes on line, to ensure correct production quality or to trigger alarms when failures are detected. Numerous investigations have been made in this field, including experimental and theoretical work. LÄS MER
