1. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design
Abstract : 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. READ MORE

2. Simulation of robot paths and heat effects in welding
Abstract : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. READ MORE

3. Computational weld mechanics - Increased accuracy in fatigue assessment, distortion and residual stress analysis
Abstract : 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. READ MORE

4. Inductive measurement of narrow gaps for high precision welding of square butt joints
Abstract : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. READ MORE

5. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature
Abstract : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. READ MORE
