1. Welding of Heavy Structures Subjected to Fatigue
Abstract : Welding is a key process for heavy steel structures, but it is also a weak link of the structure since fatigue fractures in welds are a common cause for failures. This thesis proposes several changes in order to improve the fatigue properties in a cost effective way. READ MORE

2. Improved CWM platform for modelling welding procedures and their effects on structural behaviour
Abstract : A welding procedure specification is the document describing how a weld joint should be constructed. Arc weld processes are characterized by transient thermal behavior, leading to rapid changes in material properties and dynamic interaction between weld and base material. READ MORE

3. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds
Abstract : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. READ MORE

4. Residual Stress Analysis and Fatigue Assessment of Welded Steel Structures
Abstract : This doctoral thesis is concerned with fatigue life of welded structures. Several topics related to fatigue of welded structures are treated such as; weld defects and their influence on fatigue performance of welded structures, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, welding simulation, residual stress prediction and measurement and their influence on fatigue life.

5. Fatigue properties of cut and welded high strength steels : Quality aspects in design and production
Abstract : This doctoral thesis concerns fatigue of welded structures. Welding is one of the world’s most common joining methods and it is frequently used in several structural applications in many fields. Some examples are construction vehicles, loader cranes, trucks, busses, forestry and agricultural machines, bridges and ships. READ MORE
