1. Human Lean : Combining Sense of Coherence and Lean to achieve productivity and health
Abstract : The purpose of this thesis is to identify barriers to and supportive factors for Lean implementation and to investigate how application of the Sense of Coherence (SOC) theory combined with Lean philosophy may affect health and productivity. The thesis is based on five studies. READ MORE

2. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties
Abstract : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. READ MORE

3. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101
Abstract : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. READ MORE

4. Prefabricated composite bridges : a study of dry deck joints
Abstract : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

5. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam
Abstract : Duplex stainless steels (DSSs), with a ferritic-austenitic microstructure, are used in a wide range of applications thanks to their high corrosion resistance and good mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding of the relations between composition, processing thermal cycles, resulting microstructures and properties.
